differing antennal characteristics. Taxonomically, the most closely related species appears 
to be Hybomitra rupestris which has never been reported as collected in California. Slight 
colorational and antennal differences also separate our specimen from this species, but for 
the time being, the specimen will be termed Hybomitra species near rupestris, until 
further bait trapping studies can be conducted in the Sierras in the summer of 1979.—Susan

A New Distribution and Habitat Record for Anuroctonus phaiodactylus 
(Wood) (Scorpionida: Vaejovidae) 
Anuroctonus phaiodactylus is a common species of scorpion found in the coastal areas of 
southern California. Both males and females live in a permanently constructed burrow 
throughout their life cycle. Because of the burrowing activity these scorpions are found in 
hard packed soils. 
In September 1977, while blacklighting at night, two male A. phaiodactylus were ob¬ 
served on the ground surface on Yucca Valley (San Bernardino County), California. This 
observation is noteworthy for two reasons; 1) It represents a new distribution record for the 
species, the closest previous record being San Bernardino (Pocock 1902, Scorpions 
Pedipalpi and Solfugae) and 2) It also represents an unusual habitat record for the species 
in that the males were found on an unstabilized sandy substrate. This type of soil is 
inconsistent with the scorpion’s burrowing activity. Although it is very unusual to find A. 
phaiodactylus on the surface, males will emerge and migrate in search of females during 
the mating season.—M. L. Swoveland San Francisco State University. 
The main speaker of the evening was Dr. Martin C. Birch, University of California, 
Davis. His program entitled “Chemical Communication in Bark Beetles,” was well 
received by members and guests present. 
Refreshments were served in the Trustee’s room following the meeting.— L. G. Bezark, 
Secretary. 
THREE HUNDRED AND EIGHTY-NINTH MEETING 
The 389th meeting was held 17 November 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 26 members and 10 guests present. 
The minutes of the meeting held 20 October 1978 were summarized. The auditing 
committee reported and the treasurer summarized the year; Paul Arnaud, Jr. stated that the 
treasurer’s office is indebted to Mrs. V. Hawley (as volunteer) and Mrs. Gail Freihofer 
(Entomology Secretary) for their handling of the Society’s accounts, billings, and mailing of 
publications, and to our member Mr. H. Vannoy Davis of Walnut Creek, California, not 
only for his audit of the Treasurer’s records, but also for his completion of the Society’s 
state and federal tax forms. The nominating committee brought forth the following names 
for office in 1979: President-elect Marius Wasbauer, Secretary Larry Bezark, and Treasurer 
Paul Arnaud, Jr. 
The following persons were elected to membership in the Society, regular members: 
Gary L. Piper, T. A. West, Dr. W. G. litis; student members: Susan B. Opp, Susanne 
Muzzio, Andrew Coblentz, Harvey Ito, Lee Guidry. 
Howell Daly reported on the death of Herbert H. Ross. Dr. Cornelius Philip discussed 
Tabanus biguttatus, the larvae of which form a plug to withstand the drying and 
cracking of surrounding mud. 
The gavel was handed over to the new president, John Doyen, who introduced Dr. 
John Anderson and the presidential address entitled “The Biology and Behavior of Nose 
Bot Flies of California Black-tailed Deer.” Refreshments were served in the Trustee’s 
room following the meeting.— L. G. Bezark, Secretary.
