URANOTAENIA SAPPHIRINUS Osten Sacken. 
Aédes sapphirinus OSTEN SACKEN, Trans. Amer. Ent. Soc., voi. 2, p. 47, 1868. 
A small blackish mosquito. Mesonctum 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. Wang scales dark, a line of blue ones on 
basal half of fifth vein. 
The winter is probably passed in the adult state. Eggs are laid 
in boat-shaped masses floating on the water. The females are not 
troublesome. I have no certain records of the biting. The habits 
of the males are unknown. A rare species, seldom seen unless bred. 
Distribution.—Kastern United States from the Gulf of Mexico to 
northern New England.
