Notes and Exhibitions

Plagithmysis blackburni (Sharp) and P. greenwelli Gressitt and Davis: Live adults of Plagithmysis blackburni (Sharp) on mamani, Sophora chrysophylla (Salisb.), from Mauna Kea on the Big Island and a color photo of the new native Plagithmysis greenwelli Gressitt and Davis were exhibited by Dr. Gressitt. Phormia regina (Meigen), the black blowfly: Larvae removed from open wound in eye of cow on Parker Ranch, Hawaii was identified by Dr. Hardy as Phormia regina. Some adults were reared by Dr. Prehal, ranch veterinarian, 5 December 1969. The identification was confirmed by Dr. M. T. James, who said, "the record is an interesting though not by any means an unusual one." Note presented by Dr. D. E. Hardy. Phaenicia sericata (Meigen) or cuprina (Wied.): Second and third instar larvae of Phaenicia, probably sericata, were recently referred to me by Gilbert Masaki, Roach Control Service, which had been removed from the ear of a patient at Hale Nani Hospital. This was an old man with a chronic ear infection which was discharging a foul smelling fluid to which the were attracted for oviposition. The larvae were ap parently feeding as scavengers. The attending physician said he had frequently seen cases of maggots infesting wounds. Note presented by Dr. D. E. Hardy. Chrysomyia megacephala (Fab.): Large numbers of Chrysomyia megacephala (Fab.) and some Phaenicia cuprina (Wied.) were reported in festing the wards, kitchens and surgical rooms of Queens Hospital. This had gone on for about five days and seemed to coincide with the cool weather. Mr. Gilbert Masaki, Roach Control Service, investigated this and reported that the flies were being attracted in large numbers to the blossoms of the Gular trees (Sterculia urens) on the hospital grounds and were flying into the hospital rooms from the trees. Note presented by Dr. D. E. Hardy. acuta (Walker): During the course of fruit parasite trapping, several cylindrical mesh traps coated with sticky Tree Tanglefoot using different kinds of baits; namely, oranges and blended raisins with honey, were set up at several locations on both windward and leeward Oahu and on Tantalus Drive near one of the tributaries of the Kanealole Stream at an approximate elevation of 300 m. Vol. XXI, No. I, August, 1971 3

Examination of traps set on Tantalus Drive on 24 December 1969 and 7 January 1970 showed a number of the torpedo bugs, Siphanta acuta (Walker). No S. acuta was found on traps set up elsewhere. Earlier accounts of this flatid (Perkins, 1913 cited in Zimmerman, 1948) indicated that this immigrant, which was established in Hawaii prior to 1898, became extremely numerous by 1900, and was diminishing in many localities following the introduction of a Scelionid egg parasite, Aphanomerus pusillus Perkins, by Koebele in 1904. It is noteworthy that these flatid bugs were not accidentally trapped for there was no earlier record of the swarming habit. The data obtained were not sufficient for analysis to determine whether there were differences in the attractiveness of the baits. It is, however, interesting that these homopterous were attracted to baits. Note presented by Mr. Banpot Napompeth. Mr. G. A. Samuelson exhibited a new publication entitled, "The Directory of Coleoptera Collection of ," edited by Ross Arnett and G. A. Samuelson. Opius melanagromyzae Fischer and Opius sp.: The bean fly parasites, Opius melanagromyzae Fischer and Opius sp., are now widely established in 12 different areas around Oahu. Last month they were also recovered at Waikapu, Maui and Kaumakani, Kauai from releases made in August 1969. These braconids were introduced from Uganda, East Africa through the cooperation of Dr. D. J. Greathead, Common wealth Institute of Biological Control in April 1969. Note presented by Mr. Sun Hin Au. (Herrich-Schaeffer): Large numbers of the rhopalid bug, Jadera haematoloma (Herrich-Schaeffer), were found feeding on fruits and seeds of golden-rain tree, Koelreuteria formosana, at Kona, Hawaii early in January 1970 by Ernest Yoshioka for a new host and island record; previously reported only on balloon vine on the islands of Oahu and Kauai. Schistocerca vaga (Scudder): A female of the vagrant grasshopper, Schistocerca vaga (Scudder), was captured by Nobuo Miyahira in a pas- tureland at Makena, Maui on 19 January 1970. This large grasshopper now has been found on all inhabited islands, except Hawaii and Niihau. Notes presented by Mr. George Funasaki. Program: Dr. Bess, Program Chairman, introduced Dr. Asher Ota, who gave a very interesting slide and talk presentation on "Current Re search of the New Guinea Sugarcane Weevil Borer." Dr. Ota was com plimented on the professional quality of his slides.

February The 770th meeting of the Hawaiian Entomological Society was called to order by President A. W. Morrill, Jr. on 17 February 1970 at 4 Proceedings, Hawaiian Entomological Society

2:00 p.m. at Agee Hall, HSPA Experiment Station. Members Present: S. H. Au, W. T. S. Au, Balock, Beardsley, Bess, C. F. Clagg, H. B. Clagg, Chambers, Davis, Delfinado, Drake, Goff, Gressitt, Haramoto, Hardy, Howarth, Joyce, Khoo, LaPlante, Leach, Leeper, Mau, Montgomery, Morrill, Nakata, Napompeth, Navvab- Gojrati, Olson, Pemberton, Raros, Schroeder, Sherman, Shiroma, Steffan, Tamashiro, Tenorio, Woolford, and Hyo-sok Yu. Visitors Present: Dr. G. G. E. Scudder. President Morrill waived the order of business to permit Dr. Gressitt to make an announcement so that he could keep an appointment with the Governor. Dr. Gressitt reported that Governor Burns is considering the proposal by his Committee for the Preservation of Scientific Areas for a HAWAII NA TURAL RESERVES SYSTEM. It is hoped that it will be incorporated into the proposed office of Environmental Quality. Three members of the committee are meeting with the Governor this afternoon. The Governor used some of the suggestions of the committee for his Niihau plan. Reports of Officers and Committees: Membership Committee Report: Dr. Frank Haramoto introduced 13 new members for ratification by the Society membership. The Society ratified the following: Mr. William Bernard Andrews, Jr., Mr. Wendell Teong Sum Au, Mr. Sing Kwong Chuo, Mrs, Anita Nobuko Gillogly, Mr. Kenneth Fukio Kawamura, Mr. Bin Khong Khoo, Mr. Po-Yung Lai, Miss Eugenia Casubha Manoto, Mr. Steven Lee Mont gomery, Mr. Clifford S. Oda, Dr. Frank Jay Radovsky, Mr. Victor Mitsuo Tanimoto, and Mr. Hyo-sok Yu. Constitution Committee Report: Mr. F. J. Olson reported that 91 ballots were mailed or sent to Society members within the state and 55 were returned—all voted "YES" for acceptance of the amended con stitution. There were no negative votes. The new constitution was unanimously accepted. Executive Committee Report: Mr. C. J. Davis reported the results of a meeting with Mr. Tom Tagawa, State Forester, Department of Land and Natural Resources, who had sought Society help in controling noxious weeds in the native forest by using biological methods. Eight of the ten weeds alluded to by Mr. Tagawa were biocontrol targets of the Entomo logy Branch of the Hawaii Department of Agriculture. The weeds are: banana poka (no biocontrol), blackberry, bull thistle, Hamakua pamakani, lantana, clidemia, firebush (no biocontrol), Rhodomyrtis tome?itosa, Gorse, and Christmas berry. Mr. Tagawa asked for closer liaison with the Society. President Morrill announced the next Society meeting would be held in conjunction with a Mosquito Control "rump" session at the Bishop Vol. XXI, No. I, August, 1971 5

Museum at 2:00 p.m., March 3, 1970. President Morrill appointed Drs. Gressitt, Hardy, and Mr. C. J. Davis to the Liaison Committee—Mr. Davis, chairman. Paper: Mr. F. J. Olson submitted a paper entitled "Pathologies of the New Guinea Sugarcane Weevil Grub, Rhabdoscelus obscurus (Boisduval) (Coleoptera: Curculionidae), Caused by the Tarasitoid' Cane Weevil Tachinid, Lixophaga sphenophori (Villeneuve) (Diptera: Tachinidae)."

Notes and Exhibitions

Steven Montgomery exhibited pictures of damage to Hawaii's native forests caused by grazing mammals. Rhabdoscelus obscurus (Boisduval): Four palm trees, two young, vigorous Pritchardia sp. and two old, declining Phoenix canariensis Chabaud have been heavily attacked by the sugarcane borer on the grounds of the Bishop Museum recently. The Pritchardias will probably recover in due time, but one of the Phoenix has apparently died as a result of the attack, and the second one has been cut down while still living but in obviously poor shape. The damage, as of 30 January consisted of ex tensive tunneling by beetle larvae on the lower portions of the leaf stems, and in the living palms there was no indication that the tunnels penetrated towards the growing point of the palm. The attack had been in process apparently for weeks or months, as most of the beetles had emerged from the tunnels and were resting as adults in the axils of the leaves. One or two cocoons with puparia of the New Guinea tachinid, Lixophaga sphenophori, were found in the living Pritchardia, but the total parasitism was obviously too low to protect the trees effectively. Note presented by Mr. Fred Bianchi. Orthomecyna mesochasma Meyrick: Adults of this small cram- bib are presently abundant at lights in Lihue, Kauai, and a long series of them has been collected by Mr. Donald Sugawa, of the State Entomology Branch. The species is of interest because it is endemic to Kauai and was reared on one occasion from a caterpillar found on the roots of sugarcane. It is not normally an abundant . Note present ed by Mr. Fred Bianchi. Melanaspis aliena (Newstead). Dr. Beardsley reported that he recently discovered two specimens of this armored scale insect which were collected at Hiiose Nursery in Hilo, Hawaii, 19 June 1956, by Q. C. Chock, ex Cymbidium orchid. The specimens had been collected during a survey for another orchid scale Lepidosaphes tuberculata Malenotti, conducted by the State Department of Agriculture, and were among several lots of scale specimens which were submitted for identification at that time. M. aliena has not previously been reported in Hawaii, but it is widely distributed in the American tropics, having been recorded from orchids, mostly Cattleya spp., in Florida, Cuba, Mexico, and Guatemala. It was 6 Proceedings, Hawaiian Entomological Society

