ratio is from 0.59 to 0.67. The species is further described in Curran 
(1933). It was described from a holotype and three paratypes (all 
males) from Carbon County, Wyo. 
DistRiBUTION.—Wyoming, Colorado, Nebraska; June, September. 
Anorostoma longipile, new species 
Ficure 50 
This species is very similar to A. carbona Curran, but the long 
silky hairs in certain areas of the body of the male of A. longipile, 
new species, will readily distinguish it. The shape of the surstylus 
differs slightly in the two species. The entire type series, which was 
collected at Arnold Ranch, Pecos, N. Mex., 3 Sept. 1909, by J. D. 
Mitchell, was deposited in the collection of the U.S. National Muse- 
um. I have seen no specimens other than the type series. 
Maur.—Head as in carbona and related species; thorax yellowish 
orange to yellowish brown, with grayish pollinosity; mesonotum 
darker than pleura; mesonotal setae very sparse; sternopleuron with a 
single row of hairs down the middle, in addition to the usual bristle. 
Forecoxae with long hairs hanging down posteriorly, resembling a 
beard; all legs with long fine hairs in addition to the usual bristles; 
the ventral hairs of the middle tibiae are about as long as the dorsal 
preapical bristle; the hind basitarsus is thickened and about equal to 
(or very slightly longer than) the length of the following segment. 
Wings with brownish tinge and with the crossveins slightly clouded 
with brown. 
Abdomen black or dark brown in ground color with grayish pol- 
linosity; postabdomen yellowish orange; hairs of epandrium as long 
as the length of the surstylus. 
FrMALE.—Similar to male, except lacking the long hairs; hind 
basitarsus longer than the following segment and not thickened; 
terminal abdominal spines strong, as in A. jersei Garrett. 
Lenetu.—4.0—5.5 mm. 
Typrs.—The holotype male, allotype, 1 paratype male, and 3 
paratype females have been deposited in the U.S. National Museum 
(USNM 65443); 1 paratype of each sex has been deposited in the 
collection of the State College of Washington. 
Anorostoma fumipenne, new species 
Ficure 51 
The smoky clouding of the wings, the evidence of dark mesonotal 
vittae, and the shape of the epiphallic process distinguish the male of 
this species.
