ing in having a longer breathing tube which tapers regularly from 

 base to tip and is free from local swelling or inflation. 



Importance 



At the present time we have no reliable evidence to show that this 

 species is of any great economic importance. It shows the same 

 house-infesting tendency as C. pipiens and may, when the houses 

 come within its range, prove very troublesome. Some years ago 

 this species and C. pipiens bred in enormous numbers on certain of 

 the sewage-charged salt marshes, and mosquitoes collected in the 

 vicinity showed considerable numbers of the lanky dark form. It 

 may eventually be proven that under these conditions C. salinarius 

 plays almost as serious a role as C. pipiens.

Life Habits 



This mosquito, like C. pipiens, winters in the adult stage in pro- 

 tected places. Hibernating specimens have been found in buildings 

 along the edges of the marsh. In April they desert their winter 

 quarters, begin breeding and may continue until October. The 

 eggs are laid on the surface of the water in a mass like those 

 of the house mosquito (C. pipiens Linn.). The egg boats of this 

 species are loosely formed and break up quickly. While the larvae 

 appear everywhere on the marsh, they occur in decidedly greater 

 numbers near the upland. 



C. salinarius is most abundant on the Elizabeth, Newark and 

 Hackensack marshes. During 191 3 it bred most abundantly in the 

 sewage-charged marshes in the same water with C. pipiens.