described from specimens on Cattleya in a greenhouse in London, England. Apparently this species is not a serious orchid . Whether it is still present in Hawaii is not known. Note presented by Dr. J. W. Beardsley. Chlorichaeta albipennis (Loew): Adults of the ephydrid, Chlo richaeta albipennis (Loew) were observed attracted to the eyes of a dog near Opaeula Pond, Makalawena Tract, N. Kona, Hawaii, 13 February 1970. The dog was very old and the eyes were obviously diseased. The flies were apparently feeding on the suppurating fluid coming out from around the eyes. Identification made by Mr. J. Tenorio, who stated that he has seen a note in the literature concerning another species of Chlorichaeta attracted to sores on camels in Egypt. Note presented by Dr. D. E. Hardy. Chironomus esakii Tokunaga: Mr. G. Funasaki reported that Chironomus esakii Tokunaga has been placed as a synonym of Chironomus crassiforceps K. Seven adults collected in Waipahu, Oahu in November 1967 were returned with the determination Chironomus crassiforceps K. (=esakii Tokunaga). Determination was made by W. W. Wirth, USNM. Plaesius javanus (Erichson): Mr. Sun Hin Au exhibited a

one year. Alydus pilosulus (Herrich-Schaeffer): This determination was recently received for a specimen of an alydid bug collected by sweeping grass around General Lyman Field, Hilo, Hawaii, by Benjamin Hu on 6 November 1966. This constitutes a new locality record for this bug which was previously reported only from the island of Oahu. Deter mination was made by J. L. Herring of the U. S. National Museum. Note presented by Mr. Ed Shiroma. Nasonovia ribisnigri (Mosley): This determination was recently received for 24 specimens of collected on flower head of Crepis japonica from Puulau, Hawaii, by Benjamin Hu and George Fukumura on 6 December 1964. Determination was made by Miss L. M. Russell. This constitutes a new record for the State. "Keys to the Insects of the European U.S.S.R., Vol. 1", by G. Ya. Bei-Bienko et al. 1964, gives Vol. XXI, No. I, August, 1971 7 a brief account of this aphid. It's hosts are listed as various species of Ribes and Grossularia reclinata, on ends of young shoots and on lower sides of leaves. It migrates to Compositae (Cichorium, Hieracium, Crepis, Sonchus, Lactuca, Arnoseris, Lampso?ia, etc.) and on Scrophulariaceae (Veronica), and also Cruciferae (Alliaria), on lower sides of leaves. It is sometimes in jurious. This aphid is found everywhere in the North at least to the Khibiny Mountains, Transcaucasia, Soviet Central Asia, and Western Europe. Note presented by Mr. Ed. Shiroma Disaphis tulipae (Boyer de Fonscolombe): This determination was also received recently for 2 aphids collected on carrot leaves from Hilo, Hawaii, by Benjamin Hu on 4 March 1965. This constitutes another new aphid record for the State. Determination was made by Miss L. M. Russell, who states that they were probably strays on carrot. G. Ya. Bei-Bienko et al. lists this aphid as occurring on Liliaceae and Iridaceae bulbs, and from spring onward on shoots. Distributed from Northwest Soviet Central Asia, Western Europe, Southwest Europe, Southwest and Asia Minor, North Africa, and North and Central America. Note pre sented by Mr. Ed Shiroma. Trox sp.: Several adult specimens of this trogid were picked up in a blacklight trap at Barbers Point Naval Air Station on 29, January 1970. The specimens are much smaller than Trox procerus Har. which was released on Sand Island on 28, November 1966 to control the vagrant grasshopper. Specific determination is not yet known. Note presented by Mr. Ed Shiroma. Program: Dr. Bess introduced Dr. G. G. E. Scudder, from the University of British Colombia, Canada, who gave an interesting presenta tion of "Flight Muscle Polymorphism in Corixidae."

March

The 771st meeting of the Hawaiian Entomological Society was called to order by Acting President Dr. Derrell Chambers on 3 March 1970 at 2:05 p.m. at Bishop Museum. It was held in conjunction with a session of the annual South Pacific Regional Conference of the American Mos quito Control Association. Members Present: Balock, Bianchi, Chambers, H.B. Clagg, Davis, Delfinado, Drake, Gagne, Gillogly, Gressitt, Haramoto, Hardy, Holway, Ikeda, Jackson, Joyce, Keenan, Kitaguchi, Leeper, Look, Mitchell, Nakao, P. Nakagawa, Nakata, Namba, Pemberton, Radovsky, Sakimura, Samuel- son, Schroeder, Shiroma, Steffan, Tanimoto, and Woolford. Visitors Present: Ted Raley, Selma, California, Executive Secretary of American Mosquito Control Association; Gardner McFarlane, Southeast MAD-South Gate, California; W. R. Mitchell N-WMAD, Wheeling, Illinois; Oscar W. Doane, Cape Cod Mosquito Control, Hyannis, Mas- 8 Proceedings, Hawaiian Entomological Society

sachusetts; Arthur A. Dale, CMCA Mosquito Control, Selma, California; David D. Bonnet and Mrs. H. A. Woolford. Membership Committee Report: Dr. Haramoto introduced two new members, Mr. Vernon W. Olney and Mr. Gilbert Joseph Farias. New Business: Mr. Patrick Nakagawa read a draft of a proposed bill from Congressman Spark Matsunaga to Dr. W. Quisenberry of the Department of Health, State of Hawaii, relating to an amendment of the aviation regulations of 1958 on disinsection of aircraft arriving in the United States. It will be submitted for enactment by Congressman Matsunaga. Mr. Wayne Gagne reported that a bill for protection of indigenous fish, bird, and vegetable life is being introduced by Senators McClung, Yoshinaga, Brown, and others to the state Legislature. It reads "No non-indigenous fish, bird, animal or vegetable life shall be imported into the State or transported from any land area within the State except after a public hearing held in conformity with chapter 91 and with the approval of any State office which may be established to preserve the quality and standards of the environment." Mr. Gagne and other students at the University of Hawaii and Bishop Museum are tes tifying for this bill before the legislature. Dr. Gressitt said that it appears the Governor has accepted the pro posal for a Hawaii Natural Reserves System which is being reworded for introduction to the legislature. Program: Acting President Chambers introduced Captain Richard Holway of Preventive Medicine Unit 6, Pearl Harbor, who gave an interesting presentation on Malaria in Vietnam, illustrated by colored slides. The second speaker to introduced was Dr. Charles Joyce of U.S. Public Health Service, who also gave a fine slide show and seminar on interception of mosquitoes on aircrafts in Honolulu and methods of dis insection of aircraft.

Smathers, National Park Service; Tom Tagawa, State Forester; and Herbert Yanamura, agriculture land use specialist, as panelists. For the June meeting, Drs. Mitchell and Nishida will report on an ecology meeting attended on the mainland. Science Fair Committee Report: Mr. Joaquin A. Tenorio presented the following report: The 13th Hawaiian Science Fair was held at the HIC Exhibition Hall on April 2, 3, 4, and 5. There were nine exhibits with an entomological theme. The first place exhibit in this category was entitled: "Overcrowding effects on larval development of the melon fly [Dams cucurbitae)" by Ann Stauffer and Joyce Takayama, University High School, Honolulu, A runner-up was also chosen having an exhibit entitled: "Cat feces—breeding spot for the filth fly" by Howard Wallace, Kalaheo Hillside Intermediate School, Oahu. Executive Committee Report: Mr. Morrill announced that Dr. Asher Ota was selected by the committee to replace Cliff Davis as chairman of the Liaison Committee. Unfinished and New Business: Mr. Wayne Gagne reported that the bill for protection of indigenous fish, bird, animal and vegetable life had received its third reading in the Legislature. He also reported the Natural Areas Bill, Senate Bill 1971 was being received favorably.

Notes and Exhibitions

Lardoglyphus konoi (Sasa and Asanuma): Mites infesting the Dermestes colony used for cleaning vertebrate skeletal material at the Bishop Museum have been identified as L. konoi (Sarcoptiformes: Acaridae). This is the first Hawaiian record of Lardoglyphus (placed in the monogeneric family Lardoglyphidae by some workers). There are 2 described species in the , and I have identified a third in prehistoric Amerindian remains from Nevada. L. konoi was found previously in Japan, India, and England (see A. M. Hughes. 1956. Zool. Mededel., 34: 271-285). In the 2 former countries, it is an economic pest infesting dried sea foods. Like Dermestes, the mite feeds on relatively dry material with a high protein content. The phoretic deutonymph (hypopus) attaches to the beetle larvae and becomes injurious when large numbers of mites build up in the beetle colony. G. A. Samuelson referred speci mens of the beetles to Dr. R. S. Beal, Jr., who writes that they appear "to represent an Hawaiian variant of Dermestes carnivorus Fabricius. I have seen specimens like these only from Oahu." Note presented by Dr. F. J. Radovsky. 10 Proceedings, Hawaiian Entomological Society

Bakericheyla chanayi (Berlese and Trousessart): Collected from a Shama {Copsychus malabaricus, family Turdidae), Honolulu, 19 January 1970, by D. O. Crozier. B. chanayi belongs to the family Cheyletidae (Acarina: Trombidiformes). Bakericheyla and other genera of bird-para sitizing cheyletids have not been recorded in Hawaii previously. B. chanayi is a true blood-sucker (see D. P. Furman and O. E. Sousa. 1969. Ann. Ent. Soc. Am., 62: 858-863). It builds silken nests on the skin of the host, in which all stages of the mite are found. At least under labor atory conditions, it can be distinctly deleterious to the host. The species was first described from Europe, but recent publications include records from California and the Asiatic USSR. This is the first record on Copsychus. B. chanayi is usually associated with certain fringillid species in California, but elsewhere it has been recorded on 7 passeriform families including the Turdidae. Note presented by Dr. F. J. Radovsky. Dacus tryoni (Froggatt): Dr. D. Elmo Hardy exhibited adults of the Queensland fruit fly, Dacus tryoni (Froggatt), and reported that D. tryoni is now established in Tahiti. This species has also recently become established in New Guinea and New Caledonia and is obviously spreading throughout the Pacific. The Queensland fruit fly occurs in Australia and is one of the most dangerous species of fruit flies. It has about the same host range as the oriental fruit fly, D. dorsalis Hendel, and attacks a wide assortment of fleshy fruits. D. tryoni is similar in appearance to D. dorsalis but can be distinguished on the basis of the two costal cells on the wings which are cloudy and not clear as is D. dorsalis. Dr. Bess introduced Dr. Joyce of the U. S. Public Health Service, who gave an interesting talk and slide presentation on quarantine pre- clearance of retrograde cargo returning from South Vietnam.

