NEW MOSQUITOES FROM ALASKA 



(Diptera, Cidicidce) 



By HARRISON G. DYAR 



In June and July, 1921, Dr. J. M. Aldrich of the U. S. 

 National Museum made a trip to Alaska, with the happy result 

 of securing males of two forms of Aedes, which had been in 

 the collection many years awaiting names. At the same time, 

 Dr. S. Had wen of the U. S. Biological Survey was in another 

 part of Alaska and obtained breedings from larvae of one of 

 these species. We have, therefore, a better idea of the fauna 

 of Alaska north of the coastal islands than was before available. 



Aedes punctodes, new species. 



Aedes (Ochlerotatus) sp. Dyar, Rept. Can. Arctic Exp., iii, 

 Part C, 33, 1919. 



A species of the punctor group, as shown by the male 

 hypopygium, but differs in having the claspette-filament long, 

 much as in dysanor Dyar, but the basal lobe of side-piece is 

 normal. 



It is a black-legged species, the mesonotum dark brown, with 

 two blackish lines, generally narrow and separated, sometimes 

 broad and contiguous. These marks are but little darker than 

 the ground, sometimes obsolescent, and indistinguishable in 

 flown specimens, the mesonotum of which appears uniformly 

 dark brown like piinctor-abscrratus or intrudens. The abdo- 

 men has broad basal segmental whitish bands, narrowed in the 

 middle, somewhat diffused, especially posteriorly; venter pale 

 gray. Wing-scales all dark, but those on costa, first and third 

 veins are blacker than the others.
