Brackydeutera ibari Ninomiya: This ephydrid was reported as a new immigrant in Hawaii in 1985 (Evenhuis, PHES. 27:4 and Hardy PHES. 27:7). The species has a widespread distribution as follows: Canary Is lands in the west, eastward through countries of the Mediterranean, Middle East (Egypt, Israel, Iran, Iraq) and China to Japan, Korea, Taiwan and the Hawaiian Islands. D. E. Hardy. Limonia (Dicranomyia) hardyana Beyers: (1985, Intern. J. Entomol. 27(3): 239). This new flightless crane fly was described by Beyers from specimens collected in several places on or near the summit of the Koolau Mts., Oahu by W. D. Perreira, VV. C. Gagne, and S. L. Montgomery. D. E. Hardy. New Island Records: Eumegastigmus (Megastigmus) sp.: Specimens of this wasp (Hymenoptera: Torymidae) were collected from Christmas-berry, (Schinus terebinthifolius Raddi), at Waiohinu, Kau, on the Island of Hawaii on Oct. 24, 1985 by E. Yoshioka. Identification was made by B. Kumashiro. This is a new island record. This wasp was previously found on Oahu in 1970 (PHES, 1971, Vol. 21:28). The species feeds on Christmas-berry seeds. Ckrysobothris sp. nr. tristis Deyrolle: One specimen of this (Coleoptera: Buprestidae) was collected from airport light trap material from Kahului, Maui on Nov. 7, 1985 by P. Conant and C. Kawauchi. Identification was made by B. Kumashiro. This is a new island record. The species was first collected on Oahu in 1946 (PHES, 1949, Vol. 13:341). Diadegma pattoni (Ashmead): Adult specimens of this wasp (Hymenoptera: Ichneumonidae) were reared from the grass webworm {Herpetogramma licarsisalis (Walker)) larvae collected at Hilo, Hawaii in Oct. 1985 by S. Matayoshi. Identification was made by J. W. Beardsley. This represents both new island and new host records. The species was first collected on Maui (1973) and Oahu (1975). The host relationship of this species in Hawaii was previously unknown (PHES, 1977, Vol. 22:403). R. Heu.

FEBRUARY

The 962nd meeting of the Hawaiian Entomological Society was called to order at 2:00 p.m. on February 10, 1986 at the Manoa Library. Twenty-five members and one guest, Lyn Frandsen (EPA Region 10, Seattle) were in attendance. Vol. 28, May 31,1988 3

Program: Franklin Chang of the Entomology Dept. Univ. of Hawaii spoke on "The Development of Anti-juvenile Hormone Compounds as Potential Chemosterilants Against the Mediterranean Fruit Fly". Reports of Officers and Committees: Treasurer: The financial report for 1985 and the dues notices for 1986 have been sent out.

House Bill 2281 would amend Chapter 343 of the Hawaii Revised Statutes to require environmental impact assessment for any organism proposed for importation. House Bill 2287 would establish a Department of Environment that would consolidate some DOA and Health Dept. functions. The proposed department would have four branches: 1. Ground water monitoring, 2. Air quality monitoring, 3. A laboratory division, and 4. an administrative service division. Announcements: Bruce Tabashnik announced a U. of H. Entomol ogy Department Seminar to be held on Feb. 14, 1986: Douglas Dahlman, Entomology Dept. Univ. of Kentucky on "Insect — Plant Biochemical Detante". New Business: Po-Yung Lai has made committee appointments for 1986. Persons serving on committees will receive a roster of committee assignments. Others who wish to receive a roster should request one.

Systena blanda Melsheimer: This immigrant North American palestriped flea beetle (Chrysomelidae: Alticinae) appeared to be well established at Maile, Oahu when it was first collected on Walter Konishi's farm. Those specimens were collected by Pat Conant and W. Kobayashi in May 1983 and by S. Joseph in July 1983; all records were from spiny amaranth. This beetle was also noted on basil (K. Konishi, pers. com- munic), but it was not observed on it when Eric H. Smith and I visited the Konishi Farm on June 24,1985. We collected a large series of blanda on seedling soy bean plants (over 70 specimens in my series); it was also taken in fair numbers on cowpea plants with badly scarred leaves; and a few specimens were taken from various weeds, including spiny amaranth. As predicted by K. Konishi, the beetle became more abundant as the morn ing progressed, from ca. 1030 to 1230 hrs. I tentatively identified this species as Systena blanda in 1983, awaiting confirmation by E. H. Smith. The Maile specimens have the "subapical notch" of the aedeagus that is characteristic of blanda; however, the 4 Proceedings, Hawaiian Entomological Society specimens tended to be slightly longer than usual in body length. It is confirmed by Smith as blanda. In the meantime, R. E. White of the USNM identified this as blanda in 1985. Systena blanda is common and widespread in the continental United States, but little has been published on its host preferences. Balsbaugh & Hays (1972: 167) cited Ambrosia sp. Smith (1986) is expected to give a complete list of host records. References: Balsbaugh, E. U. & K. L. Hays, 1972. The leaf beetles of Alabama (Coleoptera: Chrysomelidae). Auburn Univ. Agric. Exp. Bull. No. 441,223 p. Smith, E. H., 1986. G. A. Samuel- son. Bephratelloides (=Bephrata) cubensis (Ashmead): Specimens of this wasp (Hymenoptera: Eurytomidae) were found infesting seeds of sugar apple (Annona squamosa) fruit collected at a residence in the Kahala district of Honolulu on January 24, 1986 by K. Murai and S. Benzon. Identification was made by J. W. Beardsley, U. H. Entomology Dept., and confirmed by E. E. Grissell of the USDA's Systematic Entomology labora tory. This is a new state record. The larva of this wasp feeds within a seed of the fruit. After pupation, the adult chews its way out of the seed and causes injury by tunneling to the fruit surface. Damage is indicated by emergence holes on the surface of the fruit. Literature indicates that this species occurs in the West Indies, Florida, Mexico, Central and South America and attacks various species of Annona. Several trees within 80 yards of each other contained fruit with identical damage. The homeow ners indicate that damage has occurred for several years. R. Heu. Conchaspis angraeci (Cockerell): Specimens of this scale were col lected from papaya (Carica papaya) in Kaneohe, Oahu in December 1985 and identified as Conchaspis angraeci (Cockerell) by D. M. Tsuda, U. H. Entomology Dept. Specimens of this scale were also collected from sea grape (Coccoloba uvifera) in the Honolulu harbor area of Oahu on Jan. 31, 1986 by K. Teramoto, L. Nakahara, and R. Heu. Identification was made by B. Kumashiro, Hawaii Dept. of Agriculture. Papaya and sea grape are new host records for Hawaii. R. Heu. Helionothrips errans (Williams) 1916: Fifteen females of this thrips (Thysanoptera: Thripidae: Panchaetothripinae) were recovered by Ar nold Hara, Univ. of Hawaii on Dec. 20,1985 from leaves ofCymbidium sp. growing in a commercial greenhouse in Glenwood, Hawaii (elev. 2700')- Tentative identification of this Panchaetothripin was made by myself, and later confirmed by Mr. Kanjyo Sakimura. This constitutes a new state record. Distribution includes Africa, where it has been collected from coffee leaves; and Taiwan, Japan, and England, where it attacks orchids grown in glasshouses. D. M. Tsuda. Echinothrips amerkanus Morgan 1913: On August 8, 1984, a total of 14 adults of this thrips (Thysanoptera: Thripidae: Thripinae: Sericothri- pini) were collected from Impatiens leaves submitted by a Manoa resident to the Pest Diagnostic Clinic, Univ. of Hawaii. Tentative identification of this thrips was made by myself, and later confirmed by Mr. Kanjyo Vol. 28, May 31,1988 5