May

The 773rd meeting of the Hawaiian Entomological Society was called to order by Acting President Dr. Derrell Chambers on 11 May 1970 at 2:05 p.m. at Agee Hall, HSPA Experiment Station. Members Present: Beardsley, Bess, Bianchi, Chambers, Chong, Davis, Drake, Gagne, Gressitt, Haramoto, Hardy, Holway, Joyce, Krauss, LaPlante, Leach, Look, Montgomery, Morrill, Nakata, Olney, Olson, Samuelson, Schroeder, Shiroma, Steffan, Sugerman, Tamashiro, Tani- moto, Tsuda, and Richardson. Visitors Present: Mar. M. A. Ghani (Commonwealth Institute of Biological Science) of Pakistan, Mr. Herbert Kobayashi, and Mr. Gordon Pasfield (Chief of New South Wales Dept. of Agriculture) of Australia. Acting President Chambers waived the order of business and started with the program, pending the arrival of President A. W. Morrill, Jr. Program: Dr. Henry Bess introduced Tom Tagawa, State Forester; Herbert Yanamura, agriculture land use specialist; and Ronald Walker, Vol. XXI, No. I, August, 1971 II

National Park Service, who presented government's philosophy of land use—distinguishing between conservation and preservation. Time did not permit a full debate of the land management problem. President A. W. Morrill, Jr. closed the debate and resumed the order of business. Membership Committe Report: Dr. Frank Haramoto submitted the name of Mr. Darwin S. Yoshioka for membership. Membership was accepted by the Society. Liaison Committee Report: Dr. Asher Ota suggested that the Society send letters of commendation to those legislators who supported bills backed by the Society. It was so moved and the motion was accepted by the Society. Unfinished and New Business: President A. W. Morrill, Jr. read a letter received by Dr. Martin Sherman from Dr. Wallace P. Murdoch, Executive Secretary of the Entomological Society of America, suggesting Honolulu as the site of the 1976 ESA Meeting and Dr. Sherman's reply to Dr. Murdoch indicating that the question would be put to the Society members asking the Society to formally petition ESA to consider Honolulu as the site for the 1976 meeting. Dr. LaPlante so moved and it was se conded. After debate, the motion was accepted by the Society.

Notes and Exhibitions

Dr. J. L. Gressitt submitted the following note: A Colloquium on "Endangered Species of Hawaii" has just been held in Washington, D. C, under auspices of Smithsonian Institution, American Institute of Biological Science, International Biol. Program, Int. Union Conservation of Nature & Natural Resources, Pacific Sci. Association, Pac. Tropical Botanical Garden, U. S. Dept. of Interior, and Int. Council for Bird Protection. Representatives of these organizations, plus University of Hawaii, Bishop Museum and other institutions attended, with some representatives of the Hawaii delegation to Congress at the evening meeting. A telegram was sent to the Hawaii Legislature, the Governor and others, urging passage of the pending bills on Hawaii Natural Area Reserves and movement of introduced to and between islands. A statement has been pre pared for the Press and is being released today in Washington, and in Honolulu to the Star-Bulletin. Copies will go to all members of the State Legislature, higher officials of the State and County governments and others. The statement urges protection of endangered species by pre serving natural areas, cessation of bulldozing of native forests, carrying out research on ecology of native forest and on status and effect of introduced animals and plants, the planting of native trees in already disturbed areas, and other measures. A tentative list of endangered species will be pub lished in Biotropica. Any suggestions for the list should be submitted to J. L. Gressitt by mid-June. 12 Proceedings, Hawaiian Entomological Society

Parlatoreopsis sp.: This is a new armored scale insect (Diaspididae) record for the state. Specimens were collected on twigs of Jasminum sp. at the University of Hawaii during March by J. W. Beardsley. This scale does not appear to be any of the named species of Parlatoreopsis and will be described as new. Identification confirmed by Mr. R. L. Wilkey, California Dept. of Agriculture. Note presented by Dr. J. W. Beardsley. Nysius sp.: An apparently new immigrant species of Nysius (Lygaeidae) was collected on Portulaca oleracea in the Moiliili District of Honolulu. The bugs were found plentiful and breeding on one large Portulaca pJant. Specimens have been submitted to Dr. P. D. Ashlock for determination, but he has not yet positively fixed the species. The genus Nysius is represented in the Hawaiian Islands by around 25 species, all of which are endemic to the islands except Nysius caledoniae Distant which was discovered here in 1964. Note presented by Dr. J. W. Beardsley. Mr. C. J. Davis submitted the following note for Mr. George Funa- saki: A species of Adelgidae was found heavily infesting 50 Pinus pinaster trees at Waikii, Hawaii, 1200 m elevation, on 11 April 1970. This is the first occurrence of the family Adelgidae in Hawaii. Insects in this family are commonly referred to as pine and spruce aphids and they are known to attack only conifers. Dr. J. W. Beardsley, who identified this species as belonging to the family Adelgidae, sent specimens to Miss Louise M. Russell, U.S.N.M., and she determined them as Pineus sp. She suggested specimens be sent to Dr. M. Inouye in Japan or Dr. A. W. Steffan in West Germany for species determination. Specimens were sent to Dr. Inouye. Since Miss Russell would be familiar with the Adelgids of the U. S., this species is probably of foreign origin.

June

The 774th meeting of the Hawaiian Entomological Society was called to order by President A. W. Morrill, Jr., on 8 June 1970 at 2:10 p.m. at Agee Hall, HSPA Experiment Station. Members Present: Balock, Beardsley, Bess, Bianchi, Chambers, Clagg, Davis, Drake, Fujii, Funasaki, Gressitt, Haramoto, Hiramoto, Holway, Howarth, Jackson, Joyce, Kawamura, LaPlante, Lai, Leeper, Mau, Mitchell, Montgomery, Morrill, Nakata, Namba, Olson, Ota, Radovsky, Sakimura, Samuelson, Schroeder, Sherman, Shiroma, Suger- man, Tamashiro, and Tsuda. Membership Committee Report: Dr. J. W. Beardsley moved that Fred Bianchi, Hawaiian Entomological Society member for 40 years, be elected to Honorary Membership upon retirement. The proposal was seconded and accepted by the Society. Executive Committee Report: President Morrill reported that letters addressed to the Governor and legislators who worked for the passage of bills of interest to the Society were held pending signing of the bills into Vol. XXI, No. I, August, 1971 13 laws by the Governor. However, since the Governor has delayed signing the bills, the letters would be sent to the legislators but not sent to the Governor until the bills in question are signed. Old Business: President Morrill read a letter from Dr. W. P. Mur doch, Executive Secretary of Entomological Society of America (ESA), acknowledging receipt of the formal petition sent by the Hawaiian En tomological Society proposing Honolulu as the site for the 1976 ESA Meeting. President Morrill read a letter from Governor Burns thanking the Society for calling his attention to the destruction of native forest in the State reserve area above Laupahoehoe by Blair, Ltd. Dr. Gressitt reported that he and other members of the Committee on Preservation of Scientific Areas inspected 9 areas proposed for inclusion in the Natural Area Reserves System. New Business: Dr. Mitchell gave a detailed report on the progress of the meeting of the Pacific Branch of the ESA to be held at the Surfrider Hotel, 22-25 June 1970. Dr. Mitchell thanked the research and service organizations for contributing histories of their organization. These will be combined, published, and distributed at the Pacific Branch ESA Meeting. Dr. Haramoto briefly outlined the program for the Pacific Branch ESA Meeting followed by a short and sharp pep talk by Dr. Sherman. Dr. Mitchell moved that the Society donate $350 and advance $200 for a petty cash loan for the Pacific Branch ESA Meeting. The unspent balance will be returned to the Society with an accounting of expenditures. This was approved by the Society.

