Culex siphonaUs Smith, N. J. Agr. exp. Sta., Rept. Mosq., 245, 1905. 



One of the early Spring forms with northern distribution. The 

 senior author collected specimens in Kaslo, B.C., which were named 

 first "Culex cantans Meig." and a description published under that 

 name (Journ. N.Y.ent. soc, xii, 36, 1904). Later the determination 

 was changed to il GrabhamiaviUata Theob.," but it cannot possibly 

 be that species to judge from Theobald's figure (Can. ent., xxxv, 

 313, 1903)- The figure is too sketchy to admit of placing the 

 form in a table, though we conjecture it to be intended for some 

 species of Culiseta.

Aedes impiger Walker.

 Culex nigripes Blanchard (in part), Les Moustiques, 345, 1905. 



One of the earlv Spring species which was discovered by Dr. E- P. 

 Felt in northern New York. We are not at all sure that Walker's 

 species is determinable, but having been, thus fixed by Dr. Felt, it 

 will be better to accept it. The species referred to by the senior 

 author as impiger (Proc. ent. soc Wash., vi, 37, 1904) is pullatus 

 Coq., and the forms referred to by us (Proc. ent. soc. Wash., vi, 144, 

 1904,) are a mixture of pullatus Coq. and trichurus Dyar. Theobald 

 and Blanchard refer our species to the synonymy of nigripes Zett. of 

 Europe ; but we have as yet no evidence that any of these American 

 species occur in Europe.