Sakimura. This constitutes a new host and island record. It was first collected on July 15, 1981 on leaves of BunlongTaro growing in the shade house at the Univ. of Hawaii Waiakea Research Station, Hawaii. Accord ing to Mr. Sakimura this species prefers to feed on various herbs or shrubs located in cool, moist, shady areas. D. M. Tsuda.

MARCH

The 963rd meeting of the Hawaiian Entomological Society was held at 2 p.m. March 10, 1986 at the Manoa Library. Twenty-three members and 5 guests were in attendance. The guests present were: Susan McCombs (U.H.), Linden Teramoto (U.H.), Mike Rethwisch (U.H.), Nita Post- lethwait (U. Oregon), and John Postlethwait (U. Oregon). Program: John Postlethwait of the University of Oregon spoke on: "Sex and Reproduction: Why Don't Males Make Egg Yolk?". Report of Officers and Committees: Treasurer: Stan Higa reported that there has been a good re sponse to the dues statements that were sent out in January. Membership: Two staff members of the Koronivia Research Sta tion, Fiji, Satya Ram Singh and Moti Lai Autar, were nominated for membership and were unanimously voted into the Society. Liaison: Po-Yung Lai reported on the progress of the 2 bills that were discussed during the last meeting. Both House Bill 2281 and 2287 have not been reported out of Committee. Consequently, neither bill has much chance of approval during the current legislative year. Program: Marshall Johnson proposed that the program at one of the summer meetings be a debate on the proposal to require an Environ mental Impact Statement for the introduction of biocontrol organisms. Old Business: Po-Yung Lai — It has been some time since any of the retired members have been accorded Honorary Membership. The Constitution requires that a person eligible for Honorary Mem bership be proposed to the Executive Committee by another member in good standing. Approval by a majority of the Executive Committee will constitute nomination, subject to election by the membership by a % vote by mail ballot. Members are encouraged to propose other deserving members for Honorary Membership. The next mailing will include a list of the current Honorary Members so that others will know who may be eligible for this distinction.

5. Verbesiana encelioides 7. Coronopus didymus 6. Malva coromandeliana Also, Dialeurodes citrifolii (Morgan) was collected from Syngonium sp., which is a new host plant record. All life stages of both species were observed by Greg Paulson at the Maui Experiment Station on March 6, 1986. G. Paulson.

APRIL

The 964th Meeting of the Hawaiian Entomological Society was called to order by Po-Yung Lai at 2 p.m. April 14, 1986 at the Manoa Library. Twenty-one members were present. Three guests also attended: Susan Opp (U. Mass. — Amherst), Steven Tarn (Hawaiian Evolutionary Biology Project), and Ratana Pomaracorn (U.H.). Program: Susan Opp (University of Massachusetts — Amherst) spoke on "The Polygamous Mating System of a Tephritid Fly, Rhagoletis pomonella". Reports of Officers and Committees: Editorial: Ray Joyce asked for suggestions for the improvement of the Index to the Proceedings. Little response was elicited. Liaison: The Liaison Committee has reviewed the Dept. of Land & Nat. Resources proposed Threatened and Endangered Wildlife Plan and prepared a letter containing the Society's comments. They are as follows: 1. Although no insect species is currently on the endangered/ threatened list, entomological expertise should be involved in the surveying and inventorying of endangered species and in establish ing priorities for listing of affected species. 2. The action plan for plants and invertebrates should be integrated rather than compartmentalized. In particular, surveys and action plans should be based on systems rather than individual species. 3. Public awareness and education are given low priority in the plan and are often unscheduled. These activities should be given a higher priority since the success of the program is dependent upon public awareness. S. Saul proposed that mention be made of the inclusion of many Hawaiian spiders and insects in proposed federal endangered species lists and in the (unofficial) international endangered species Redbook. Motion was seconded and carried. W. Mitchell proposed that the letter be amended to recommend that entomologists be involved in identifying information gaps, inventorying native species and developing sampling methods and a priority list. Mo tion was seconded and carried. P. Y. Lai reported on H.R. 231, a resolution that calls upon USDA, APHIS to expedite approval of a proposal to allow Sharwill avocados movement to the U.S. mainland under approved conditions. He also Vol. 28, May 31,1988 7

reported that Calavo, a California-based avocado producer, has strongly opposed the proposal and that it looks unlikely to succeed at present. Announcements: A public meeting on the proposed threatened and endangered wildlife plan will be held on April 18 at 7 p.m. at the Kalanimoku BIdg. There will be a meeting on May 5 at the Department of Land & Natural Resources concerning the control of birds and other indigenous wildlife that have become pests. Reported by L. Nakahara. W. C. Mitchell announced the death in Washington D. C. of Sam Fluker, a member of the Society in the 1960's and 1970's.