Ophionyssus natricis (Gervais): On 17 May 1970 a boa con strictor {Constrictor constrictor) was found in a hotel room in Waikiki. Num bers of blackish mites were recovered from the snake by Mr. Charles K. Yasuda of the Plant Quarantine Inspection, Hawaii Department of Agri culture, who brought them to the Bishop Museum for identification. All of the collected mites (about 20 specimens, probably representing a small part of the total number on the snake) are 0. natricis (Mesostigmata: Macronyssidae), and this is the first record for this species in Hawaii. These blood-sucking mites are a serious pest in reptile collections, causing harm not only through the amount of blood taken and direct effects of the bite, but more importantly as vectors of a bacterial agent (Aeromonas hydrophila) causing a frequently fatal hemorrhagic septicemia in snakes. There also is evidence that the mite can serve as vector of a haemogregarine and of a filarial worm of snakes. It is perhaps unlikely but feasible that the mite could become established on lizards in Hawaii. There are effective measures available for disinfecting reptiles with this mite, so that 14 Proceedings, Hawaiian Entomological Society a short period of quarantine and treatment would be adequate to ensure exclusion of the species from any snakes or lizards destined for the zoo. In this particular instance the host snake was destroyed. Note presented by Dr. F. J. Radovsky. Pineus pini Koch: The adelgid which was heavily infesting Pinus pinaster trees at Waikii, Hawaii in April 1970 and reported as a new state record at last month's meeting has been determined as Pineus pini Koch by Dr. Motonori Inouye of Hokkaido, Japan. P. pini is a pest of conifers and is widely distributed in Europe. It also is known to occur in Japan, Australia, Tasmania, and New Zealand. Note presented by Mr. G. Funasaki. Trissolcus basalis (Wollaston): Two of seven egg clusters of Plautia stali Scott collected from strawberry guava at Lanikai, Oahu in May 1970 by C. J. Davis yielded adults of the stink bug egg parasite, Trissolcus basalis (Wollaston). The two parasitized egg clusters had a total of 32 eggs and from them 31 adults of T. basalis emerged. This scelionid was purposely introduced from Australia in 1962 as a biocontrol agent for Nezara viridula. Note presented by Mr. G. Funasaki.

July

The 775th meeting of the Hawaiian Entomological Society was called to order by President A. W. Morrill, Jr. on 13 July 1970, at 2:00 p.m. at Agee Hall, HSPA Experiment Station. Members Present: Balock, Beardsley, Bess, Bianchi, Clagg, Drake, Gagne, Gressitt, Haramoto, Hardy, Holway, Joyce, Leach, Leeper, Look, Manoto, Montgomery, Morrill, Namba, Napompeth, Nishida, Olney, Olson, Ota, Schroeder, Shiroma, Sugerman, and Tenorio. Visitors Present: Mrs. Joaquin Tenorio, graduate student at Uni versity of Hawaii. Unfinished and New Business: President Morrill read letters re ceived from Dr. Martin Sherman thanking the Society for their role in making the 54th Annual Meeting of the Pacific Branch, E.S.A. a success and from Senate President David C. McClung thanking the Society for thanking him for supporting S.B. No. 1566-70—with the letter was a copy of S.B. No. 1566-70 (concerning the introduction of nonindigenous wildlife) sponsored by Senator McClung. President Morrill announced that S.B. No. 1566-70 was signed into law by Governor Burns. Dr. Gressitt announced that Governor Burns had asked for help in selecting the Animal Species Advisory Commission called for in S.B. No 1566-70. Dr. Haramoto read a letter by Dr. Paul Richards (E.S.A.) thanking the Society for a successful Pacific Branch, E.S.A. Meeting and alluding to a 1976 National E.S.A. Meeting in Honolulu. Vol. XXI, No. I, August, 1971 ,5

President Morrill announced that the 12th Pacific Science Congress will be held in Canberra, Australia, August 18—September 3, 1971.

Notes and Exhibitions Homalopoda cristata Howard: This immigrant encyrtid wasp has been present in Hawaii for many years but was previously unidentified. The species was described in 1894 from St. Vincent Island, British West Indies, and has been collected also in Cuba, Trinidad and Ceylon. The oldest Hawaiian specimen was collected by F. X. Williams in 1936. The species has been taken by me on Maui and Oahu. During May, 1970, several specimens were reared from a bark-infesting armored scale, Dup- laspidiotus claviger (Cockerell), on Jasminum stems. This is the first local host record. Hawaiian specimens were determined by me through com parison with type material in the U. S. National Museum, Washington, D. C. Note presented by Dr. J. W. Beardsley. Passaloecus ithacae Krombein: This sphecid wasp of the sub family Pemphredoninae is a new state record. Five specimens, all from Manoa Valley, Honolulu, were found in collections of beginning entomo logy students in June, 1969 and May, 1970. Determination by Dr. Carl Yoshimoto, Canada Dept. of Agriculture, Ottawa. Another Passaloecus, P. luzonensis Rohwer, has been present in Hawaii for many years. These small wasps provision nest cells with aphids. P. ithacae was described from eastern North America. Note presented by Dr. J. W. Beardsley. Gupes clathratus Sobsky: This cupesid beetle was first reported last year by Mr. Jack Fujii, U. of H. Entomology Department. A second specimen, collected at light at Pearl City, Oahu, May 7, 1970, by Mr. Santos, was found by Mr. Howarth in one of the student collections. Note presented by Dr. J. W. Beardsley. Melormenis antillarium (Kinkaldy): This flatid bug was first reported on the basis of a single specimen collected at Hilo, Hawaii, by Mr. Benjamin Hu, in October, 1967 ("Proceeding" 20(2): 264).' A second specimen, collected at Kapapala, Hawaii, 4 April 1970, by Mr.^ G. Smith, was found in a student collection by Dr. Beardsley. Note presented by Dr. J. W. Beardsley. Stylopsized Spehcid Wasp: Mr. N. Matayoshi, a beginning entomology student, collected a female specimen of a sphecid wasp, Chlorion (Isodontia) harrisi Fernald, which bears two females and one empty male puparium of an undertermined strepsipteran protruding between ab dominal tergites. The specimen was taken at Wahiawa, Oahu, 13 March 1970. This is the first record of Strepsiptera attacking C harrisi in Hawaii. It seems likely that this stylopid is not the same as Xenos aurifer Pierce, the species which parasitizes Polistes aurifer in Hawaii, as species of Strepsiptera are generally quite host specific. Note presented by Dr. J. W. Beardsley. Hydroptila arctia Ross: Specimens of the recently discovered im- 16 Proceedings, Hawaiian Entomological Society migrant caddis-fly, previously reported by C. R. Joyce, as Hydroptila sp. ("Proceedings" 20(2): 275), have been determined as H. arctia by B. L. Blickley and D. G. Denning. Larvae of what is probably this species were collected by Dr. Mercedes Delfinado in Opaeula Stream, Oahu, in June. These inhabit small, light tan purse-like silk cases about 3 mm long. Larvae of and cases of another species, apparently Oxyethira maya Denning, also were discovered recently at Honokahua Stream, West Maui, by Dr. John Maciolek. The Oxyethira larvae inhabit transparent whitish cases about 3 mm long which are made of extremely fine silk. These cases are elongate, flattened, and somewhat narrowed at the poste rior end. Note presented by Dr. J. W. Beardsley. Coniocampsa zimmermani Kimmins: Larvae of this tiny neu- ropteran (Family Coniopterygidae) were discovered at Barbers Point, Oahu, on stems of oleander heavily infested with armored scales and mites during May, 1970 by J. W. Beardsley. Adults were reared; these emerged from irregular silk cocoons found in pit galls of Asterolecanium pustulans, and bark crevices. Cocoons were formed of an inner layer of dense cottony silk fibers, and an outer coarse silk meshwork. This is the first report of the finding of the immature stages of coniopterygids in Hawaii. Note presented by Dr. J. W. Beardsley. Megaselia rufipes (Meigen): This cosmopolitan phorid fly was taken on two occasions in Honolulu from mosquito light trap catches at the Public Health Service Quarantine Station. The first specimen was taken on 18 October 1961, and the second one on 2 May 1966. Identifica tion of the specimens were confirmed by Dr. Wirth of the U. S. National Museum. Nothing is known as to its distribution in Hawaii or whether it is established. The species has not previously been reported from Hawaii. M. rufipes is almost worldwide in distribution and is reportedly widespread and very common in Europe and North America. It has been reported to have been involved in cases of wound myiasis. Note presented by Dr. C. R. Joyce. Trox suberosus Fabricius: This determination was received for the Trox sp. which was reported at the February 17, 1970 meeting. Deter mination was made by Dr. R. D. Gordon of the USNM and relayed to me by Dr. F. G. Andrews of Sacramento. This constitutes a new insect record for the state. Note presented by Mr. E. Shiroma. Program: Dr. Henry Bess introduced Dr. Toshiyuki Nishida, Uni versity of Hawaii Entomology Department, who gave a very interesting and stimulating "Discussion on the Concept of Ecology and Pest Manage ment."

August

The 776th meeting of the Hawaiian Entomological Society was called to order by President A. W. Morrill, Jr. on 10 August 1970, at 2:00 p.m. Vol. XXI, No. I, August, 1971 17

at Agee Hall, HSPA Experiment Station. Members Present: Balock, Beardsley, Bess, Chambers, Chang, Davis, Drake, Gagne, Gressitt, Haramoto, Joyce, Kajiwara, Kawamura, Leach, Leeper, Look, Morrill, Nakata, Namba, Napompeth, Nishida, Olson, Shiroma, Sugerman, and Woolford. Visitors Present: Mrs. Ercell C. Woolford, Messrs. Franklin Chang and Manson Valentine. Membership Committee Report: Dr. Frank Haramoto submitted the membership application of Miss Vatana Rungvatana, an East-West Center grantee from Thailand, to the Society for ratification—member ship was ratified. Dr. Haramoto announced that Mr. Herbert Yanamura had officially withdrawn from the Society. Committee on Common Names: Mr. C. J. Davis asked for the cooperation of Society members in revising and bringing up to date the list of common names of Hawaiian insects. The Editorial Committee: Dr. J. W. Beardsley reporting for Dr. Tamashiro advised that the "Proceedings'" manuscripts had been sent to the printer in Japan. Unfinished and New Business: President Morrill read two letters from William W. Allen, Secretary-Treasurer, Pacific Branch, E.S.A.: one to Dr. Namba thanking him for his help in the Pacific Branch, E.S.A. Meeting and acknowledging a $50 contribution to the Woodworth Award Fund; the other addressed to President Morrill thanking the Society for a successful Pacific Branch, E.S.A. Meeting. Cliff Davis announced a drive for membership by the "International Organization for Biological Control (IOBC)"—all those who are interesed in joining the IOBC should get in touch with Mr. Davis.

