Genus Uranotaenia Lynch Arribalzaga. 



A small genus, mainly of tropical distribution. The larvae live in 

 ground pools, and have a superficial resemblance to Anopheles, from the 

 elongated black head, and the habit of lying flat in the water, although 

 the larvae are not surface-feeders. The adults are ornamented with lines 

 of metallic blue scales. 



Uranotaenia sapphirinus Osten Sacken. 



Aedes sapphirinus Qsten Sacken, Trans. Am. Ent. Soc, ii, 47, 1868. 



A small blackish mosquito. Mesonotum brown, thinly scaled, a 

 narrow line of metallic blue scales to the scutellum ; a lateral line on each 

 side, running to the wing. Abdomen black above; venter grayish. Legs 

 black, femora pale beneath; tips of femora and tibiae with a pearly white 

 spot. Wing-scales all dark. 



The winter is probably passed in the adult state. Eggs are laid in 

 boat-shaped masses floating on the water. The females are not trouble- 

 some. I have no certain records of the biting. The habits of the males 

 are unknown. A rare species, seldom seen unless bred. 



Distribution: Eastern United States from, the Gulf of Mexico to 

 northern New England, possibly in southern Canada.
