 with a few whitish scales. Occiput rather thickly clothed with 

 yellowish and silvery scales, with a few black ones interspersed.

 scales, becoming grayish posteriorly (in the specimen this portion

This mosquito resembles C. canadensis, though it may be 

 separated from it by the length of the petiole of the first submar- 

 ginal cell, as given above. This species has been recorded from 

 several localities near New York State, and Prof. G. H. Hudson 

 has taken it near Plattsburg N. Y.
