The male of this species is very similar to the preceding, except 
that the fourth tarsal segment of the hind leg is less than twice as 
long as wide, the cheek is narrower (cheek-eye ratio from 0.35 to 0.45), 
the epandrium has two protruding “‘knobs,” and there are 3 or 4 stout 
spines on the ventral edge of the hypandrium. The female is quite 
distinct from all other known species, having a thick patch of short 
hairs on each side of the third abdominal tergite. 
DistTrRIBUTION.—British Columbia, California, Arizona, Utah 
(Knowlton and others, 1939), Texas, Minnesota, Iowa, Missouri, Georgia, 
South Carolina, Ohio, District of Columbia; March—August, 
December. 
Remarks.—Tonnoir and Malloch (1927) synonymize Leria placata 
Hutton with P. pectinata (Loew). In view of the fact that such a 
decision necessitates an examination of the male terminalia of Hutton’s 
type, I have not listed the synonymy here. Hutton (1901, p. 82) 
described the species as having the eye ‘‘small.’”’ This description 
casts further doubt on the synonymy with P. pectinata (Loew). 
Although P. pectinata (Loew) was reported by Howard (1901) from 
human excrement, the specimens (in USNM) on which the record is 
based are females and do not appear to be of this species.

The fourth tarsal segment of the hind leg of the male is very short 
in this species, and is usually no longer than it is broad. The epan- 
drium of the male postabdomen is turned under ventrally, and the 
distal edge is rather truncate and rounded at the anterior and pos- 
terior corners. The very dark forefemora is a useful supplemental 
character in identifying both sexes of this species. 
MALE AND FEMALE.—Front yellowish brown, darker toward the 
vertex; frontal plates, ocellar triangle, and back of head grayish 
pollinose; antennae dark brown; remainder of head dirty yellow; 
buccal setae in 1 or 2 irregular rows; cheek-eye ratio from 0.4 to 0.55. 
Thorax ash gray, pollinose, sometimes brownish along edge of 
sclerites; mesonotum usually with a median brown vitta which extends
