Bred from isolated larva taken from permanent pool at Karner 



May 12, adult appearing May 16. 



Larva. About 14 of an inch long. Head probably pale brown ; 

 antennae slender, slightly curved, dark at tips; tuft just before 

 the middle, and the curved surface thickly cl'othed with fine scales, 

 giving the edge a peculiar serrate appearance. Labial plate 

 broadly rounded, with 23 teeth. Comb is composed of about 25 

 triangular, stoutly spined scales arranged in two or more rows; 

 some of the scales have a very stout, terminal spine with smaller 

 ones along each side, while 'others have the tips somewhat rounded 

 and the spines more nearly of a size. Air tube fully five times as 

 long a® its greatest diameter, tapering somewhat regularly and 

 with a slight bend and contraction near the middle. Basal rows of 

 pecten, each consisting of about 22 closel}^ set teeth bearing at 

 their basies usually two largeir and three or four finer sierrations. 

 There is a compound bunch of hairs slightly beyond the row of 

 pecten, all on the basal half of the tube. Ventral tuft rather 

 thick, confined to the barred area; dorsal tuft composed of one 

 rather large, compound hair and two very long, slender hairs, the 

 latter being about half the length of the body. 



Described from cast skins of isolated larvae from which adults 

 were bred. 



This larva was associated with C. canadensis, C. c a n - 



tans, C. cinereoborealis, C. impiger and Aedes 



f u s c u s in a rather permanent woodland pool. It proved quite 



difficult to rear.

This common mosquito (C. s t i m u 1 a n s of Coquil left's table) 

 may be distinguished from others having basal bands on the tarsi, 

 by their being wider as compared with those of 

 C. sylvestris [fig. 24] , and from the other 

 three native species because all the claws bear a 

 tooth. Theobald and Johannsen were both mis- 

 taken in supposing that the posterior claws were 

 simple [fig. 23], and the former has corrected

cantans fj^^ World. 



This species was taken at De^mar in a woodland pool, Ap. 25, 

 1903, and a number of adults bred therefrom up to June 19, and at
