lowish, bristles and hairs shorter than in male. Face deeply 
recessed; occiput of both sexes blackish, nearly bare behind the 
orbital fringe; antennae short, the arista arising from the base 
of the deflected reniform third joint; proboscis short and fleshy,

what smoky, stigma darker, base in female paler than in male,

The genus Gloma is remarkable in the Empididae in having 
the arista truly dorsal on the small stubby reniform third joint. 
The South American Hyperperacera Collin, which also has a 
dorsal arista, has bristly metapleurae. 
The species of Gloma are rarely encountered, and occur in 
the forests of the Pacific North-west. But three species exist in 
the American fauna, the earlier references to Gloma pertaining 
to Oreogeton, with Gloma phthia Walker belonging in Syneches. 
Gloma pectinipes, n.sp. 
Length 4 mm. Similar to the preceding species, but larger 
and with the hairs and bristles abundant and prominent. Lower 
occipital hairs numerous. Thorax thinly overlaid with cinereous 
pollen, a fuscous point on the humeri. Abdomen subshining. 
Fringe of the hind tibiae with about twenty hairs. Wings some- 
what smoky, stigma darker, veins piceous, alulae dusky; halteres 
black. The distinctive characters are given in the following 
table.
