about two-thirds the length of the cell ; posterior cross-vein 

 longer than the mid, not quite it own length distant from it. 



Halteres pale with pale creamy scales. 



Length. — 5*5 to 6 mm. 



Habitat. — New Jersey, U.S.A. (J. B. Smith) ; New Hampshire 

 (D. W. Coquillett); Elizabethtown, N.Y. (E. P. Felt) ; Connecticut 

 (H. L. Yiereck). 



Observations. — I have redescribed this from specimens sent 

 me by Professor J. B. Smith from Lahaway, N. Jersey. It is quite 

 distinct and comes in Felt's genus Culicada. Coquillett described 

 it from New Hampshire. It is a most bloodthirsty species. It 

 never occurs far from its breeding places, and does not enter 

 habitations. It flies some distance by night, and will attack man 

 during the day if he enters its haunts. The earliest date of 

 appearance is given by Smith as April 23rd, the latest for larvae 

 May 10th, and the adults came out on May 13th. They occurred 

 as adults as late as July 24th. 



The larvae have been carefully observed by Brakeley and 

 recorded by Smith. They are usually associated with Culex 

 canadensis. He found the first larvae March 23rd in large bodies 

 of water covering the bogs, and in reservoirs and pools. They 

 favour tufts of grass, rushes or vines several feet from shore. 

 The pupa has white air tubes. The eggs are probably ]aid in 

 the mud. 



They were present in a cranberry bog which was dry during 

 the summer of 1902, and till so late in the fall that all mosquito 

 life had gone into hibernation or disappeared. The larvae being 

 found so early led Professor Smith to assume that they hibernate 

 as eggs.
