Culex varipalpus CoquiLtett, Can. Ent., vol. 34, p. 292, 1902. 
Taeniorhynchus sierrensis LupLtow, Can. Ent., vol. 87, p. 231, 1905. 
A small blackish mosquito with white-ringed legs. Mesonotum 
dark brown, ornamented with a patch of light golden scales in front 
and a narrow line of the same from the lateral groove backward. 
Abdomen black, with basal segmental even white bands; venter 
whitish scaled. Legs black, the femora white below; tips of femora 
and tibiae and the apices of the tarsal joints silvery white, involving 
the bases of the joints to a less extent; rings narrow, except on the 
hind legs, where they are broad, involving the whole of the last joint. 
Wing scales wholly dark, thick and dense. 
The larvae live in the water in holes in tree trunks, occasionally in 
artificial receptacles. The winter is passed in the egg state; it is not 
known whether there is more than one annual generation. The fe- 
males occasionally occur in annoying numbers in old forests, but are 
usually rare. The males form little swarms in the daytime about 
some stationary warm-blooded animal, and mate with the females as 
these come to bite. 
Distribution —Pacific coast region from southern California to 
British Columbia.
