MOSQUITOS OR CULICIDAE OF NEW YORK STATE 28D 



Distribution. Tliis species is widely distributed in America, 

 having been recorded by Howard from a number of New England 

 and New York localities, from Ottawa, Canada, and in the Sas- 

 katchewan river, British America, Colorado, iirizona. New Mexico 

 and Mexico, while Theobald lists it on the authority of various 

 writers, from England, Germany, Scandinavia, Russia, Italy, 

 India and Australia. 



Life history and habits. This mosquito is very common at 

 Poughkeepsie, and according to Dr Dyar flies most of the 

 summer, though there is but one generation. The larvae appear 

 to survive the winter in this latitude, though Dr Dyar states 

 that they hatch from overwintering eggs very early in the 

 spring, and that the growth is not rapid, a month probably 

 being required for the production of adults. Our belief is 

 based on the fact that full grown larvae are first observed 

 in the spring and as their appearance is nearly coincident 

 with that of other aquatic forms, we doubt the possibility 

 of their developing from eggs in this latitude. Dr Dyar states 

 that this species flies some weeks before depositing eggs and 

 becomes common in the woods of British Columbia in July, dis- 

 appearing soon after. A female taken by him, in New Hamp- 

 shire, was kept alive from July 20 to Aug. 12, audi another cap- 

 tured Aug. 8 laid eggs the 16th. A female taken June 15 in 

 British Columbia oviposited the 30th, the eggs remaining 

 unhatched till the following year, the wrigglers appearing as soon 

 as the ice had melted from the jar the next spring. The eggs are 

 laid singly and readily sink in the water. Dr Smith states that 

 the larvae of this mosquito occur in woodland pools and springs 

 in early spring with those of C. canadensis.

This exceedingly common species about Albany has been taken 

 in widely separated New York localities. It greatly resembles 

 C. cantans according to Johannsen, and also agrees fairly
