Oahu. Those not noted above as endemics are widespread immigrants known from either 
the Pacific, Asia or North America. Robert L. Langston, Kensington, California. 
The main speaker of the evening was Ms. Deborah Green, University of California, 
Berkeley. Her multi-media presentation, “Insect-Plant Coevolution,” was enjoyed by 
all. 
Refreshments were served in the Trustee’s room following the meeting.— L. G. Bezark, 
Secretary. 
THREE HUNDRED AND EIGHTY-FIFTH MEETING 
The 385th meeting was held 17 March 1978 at 8:00 p.m. in the Morrison Auditorium of 
the California Academy of Sciences, Golden Gate Park, San Francisco, with President 
Anderson presiding, and 17 members and 8 guests present. 
The minutes of the meeting held 17 February 1978 were summarized. Larry Bezark, 
San Jose State University, discussed a partially duplicated antenna of Tetraopes discoideus 
LeConte. Dr. J. A. Powell, University of California, Berkeley, presented the following 
note: Grapholitha edwardsiana (Kraft, 1907) (Tortricidae): an endemic San Francisco 
moth nearing extinction. —Kodachrome slides were exhibited showing adults, larvae and 
the habitat of this species, which was described from specimens in the Henry Edwards 
collection (“Cal.”, “S. Fran., Cal.”). It remained an enigma for more than half a century. A 
colony was discovered at the Presidio near Baker Beach in 1961, but that habitat was later 
destroyed. Adults fly in late April and May in association with Lupinus arboreus, and 
larvae feed inside the floral stalks. Lupinus chamissonis, which has short floral stalks, is not 
used, even where the two lupines grow interspersed. Because L. arboreus was one of the 
dominant plants of the S.F. sand hills, G. edwardsiana probably occurred extensively over 
the western part of the peninsula prior to urbanization. Survey during the past year 
revealed three colonies: two on parklands, the larger on bluffs north of Baker Beach, the 
other near the southeast end of Lake Merced; the third colony is partly on municipal 
property, in Daly City at the mouth of Guadelupe Canyon above John F. Kennedy school, 
recent construction of which probably destroyed most of the hostplant colony. Information 
regarding occurrence of L. arboreus at other sites on the peninsula is solicited. 
The main speaker of the evening was Dr. A. H. Purcell, University of California, 
Berkeley. His presentation entitled “Of leafhoppers and wine: Sharpshooters and the 
mysterious vine disease in California,” was enjoyed by all. 
Refreshments were served in the Trustee’s room following the meeting.— L. G. Bezark,

THREE HUNDRED AND EIGHTY-SIXTH MEETING 
The 386th meeting was held 21 April 1978 at 8:00 p.m. in the Morrison Auditorium of the 
California Academy of Sciences, Golden Gate Park, San Francisco, with 31 members and 
24 guests in attendance. 
The minutes of the meeting held 17 March 1978 were summarized. 
The following persons were elected to membership in the Society, regular members: Dr. 
Robert F. Rockwell, Dr. Peter Maddison; student members: Ann E. Hajek, Jose A. Mari 
Mutt, Roger K. Shimer. 
Dr. E. L. Smith reported on progress relating to morphological studies of living and 
extinct insect groups, and discussed features of the labrum. The following note was given: 
Case making chrysomelid larvae from the California annual grassland.—During a study 
of the California annual grassland (IBP), 14 small, cylindrical brown cases were found 
in 80 0.5M 2 samples covering five separate dates. The samples were taken with a quick 
trap, and the arthropods from both the clipped grass and the vacuumed litter were 
extracted by means of a Tullgren funnel. The brown cases had the appearance of mud, said