Notes and Exhibitions

Marietta exitiosa Compere: Recently while attempting to identify parasites reared from the Egyptian Hibiscus mealybug, Maconellicoccus hirsutus (Green), I encountered a species belonging to the aphelinid genus Marietta Motschulsky which apparently had not been reported previously in Hawaii. Using the key and descriptions by the late Harold Compere (1936, Notes on the Classification of the Aphelinidae, Univ. Calif. Pubs, in Entomol. 6(12): 277-322), the species ran to Marietta exitiosa Compere. However, although the specimens fit Compere's description reasonably well, a direct comparison with his type material will be necessary to fix the identity of the species present here. Specimens were subsequently submit ted by B. Kumashiro to the USDA Insect Identification Lab. in Beltsville, Maryland where they were determined by Dr. R. W. Carlson as Af. exitiosa. The species was described from specimens from South Africa (loc. cit: 312). A review of Marietta material in the Univ. of Hawaii collection yielded 22 specimens of this species (20 Oahu, 2 Maui) collected between January 1969 and November 1983. The material was all collected by myself, except for two, Hana, Maui, II* 12* 1973, N. Miyahara, ex Saissetia miranda (Cockerell & Parrott) on Erythrina, and one, U. H Campus (Manoa), VIII*16*1983, S. F. Swift, ex Maconellicoccus hirsutus. In addition to the above listed hosts, Oahu specimens have been reared from the following Coccoidea: Asterolecanium bambusae (Boisduval), Kilifia acuminata (Signoret), and Saissetia coffeae (Walker). All Marietta species are believed to be hyperparasites of primary parasites which attack various Coccoidea. Two species have been reported previously in Hawaii; M. carnesi (Howard) and M. graminicola Timberlake. J. W. Beardsley. Azotus sp.: Another aphelinid parasite previously unreported in Hawaii is an as yet incompletely identified species ofAzotus Howard. This genus has not previously been reported from our fauna. Three specimens (26 6, 19) were obtained from an infestation of Diaspis boisduvalii Sig noret on Cattleya orchid collected in Honolulu on XII* 1983 by D. M. Tsuda. These scales were heavily parasitized by the encyrtid Coccidencyrtus ochraceipes Gahan, and the Azotus sp. probably is a hyperparasite, the usual habit of this genus. J. W. Beardsley. The Heteropsylla species in Hawaii: Definitive identifications of psyllids in the genus Heteropsylla in Hawaii has been unknown for several 8 Proceedings, Hawaiian Entomological Society years due to the close resemblance of species within the group and due to the collection (for identification) of mixed populations from single hosts in the past. Recently, through the aid of taxonomists Ian Hodkinson and Robert Brown of Liverpool Polytechnic in England, David Hollis of the British Museum of Natural History, and Douglass Miller of the Systematic Entomology Lab. of USDA, Bernarr Kumashiro with other Dept. of Agriculture entomologists were able to "piece together" the Heteropsylla picture in Hawaii through a combination of taxonomic and host specif icity studies. Three species of Heteropsylla occur in Hawaii: 1. Heteropsylla cubana Crawford: Specimens were first collected on Oahu on April 26, 1984 from koa-haole (Leucaena leucocephala). This species was previously reported as Heteropsylla sp. poss. incisa (Sulc) (Nakahara; PHES 26:15). Although leucaena is its major host, this species also attacks monkeypod (Samanea saman), based on subsequent lab reared and field collections. H. incisa is a junior synonym of H. cubana according to D. Burckhardt (1986, Nomenclatorial note on Heteropsylla cubana Craw ford (Homoptera: Psylloidea), a new pest in Pacific countries, Revue suisse Zool., 93(4): 1023-1024; 1987, Zool. J. Linn. Soc, (in press)). H. cubana has been responsible for major leucaena losses in Hawaii and other countries in the Pacific during the past few years. Severe damages have been reported from the Philippines and Saipan where leucaena is heavily relied on for forage, pelleted feedmeal, mulching, green fertilizer, firewood, erosion control and other uses. Miller lists H. cubana collection material from the following areas: Argentina, Bahama Is., Bermuda, Cuba, Dominican Republic, Guadeloupe, Nicaragua, Mexico, Peru, Philippines, Puerto Rico, United States (Florida, Hawaii), Tobago, Trinidad, Virgin Is., and Western Samoa. In addition, Robert Brown (1985) in a thesis on "Studies on the and Ecology of the Jumping Plant Lice (Homoptera: Psyl loidea) of Panama" at Liverpool Polytechnic, England also lists collection material from Panama, El Salvador, and Surinam. More recently, Douglas Waterhouse (personal communication) of CSIRO details the rapid spread of the leucaena psyllid during 1985 into other parts of the Pacific: Cook Is., Fiji, Guam, New Caledonia, American Samoa, Saipan, Solomon Is., Tonga, Vanuatu, and Yap. 2. Heteropsylla huasachae Caldwell: Three adult specimens were first collected on Oahu on May 30, 1975 from general sweepings of various legumes (Beardsley; PHES 22(3): 407). Subsequent surveys in the late I970's revealed Heteropsylla populations on slender mimosa (Desman- thus virgatus) but not on klu (Acaciafamesiana). This species was previously referred to as Heteropsylla sp. poss. mimosae and as Heteropsylla sp. no. 3. On April 17, 1984, this species was also found attacking the terminals of monkeypod trees in Honolulu. Mixed populations of//, cubana and H. huasachae on monkeypod further added to the confusion over the identity of either species. Psyllid collections from monkeypod was previously referred to as Heteropsylla sp. no. 2. Vol. 28, May 31, 1988 9

3. Heteropsylla fusca Crawford: Specimens of this psyllid were first collected by Bernarr Kumashiro on January 1, 1986 from klu (A. farnesiana) at St. Louis Heights, Honolulu, Oahu. This is the first observa tion of a breeding psyllid population on klu in Hawaii and represents a new state record. L. M. Nakahara. Schizomus siamensis (Hansen): (Class Arachnida, Order Schizomida, Family Schizomidae). The schizomid from Mo'ili'ili limestone caves, Ho nolulu that was displayed at the March 12,1979 meeting of the Society was tentatively referred to as a Trithyreus sp. (PHES 24:8). It has now been determined as Schizomus siamensis (Hansen) by James Redell and James Cokendolpher of the Texas Memorial Museum, Austin. They have a brief paper on a rediagnosis and distribution of this species on Pacific Islands in press in the Japanese Journal, Acta Arachnologica. S. siamensis has consistently been one of the most abundant in the limestone caves of Mo'ili'ili area of Honolulu on each of my visits, the last being in April, 1985. Fred Stone and I collected over 30 indivi duals in a small pitfall trap set on the mud floor in darkness from March 24 to April 27, 1983. Mr. Grant Uchida and Dr. J. W. Beardsley of the Univ. of Hawaii reported on the only non-cave collection of a schizomid in Hawaii in PHES 24:182-183. Mr. Uchida collected a single specimen of presumably this species from an abandoned termite gallery in Kaimuki area of Honolulu on February 1, 1980. F. G. Howarth.

MAY

The 965th meeting of the Hawaiian Entomological Society was called to order by President Lai at 2 p.m. on May 12,1986 at the Manoa Library. Eighteen members and 2 guests attended. Guests were Linden Teramoto (U.H.) and William Hoy (Hawaiian Evolutionary Biology Project). Program: Noel Krauss, retired exploratory entomologist for the Hawaii State Department of Agriculture spoke on "Entomology in the South Pacific". Report of Officers and Committees: Treasurer: Stan Higa reported that the balance in the treasury is $7,564.22. Science Fair: P. Y. Lai reported for the Committee (Tabashnik and Gushing) that two projects were selected for recognition by the Society, both done by students at McKinley High School. They were: L. K. W. Lee: Sexual selection in Drosophila melanogaster. M. K. C. Tom: Isolation, identification and preliminary studies of the internal bacterial flora in the Mediterranean Fruit Fly. Tsuda moved that a $30 first prize and a $20 second prize be awarded to Lee and Tom respectively: motion was seconded and carried. Bianchi moved that the winners be invited to the July 14 meeting; motion was seconded and carried. New Business: Dr. Beardsley moved that the June meeting be held in Hilo to coincide with the Hawaiian Natural History Society meetings. 10 Proceedings, Hawaiian Entomological Society

Discussion centered on the availability of facilities, speakers, etc. Motion was seconded and carried.

