Aedes (Heteronycha) leuconotips Dyar. 



Aedes leuconotips Dyar, Ins. Ins. Mens., vni, 24, 1920. 



A rather large blackish mosquito. Mesonotum brownish yellow, with 

 two median dark brown lines, and short posterior lateral ones of the same 

 colour. Abdomen black, with basal segmental white bands, narrow and 

 narrowed centrally; venter white-scaled, with some black ones at the 

 tips of the segments. Legs black, the femora white below; knee-spots 

 narrowly white. Wing-scales all dark. 



The markings are not distinguishable from lazarensis, although, as 

 seen from the male genitalia and larvae, the species is extremely close to 

 piinctor. The winter is passed in the egg state, the larvae developing 

 in early muskeg-pools in the rainy Pacific coast strip. The mating habits 

 of the males have not been observed. 



Distribution: Pacific coast, British Columbia to Alaska.

 Prince Rupert, British Columbia, May 22, 19 19 (H. G. Dyar). 



Aedes (Heteronycha) cyclocerculus Dyar. 



Aedes cyclocerculus Dyar, Ins. Ins. Mens., viii, 23, 1920. 



A medium sized blackish mosquito. Mesonotum brownish yellow, 

 with two median brown lines, and short thick posterior lateral ones, 

 heavier and blacker than the median ones. Abdomen black, with narrow 

 basal segmental white bands, narrowed centrally; venter whitish-scaled. 

 Legs black, mixed with gray scales, especially below, the femora white 

 below. Wing-scales wholly dark. 



By the male genitalia and larvae, this species is closely allied to 

 punctor. It is a rather small species, the winter being passed in the egg 

 state, the larvae developing in early muskeg-pools in the rainy Pacific 

 coast strip. The mating habits of the males have not been observed. 



Distribution: Pacific coast, British Columbia to Alaska.
