PROCEEDINGS of the HAWAIIAN ENTOMOLOGICAL SOCIETY for 1978 VOL XXIII No. 3 February 1981 Information for Contributors Manuscripts for publication, proof, and other editorial matters should be addressed to: Editor: Hawaiian Entomological Society c/o Department of Entomology University of Hawaii 3050 Maile Way, Honolulu, Hawaii 96822 Manuscripts should not exceed 40 typewritten pages, including illustrations (approximately 20 printed pages). Longer manuscripts may be rejected on the basis of length, or be subject to additional page charges. Typing — Manuscripts must be typewritten on one side of white bond paper, &Vi x 11 inches. Double space all text, including tables, footnotes, and reference lists. Margins should be a minimum of one inch. Underscore only where italics are intended in body of text, not in headings. Geographical names, authors names, and names of plants and animals should be spelled out in full. Except for the first time they are used, scientific names of organisms may be abbreviated by using the first letter of the generic name plus the full specific name. Submit original typescript and one copy. Pages should be numbered consecutively. Place footnotes at the bottom of the manuscript page on which they appear, with a dividing line. Place tables separately, not more than one table per manuscript page, at end of manuscript. Make a circled notation in margin of manuscript at approximate location where placement of a table is desired. Use only horizontal lines in tables. Illustrations — Illustrations should be planned to fit the type page of 4'/2 x 7 inches, with appropriate space allowed for captions. Number all figures consecutively with Arabic numerals. If figures are to be subdivided, use capital letters (A, B, C, etc.) to designate sub divisions. Where possible, figures should be grouped compactly into page-size plates. Photo graphic prints should be cropped to eliminate unnecessary margins. All figures should be se curely mounted on stiff posterboard with identifying information (author, title of paper, and figure number(s)) placed on the back. If possible, do not submit original drawings, but reduce photographically and submit prints (glossy or matte) no larger than 9 x 14. The Editor cannot be held responsible for lost art work. Two copies of all illustrative material should be submitted. Figure captions should be typewritten, double-spaced, on a separate page, headed "Captions for Figures," and placed in the manuscript following the list of references. Do not attach figure captions to illustrations. References — Citations in the text should be by author and date. Beginning on a separ ate page at the end of the text, list references cited alphabetically by author. List titles of arti cles as well as journal citations. See article in this issue for proper style in listing references. Examination of articles in this issue will help in conforming to the style of presentation desired. The editorial style of the PROCEEDINGS essentially follows the Council of Biology Editors Style Manual (Third Edition, A.I.B.S., 1972). Manuscripts which fail to adhere to the above standards, although they may be other wise acceptable, will be rejected or returned to authors for correction. Proofs and Reprints — Proofs should be corrected and returned as soon as received, with an abstract on the form provided. All changes in proof, except printers and editorial er rors, will be charged to authors. Reprints may be purchased by contributors. A statement of the cost of reprints and an order form will be sent with the proof. Abstract — An abstract not longer than 3% of the paper should accompany each regular article following the title page. It eliminates the need for a summary. Page Charges — All regular papers will be charged at the rate of $18.00 per printed page. These charges are in addition to reprints. Papers in excess of 10 printed pages may be charged full cost of publication for the excess pages (about $25.00 per page). Member authors who are retired or not affiliated with an institution may request to have page charges waived. Acceptance of papers will be based solely on their scientific merit, without regard to the author's financial support. PROCEEDINGS of the Hawaiian Entomological Society VOL XXIIL NO. 3 FOR THE YEAR 1978 FEBRUARY^^g! JANUARY The 865th meeting of the Hawaiian Entomological Society was called to order by President Ikeda at 2:05 p.m., January 9, 1978, in the Conference Room, Bishop Museum Members Present: Bianchi, B. Brennan, Goff, Higa, Howarth, Ikeda, Joyce, Look, Nishida, Papp, Riotte, Sherman, Steffan, Sugerman, Tenorio. Visitors: Ralph Stoaks, John B. Steinweden. Business: It was moved and passed that the wives and spouses be recog nized as guests for purposes of the Society minutes. Pres. Ikeda announced that names of the Standing Committees for 1978 will be available at the next meeting. Wally Steffan, chairman of the Science Fair Committee, moved that the Society provide a $25 award for the best entomological exhibit displayed