Additional costs to the Society for correction of authors' changes in proofs may be charged to the authors. An order for reprints should be placed when proofs are returned. Fifty gratis copies of reprints will be supplied by the Society to'authors under certain circumstances. Examination of articles in this issue will help in conforming to the style of presentation desired. Many helpful hints are found in Style Manual for Biological Journals prepared by the Committee on Forms and Style of the Conference of Biological Editors available from the American Institute of Biological Sciences, 3900 Wisconsin Avenue N.

Dr. Tamashiro made a motion that a sum not to exceed $100.0 be approved for this project to be done by University of Hawaii graduate students. Motion was seconded by A. Thistle and unanimously approved. Notes and Exhibitions Dr. Gressitt exhibited 4 current issues of Pacific Insect Monographs, 3 of which were of interest to Hawaii. Hister nomas Erichson and Pachylister caffer Erichson: Miss Mabel Chong reported that these two histerid beetles which are predaceous on horn fly larvae were found in goodly numbers at Makena, Maui, in November 1967 by Nobuo Miyahira. These constitute new island records for these two beneficial insects. Previously, P. caffer was found established only on the island of Hawaii and H. nomas only on Oahu and Hawaii. The specimens were determined by Dr. W. Wenzel of the Field Museum of Natural History, Chicago. Parasites of Herpetogramma licarsisalis (Walker): Parasites from larval and pupal material of Herpetogramma licarsisalis (Walker) col lected from Kualoa Ranch, Oahu, which were reported at the Society meeting of 9 October 1967, have been identified by the Insect Identification and Parasite Introduction Research Branch, Beltsville, Maryland, as Trichogramma semifumatum (Perkins), Eucelatoria armigera (Coq.), Casinaria infesta (Cress.), Cremastus (Trathala) flavo-orbitalis (Cam.) and Meteorus sp. possibly laphygmae Vier. Last month these same parasites were found in great numbers at the Koa Ridge Ranch, Kipapa, Oahu. Dendrosoter protuberans Nees: A shipment of D. protuberans, a braconid parasite of the elm bark beetle was received from Bruce H. Kennedy of the U.S.D.A. Forest Service, Delaware, Ohio. Part of the shipment was retained for propagation on our black twig borer (Xylosandrus compactus) while portions of it were released at Honouliuli Forest Reserve and at lower Tantalus where the borers are plentiful. Program: President Bianchi presented a very interesting talk, illustrated with slides, on his last trip to Brazil and Guatemala. February The 746th meeting of the Hawaiian Entomological Society was called to order by President Bianchi at 2:00 pm, 13 February 1968, in Agee Hall, HSPA Experiment Station. Members Present: Au, Barrett, Bess, Bianchi, Carter, Chong, Davis, Drake, Fluker, Gressitt, Haramoto, Hart, Joyce, Keenan, LaPlante, Look, Maa, Mau, Nakao, Nakata, Namba, Olson, Park, Pemberton, Shiroma, Vol. XX, No. 2, August, 1969 261 Spencer, Sugerman, Tamashiro, Van Zwaluwenburg, Woolford, and Yoshioka. Visitors Present: Richard Bovard, James Hiramoto, John McDonald, Banpot Napompeth, and Henry van der Schalie. Election of New Members: Eugene, Drake, George D. Peterson, and Salman Wasti were unanimously elected to membership. Announcements: President Bianchi announced the death of Miss Amy Suehiro, who passed away on the 20th of January, 1968. Miss Suehiro was a long time member and contributed much to the Society, both as an officer and as the editor of the Proceedings. Dr. Gressitt announced that the Bishop Museum will set up a Memorial Fund in Miss Suehiro's honor. This Fund will be used as grants for the study of Hawaiian Entomology. All interested to help initiate this Me morial Fund were asked to contact Dr. Gressit. Notes and Exhibitions Trissolcus sp.: Early in January 1968, Wendell Au, student as sistant of the Insectary Section, State Department of Agriculture, observed some "off color" black stink bug eggs in the old quarry area of the Univer sity of Hawaii campus. These were collected and held for emergence and, in due course produced scelionid parasites. These parasites were identifi ed as Trissolcus sp. by P. M. Marsh, U.S.D.A. taxonomist in Washington. This is the first record of a plataspid egg parasite in Hawaii. Sub sequently, Trissolcus was reared from C. xanthogramma eggs collected in Hilo by S.D.A. staff members in February 1968, a new Island record. Preliminary studies by Insectary Supervisor, Sung Hin Au, indicate that Trissolcus begins ovipositing on the day of emergence. Initially eggs are reddish and after 5 days, parasitized eggs in successive changes be come brown, gray and finally, black. Eleven days after darkening, adults emerge. The total parasite life cycle, from egg to adult is 16 days and adult longevity ranges from 4 to 10 days. The host, Coptosoma requires 48-52 days to develop from egg to adult and so it is possible for 3 generations of Trissolcus to develop during one generation of C. xanthogramma. In addition to the old quarry at the University of Hawaii and Hilo, Hawaii, Trissolcus has been reared from eggs collected at Aiea, Waimanalo, and at the Coconut Island boat landing, windward Oahu. Mitchell, Davis, and Funasaki, on 7 October 1966, at the Coconut Island boat landing observed a Coptosoma population of 1,000 adults and nymphs per 4 feet of branch on Sesbania. On 8 February 1968, Au and Wong found more than 25 adults and nymphs per 4 feet of branch. Of 221 egg clusters collected, 210 or 95% were parasitized. At Aiea, of 122 clusters of eggs collected on 6 February on pigeon 262 Proceedings, Hawaiian Entomological Society pea, 93 or 76% were parasitized and at the old quarry, University of Hawaii, in two collections on mauna-loa vine totaling 170 egg clusters made on 19 and 31 January 1968, 40 or 36% were parasitized. According to P. M. Marsh, 'This parasite probably came in with its host from the Philippine Islands. The following species of Trissolcus have been reared from Coptosoma cribaria: T. latisulcus (in the Philippines and India), and T. tetartus (in India and Sumatra); from Coptosoma punctis- simum: T. minor (in Japan). Your specimens are not any of the above species." Araeocorynus cumingi Jekel: On 18 January 1968, mauna-loa seeds near the Kauai Surf Hotel, Nawiliwili, were found heavily infested by the anthribid, A. cumingi Jekel by Davis and Bianchi.
