Aedes, but E. P. Felt, J. B. Smith, and others have placed it in 

 the genus Wyeomyia. 



Since then I formed the genus Dendromyia, in which the wing 

 scales are broader than in Wyeomyia. It comes in the former genus. 



This is the insect referred to under Aedes fuscus (Yol. III., 

 p. 286) as living in its larval stage in the pitchers of Sarracenia 

 — a note taken from Howard's " Mosquitoes," p. 153 (1901), 

 in which Uranotaenia sapphirina is figured as Aedes fuscus on the 

 same page. 



The habits and life-history are ably given by Professor J. B. 

 Smith. From this author the following is abridged : —

The adult is disinclined to bite. The resting position is similar 

 to that of all Wyeomyias, the hind legs being held up above the 

 body over the back. 



The adults appear towards the end of May and issue irregularly 

 until early November. The larvae live in the water that is found 

 in the pitchers of the Pitcher Plants (Sarracenia), often in large 

 numbers. The water in these pitchers freezes in winter, and the 

 larvae are found completely frozen. This does not in the least 

 affect them. Mr. Brakeley cut out a few of the pitcher plant 

 leaves, stripped them from the core of solid ice, and found the