Notes and Exhibitions

Paraleyrodes perseae (Quaintance): Specimens of this recent immigrant whitefly, first reported from Oahu during 1969, were found on citrus leaves from Kona, Hawaii, sent in by a county agent on 6 August. This is a new island record. The citrus leaves bearing these whiteflies were also infested by the cloudy winged whitefly, Dialeurodes citrifolii (Mor gan) . Although P. perseae has been reported only from Plumeria in Hawaii, it is known to occur on citrus and several other hosts elsewhere. Note presented by Dr. J. W. Beardsley. Parasites of Chrysopidae: Large numbers of green scale Coccus viridis (Green), were collected on Gardenia leaves at Waimanalo during July for rearing and shipment of scale parasites to Texas. Larvae of a green lacewing, Chrysopa basalts walker, were fairly plentiful of scale in fested leaves. Several of these were held for rearing of the adults. Of six cocoons formed, only one yielded an adult C. basalis. Four yielded adults of an encyrtid parasite, Isodromus axillaris Timberlake. No mention 18 Proceedings, Hawaiian Entomological Society of this parasite has been made in our literature since 1935 when it was reared from the same host (then known as Chrysopa microphya McLachlan) by O. H. Swezey (Proceedings 9: 21). One C. basalis cocoon yielded 12 adults of an eulophid parasite, Tetrastichus chrysopae Crawford. This species was found in Hawaii for the first time during 1969 by Mr. Eugene Drake, who reared it from a cocoon of Chrysopa lanta Banks (a synonym of C. comanche Banks). Note presented by Dr. J. W. Beardsley. Pineus pini: This adelgidae reported by George Funasaki at the June Hawaiian Entomological Society meeting as heavily infesting Pinus pinaster trees at Waikii, Hawaii, for a new state record has been found on Japanese black pine, Pinus thunbergii, at a garden shop in Kailua and a nursery at Hawaii Kai, Oahu, for a new host and island record. Note presented by Mr. K. Kawamura. Zootermopsis angusticollis (Hagen): Several nymphs and a soldier of this damp wood termite ((Hodotermitidae) was found in a single Douglas fir lumber by a lumber yard employee in Nawiliwili, Kauai, on 29 June 1970. This species occurs in the Pacific coastal states on the Mainland U. S. It previously was intercepted in Douglas fir lumber in Hilo on 26 February 1965 (Proceedings 20: 135) and in Honolulu on 29 October 1965 (Proceedings 20: 146). Note presented by Mr. K. Kawa mura for Mr. G. Funasaki. Pollenia rudis (Fabricius): Several adults of this calliphorid, commonly referred to as the cluster fly, was collected by D. Sugawa in the Kalalau rain forest on Kauai on 7 July 1970. This is the first record for Kauai. It also has been reported from Oahu and Hawaii. K. Kawa mura for G. Funasaki. Neodusmetia sangwani Rao and Anagyrus antoninae Timber- lake : These two encyrtid wasps emerged in moderate numbers in June 1970 from the Rhodes grass scale, Maskell, which was heavily infesting California grass in Hilo, Hawaii. A single adult of A. antoninae emerged on June 9, 1970, from the Rhodes grass scale on Bermuda grass in Kahului, Maui. N. sangwani formerly was reported only from Oahu and Molokai. A. antoninae was previously reported only from Oahu, Molokai and Lanai. binotatus (Fabricius), Rhinacloa forticornis Reuter, and Xylosandrus compactus Eichhoff: A single teneral male of the plant bug, S. binotatus (det. Gagne), bearing the following data—Ahumoa Crater, Hawaii, 6,500', VI-21-1966, J. W. Beardsley, Sophora—represents a new state record. This European species is considered to be a pest of pasture grasses in North America and New Zealand, particularly in areas saved for seed production (cf. N.Z.J. Agric. Res. 2:15). Thus, the host record should be considered a perching record. Two field trips to this area in November 1968 and July 1970 failed to reveal its presence. It is considered doubtful that it is successfully established. Vol. XXI, No. I, August, 1971 19

R. forticornis is now found on Molokai and Lanai—new island records. Since the first recovery of this plant bug at Honolulu in 1962 (Proceedings 18: 207), it has rapidly become one of the more frequently encountered mirids in all habitats from sea level to tree line. Judging from the habits of its congeners and its lack of host-plant specificity, it is probably pre- daceous on other . The black twig borer, X. compactus (det. Dr. K. E. Schedl from Aus tria), was found attacking mehamehame, Drypetes phyllanthoides (new host record), in the Waianae Mts., Oahu. It was found heavily attacking the sucker-like twigs on these trees. In view of the fact that D. phyllanthoides is among our rarest endemic plants, has incredibly durable wood, and is one of the most magnificent members of our flora, anything further contributing to its debilitation is cause for concern. Notes presented by Mr. W. Gagne.

September

The 777th meeting of the Hawaiian Entomological Society was called to order by President-elect Dr. Derrell L. Chambers on 14 September 1970 at 2:05 p.m. at Agee Hall, HSPA Experiment Station. Dr. Chambers reported the Executive Committee accepted a pro cedural change in the reading of the minutes—henceforth, notes will not be re-read in the minutes. Summary titles of notes will be given in lieu of re-reading notes in their entirety. Members Present: Balock, Beardsley, Bess, Chamber, Chang, Chong, Drake, Haramoto, Hardy, Higa, Howarth, Joyce, Kajiwara, Kawamura, Krauss, LaPlante, Leach, Leeper, Nakata, Namba, Napompeth, Olson, Ota, Pemberton, Shiroma, Sugerman, Tenorio, and Yu. Visitors Present: Mr. John I. Kjagaard, Sawarng Charoenying, Carol Barendregt, and Mrs. Joaquin Tenorio. Membership Committee Report: Dr. Frank Haramoto submitted membership applications for Dr. Edward P. Mumford and Mr. Larry M. Nakahara to the Society for ratification—membership was ratified. Unfinished and New Business: Dr. Chambers announced the fol lowing people have been selected by the Executive Committee to serve on the Nominating Committee: Dr. Frank Radovsky Bishop Museum Dr. Martin Sherman University of Hawaii Dr. Vincent Chang Hawaiian Sugar Planters' Association Mr. George Funasaki Hawaii Department of Agriculture Mr. Ed Shiroma Federal Plant Quarantine (Airport) Presentation of Papers: Mr. Stanley Higa submitted a paper entitled, "Vectors of the Papaya Mosaic in Hawaii" by Stanley Y.

