AEDES (HETERONYCHA) THELCTER Dyar. 
Aédes (Taeniorhynchus?) theleter DyaR, Ins. Ins. Mens., vol. 6, p. 129, 
1918. 
A medium-sized mosquito. Mesonotum entirely dull yellowish 
scaled, the scaling coarse and thick; head similarly clothed. Abdo- 
men black, with triangular basal segmental median and lateral whit- 
ish patches; venter pale. Legs black, the femora pale below, the 
tibiae and first tarsal joint also more or less pale on the under side. 
Wing scales all dark. Proboscis black. 
The larva has not been found; but the adults occur after heavy 
rains with other species of similar habit, and the breeding is doubt- 
less in temporary ground pools. 
Habitat.—Southern Texas.

AEDES (HETERONYCHA) AURIFER Coauiilett. 
Culex aurifer CoquiLtert, Can. Ent., vol. 35, p. 255, 1908. 
A medium-sized or rather large brown-black mosquito. Head 
golden scaled in the middle and sides, dark brown between. Meso- 
notum with a very broad median deep blackish brown stripe, leaving 
the sides narrowly golden yellow. Abdomen black dorsally, with 
elongate triangular white basal segmental lateral spots; venter mostly 
whitish. Legs deep black, the femora broadly white below except at 
the tips. Wing scales narrow, black. 
The larvae live in early spring pools, particularly cranberry bogs, 
hatching from overwintering eggs. The attack of the adult is de- 
scribed as bloodthirsty. The mating habits of the males are un- 
known. The species is local and rare. 
Distribution—Southern Canada to New Jersey; Minnesota.
