Aédes prolizus Dyar, Ins. Ins. Mens., vol. 10, p. 1, 1922. 
A rather large blackish mosquito. Mesonotum light yellow, with 
2 broad central single brown band. Abdomen black, the pale bands 
much narrowed dorsally or reduced to lateral spots;,venter yellow- 
ish white, with apical segmental black bands, triangularly widened 
and joined medioventrally into a continuous stripe. Legs black, the 
femora white beneath, tips narrowly white. Wing scales black. 
The markings are somewhat softer and less contrasted than in 
normal punctor; but there is no tangible difference. The male geni- 
talia are, however, diagnostic. 
The life history is unknown; but there is no reason to suppose 
that the habits differ from those of its congeners. The larvae will 
be found to develop from over-wintering eggs in the early spring 
pools. 
Distribution —Central coastal region of Alaska.

white, but sometimes very inconspicuously. Mesonotum creamy yel- 
lowish, a diffused brown stripe in the middle of variable width, and 
a little brown on the lateral margins. Abdomen with grayish white 
basal segmental] bands and a longitudinal mid-dorsal line, cutting the 
black ground into paired quadrate spots; venter pale, with median 
row of black spots. The pale scales on the abdomen vary, sometimes 
covering the whole surface. Legs black, with white scales intermixed, 
femora white below; tarsi with dull white rings at both ends of the 
joints. Wing scales dark and whitish, rather evenly intermixed, 
though the third vein is predominatingly dark.