Notes and Exhibitions

Xanthopimpla punctata (Fabricius): An ichneumonid wasp, collected by Mr. Richard Suzukawa at the USDA Fruit Fly Laboratory, University of Hawaii Campus, Honolulu, December 1969, was determined as X. punctata by Dr. R. W. Carlson of the Systematic Entomology Labor atory, U.S.D.A., in Washington, D. C. A second specimen of this species was collected by Mr. Ed Shiroma at Wahiawa, Oahu, about the same date. This is a new insect record for Hawaii. X. punctata is a widely distributed Asiatic species known from Afganistan, through India and Ceylon, China, Indonesia, Malaysia, Mauritius, Philippines, Japan, Ryukus, and Taiwan. It is listed by Nickel (1964. Int. Rice Research Tech. Bui. 2) as a parasite of Chilo supressalis. Townes, Townes, and Gupta (1961. A Catalogue and Reclassification of the Indo-Australian Ichneumonidae) cite references to a number of other host, principally pyralid and tortricid moth borers. Among those listed only Maruca testulalis (the bean pod borer) and Anomis Jlava (F.), a noctuid leaf feeder, are known to occur here, although the parasite probably will be found attacking other species of lepidopterous larvae as well. Note presented by J. W. Beardsley. Pachysomoides stupidus (Cresson): This identification was also received from Dr. Carlson for another new immigrant ichneumonid. This species was first collected here on May 11, 1970, by Mr. G. Smith, a stu dent in General Entomology, on the University of Hawaii Campus in Honolulu. This and a second specimen were found by Dr. Beardsley in student collections. A third specimen was collected alive by Dr. Beardsley on the window of his car in Honolulu. P. stupidus is a New World species known from the southeastern U. S. (Texas, Florida, and the Carolinas) and through Central America, south to Brazil. This ichneumonid de velops as a parasite on the larvae of Polistes wasps. Townes and Townes (1962. U. S. National Museum Bui. 216, Pt 3, p. 399) cite host records of Polistes species of the "canadensis group". The latter includes P. ex- damans, which occurs in Hawaii and seems to be the most likely host here. The biology of a second species, P. fulvus Cresson, which is more widely distributed in North American, has apparently been studied in some detail (see Townes and Townes for references). The wasp deposits its eggs on mature Polistes larvae just before they are ready to spin their co coons. Two to 6 wasp larvae may develop on one host. These feed on the pupa or prepupal larva of the host within the closed host cell. When mature, they spin their cocoons within the host cocoon. Note presented by Dr. J. W. Beardsley. Predators of Psylla uncatoides: On July 22, heavy infestations of the psyllid, P. uncatoides, were observed on young terminal growth of Acacia koa at several localities along the Mauna Loa Strip Road and in Kipuka Ki, Hawaii Volcanoes National Park. Larvae of two predators were observed feeding on psyllid nymphs and adults were reared from Vol. XXI, No. I, August, 1971 21 infested twigs in the laboratory in Honolulu. No predators of P. uncatoides have been reported in Hawaii. The species found were a syrphid fly, obliqua (Say) and a brown lacewing (Family Hemerobiidae), which appears to be an unrecorded immigrant here. This area was visited again on August 28, at which time psyllid populations were much reduced. The principal predators present at the later date were the unknown hemorobiid, and an endemic green lacewing, Anomalochrysa hepatica McLachlan. Larvae of both these neuropterans were reared to adulthood from psyllid-infested koa twigs. Note presented by Dr. J. W. Beardsley. Acerophagus texanus (Howard): This species, previously un recorded from Hawaii has been present here for at least 10 years. There are more than a dozen specimens in local collections. The oldest was collected at Ewa, Oahu, in April, 1960, by J. W. Beardsley. Described originally from Brownsville, Texas, the species occurs also in Mexico (see D. Rosen, 1969. Hilgardia 40(2): 63-66). A. texanus is recorded as a primary parasite of the striped , Ferrisia virgata (Cockerell), but none of the local specimens were reared. All local specimens were taken on Oahu, except one collected at Lanaihale, Lanai, Jan. 1962. Determined by J. W. Beardsley. Note presented by J. W. Beardsley. Ooencyrtus guamensis Fullaway: This species was originally described from Guam (1946. B. P. Bishop Museum Bui. 189: 205). It was first collected in Hawaii on 3 October 1963, by J. W. Beardsley at Waimanalo, Oahu. In December, 1963, a series of 9 specimens were reared from the puparium of an aphidophagous syrphid collected on corn at Waimanalo by J. W. Beardsley. On 24 August 1970, Mr. Banpot Napompeth reared about two dozen specimens from puparia of aphid- feeding syrphids, which he collected on corn at Kaaawa, Oahu. Speci mens were determined by J. W. Beardsley by comparison with types in the USNM, Washington, D. C. The species was described from Guam (B. P. Bishop Mus. Bui. 189, p. 205, 1946) where it was also reared from syrphid puparia on corn. 0. guamensis runs to the genus Ooencyrtus in keys to encyrtid genera; but, on biological evidence, this placement seems questionable, as all other Ooencyrtus species whose habits are known are egg parasites of or . Note presented by Dr. J. W. Beardsley. Atrichopogon jacobsoni (de Meijere). This ceratopogonid was taken in large numbers on windows, coming to lights, at Waianapanapa cabins, Hana, Maui, 2-5 September 1970. This is new island record. Hylephila phylaeus (Drury): Adult specimens of a Hesperiidae were submitted for identification on 8 September 1970, by George Komatsu of the Vector Control Branch, State Dept. of Health. He stated they were flitting about and probably ovipositing of his Bermudagrass lawn in the Salt Lake area of Honolulu and that he first noticed the adults 22 Proceedings, Hawaiian Entomological Society about a month ago. A survey in the Salt Lake area on September 9, 1970, revealed numerous adults at large and on Bermudagrass. This is the first species of Hesperiidae to have gained entry into Hawaii. The species is tentatively identified by G. Funasaki as the fiery skipper, Hylephila phylaeus (Drury), which is a pest of grasses in much of the southern states on the mainland. Specimens were submitted to the USNM and a posi tive identification will be reported at the next meeting. Presented by Mr. K. Kawamura for Mr. G. Funasaki. Formicomus imperator (LaFerte): Seven specimens collected on February 19, 1968, in soil at the Honolulu International Airport grounds by George Funasaki were confirmed as this species by Floyd Werner, University of Arizona, Tucson, Arizona. Distribution includes Micro nesia, India, and Japan; and, it is apparently a micro-scavenger. (Chapin, Werner—Insects of Micronesia, Vol. 16, No. 5—B. P. Bishop Museum, 1965. pp 255-269.) indomita and umbricola: A random survey of monkey pod trees throughout Oahu revealed larvae of both Polydesma umbricola and Melipotis indomita under loose bark. M. indomita was first found on Oahu in June, 1969; larvae have been subsequently found under loose bark of kiawe and adults in areas of dense Desmanthus growth. This is the first report of its activity on monkey pod; larval specimens brought back to the laboratory fed readily on its foliage. Ap proximate percentage to date of both species collected at random; Oahu- 60% M. indomita, 40% P. umbricola; Maui-87% M. indomita, 13% P. umbricola; Kauai-95% M. indomita, 5% P. umbricola. It now appears that the new immigrant pest is the major cause of unusually heavy defoliation of monkey pod trees this year. Note presented by Mr. K. Kawamura. Bakerpolipus serratus Husband and Sinha: Specimens of this recently described mite (Ann. Ent. Soc. 63(4): 1148-1152) were first observed in June, 1967, parasitizing Nauphoeta cinerea (Olivier) (Orthoptera: Blaberidae) cultured in the laboratory at the University of Hawaii in Honolulu. On 22 February 1970, this species of mite was observed on more than 80 percent of the adults but none on the nymphs of N. cinerea collected from a warehouse containing cattle feed in Honolulu. Two adults of the Surinam cockroach, Pycnoscelus surinamensis (L.), collected on the same date and from the same habitat as that of N. cinerea were also parasitized by B. seratus. Colonies of B. serratus were most frequently encountered beneath the wings near their bases, however, on heavily infested cockroaches, clusters of B. serratus occurred on the intersegmental membranes of all parts of the thorax. Note presented by Dr. F. H. Haramoto. 'Program: Dr. Henry Bess introduced Mr. Noel L. H. Krauss, who gave an interesting travelogue of his excursions through Alaska, Canada, and Oregon.

Hemerobius pacificus Banks: At the September meeting I re ported collecting adults and larvae of an unknown brown lacewing (Hemerobiidae) in association with infestations of the acacia psyllid on koa trees in Hawaii Volcanoes National Park. Apparently this lacewing is Hemerobius pacificus, a species which is widely distributed on the West Coast of North America. The presence of H. pacificus in Hawaii was reported in 1964 by Dr. Ellis MacLeod. He collected two specimens at the Kilauea Military Camp on 16 October 1948. The record was pub- 24 Proceedings, Hawaiian Entomological Society

lished in Pacific Insects (Vol. 6(1): 1-4), but no record of this insect has appeared in our "Proceedings". Recently collected specimens have been sent to Dr. MacLeod for verification. Note presented by Dr. J. W. Beardsley. Pachysomoides stupidus (Cusson): During the past month, two abandoned nests of Polistes exclamans exclamans Viereck were collected in Honolulu. These nests exhibit evidence of parasitism believed to have been caused by P. stupidus. Many of the Polistes larval cells contain from one to six empty parasite cocoons, and exhibit small circular exit holes cut through the cell walls. P. stupidus is a known Polistes parasite but has not been reared in Hawaii. I have been unable to locate a viable Polistes exclamans nest to confirm this suspected parasitism." Apterocyclus honoluluensis Waterhouse: No additions to the Bishop Museum's collections of the Kauaian endemic lucanid, A. hono luluensis (Gagne det. & col.) appear to have been made within the last 45 years. A single male was collected at night walking on the forestry road along Milolii Ridge, Kokee State Park, 1060 m, in August, 1970. Note by Mr. W. Gagne. Goptops aedificator (F.): The immigrant cerambycid, C. aedificator (det. Davis), was reared 30 June from a limb of the endemic ohe makai tree, Reynoldsis sandwicensis, from Niu Valley, 100 m, 6 June 1970, W. Gagne. Judging from Duffy's paper (P.H.E.S. 15: 155), this appears to be a new host record. Note by Mr. W. Gagne. Halticus chrysolepsis Kirkaldy: The grass fleahopper (det. Gagne), a probable immigrant mirid, is known at present only from Oahu. Specimens have been uncovered in unsorted material at the Bishop Mu seum, which extends its distribution to three other islands: Molokai, Manawainui Gulch, VII-1952, M. Tamashiro; Hawaii, Kona Dist., Puu Waawaa, 22-111-1961, S. Quate; and Kauai, Kokee, 4-VIII-1961, Maa, Miyatake, and Yoshimoto. Note by Mr. W. Gagne. Jadera haematoloma (H. & S.): The rhopalid bug, J. haematoloma (Gagne det. & col.), was found feeding on the epicarp of the seeds of the endemic lonomea tree, Sapindus oahuensis, in Haeleele Valley, Kauai, 450 m, 5-IX-1970. Adults and nymphs were abundant on the trees and on fallen seeds in the leaf litter. They feed only on the epicarp, leaving the kernel undamaged. This is a new host record. Both the bug and its potential host are present on Oahu; but, its association here, other than with Balloon vine, has not yet been observed. In January 1970, large numbers were observed on fruits and seeds of the golden-rain tree, Koelreuteria formosana, at Kona, Hawaii. Note by Mr. W. Gagne. Lygus elisus Van Duzee: The pale legume bug (Gagne det. & col.), was found breeding on an exotic Chenopodium at Barbers Point, Oahu, in May, 1970. This serious pest of alfalfa and other crops in the western U. S. still seems to remain innocuous in the state since its first recovery Vol. XXI, No. I, August, 1971 25 in 1947. Note by Mr. W. Gagne. Oncocephalus pacificus Kirkaldy: Another human biting record of the newly immigrant assassin bug, 0. pacificus (det. Gagne), has been uncovered, this one from Radford Terrace, Oahu, 1 l-VIII-1970, by J. R. Bridges. The collector said that the bug was biting a woman on the arm and that he had seen two other specimens near his home. The bug very superficially resembles the red-margined kissing bug, Triatoma rubrofasciata (De Geer), but is little more than three-quarters the length of the latter and is light brown with darker fasciae and striations on the hemelytra and pronotum. It is probably a general insect predator as it is a member of the Stenopodinae, rather than the notorious Triatominae; but, many assassin bugs are quick to bite when slapped or grasped. Note by Mr. W. Gagne. Polididus armatissimus Stal: Adults of the spiny assassin bug were collected at porch lights at Kapaa and Kipu, Kauai, in August, 1970, and adults and nymphs by sweeping ferns at night along the Kaulale- walewe-Puu Trail, W. Maui, 915 m, 17-11-1970 (Gagne det. & col.). This represents a new record from Maui and its second record from Kauai (P.H.E.S. 20: 20). Note by Mr. W. Gagne. Psylla uncatoides (Ferris & Klyver): Adults of the acacia psyllid were found in great numbers at the summit of Mauna Kea, Hawaii, both on the walls of the new observatory and washed up in shore debris at Lake Waiau, 28-VII-1970 (Gagne det. & col.). This is apparently a reflection of its tremendous infestation on koa at lower elevations. Note by Mr. W. Gagne. Hylephila phyleus (Drury): The Hesperidae reported at last month's meeting has been confirmed as Hylephila phyleus (Drury) by W. Bauer, California Dept. of Agriculture, and by W. D. Field, USNM. Note by Mr. G. Funasaki. Opius importatus Fischer: A previously undescribed Opius was named Opius importatus by Dr. Max Fischer of the National History Museum in Vienna, Austria. Opius importatus Fischer and another braconid, Opius phaseoli Fischer, are commonly found attacking the bean fly, Mel- anagromyza phaseoli (Tryon), here in Hawaii. They were purposely intro duced by the State Dept. of Agriculture from East Africa in April, 1969, to aid in the control of the bean fly. The following differences, provided by Dr. Fischer, may be used to identify the two species: Propodeum rugose, precoxal suture crenulate or rugose Opius importatus Propodeum smooth and shining, precoxal suture of Mesepisternum without sculpture Opius phaseoli Opius phaseoli and Opius importatus were previously referred to as 26 Proceedings, Hawaiian Entomological Society

