Lilia bs MOSQUITOES OF THE UNITED STATES—DYAR. 85 
Subgenus TAENIORHYNCHUS Lynch Arribalzaga.'® 
AEDES (TAENIORHYNCHUS) ATROPALPUS Coguillett. 
Culex atropalpus CoquiteTtT, Can. Ent., vol. 34, p. 292, 1902. 
A small blackish mosquito. Mesonotum silvery gray on the sides; 
a dark brown median band, joining the short posterior lateral bands. 
Abdomen black, with even basal segmental white bands; venter white 
scaled with black bands at the apices of the segments. Legs black, 
the femora whitish beneath; tips of femora and tibiae and tarsal 
joints at basés and apices narrowly white, the last hind tarsal all 
white. Wing scales all blackish. 
The larvae live in holes in rocks along streams and the edges of 
lakes. The winter is passed in the egg state, the eggs fastened on the 
side of the rock. In summer generations the eggs are scattered loosely. 
The adults are good biters in the vicinity of their breeding places, 
which are necessarily very restricted, so that the species is never more 
than locally common. The mating habits of the males are unknown. 
Distribution —Atlantic coast region from Virginia to New Eng- 
land. Specimens from Saxeville, Wisconsin, reported in the mono- 
graph, are not this species but canadensis.
