The phallus in the form of a rectangle with a parallel tube with an intensely sclerotized transverse distal margin. Fourth instar larva (Fig. 83, b and c). The antennae are usually as long as the head. The antenna! tuft is relatively weakly branched (15-20 setal branches). The median frontal setal index is about 150%. The siphon seta has 3-7 branches. The ventral brash bears 11—12 setae set on the common base and 5-7 setae anterior to the common base. Distribution (Fig. 82). USA (Minnesota, Wisconsin, Massachusetts, New York, New Jersey, Delaware, Utah, Idaho and Montana). Biology. These are mosquitoes of the forest-free regions of the hills. Not reported from human habitations; the host not Fig. 82.