Opius melanagromyzae Fischer and Opius sp., respectively (Haw'n. Ent. Soc. Mtg., Jan. 20, 1970). Note presented by Mr. G. Funasaki. Musca sorbens Weid.: Four specimens of this pestiferous fly were collected from three areas on the Island of Molokai on 25 Sept. 1970. One female from a residence in Kaneololoa; two females from a residence in Kaunakakai; and one male were collected from another residence in Kaunakakai. These collections were made by Mr. W. Watanabe, Entomologist, Vector Control Branch, State Health Department. Twelve specimens of M. sorbens were collected on the Island of Maui on 23-24 Sept. 1970. One male was collected from the feedlots in Olowalu; three females and one male from a residence in Waikapu; three females and two males from a residence in Kihei; and two females were collected from a residence in Napili. The specimens were collected by Mr. W. Watanabe and the resident personnel (Messrs. W. Garcia and J. Duarte) on the Island of Maui, Vector Control Branch, State Health Department. Five specimens (four females and one male) of Musca sorbens Weid. were collected near a piggery in Kealakekua, Kona on 6 Sept. 1970 by Mr. W. Watanabe and the resident personnel (Masato Kobatake) on the Island of Hawaii, Vector Control Branch, State Health Department." Note presented by Mr. J. Ikeda. Pollenia rudis (Fabricius): In the B. P. Bishop Museum collec tion are two early collections of the cluster fly, Pollenia rudis, taken at Kokee, Kauai. The collection data are: Kokee, Kauai, 27 July 1959, banana bait trap, J. W. Beardsley, 7 specimens, and Kokee, Kauai, 4-6 Aug. 1961, Maa, Miyatake and Yoshimoto, 26 specimens. Nine of these specimens were determined by Maurice T. James in 1962. The large number of specimens indicates that this species was established on Kauai at that time. Since these collections apparently predate the infestation on the Island of Hawaii, this record is of considerable interest." Note presented by Mr. F. G. Howarth. Trogoderma variabile Ballion: Thirty larvae of T. variabile were taken from a trogotrap located in the Shigetomi Feed Store at 1827 S. Beretania St. in Honolulu on 16 September 1970. The trogotraps are used for khapra beetle detection. Identification was made by C. J. Hansel of the Insect Idertification Branch, U.S.D.A., in Beltsville, Maryland. T. variabile was intercepted in pig feed from Oregon in October, 1968. Twenty-two dermestid larvae taken from a trogotrap in the 50th State Dairy Farmers Coop, on 14 May 1970, were determined by C. J. Hansel as Dermestidae—Trogoderma possibly variabile Ballion. Program: Dr. Bess introduced Dr. Franklin Chang, University of Hawaii, who gave an interesting presentation on the source of energy for insect flight. Vol. XXI, No. I, August, 1971 27

November

The 779th meeting of the Hawaiian Entomological Society was called to order by President A. W. Morrill, Jr., on 9 November 1970, at 2:03 p.m. at Agee Hall, HSPA Experiment Station. President Morrill asked the members to rise and observe a moment of silence in memory of Dr. R. H. Van Zwalenburg who passed away. Members Present: Balock, Beardsley, Chambers, Chang, Davis, Drake, Funasaki, Gagne, Gressitt, Haramoto, Howarth, Joyce, Madinger, Montgomery, Napompeth, Olson, Shiroma, Sugerman, and Woolford. Visitor: Mrs. H. A. Woolford. Liaison Committee Report: W. C. Gagne reported that an article he had written on conservation appeared in the Honolulu Advertiser. Common Names Committee Report: C. J. Davis reported he had sent out letters to the Committee members and will meet soon to update common names of insects in Hawaii. Ad Hoc Committee for Annual Dinner Meeting: Bernard Sugerman reported that the Annual (December) Dinner Meeting would be held at the Tripler Hospital Officers Club. President Morrill announced that he would send letters of condolence to Mrs. Van Zwalenburg and Wally A. Steffan.

Notes and Exhibitions Ooencyrtus guamensis Fullaway: On 25 September 1970 Dr. Frank Haramoto collected 24 specimens of an aphidophagous syrphid, mature larvae and puparia, from aphid-infested corn at Waimanalo, Oahu. This material yielded nine adult flies which were determined as Allograpta exotica (Wiedemann) by Dr. D. E. Hardy. Of the remaining puparia, 12 were parasitized by Ooencyrtus guamensis, and 4 were dead but apparently unparasitized. A total of 182 parasites emerged from 12 puparia (an average of 15 parasites per puparium). Parasite emergence from four puparia isolated individually ranged from 12 to 20. Both sexes of the parasite emerged from each of these puparia, with females predominating in each case. The pooled sex ratio was 3.5 $$: 1 (J. Note presented by Dr. J. W. Beardsley. Liris labriosa (Smith): This determination was received from Dr. A. S. Menke, Systematic Entomology Laboratory, USDA, Washington, for a specimen of a sphecid wasp collected on Oahu. This is a new state record for the State. L. laboriosa belongs to subfamily Larinae, a group which provisions nests with paralyzed crickets. The species was described from the Philippine Islands. Krombein (1949, Proc. Hawaiian Entomol. Soc. 13: 395) states that it is a widely distributed Oriental species, and lists it from several localities in the Mariana Islands. L. laboriosa resembles L. subtesselata (Smith), which has been present in Hawaii for many years, 28 Proceedings, Hawaiian Entomological Society

but is somewhat larger with wings more strongly infumated with yellow. Both these species were placed in the genus Motes in Krombein's 1949 paper on Micronesian Aculeate , but Dr. Menke indicates that these species are now placed in the genus Liris. L. laborosa apparently has been present in Hawaii for at least seven years. Eight female speci mens were found in the University of Hawaii collection, the oldest collected 14 October 1963 by Pam Howell. Dr. Menke states that the USNM collection contains a single specimen collected by E. Shiroma, 15 Sep tember 1963, in Honolulu. Note presented by Dr. J. W. Beardsley. Megastigmus sp.: A lot of Christmas berry fruit was collected in Honolulu during September and held in the laboratory in hopes of obtaining adults of the introduced seed weevil, Bruchus atronotatus Pic. Instead of yielding weevils, the seeds produced numerous adults of a chalcid wasp belonging to the family Torymidae. Larvae of this group are phytophagous, infesting seeds of many different plants. The species reared has been reported previously from Oahu as Megastigmus sp., but up until now its seed host was unknown. Note presented by Dr. J. W. Beardsley. Melormenis antillarum (Kirkaldy): A specimen of this immi grant flatid bug was collected by J. W. Beardsley at his home in Aina Haina, Honolulu, on 15 September 1970. This is the third time this species has been collected in the State, and the first record from Oahu. M. antillarum was first taken in Hawaii in October, 1967, in Hilo, by Mr. Benjamin Hu. A second specimen, also from the Big Island, was re ported earlier this year. Determination was made by Dr. J. P. Kramer, U. S. National Museum, Washington, D. C. Note presented by Dr. J. W. Beardsley. Ghrysolina quadrigemina (Suffrian) (Klamath weed beetle): The Klamath weed beetle, C. quadrigemina released on perforatum near Poikahi, Mt. Hualalai in June, 1965 was found on H. degeneri, a new host species record at a sawmill site in the vicinity of the Puu Oo Trail, Kilauea Forest Reserve on 15 Sept. 1970 at an elevation of 1,676 m. This is approximately 60 miles from the Mt. Hualalai release point. It was subsequently found at the edge of the forest contiguous to the Uni versity of Hawaii Experiment Station, Wright Road, on 12 October 1970 and at the International Biological Program Weather Station, Bishop Estate, 1,645 m on 19 October 1970. Eggs, larvae and adults were readily found at the latter site. One adult was found near I.B.P. headquarters, National Park residen tial area, indicating that this purposely introduced chrysomelid is well distributed in the Kiluea region. At the present time the population density of this beetle appears much greater on H. degeneri than on H. perforatum at Mt. Hualalai. Note presented by Mr. Cliff Davis. Vol. XXI, No. I, August, 1971 29