New State records: Gasteracantha sp.: Specimens of this spiny backed spider (Araneae: Araneidae) were collected in a residential area of Hilo on the island of Hawaii on Dec. 16,1985 by E. Smith and submitted to the Hawaii Dept. of Agriculture. It was forwarded to J. Coddington of the Smithso nian Institution who identified it as Gasteracantha sp. This is a new state record. According to Coddington, it is an old world species. This spider is reportedly becoming a nuisance problem because of its webbing in resi dential areas and near beekeeping areas. It somewhat resembles G. can- criformis (L.), which is found in Hawaii (Fullaway 1955, PHES 25:378) except that this new immigrant has shorter spines and two distinct yellow spots on its dorsum. B. Kumashiro. New island records: Ecacanthothrips tibialis (Ashmead): Specimens of this thrips (Thysanoptera: Phlaeothripidae) were collected on a dead citrus branch in Hilo on the island of Hawaii in Nov. 1985 by S. Matayoshi. Identifica tion was made by K. Sakimura. This is a new island record. It was first found on Oahu in 1981 (PHES 24:191). This thrips is a fungus hyphae or fungus decomposition by-product feeder, usually found living among dead trees. S. Matayoshi. Aspidiotus destructor Signoret: Specimens of this scale (Homoptera: Diaspididae) were collected from coconut from Kekaha, Kauai in March 1986 by R. Heu, D. Sugawa, and D. Melendez. Identification was made by B. Kumashiro, HDOA. This is a new island record. This scale was first found on Oahu in 1968 (PHES 20:279) and later on the island of Hawaii in 1977. R. Heu & D. Sugawa. Leptodictya tabida (Herrich-Schaeffer): Specimens of this major pest of sugarcane (Hemiptera: Tingidae) were found on sugarcane at Keawanui, Molokai in March 1986 by P. Conant. Identification was made by B. Kumashiro, HDOA. It was previously found on Maui infesting sugarcane in May 1985 (PHES 27:10). P. Conant. Ischnaspis longirostris (Signoret): Specimens of the black thread scale (Homoptera: Diaspididae) were collected from banyan at Kalaheo, Kauai on Feb. 25, 1986 by L. Ishii, HDOA. Identification was made by B. Kumashiro, HDOA. This is a new island record for this scale which now occurs on all the major Hawaiian islands. L. Ishii. New Hawaii host records: Toxoptera aurantii (Boyer de Fonscolombe): A small infestation of Toxoptera aurantii (Homoptera: Aphididae), the black citrus aphid, was found on mock orange in the lower Makiki area of Honolulu in Feb. 1986 by R. Heu and G. Funasaki. Identification was made by B. Kumashiro, HDOA. This is a new host record. Other hosts include macadamia, Vol. 28, May 31,1988 11

kamani, coffee, ixora, pomelo, lime, mango, hibiscus, pittosporum, and vanda orchid. This aphid occurs on all the major Hawaiian islands. R. Heu and G. Funasaki. Imma mylias Meyrick: Several immature specimens of this mic- rolepidoptera (Glyphipterigidae) were collected by sweeping Acacia con- fusa foliage in the round top area of Honolulu on Jan. 21, 1986 by K. Murai.G. Funasaki, and S. Benzonof HDOA. The specimens, which were nearing pupation, were reared to adulthood and identified by B. Kumashiro, HDOA. Acacia confusa is a new host record for this moth. Other hosts includeAlbizzia,klu, monkeypod, and opiuma. This moth was found on Oahu in 1973 (PHES 22:391), and on the island of Hawaii in 1975. K. Murai.

JUNE

The 966th meeting of the Hawaiian Entomological Society was called to order by the President at 2 p.m. on June 9, 1986 at the University of Hawaii at Hilo. Nine members and 5 guests (Gordon Grodh, Brian Bushe, Dalen Kawakami, Trent Hata, and Roddy Nagata) were in attendance. Program: Lorna Arita, College of Agriculture, U. of H. at Hilo spoke on "The quantity and color type of pollen collected from a honey bee hive at U. of H., Hilo Agriculture Instructional Farm, Panaewa, Hawaii". No reports of officers and committees or other business was trans acted.

Plagithmysus (s.str.) cheirodendri Gressitt and Davis associated with Myr- sine: The rearing of this species from Myrsine lessertiana (DC.) Seem is the first association of any species of Plagithmysus with Myrsine on the island of Maui. This rearing has produced the second and third known specimens of cheirodendri and the first conclusive association between this insect and its plant host. These specimens emerged on May 9 and ca. June 3, 1986 from a branch of kolea collected by A. C. Medeiros at Waikamoi, Haleakala at ca. 1830 m elevation. The holotype of cheirodendri was col lected by McMahon at Paliku, Haleakala Crater, 2000 m, Aug. 1958 on olapa, Cheirodendron trigynum (Gaud.) Heller. At Paliku, both olapa and kolea grow together, so it is probable that the holotype collected on olapa had actually emerged from kolea. This plagithmysine is a showy species and rather distinct from close relatives by having the pronotum with 6 distinct tubercles and 4 patches of yellow pubescence; also, the elytral stripe is broader than in most of the larger striped species of Plagithmysus. Only two other plagithmysines have been associated with Myrsine and both are of the nominate subgenus and from the island of Hawaii: giffardi Perkins andsimplicicollis Sharp. The former is remarkable in that it is alsoa borer of Smilax, Liliaceae. G. A. Samuelson & C. J. Davis. 12 Proceedings, Hawaiian Entomological Society

