Stein, female. The record of the occurrence of bispinosa in 
North America requires confirmation. The female of cressoni 
Malloch is unknown. 
I have included scambus Zetterstedt in the key, basing the rec- 
ord upon a female specimen taken at Grant, Colorado, July 13, 
1916 (E. C. Jackson). | 
The male of this species was not included in my key to this 
seX in a previous paper in this Buttetrin,* as I did not then 
know of its occurrence in this country. The male will run down 
to caption 3 in that key and may be separated from occulta by 
the bare eyes and from both occulta and acuta, the two species in 
the caption, by the curved hind femora and by the tibiz, the 
latter being thin to about the middle and then suddenly thick- 
ened, with a strong apically curved thorn at the beginning of the 
thickened part, and the anterior surface furnished with a series 
of long bristly hairs. 
This species is rare in Europe and not heretofore recorded from. 
North Amercia. Although I have seen only the female, the 
species is so characteristic that there is little doubt as to its 
identity. t 
It may be of interest to record the occurrence of militaris 
Meigen in British Columbia. This European species was re- 
corded by Stein from the eastern states. 
The females of this genus may be separated from those of 
Phaontinee by the following combination of characters: Frons 
broad, occupying at least one third the head-width; orbits more 
or less glossy, well differentiated, with at least the anterior supra- 
orbital bristle directed forward (except in my specimen of cili- 
ata) ; interfrontal cruciate bristles well developed; cheeks almost 
linear; mesonotum with 4 pairs of postsutural dorso-centrals ; 
sternopleura with 2 bristles (1:1); apical abdominal segment 
without thorns; legs with few bristles; sixth vein incomplete. 
The most closely related genera so far known to occur in this 
country are Ophyra and Pogonomyia. ‘The latter has conspicu- 
ously bristled tibize and much sttonger prealer bristle; the former 
has the ocellar triangle carried well beyond the cruciate bristles
