Genus Etorleptiomyia. 505 



base ; lateral tuft just below the middle of the antennae ; apex with 

 two spines, one longer than the other and two bristles ; labial 

 plate with 12 to 15 (12 to 14, Smith) teeth on each side of apex. 

 Scales on eighth abdominal segment 28 to 34, no definite arrange- 

 ment ; each scale has a large apical spine, and the others decrease 

 from it basally. Anal siphon four times as long as wide ; with two 

 series of toothed spines, each ranging from 17 to 22, these are jet 

 black with paler tips (J. B. Smith says white, probably in live 

 specimens), each spine having four teeth on one side, some in 

 two distinct pairs, but not all • anal gills nearly as long as ninth 

 segment, bluntly acuminate. 



Habits of larvae. — Mr. Grossbeck found these larvae with 

 those of Culex canadensis in April at Paterson, New Jersey. In 

 May they are again recorded by Prof. J. B. Smith as occurring 

 with canadensis, a male squamiger emerging on May 8th. Nothing 

 is known further of their habits at the time of going to press. 



It comes in a very distinct genus. Xo Culicid has been seen 

 like it from any part of the world. 



As there is only one $ no attempt has been made to describe 

 the genitalia and ungues. 



Coquillett gives Miss Ludlow's niedmannii as a synonym of 

 this species, and I understand from Miss Ludlow that she agrees 

 in this respect.
