brown, with grayish pollinosity; epandrium of male relatively narrow, 
the length about 3 times the greatest width, as seen in lateral view. 
LrenetH.—4.0—-5.0 mm. 
DistriputTion.—Oregon, Idaho, California, Arizona, Texas, Colo- 
rado, Wyoming, Alberta, Saskatchewan, South Dakota, Nebraska, 
Iowa, Michigan, Ohio, Manitoba, Ontario, Tennessee, North Carolina, 
Maryland, New Jersey, New York; collected throughout the year. 
Brotoacy.—Adults have been reared from larvae found in pigeon 
feces and in the nests of bank swallows (specimens in USNM), and 
have been reared from pupae from the nest of Microtus (specimens in 
the Canadian National Collection). Also in the latter collection is 
a specimen taken at the entrance to a burrow of Cynomys. 
Pseudoleria intermedia Garrett

Pseudoleria intermedia Garrett, 1925b, p. 3. 
This species can best be separated from the preceding species by 
the shape of the epandrium of the male postabdomen. However, 
the general coloration of this species appears to be somewhat darker 
than that of Pseudoleria crassata Garrett. The thorax and abdomen 
are usually ash gray, with brownish pleura and brownish mesonotal 
vittae similar to those described for P. crassata Garrett. The femora 
of the legs are dark brown to ash gray, with a grayish pollinosity, 
especially on the forefemora. The epandrium of the male postabdomen 
is about twice as long as its greatest width, when seen in lateral view. 
The first longitudinal vein (R,) of P. intermedia Garrett is described 
by Garrett as being short, with the tip proximad of the small (ante- 
rior) crossvein. Although the tip does lie proximad of the small 
crossvein, this character is also found in related species and is 
therefore not a useful key character. 
I have examined the type (a male) and 2 other male specimens 
determined by Garrett. 
LrenetH.—3.5-5.0 mm.

I examined the type male of Pseudoleria media Garrett, but could 
find no means of distinguishing it from P. intermedia Garrett. The 
slide preparation of the terminalia is in such poor condition that I
