330 A Monograph of Culicidae. 



Habitat.— -Karner, K York (E. P. Felt). 



Time of hatching, — May. 



Larva. — Very like that of 0. subcantans, Felt, but may be 

 told by the longer tapering air tubes and the smaller number of 

 slender comb scales, and from C. fitchii by its stouter air tube 

 and particularly by the two isolated, well separate teeth 

 terminating the pecten. The comb scales also differ slightly. 



Life-history. — Apparently winters in the egg stage, the ova 

 hatching out in the early spring. One generation only, the 

 species not being met with after the end of May. The larvae 

 are confined mainly to grassy pools, sheltering under overhanging 

 grasses (Felt). 



Observations. — Redescribed from material sent me by Prof. 

 E. P. Felt. It comes very near cantans and subcantans, but the 

 thoracic adornment differs. Grossbeck's C. siphonalis is said to 

 be this species.
