to mature till the first of December. This species has also been 

 taken at Ithaca. 



Dr Dyar has met with this species in New Hampshire, where 

 the larvae occurred in all sorts of temporars' pools, swamps, 

 meadows, roadside puddles and the like. Thev were associated 

 with C. canadensis and A e d e s f u s c u s . and he states 

 that the three species have essentially similar habits. He records 

 collecting all the larvae from a roadside puddle, and on visiting 

 it after the next rain found it filled with the same three species, 

 and he therefore inclines to the belief that the eggs were lying in 

 that place and that some hatched after each rain. Dr Smith 

 states that this species occurs throughout New Jersey, and that 

 it is the most common of the fresh-water swamp mosquitos after 

 midsummer and till well along into -fall. It bites readily, often 

 occurs in considerable swarms, flies quite a distance and fre- 

 quently enters houses. He adds that this species prefers rather 

 open swamps and is as common in New Jersey in the marshy 

 stretches near the Delaware, as in the low ai'eas of the Great 

 Piece meadow region. He states that it is rarely found in dark 

 woodland swamps or in cat-tail areas, but that it occurs in more 

 open water. It breeds in larger, more permanent meadow or lot 

 pools and rarely in clean gutters. It is not a foul water mos- 

 quito and does not ordinarily occur in tubs, pails or rain barrels, 

 nor has he ever found it in rain water or in open ponds. 



Dr Smith states that the winter is passed in the egg stage and 

 usually at the bottom of a pool, though the eggs may be laid at 

 the edge of a puddle or in a damp depression likely to become 

 filled with water. Dr Dyar states that eggs obtained by him 

 from captive females were essentially like those ofC. canaden- 

 sis and C. cantans, laid singly, sinking in the water. They 

 were obtained by him late in the season and did not hatch. Dr 

 Smith records several broods during the season and states that 

 the number depends on the amount of rain that falls and form» 

 or maintains the normal breeding areas. The species breeds in 

 both permanent bodies of water and temporary pools, provided 

 the latter are suitable. The time of development is about 10 days.
