DISEASE-BEARING AMERICAN MOSQUITOES 49 



Culex salinarius, Coq., is very similar to C. pipiens, except 

 that it is somewhat darker and thinner. The larva is distin- 

 guishable from that of C. pipiens by the fact that it has a longer 

 breathing siphon, which tapers uniformly from base to tip. 

 This species, like C. pipiens, winters as an adult, eggs being laid 

 by gravid females in the spring; the eggs are laid in rafts, similar 

 to those of C. pipiens. This species occurs over the whole 

 Eastern part of the United States, breeding in permanent water 

 in the same way as pipiens, fatigans (quinquefasciatus) and 

 restuans. It is, perhaps, most common in fresh-water swamps 

 along the sea-coast but does not occur there exclusively.
