HELEOMYZID FLIES NORTH OF MBXICO—GILL 575 
bristle, longer hairs ventrally between the coxae; remainder of pleura 
bare. 
Legs dark rusty brown, becoming lighter distally; femora may have 
faint grayish pollinosity; middle tibiae with several ventral apical 
bristles. 
Wings hyaline, costal spines distinct. 
Abdomen dark brown with faint grayish pollinosity; scattered 
setae, segments 2—5 with bristles along posterior margins; terminalia 
concolorous with remainder of abdomen. 
FremaLe.—I am not able to distinguish the females of A. aldrichi 
(Garrett) from those of A. czernyi Garrett. Females taken on the 
same date and from the same locality as the A. aldrichi (Garrett) male 
are similar in appearance to the male. Cheek-eye ratio from 0.35 to 
0.42. 
Distripution.—The species was described from British Columbia 
(March). I have examined undetermined Anypotacta females from 
Alaska (April) and California (May). 
Briotocy.—The female collected in Alaska was collected on human 
excrement. No other data on the biology of Anypotacta are known. 
Remarxs.—The illustration of the male terminalia was drawn from 
the extended terminalia of the holotype. The terminalia were not 
removed from the specimen and cleared, but the bilobed structure of 
the surstyli is sufficient to distinguish this species from A. czernyi 
Garrett. 
Anypotacta czernyi Garrett, new species 
Fiaure 71 
In the Garrett collection I found a series of type specimens labelled 
Anypotacta czernyi Garrett. The holotype (male) was from Jemez 
Springs, N. Mex., 9 July? 1914 (month not clear, but appeared to be 
“Jl”), J. Westgate. The allotype had the same collection data. One 
male paratype had the same data as the holotype and allotype. Two 
male paratypes had the same data, except that they were collected 
July 26. There are specimens in the U.S. National Museum collected 
from caves in Nevada during July and August. 
I find no record of Garrett’s having published a description of 
Anypotacta czernyi. The only ‘“czernyi” he described was Postleria 
czerny? (1925a, p. 2.); however, the description does not fit the types 
of Anypotacta czernyi, and the localities also differ. 
I can find no reliable character for separating A. aldrichi (Garrett) 
from this species other than the structure of the male terminalia. 
The above description of A. aldrichi (Garrett) thus applies also to A. 
ezernyt Garrett. As previously mentioned, I cannot separate the 
females of the two species.