Ceratosmicra campoplegicis Burks: In 1978, Dr. Beardsley re ported a Ceratosmicra sp. (Family Chalcididae) as a new state record (PHES 23:312, 1981) based on a single male specimen from Lanai. Since that time two additional female specimens of the same species have been collected; one from Maui (Kula, Jan. 1982, L. Yudin Col., reared from Plutella material on cabbage, with Diadegma insularis), and one from Kauai (Kokee Road, 3,000 ft. 22«IX«1982 J. Takara, ex Malaise trap). The Kauai speci men was submitted to the USDA Insect Identification laboratory in Beltsville, Md., and has been determined as C. campoplegicis Burks by Dr. R. W. Carlson. C. campoplegicis was described in 1968 (Proc. Ent. Soc. Wash. 70:172) from California. It, like all Ceratosmicra spp., is a hyper- parasite, having been reared from Apanteles koebelei Riley and an unde termined Campoplegini (Ichneumonidae) in California and, apparently from Diadegma insularis on Maui. J. W. Beardsley and B. Kumashiro. Ceratosmicra immaculata (Cresson): A single female of a second species of Ceratosmicra was found by Beardsley in the collection of a student in general entomology and U. H. Manoa in May, 1985. The specimen is labeled Kaimuki, Honolulu, April 1985, T. Y. Mashima collector. Subsequently an additional female and two males of this species were collected on the grounds of the State Dept. of Agriculture in Hono lulu on Feb. 14, 1986 by A. Higa. These specimens were tentatively determined as Ceratosmicra immaculata (Cresson) by Dr. Beardsley. This determination was confirmed by R. W. Carlson of the USDA Systematic Ent. Lab. in Beltsville, Md. C. immaculata was described by Cresson (1865, Proc. Entomol. Soc. Phila. 4:97) in the genusSmicra. Burks (1940, Proc. U. S. Nat. Mus. 88:343-351) revised the North American Ceratosmicra spp. and included Cresson's immaculata. The known distribution of this species is listed in Krombein et al 1979 (Cat. Hymenop. in America No. of Mexico 1:868) as Texas, Mexico, Central and S. America. The hosts listed for it are Apanteles sp, Campoletis sonorensis (Cameron) and Meteorus sp. Speci mens collected at DO A grounds in Honolulu were reared from cocoons of Cotesia ruficrus (Haliday). This is a new state record. J. W. Beardsley and B. Kumashiro. Mesostenus gracilis Cresson: Two specimens of a previously unrec orded immigrant ichneumonid wasp, placed by Dr. Beardsley in the genus Mesostenus (Gelinac), were submitted to the USDA Insect Identifi cation Lab. by Mr. Kumashiro. These were determined by R. W. Carlson as Mesostenus gracilis Cresson. The specimens submitted were a male from Pohakuloa, Hawaii 6,000 ft., 17*VI* 1966, J. W. Beardsley, and a female, Maui, Haleakala N.P., Holua, 6,900 ft., 3« VI* 1977, J. W. Beardsley. An additional female and two males are in the U. H. Entomology Dept. Collection. The female is from Koko Head, Oahu 27«IM982 and the males bear the same collection data as the Pohakuloa male previously cited. This is a new state record. M. gracilis was described in 1864 (Proc. Entomol. Soc. Phila. 3:315) and is widely distributed in North America and Mexico. It has been frequently reared from larvae of phycitid moths associated with stored products. The recorded hosts include Anagasta Vol. 28, May 31,1988 13

kuehniella (Zeller), Cadra figulilella (Gregson), Ephestia elutella (Huebner) and Homeosoma electellum Hulst (Krombein et al, 1979. Cat. Hymenop. in Amer. N. of Mexico 1:470). All these species except the last are known to be present in Hawaii. No Hawaiian host records are available for M. gracilis; however, the presence of this species in remote areas such as Pohakuloa and Haleakala Crater suggests that it may be parasitizing native phycitid moth larva here. J. W. Beardsley and B. Kumashiro. Megastylus flavopictus (Gravenhorst): This determination was re ceived from the USDA Insect Identification Lab. for a female specimen of a very small ichneumonid wasp, collected at Kokee, Kauai, 3,000 ft., 19*V*1982. J. Takara, ex Malaise trap. Two additional specimens from the same general area are in the U. H. Entomology Department Collec tion, one labeled Kokee, Kauai 3,000 ft., 2O'V«1982, J. Takara, collector, and one Kauai, 2,000 ft., Kokee Road, 10«IM982, J. Takara, ex Malaise trap. This is a new state record. Megastylusflavopictus was described origi nally from Europe (Gravenhorst, 1829 Ichneum. Europaea 2:983) in the genus Plectiscus. It is also widely distributed in North America (Krombein etal, 1979. Cat. Hymenop. in America N. of Mexico 1:733). It is placed in the subfamily Oxytorinae (= Microleptinae), a group previously un known in Hawaii. Townes (1971, Mem. Amer. Entomol. Inst. 17:306) indicates that species of Megastylus have been reared from "Fun- givouridae" (= Mycetophilidae), presumably from larvae or pupae. It is possible this species may be parasitizing endemic Mycetophilidae on Kauai. J. W. Beardsley and B. Kumashiro. Megachile chlorura Cockerell: On January 5, 1979, a female speci men of an unknown megachilid bee was found in light trap material from Hickam Air Force Base by J. W. Beardsley. Subsequently Dr. Beardsley has found more than two dozen specimens, mostly females, of this bee in the collections of students in the general entomology course at the Uni versity of Hawaii. All of the specimens are from Oahu. Specimens were given to Mr. Kumashiro who sent two pairs to the Insect Identification Lab., USDA where they were determined as Megachile chlorura by S. W. T. Batra. This is a new state record. C. chlorura was described from a female specimen collected at Mt. Maquiling, Laguna, Luzon, Philippine Islands (Cockerell 1918, Philippine Jour. Sci. D 13:136) and this is the first record of the species outside of the Philippine Islands. J. W. Beardsley and B. Kumashiro.

Notes and Exhibitions

Notes on Hawaiian Serphidae (formerly Proctotrupidae): Hawaiian entomological literature records two species of Hymenoptera of the fam ily Serphidae as occurring in Hawaii. These are Proctotrupes hawaiiensis Ashmead (1901, Fauna Hawaiiensis 1:294) and Exallonyx philonthiphagus Williams (PHES 8:205). In 1981, Henry and Marjorie Townes published a Revision of the Serphidae (Hymenoptera) (Mem. Amer. Entomol. Inst. 32) in which they presented nomenclatorial evidence supporting the use of the family name Serphidae, rather than Proctotrupidae which has been in general usage in the United States (eg: Krombein et al, 1979. Cat. Hymenoptera in Amer. No. of Mexico). Furthermore, in their work the Townes have placed P. hawaiiensis in the genus Brachyserphus, forming the new combination Brachyserphus hawaiiensis (Ashmead). E. philonthiphagus is placed by them as a synonym of Exallonyx trifoveata Kieffer, a widely distributed species known elsewhere from North America, Europe, New Zealand, Tasmania and South Africa. Recently I have found two specimens of a second, as yet undetermined species of Exallonyx in light trap material from Hickam Air Force Base, Oahu. The first specimen was collected during April 1982; the second in June 1985. J. W. Beardsley. Copidosomopsis plethorica (Caltagirone): In February 1982 Mr. Moshen Ramadan, a graduate student in entomology at U.H. Manoa, reared a long series of female specimens of a polyembryonic encyrtid wasp from a larva of the carob moth, Ectomyelois ceratoniae (Zeller), which he had collected from a seed pod of Erythrina sp. on the University campus in Manoa. I tentatively determined the species as Pentalitomastix plethorica Caltagirone, a species known to attack certain tortricid and phycitid moth larvae, including E. ceratoniae in California. Additional specimens were reared from carob moth larvae by Ramadan in 1984, and some of these were sent to Dr. Caltagirone at the University of California Division of Biological Control, Albany, CA. Dr. Caltagirone recently has written that Vol. 28, May 31,1988 15

