large^ apical spine. Air tube about three times as long as wide, 

 tapering regularly, with double posterior pecten on basal third, 

 each row consisting of from 12 to 15 closely set (except the slightly 

 separate terminal three) stout, black spines, each bearing near 

 the basal third one large and usually a smaller tooth. Barred 

 area short, dense, bearing numerous long, branching hairs. Anal 

 gills long, slender, uniformly tapering. 



Culex nemorosus Meig. 



This large species may be separated from others in the group, 

 by the very long petiole of the first submarginal cell, which is 

 longer than the cell itself. It has been recorded by Theobald, 

 from Lapland to Italy and has been received by him from a 

 number of Canadian localities. It should occur in New York 

 State, though we have not met with it.

 Unhanded salt marsh mosquito

This species was known under the name of C. nigritulus 

 Zett. in this country till Mr Coquillett showed that it could not be 

 identical with the European form and proposed the above name 

 therefor. It is closely related to C. pipiens, but may be dis- 

 tinguished from it by the indistinct abdominal cross bands which 

 are widest at the middle. It is also a smaller species. 



This larva may be easily recognized, according to Dr Smith 

 by its dirty white color and the very long, moderately stout air 

 tube. The labial plate is broadly triangular with eight teeth 

 on each side. It has double pecten, each tooth coarsely three 

 spined. and scattered hairs beyond. The comb consists of a 

 patch of about 10 narrow long fringed scales in three rows. 



Distribution. This salt marsh form has been recorded by Dr 

 Smith in association with C. sollicitans. We have taken 

 it in small numbers in Xew York State. 



Life history and habits. Dr Smith states that, though the larva 

 may occur anywhere on the marsh, in brackish as well as fresh
