 Culex pallidocephala Theobald, Mon. Culic, v, 612, 1910. 



A rather small blackish mosquito. Mesonotum dark brown. Ad- 

 domen black, with a continuous lateral white line, but also with this line 

 broken into spots and with more or less distinct basal segmental white 

 bands; venter whitish scaled. Legs black, the femora whitish beneath. 

 Wing-scales all dark. The male has short palpi as in the female and is 

 easily recognized thereby. 



The winter is passed in the egg state, the larvae developing in early 

 spring pools, but also, following rains, during the summer. The later 

 emergencies are less numerous. The females are good biters in woods 

 and thickets, not coming into the open. The males swarm after sunset 

 in openings between willows and similar locations. 



Distribution: Northern North America and northern Europe.