at the fair. The motion was approved. Notes and Exhibitions Cothonaspis n. sp.: A number of this recently introduced leafminer parasite (Cynipidae) from Texas (R. Burkhart, June 1976) was recovered from leafminer infested tomato and cucumber plants from Waimanalo, Mikilua and Waianae during surveys conducted in June, September and October 1977. In 1977 about 60,000 adult parasites were released on Oahu. S. Higa. Chrysonotomyia (Achrysochareila) agromyzae (Crawford): Large numbers of this leafminer parasite (Eulophidae) introduced from Linares, Mexico by R. Burkhart in June 1976 were recovered from tomato and cucumber plants at Mikilua and Waianae by P. D. Mothershead during September and October 1977. A single release of this parasite was made in Lualualei in May 1977. This parasite along with a closely related species, C. punctivenths (Crawford), were introduced and released in 1977 under the generic name Achrysochareila. According to C. M. Yoshimoto, Canada Dept. of Agriculture, Z. Boucek, Chalcidolpgist with the Commonwealth Institute of Entomology, British Museum (Natural History), London, has reviewed the group and has concluded that Achrysochareila Girault is a subgenus of Chrysonotomyia Ashmead, a discovery of an earlier name, thus the new combination. S. Higa Antrocephalus sp.: One male specimen of this chalcid wasp was col lected for the first time from the island of Hawaii, at Wailea near Hilo, by S. Matayoshi on October 24, 1977, a new island record. It was previously identified and reported by Dr. J. W. Beardsley from Oahu in 1974 (Proc. Haw. Ent. Soc. Vol. 22 (2): 164). This insect, probably a parasite of lepidop- terous pupae, is quite distinct from A. pertorvus (Girault) which has been in Hawaii for many years. S. Higa. 310 Proceedings, Hawaiian Entomological Society Psilogramma menephron (Cramer): Two larvae of the gray hawk moth were collected from African olive (Olea africana) on November 10, 1977 at Salt Lake, Oahu by J. Kajiwara. Identification was made by Father J. C. E. Riotte, Bishop Museum. According to Bell and Scott (The Fauna of British India, Vol. V, June 1937) its distribution is "Throughout the Indian sub-region, China, and eastward to the Solomon Islands. Widely distributed and locally common, in both forests and open country, up to 6,000' elevation". Dupont and Roepke (Heterocera Javanica, 1941) also list Japan through S. E. Asia, the Archipelago, N. Australia, and New Caledonia. Host plants in both volumes and F. G. Browne's (Pest and Dis eases of Forest Plantation Trees, 1968) include Casuarina spp. (Casuarinaceae); Melia azedarach (Meliaceae); Pangium edule (Flacour- tiaceae); Orxylum indicum and Apathodea campanulata (Bignoniaceae); Olea dioicum, Jasminum, Ligustrumand Nyctanthes arbor-tristis (Oleaceae); and Tectona grandis, Clerodendron infortunatum, C. villosum, Vitex negundo, Callicarpa arborea, and Gmelina arborea (Verbenaceae). All genera are represented in Hawaii as forest and shade trees or ornamentals, including the commercially grown pikake. S. Higa. Parasitization of Tenodera angustipennis Saussure: An ootheca of the mantid Tenodera angustipennis Saussure was collected by K. Adee (U. S. Forest Service) on an African tulip tree, Spathodea campanulata Beauv., on October 17,1977 in Hilo, Hawaii. On October 21, torymid wasps subse quently identified as Podagrion mantis (Ashmead) began emerging from the ootheca. By October 31, 40 mantids had emerged from the ootheca. Parasites, however, continued to emerge until November 28, reaching a total of 13 males and 56 females (sex ratio 1:4.3). Tenodera angustipennis is a native of China, Japan and Java, and was first reported from the island of Hawaii in 1900 (Perkins, Fauna Hawaiien- sis, David Sharp, ed., Cambridge Univ. Press, 2(6):687-690). Zimmer man (1948, Insects of Hawaii, Vol 2, Univ. Hawaii Press, 475pp) lists Podagrion mantis as a parasite of T. angustipennis, but gives no details on its biology. Both species were identified by F. G. Howarth of the Bishop Mu seum. R. P. Papp. Observations on the Cerambycid Plagithmysus varians Sharp in its host Acacia koa Gray: On August 1, 1977,1 examined several large koa logs (Acacia koa Gray) in the Blair Ltd. lumberyard in Hilo, Hawaii. The logs had recently been removed from logging area above Laupahoehoe at an elevation of 1646 m. On July 29 Mr. Nelson Kunitake of the Hawaii State Division of Forestry had noticed many beetle larvae under the bark of the logs, and had brought specimens to me. Upon examining the logs I found that much of the bark had unfor tunately been damaged or destroyed in the logging operation. With the help of two employees at the yard, we were able to remove several intact sections of bark. In the cambium beneath one section measuring 36 x 51 cm2, 68 cerambycid larvae were counted (1 larva per 27 cm2 of log suface). A large number of abortive larval galleries was also uncovered, but since they continually crossed and recrossed each other, an accurate estimate of the total number was precluded.
