A medium-sized to smal] brown mosquito. Mesonotum, a little 
paler about antescutellar space. Abdomen black, with narrow white 
basal segmental bands, tending to be notched on dorsal line; lateral 
spots separated therefrom, quadrate and elongate; venter whitish 
scaled, with more or less distinct median blackish spots. Legs black, 
femora pale below; tarsi with very narrow white rings at the bases 
of the joints. Wing scales wholly dark. 
The winter is passed in the egg state, the larvae hatching in early 
ground pools, but also later in the season whenever the pools are filled 
by rain or otherwise. However, there may not be more than one an- 
nual generation. The females are severe biters in woods and thickets, 
not frequenting the open. The males swarm after sunset, sometimes 
in very large groups. This is the commonest woods mosquito 
throughout the country, but it does not extend to high altitudes or the 
forests of the Canadian zone. 
Distribution —North America, from the Mexican Plateau to Can- 
ada, except on the Pacific coast and far north; Europe, northern 
Asia.
