Culex eumimetes Dyar and Kwnags, Proc. U. 8S. Nat. Mus., vol. 35, p. 61, 1908. 
A medium-sized or rather large brown mosquito, the mesonotum 
dark brown with more or less of ornamentation of posterior silvery 
lines. Abdomen blackish, with basal segmental white bands, widened 
in the middle; venter pale, with a round black spot posteriorly on 
each segment, more or less developed. Legs black, the femora pale 
beneath, the tarsi ringed with white on both ends of the joints, nar- 
rowly so on the front and mid legs, broadly so on the hind. No 
white line on the outside of femora or tibiae, though these parts may 
be whitish beneath. Wing scales narrow, black. 
The male genitalia are not different enough from those of tarsalis 
to be diagnostic. 
The larvae inhabit pools left in the beds of streams when these 
have gone dry after the seasonal rains in the arid country. They 
may occur also in pools of artificial formation in the same region, 
even fountains or water troughs for horses. 
Distribution.—The arid west coastal region from Central America 
and Mexico to Oregon.