the species is almost surely his plethorica, but that males (which have not yet been found among the Hawaiian specimens) should be studied to fully confirm this. He also pointed out that Pentalitomastix is now considered to be a synonym of Copidosomopsis Girault (see Ann. Entomol. Soc. America 78:705-708, 1985). This is a new state record. J. W. Beardsley. Eupelmus allynii (French): In a note on the eurytomid seed chalcid Bruchophagus mellipes Gahan (Beardsley 1983, PHES 24:173), an associ ated eupelmid parasitoid was reported as Eupelmus eustichus Perkins, an apparently endemic species described in Fauna Hawaiiensis. This deter mination was in error. Specimens of the same Eupelmus recently were reared from puparia of the Hamakua pamakani gallfly, Procecidocharis alani Stone, collected at Hualalai Ranch, Hawaii by S. Matayoshi of the Hawaii State Dept. of Agriculture, and a female was reared from Eupatorium material collected at the summit of Mt. Kaala, Oahu in Sep tember 1979 by K. Adee. When these specimens were compared with the original description off. eustichus it was apparent that they were not conspecific with it. Specimens were submitted to the USDA Insect Iden tification Lab. in Beltsville, Maryland and were determined by R. W. Carlson asEupelmus allynii (French). E. allynii is a widely distributed North American species which has a wide host range on insects living in galls, seeds, plant stems and the like (Krombein et al. 1979. Hymenop. in America No. of Mexico 1:880). This apparently accidentally introduced eupelmid is a new state record. J. W. Beardsley and B. Kumashiro. Mesomorphus vitalisii Chatanay: More than 30 specimens of a pre viously unrecognized black tenebrionid beetle were found in light trap collections from Hickam Air Force Base, Oahu duringjune-August 1985. Specimens submitted to the USDA Insect Identification Lab. were iden tified by T. J. Spilman as Mesomorphus vitalisii Chatanay. No information has been obtained on the origin or biology of this species. This is a new state record. J. W. Beardsley and B. Kumashiro. Ozognathus sp., possibly exiguus Gorham: Another new immigrant beetle which, to date, has been found only in light trap collections from Hickam Air Force Base, Oahu, is a small anobiid of the genus Ozognathus. The first specimen was found in November 1978, and 10 additional specimens were taken during 1982-85. The determination was made by R. E. White of the USDA Systematic Entomology Lab. who stated that our species may be O. exiguus Gorham which is known from Central America. Nothing apparently is known concerning the biology of O. exiguus, but a related North American species, O. cornutus Leconte, has been reported from dead flower stalks, dried twig terminals of avocado, and similar habitats. One sex of this beetle (male ?) has a pair of conspicuous horn-like projections which extend upward from the bases of the mandibles. This is a new state record. J. W. Beardsley and B. Kumashiro. Genus near Ostoma sp.: Three specimens of an unknown beetle belonging to the family Trogositidae have been collected on Oahu. The first specimen, which was collected in a light trap at Hickam Air Force Base in May 1981, by J. W. Beardsley was submitted to the USDA Insect 16 Proceedings, Hawaiian Entomological Society

Identification Laboratory. A determination of "Genus unrecognized, near Ostoma sp." was made by J. M. Kingsolver who noted that literature on this family is scattered and of little assistance in making identifications. Two additional specimens of this beetle are in the collection of the U. H. Entomology Dept., both from Oahu. One was collected at Aiea on 27'XI* 1983 by S. Omon, the other on Round Top Drive (Honolulu), 300 feet, X*l 0*1981, W. D. Perreira. This is a new state record. J. W. Beardsley and B. Kumashiro. Neohydatothrips (Sercothrips) variabilis (Beach): On May 12, 1986 several adult thrips were collected by R. Mau and D. Tsuda from leaves of potted marigold plants sitting in the Entomology Dept. office, U. H. These potted plants were propagated in an open-type greenhouse at the Pearl City Instructional Facilities, U. H. Additional specimens were collected by D. Tsuda at the Pearl City facilities on May 19,1986 on leaves of both potted and ground-planted marigolds. Infested leaves were char acterized by silvery streaks and patches. Identification of the specimens was made by K. Sakimura. This constitutes a new state record. N. variabilis (Beach) is commonly known in the United States as the soybean thrips. U. S. distribution includes Arizona, California, Georgia, Illinois, Iowa, Massachusetts, Maryland, Mississippi, Tennessee, Texas, Utah, and now Hawaii. Other areas include parts of British Columbia and Mexico. Possible host plants include: clover, hackberry, hawthorn, smartweed, cucumber, clematis, elm, grass, cotton, willow, crabapple, Viburnum, ragweed, basswood, grape, oak, orange, sage, and cotton- wood. It will also feed on spider mites. D. Tsuda and K Sakimura. Sciothrips cardamomi (Ramakrishna): Approximately 12 adult thrips (Thripidae), males and females, were recovered by D. Tsuda from samples of pink ginger flower cuttings submitted to the Insect Diagnostic Lab. on March 24, 1986. The pink ginger cuttings were collected by A. Hara from a commercial greenhouse in Pahoa, Hawaii. Identification of the specimens was made by K. Sakimura. This constitutes a new state record. 5. cardamomi is commonly known as the cardamom thrips in India, where it is a serious pest of Cardamon, a ginger plant grown for its spicy seeds. This thrips feeds on flower petals and the young leaves of ginger plants. It has been recorded only from India and Hawaii. D. Tsuda and K. Sakimura.

AUGUST

The 968th meeting of the Hawaiian Entomological Society was held at the Manoa Library at 2 p.m. on August 11,1986. Seventeen members and 2 guests were in attendance. Guests were: John Moxon (DPI, Papua New Guinea), and Bruce M. Furlow (Preventative Medicine, Tripler Army Medical Center). Vol. 28, May 31, 1988 17

Program: John Moxon, Department of Primary Industry, Rabaul, Papua New Guinea, spoke on "Biological control of Pantorhytes weevil pests of cocoa in Papua New Guinea by the crazy ant, Anoplolepis longipes". Reports of Officers and Committees: Treasurer: Stan Higa reported a balance of $7,865. in the trea sury. New Business: Larry Nakahara — The Society has received a re quest for comment on a proposed eradication of marijuana on Maui, Molokai and Hawaii. The project will be very similar to the one last year on Kauai. It will involve the use of glyphosate and/or diesel oil applied to the plantings by backpack sprayer or by helicopter. Birds and plants are the only impacted organisms mentioned in the assessment report; no men tion of the effect on insects was made. The closing date for comments is August 22. Mitchell suggested that the letter state the Society's concerns on the program's effects on endemic insects and that the proposal does not offer enough information to make an informed comment. Samuelson suggested that the eradication efforts, especially in the kipukas on the Big Island, be carefully done so as to have minimal impact on the native biota. Nakahara moved that a letter be written stating general approval of the proposal in spite of the lack of information on the effect on insects. The motion was seconded and carried.

