The Mosquitoes of Canada 8i 



A large dark mosquito with spotted wings. Mesonotum uniform, 

 without impressed Unes; vestiture dark, mixed with yellowish white 

 scales, which form diffuse longitudinal lines, and a spot on each side. 

 Abdomen black, with basal segmental white bands; venter whitish 

 scaled. Legs black, the femora v/hitish below, the tibiae also more or 

 less whitish within; tarsi with white specks at the bases of the joints, a 

 rather distinct ring at the base of the second hind tarsal. Wings broad, 

 the cross-veins in line, or nealy so; wing-scales black, hair-like, forming 

 more or less conspicuous spots on the bases of the forks of the second 

 and fourth veins, and along the second and fourth veins within the cross- 

 veins. 



The male genitalia have the unci simple; a short row of spines on the 

 penultimate segment. 



The larvae live in permanent pools of a dirty character, and take 

 readily to artificial receptacles, this being the common water-barrel 

 mosquito of the west. The adults hibernate ; the eggs are laid in narrow 

 rafts on the surface of water. The adults will attack man, but rarely, 

 preferring larger mammals. A man on horseback is generally immune, 

 though the horse may be bitten. 



Distribution : Northern Rocky Mountains and the Pacific coast from 

 southern California to Alaska.
