to be made of fecal materials (Boving and Craighead 1931), and were under 5 mm in length, 
about 4 times longer than wide, and with longitudinal, slightly spiraling broken ribs 
composed of 3 to 5 serially spaced ridges. The posterior end was rounded and closed, 
whereas the anterior end was flat but filled by the round flat head and legs of a larva. 
The larvae key to the couplet delineating the chrysomelid subfamilies Cryptocephalinae 
and Lamprosominae. The latter contains only one California species, and this has not been 
taken at the San Joaquin Experimental Range. Of the Cryptocephalinae, 3 adults of Pachy- 
brachys punctatus Bowditch were taken in September 1972 from the area to be sampled. 
No adults were taken in the quick traps. 
The larvae were taken on only 5 of the 22 sample dates, and the totals per date were 2 
(March 13, 1973), 4 (November 30, 1973), 1 (January 11, 1974), 5 (February 12, 1974) and 2 
(March 14, 1974). With 16 samples being taken on each date the highest population on the 
open rolling slopes was equal to 0.63/M 2 .—Craig Hasegawa and Donald Burdick. 
The main speaker of the evening was Dr. Bernard C. Nelson, Public Health Biologist, 
Vector and Waste Management Section, California Department of Health, Berkeley. His 
discussion of bubonic plague in California was informative and well received by those in 
attendance. 
Refreshments were served in the Trustee’s room following the meeting.— L. G. Bezark, 
Secretary. 
THREE HUNDRED AND EIGHTY-SEVENTH MEETING 
The 387th meeting was the Annual Picnic, held at Del Valle Regional Park. Insect 
collecting and photography were enjoyed by the six stalwarts who attended. 
THREE HUNDRED AND EIGHTY-EIGHTH MEETING 
The 388th meeting was held 20 October 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 22 members and 20 guests in attendance. 
The minutes of the meeting held 21 April 1978, and the Picnic held in May were 
summarized. 
The following members were elected to the Society, regular member: Marilyn Vernon; 
student members: Heidi Dobson, Randall Boquist, Leonard Vincent, Gary Trimble, Ken 
Weiner, Steven Abe. 
Harriet Reinhard showed slides of Calosaturnia mendocino, the larvae of which feed on 
Manzanita. J. Gordon Edwards, San Jose State University, described a project sending 
larvae of the Gypsy Moth to Pennsylvania for host preference studies. Among others, 
Eucalyptus, Coast Redwood and Giant Sequoia are hosts readily eaten by the larvae. 
The following notes were given. 
A Possible New Species of Genus Hybomitra Found in California 
(Diptera: Tabanidae) 
During late August, 1978, a single specimen of Hybomitra species was collected from a 
baited flight trap in Sierra County, California, by Maury Swoveland. The specific location 
of capture was Camp Leonard, San Francisco State University Sierra Nevada Field 
Campus on highway 49, six miles southwest of Sierra City. A malaise flight trap was baited 
with a black ball in an attempt to collect Tabanidae specimens for a field study project that 
was being conducted by Susan Opp, an Entomology student at San Francisco State 
University. 
The specimen is thought to be a possible new species of Hybomitra by both Dr. 
Cornelius B. Philip, CAS, and Dr. Robert Lane, California Department of Public Health, 
Berkeley. The specimen differs from the three specimens of Hybomitra rhombica 
collected in the same area earlier in the summer due to a reddish abdominal coloration and
