disappeared during the past ten years and endemic malaria is

Fernale. Length 5 to 6 mm.; wing 5 mm. Proboscis slender, dark
brown to black. Palpi as long as the proboscis, clothed with ap-
pressed brown to black scales. Occiput black; densely clothed with
erect, triangular, slightly-notched scales, black at the sides and be-
hind, a white patch in the middle. Mesonotum with a broad grayish
median stripe, the sides brown; vestiture of short yellowish-white
hairs. Pleurae brownish intermingled with pale areas. Abdomen
brown, the median area darker, clothed with numerous short yellowish
hairs. Wing scales black, forming distinct spots as shown in figure
1, Pl. VIII. Fringe at apex of wing with a distinct light yellow
to coppery spot. Legs black, with a slight bluish lustre; apices of
femora and tibiae narrowly yellowish white.
Male hypopygiuna. (Fig. 1, Pl. IX.) Side-piece at least one
and one-half times as long as wide, somewhat conical. Internal
spine located slightly beyond the middle. Basal spines, two, large;
outer spine longer and tapering to a fine point; inner spine broad,
recurved to tip. Claspers longer than the side-piece, narrowed
medianly. Claspette bilobed, almost reaching the apex of mesosome;
dorsal lobe small with two or three equal, pointed spines, not fused;
ventral lobe larger with three spiries. Mesosome long and narrow;
leaflets three pairs, the dorsal pair much larger. Ninth tergite con-
sists of a narrow band of chitin with two narrow, bluntly pointed,
lateral processes, reaching nearly to apex of mesosome.
Larva. The larva is almost identical with that of pzuzctipemzk.
The characters indicated in the key have proved the most satisfactory
for distinguishing the two species.
This species is widely distributed throughout the western
United States, British Columbia, Yukon, and eastward through