Notes and Exhibitions

Elasmopalpus lignosellus (Zeller): The collection of this lesser cornstalk borer (Lepidoptera: Pyralidae) records a new immigrant pest insect for the state. This pyralid was first discovered damaging young sugarcane plantings on the leeward side of Kauai on July 9, 1986 by Dr. Asher Ota of the Hawaiian Sugar Planters' Association (HSPA). The tentative identification was made by Dr. Ota. Joint HSPA-HDOA surveys revealed additional infestations on newly planted sugarcane in central and northern Oahu on July 1 lth and in central and western Maui on July 15th. A young corn planting in Kunia, Oahu was also damaged by the feeding activity of this borer. Damage is caused by the larval stage which bores and feeds within stems of young sugarcane and corn plants. Such activity quickly kills host seedlings amd severely weakens plants that survive. The lesser cornstalk borer has a wide host range of at least 60 species of plants, mainly in the legume and grass families. Common crop hosts include sugarcane, corn, sorghum, peanuts, beans, and cowpeas. The world distribution of E. lignosellus includes the Caribbean islands, Mexico, Central and South America, and the continental U.S.A. HSPA, HDOA, USDA, and Univ. of H. entomologists met to discuss control methods for the borer. Insecticidal application will be looked into 18 Proceedings, Hawaiian Entomological Society as a short-term solution. Cultural and biological control methods will be explored as long-term strategies. Ron Heu. discoidea (Fabricius): This Holarctic nitidulid may now be officially added to our fauna, as more specimens were collected from Haleakala, Maui. This species had only been known here by the single individual reported by Zimmerman in 1939 (PHES 10:333). This speci men was collected from a greasy can on Haleakala in 1919 by P. H. Timberlake; it is now kept in the HDOA collection. In 1985, F. R. Cole collected this species from pitfall traps near Kalahaku overlook, Haleakala at ca. 2745 m elevation. Two specimens were collected in May and two in August from an "non-ant area" and one specimen was collected in August from an "ant area'. This secretive species is an example of a temperate region insect that has become established in a restricted area in the state. Its distribution here appears to be limited to the cooler, higher elevations of E. Maui. This species is keyed in the Zimmerman article cited above. I wish to thank T. N. Seenoand I. E. Savage of California Dept. of Food and Agriculture in Sacramento for confirming the identity of this species. G. A. Samuelson.

SEPTEMBER

per annum. Notes and Exhibitions: None. Meeting adjourned at 2:50 p.m.

OCTOBER

The 970th meeting of the Hawaiian Entomological Society was called to order by President Lai at 2 p.m. on October 20, 1986 at the Manoa Library. Twenty members and 4 guests were in attendance. The guests were: Linden Teramoto, U. of H. Genetics, Scott Miller, B. P. Bishop Museum, Hannalore Hod, and Manfred Asher. Vol. 28, May 31,1988 19

Program: Arnold Hara, U. H. Hilo, spoke on "Management of Orchid, Protea, and Anthurium Pests". Reports of Officers and Committees: Membership: Applications for membership were received from: Ellen Shimakawa, U. of H. Genetics Dept., Lance Suehara, Hawaii DOA, Hilo, and Scott Miller, B. P. Bishop Museum. All were unanimously elected to membership. Editorial: Ray Joyce reported that galley proofs for Vol. 27 of the Proceedings have been checked and returned to the printer. Dinner meeting: Ron Heu reported that the Officers Club at Tripler has been reserved for Dec. 8th and Mongolian Bar-B-Q is on the menu. Lynn LeBeck pointed out that the Dec. 8 date conflicts with the ESA National meeting in Reno. P. Y. Lai directed Ron Heu to try to set up another date for the dinner and to try to fix the price. Liaison Committee: Dr. P. Y. Lai, as a representative from the Hawaii Dept. of Agriculture, has attended the meetings of the Hawaiian Technical Advisory Committee on Pesticides and offered to discuss those deliberations with interested persons. Nomination: The following candidates will run for office for 1987 President Elect—Jack Armstrong; USDA, ARS, Hilo; Wilmer Snell; USDA, PPQ, Honolulu Secretary — Lynn LeBeck; U. of H., Honolulu; Nick Liquido; USDA, ARS, Hilo Treasurer — Nancy Cushing; U. of H., Honolulu; John Strazanac; U. of H., Honolulu Advisor — Roger Vargas; USDA, ARS, Honolulu; Stephen Saul; U. of H., Honolulu The following members have been nominated for Honorary Membership. They are: Toshiyuki Nishida, Martin Sherman, Ryoji Namba, Bernard Sugerman, Wallace Mitchell, and Elwood Zimmerman. Their names will appear on the ballot. Announcements: Scott Miller (B. P. Bishop Museum) — The museum has made much progress in stabilizing its finances in the past two years and is still actively seeking funding for its entomological activities and collections. They hope to rebuild the collections program and resume some of the discontinued publications in systematic entomology. The Museum thanks the public for its support during the Museum's recent financial crisis. Marshall Johnson — Reported that the Western Regional Biologi cal Control Meeting will be held on campus at U. of H. on October 22-24. P. Y. Lai — Announced that an international conference on the control of the psyllids attacking Leucaena glauca will be held in November on Molokai. Contact W. C. Mitchell for details. Bid for the construction of the proposed Med Fly facility in Waimanalo was § 1.3 million over the funds that have already been ap proved. This leaves USDA with the following alternatives: 1. Forget the 20 Proceedings, Hawaiian Entomological Society

project, 2. Request additional funds from Congress, or 3. Scale down the size of the project. The ground breaking has been postponed again.

