(Plate I.) 



This mosquito flies most of the summer, but it is single brooded. 

 The larvae hatch from over-wintering eggs very early in spring, but 

 the growth is not very rapid, probably a month being required before 

 adults appear. These fly some weeks before becoming ready to 

 oviposit. A female at New Hampshire was kept alive from July 20 to 

 August 12 ; another taken August 8, laid eggs August 16. In British 

 Columbia, a female taken June 15, laid eggs June 30 and these 

 remained unhatched till the following year, although kept in water. 

 They hatched as soon as the ice was melted in the jar the following 

 spring. 



The eggs (Plate I, Fig. i ) are laid singly and readily sink in the 

 water. They are elliptical, the thickest part at one third from the
