1924] New Caly pirate Dipter a from New England 195 
Scatophaga monticola sp. nov. 
Male. — Similar to furcata Say in color, the third antennal 
segment fuscous, palpi yellow; dorsum of thorax with four pale 
brown vittse; apices of abdominal tergites narrowly black; legs 
yellow, fore femora with a darker stripe on posterodorsal surface; 
wing veins clouded, the apices of veins 2, 3, and 4 rather faintly 
so, both cross-veins with spot-like clouds. 
Arista bare; palpi dilated. Thorax with 2 + 3 dorsocentral 
bristles which are very distinct because of their strength and the 
scarcity of dorsal hairs; pteropleura and hypopleura bare. Pro- 
cesses of fifth sternite long, tapered to a rounded point, their 
basal width less than half as great as their length, no short 
spines evident. All femora and tibia3 with rather dense erect 
ventral hairs the length of which does not noticeably exceed the 
diameter of the parts upon which they are situated; fore tibia 
with two anterodorsal and one fine posterior bristle: mid and 
hind femora without distinct ventral bristles; mid tibia with 
two or three anterodorsal and posterodorsal bristles; hind tibia 
with three anterodorsal and posterodorsal bristles, the ante- 
ro ventral bristles usually indistinguishable. 
Female. — Similar to the male in color but slightly darker. 
Abdomen pointed. Legs less hairy, the hind femora usually 
with one or two anteroventral bristles apically. 
Length, 7 mm. 
Type, male, allotype, and one female paratype, Mt. Wash- 
ington, N. H. 
The fifth sternite in male is similar to Figure 22, pi. 14, in 
my paper on the Pribilof Island Dipteray which is unfortunately 
mislabeled furcata instead of islandica and so referred to in the 
text. Figure 21 represents the fifth sternite in furcata. 
The description herein presented is drawn from specimens 
in the U. S. National Museum collected by Mrs. A. T. Slosson 
and labeled S. hicolor Walker. I am confident that Walker’s 
species is a synonym of furcata Say. These specimens were 
brought to my attention by Dr. J. M. Aldrich. The bare arista,