Notes and Exhibitions

Diabrotica undecimpunctala Mannerheim and subsp. howardi Barber: The nominate form, D. u. undecimpunctata or the "western spotted cucumber beetle", is nearly always the form that is intercepted in Hono lulu by Plant Quarantine. It ranges in the western US. Recently, one specimen of the subsp. howardi was intercepted in Honolulu; it was found in an aircraft from St. Louis, Missouri on 12«IX«1986by R. Oda (specimen in HDOA). This subsp. is called either the "spotted cucumber beetle" or the "southern corn rootworm" and it ranges in the eastern and southern parts of the US. It differs from the nominate subsp. by having the abdomen and parts of the legs yellow instead of entirely black. The synonymy includes D. soror LeConle, the name under which this species was reported in the state by Beardsley (1964, PHES 18:340). Diabrotica duodecimpunctata (Fabricius) is also a junior synonym (see Wilcox, 1972, Coleopt. Catalogus suppl. pars 78(2);334). Upon checking intercepted specimens of this species in the HDOA and Bishop Museum collections, only the specimen cited above is referable to subsp. howardi. Most of the nominate undecimpunctata specimens are from the 1985-6 period and most (32) arrived in lettuce or spinach shipments; four came in on squash; two on endive; one on mustard greens; and one on mums. Almost all these records are from shipments that originated from California. So far as known, this species has not become established in Hawaii, though it frequently reaches the state. On the basis of the 1985-6 collections, the intercepts ofDiabrotica in Honolulu averaged over 20 specimens per year. G. A. Samuelson. New Island Records: Fruit-piercing moth, Eudocima fullonia (Clerck) (Lepidoplera: Noctuidae): Specimens were collected at Keawa Nui, Molokai on Erythrina variegala var., Tropic Coral (a coral tree used as a windbreak) on Sept. 15, 1986 by P. Conant and R. Heu. Specimens were also collected at Kahului, Maui on the same type of Erythrina on Sept. 19, 1986 by J. Tavares. Identification was made by B. Kumashiro, HDOA. Molokai and Maui are new island records. This moth was first found on Oahu in January 1985 and was later found on Kauai in April 1985 (PHES 27:4). Larvae of this moth feed on leaves of Erythrina while the adult is recorded to attack fruit such as papaya, guava, citrus, mango, tomato, and banana. R. Heu. Pseudococcus dendrobiorum Williams (Homoptera: Pseudococ- cidae): Specimens were collected off roots of potted Dendrobium or chids from the Waikiki area of Honolulu on July 14, 1986 by R. Camp. This record for Oahu constitutes a new island record. Identification was made by B. Kumashiro and confirmed by J. W. Beardsley. P. dendrobiorum was first collected in the state on the island of Hawaii in 1976 (Beardsley, PHES 27:9 and 23:183). R. Heu. Vol. 28, May 31,1988 21

Leucothrips thcobromae (Priesncr): (Thysanoptera: Thripidae: De- ndrothripini): On May 12, 1986 several adult thrips, both males and females, were collected from the underside of young castor bean (Ricinus communis) leaves by D. Tsuda at the Pearl City Instructional facility, U. of H. Infested leaves showed typical symptoms of thrips feeding damage, primarily alongside the midrib of each leaf. There were only a few thrips per leaf. Specimens were identified by D. Tsuda (U.H.) as Leucothrips theobrotnae (Priesner). This constitutes a new state record. Hawaii now has two of the five species of Leucothrips recorded in the world. L. theobrotnae was previously recorded from Surinam S.A., feeding on young leaves of cacao. D. M. Tsuda. Pseudanophothrips sp. (Thysanoptera: Thripidae: Thripini): In May of 1986, daily swarms of an unknown thrips were plaguing visitors to the refreshment center at the Mauna Loa Macadamia Nut Co. at Keaau, Hawaii. On May 20, 1986, adults taken by G. Ueunten from the counters and tabletops of the refreshment center were sent to the U. of H. for identification. Mounted specimens were forwarded to K. Sakimura, who stated that we were probably dealing with an undescribed species, very close to the genus Frankliniella. On June 9, 1986, G. Ueunten and D. Tsuda discovered large numbers of nymphal and adult thrips in the male flower cones of Norfolk Island pines (Araxicaria heterophylla) used as windbreaks throughout the macadamia orchard. On June 18, 1986, K. Sakimura recovered numerous nymphs and adults of this unusual thrips from fallen male flower cones of Norfolk Island pines growing in the Waahila State Park, St. Louis Hts., Oahu. The groundskeeper reported that visitors to the park were bothered by swarms of small brown bugs during April and May. Suspecting that this unknown thrips probably originated from New Zealand or Australia, Sakimura sent specimens to L. A. Mound (British Museum) who recog nized the thrips as belonging to the difficult Australian genus Pseudanophothrips. L. A. Mound also stated that he has an identical series of thrips collected from male cones of Bunya-Bunya (Araucaria bidwilli) growing in Queensland, which he plans to describe. This constitutes a new state record for Hawaii. Little is known about this thrips. It is suspected of feeding on both pollen and plant juices within the male cones maturing on the tree. A mature male flower cone (Norfolk Island pine) still yielded a few adult thrips three months after being placed in a paper container. D. M. Tsuda.

NOVEMBER

The 971st meeting of the Hawaiian Entomological Society was called to order by President Lai at 2 p.m. on November 10, 1986 at the Manoa Library. Twenty-two members and 2 guests (Hannalore Hod, and Man fred Asher) were in attendance. 22 Proceedings, Hawaiian Entomological Society

Program: The program was as follows: Lee Yudin — Thrips colonization of weeds and crops. Gail Mason — Pyrethroid resistance in Liriomyza leafminers. Aubrey Moore — Identifying flying insects with a microcom

puter. Old Business: Ron Heu reported on plans for the annual dinner meeting. It will be held on December 18 at the Tripler Officers Club. A buffet dinner menu was selected with ham, fried chicken and ribs. A 10% gratuity will be charged. The ballot, reservation form and program an nouncements will be mailed out to the membership. Po-Yung Lai, for the Executive Committee, recommended to the general membership that the Editorial Committee of the Proceedings be enlarged to include one mainland member and one International member. The recommendation was moved, seconded and approved by voice vote.

Notes and Exhibitions

Aspidiella hartii (Cockerell): (Homoptera; Diaspididae): A diaspid scale was found infesting a sample shipment of tumeric (Curcuma domes- tica) rhizomes during a routine inspection by USDA, PPQ, Officer, Ed ward Uyeda on October 29, 1986. The shipment originated from a one-acre planting located between Kea'au and Pahoa on the Big Island. The scale was identified as Aspidiella hartii (Cockerell) by R. Kunishi, USDA, APHIS, PPQ and confirmed by V. Blackburn, USDA, Beltsville, Maryland. Known hosts include yam (Dioscorea sp.), ginger (Zingiber), and tumeric. S. Nakahara of the USDA, ARS, Systematic Entomology Lab. lists the distribution of this diaspid as Caribbean Islands, Honduras, Panama, Ecuador, Ivory Coast, Ghana, Nigeria, Sierra Leone, Zambia, India, Malaya, Philippines, Hong Kong, and Fiji. A preliminary survey by USDA and the Hawaii Dept. of Agriculture at the original tumeric plant ing indicated a 50-60% infestation of the rhizomes by this scale. This is a new immigrant record for the state. R. Heu.

DECEMBER