Lachnus salignus: Heavy populations of the aphid, Lachnus salignus, were observed on pussy , Salix sp., in the Volcano District, Hawaii, on 12 October 1970. Pussy willow is a new Hawaiian host record for the largest aphid we have in Hawaii. Alates were very abundant on leaves while apterous forms were abundant on the twigs. Note presented by Mr. C. J. Davis. Apanteles militaris (Walsh): Cocoons of A. militaris were found in the vicinity of the Puu Oo Trail, Bishop Estate, on 27 October 1970. This is the first record of this effective cosmopolitan armyworm parasite in the Kilauea region and marks a spread of approximately 70 miles from its original release point on the Parker Ranch. Note presented by Mr. C. J. Davis for Mr. F. Bianchi. Coccidoxenus mexicanus (Girault): The first recovery of Coc- cidoxenus mexicanus (Girault), an encyrtid wasp, was made during October, 1970. Light numbers emerged from the barnacle scale, Ceroplasles cir- ripediformis Comstock, collected by Kenneth Kawamura from fiddlewood trees in the Hawaii Kai area on Oahu and from passion fruit at Kahului, Maui. This parasite was purposely introduced from Trinidad, West Indies, in June, 1967 to aid in the control of soft scales in the genera Cero- plastes and Saissetia. Program: President Morrill introduced Wayne C. Gagne, of the Bishop Museum, who gave an interesting presentation on the "Evolution ary Ecology of Hawaiian Mirids."

December

The 780th meeting—the Annual (December) Dinner Meeting—was called to order by President A. W. Morrill, Jr., on 17 December 1970, at 8:13 p.m. at Tripler Hospital Officers' Club. By unanimous consent, the reading of the minutes was waived. President Morrill expressed thanks to the Entertainment Committee for their efforts in arranging the dinner meeting and to the Executive Committee for their participation during his tenure of office. He also noted that two Honorary members were present: Messrs. J. W. Balock and S. Sakimura. Members Present: Balock, Beardsley, Bess, Chang, Chambers, Davis, Gressitt, Haramoto, Hardy, Holway, Howarth, Jackson, Kajiwara, Kaya, LaPlante, Look, Madinger, Morrill, Namba, Nishida, Olson, Radovsky, Raros, Sakimura, Sherman, Shiroma, Sugerman, and Tamashiro.

Reports of Officers and Committees: Executive Committee Report— President Morrill announced that a letter had been sent to Governor Burns asking him to name the commission members for the Natural Area Reserves System recently passed into law. Dr. Gressitt and Hardy and Mr. S. Montgomery were selected by the Governor to serve on the com mittee. President Morrill announced that the Executive Committee completed and returned a questionnaire on the scope and objectives of the Society received from the Oahu Chapter of the Conservation Council for Hawaii. The Oahu Chapter is preparing a comprehensive directory of enviorn- mental action resources in Hawaii which will be published by the Hawaii Environmental Action Registor (HEAR). Presentation of Papers: Dr. J. L. Gressitt submitted a paper on "New Cerambycid Species from Molokai and Hawaii", authored by him self and C. J. Davis. Dr. J. W. Beardsley submitted a paper on "New Genera and Species of Hawaiian Pseudococcidae." Mr. C. J. Davis submitted a paper on "Recent Introductions for Biological Control in Hawaii XVI." Presidential Address: President Morrill introduced and turned the gavel over to incoming President, Dr. Derrell L. Chambers, who intro duced A. W. Morrill for presentation of the Presidential Address. Announcement and Introduction of Newly Elected Officers: Fol lowing the Presidential Address, Dr. Namba introduced to the group the Society officers for 1971: President: Dr. Derrell L. Chambers President-elect: Mr. William C. Look Advisor: Miss Setsuko Nakata Secretary: Mr. Frank J. Olson Treasurer: Dr. Frank H. Haramoto Dr. Namba acknowledged the efforts of Bernard Sugerman in ob taining the dinner meeting site and Dr. Frank Haramoto for taking care of the financial arrangements. The meeting was re-convened by outgoing President A. W. Morrill, Jr., who asked for a motion to accept the Financial Report of the Treasurer, 8 December 1969 to 17 December 1970, submitted by Dr. Frank H. Hara moto. It was so moved, seconded and accepted.

Reyer EL Van Zwaluwenburg 1891-1970

Mr. Reyer H. Van Zwaluwenburg, affectionately known as "Van" to his many friends, died in Honolulu on October 22, 1970, at the age of 79. He had been in failing health since 1968. Much of Van's professional life was devoted to Hawaiian entomology. Except for a period of about four years (1958 to 1962) when he resided in retirement in Santa Rosa, California, Van lived with his family in Hawaii since 1924. For many years he was an active and respected member of this Society, giving generously of his time and talents. Van did much to develop the fine reputation that our Society and its "Pro ceedings" enjoy today. In addition to contributing many papers and notes, he served as editor of this journal for 11 years, from 1944 through 1954. He was President of the Society in 1927, and served several years in the demanding office of Secretary-Treasurer. Upon his retirement in 1956 he was elected to honorary membership. Few others have served the Society so devotedly as did Van. Even after retirement he maintained an active interest in Hawaiian entomology. Although during recent years failing eyesight and poor health forced him to curtail his taxonomic studies, he continued to attend the Society's meetings whenever he was able. In 1965 the Fernald Club Yearbook, organ of the University of Mas sachusetts Entomology Club, was dedicated to Van. This volume contains a biographical sketch and bibliography. From it we learn that Van was born in Kansas City, Missouri, on February 5, 1891. His father was a chemist in the mining industry. Van entered Massachusetts Agricul- 130 Proceedings, Hawaiian Entomological Society

tural College in 1909 and graduated with the Class of 1913. Following graduation he became an entomologist with the Puerto Rico Agricultural Experiment Station at Mayaguez where he worked mainly with pests of coffee and small crops. In June 1916 he married Mary Alice Pattyson whom he met in Puerto Rico. In December 1917, he was transferred to a field station of the Cereal and Forage Insects Branch of the old U. S. Bureau of Entomology at Hagerstown, Maryland, where he concentrated on the biology and control of wireworms. It was there that he developed his lifelong interest in the Elateridae; an interest which resulted in the publication of many excellent papers dealing with the of this important family of beetles. In 1921 Van and his wife moved to Mexico where he became an entomologist for the United Sugar Companies of Los Mochis, in Sinaloa. From that time on Van's professional activities were devoted in large part to the study and control of insects affecting sugarcane. In Mexico he was concerned chiefly with the moth borers, Chilo loftini Dyar and Diatraea (Zeadiatraea) grandiosella Dyar. Much of this work centered on studies of parasites of these pests and attempts to introduce biological control agents into the Los Mochis area. Toward this end, he conducted parasite exploration work in Cuba and various parts of Mexico. Van came to Hawaii in 1924 as Assistant Entomologist with the Hawaiian Sugar Planters' Association Experiment Station, and remained with the "Station" until he retired as Principal Entomologist in 1956. One of his first projects in Hawaii was a detailed faunistic survey and ecological study of the soil invertebrates found in Hawaiian sugarcane fields. A summary of this carefully executed and very valuable research was published as a chapter in the book, "Insects and Other Invertebrates of Hawaiian Sugar Cane Fields," by F. X. Williams. In 1928 Van published his paper on "The Interrelationships of Insects and Roundworms" (Bull. 20, Entomological Series; Experiment Station HSPA, Honolulu). This work is an excellent and exhaustive summary of all that was then known about this subject, and is a fine example of the thoroughness and competence characteristic of all his work. It is still in demand as a standard reference work for insect pathologists and other biologists interested in insect-associated nematodes. In 1929 Van attended the Fourth Pacific Science Congress in Java, following which he spent a summer in Japan collecting and shipping numbers of a tachinid parasite of scarab beetles for trial against Adoretus sinicus in Hawaii. In 1935 he went to West Africa to search for parasites of the Mediterranean fruit fly, several of which were discovered and shipped in numbers to Honolulu. During the summers of 1940 and 1941 Van spent about 12 weeks on Canton Island where he made insect and plant surveys and, in cooperation with Pan American Airways, carried out Vol. XXI, No. I, August, 1971 131 inspection and spraying of aircraft bound for Honolulu. In 1947, while on leave from the HSPA, Van served as entomologist on a team of agri cultural scientists which surveyed the Mexican sugar industry for the Bank of Mexico. In 1956, following his retirement, Van was the recipient of a grant from the National Science Foundation for the study of the types of Pacific Elateridae housed in European museums. In the course of this research he visited museums in London, Oxford, Brussels, Leiden, Amsterdam, Copenhagen, Stockholm, Genoa, and Paris, making detailed notes and photographs of the many type specimens which he was able to locate. The results of this study were published in a 1959 paper in "Pacific In sects," and his photographs and notes are preserved in the Bishop Mu seum. Van was a member of numerous local and national scientific societies and was renowned throughout the entomological world as an authority on elaterid taxonomy. In addition to our own Society, he was a member of the American Association for the Advancement of Science, Entomolo gical Society of America, Hawaiian Academy of Science, California Academy of Sciences, Hawaiian Sugar Technologists, Society of Sigma Xi, Phi Kappa Phi, and the Cosmos Club. He is survived by his wife, their only son, Paul, and three grandchildren, all of whom reside in Hono lulu. Van was one of the kindest, most gentlemanly persons whom the writer has been privileged to know. Always patient, courteous and helpful, he gave unselfishly of his time and experience to aid colleagues and students. There are many who will miss him.
