A SYNOPTIC TABLE OF NORTH AMERICAN 

 MOSQUITO LARVAE. 



By Harrison G. Dvar, A.M., Ph.D., 

 Washington, D. C. 



I have had this table in hand for over a year, but have been dis- 

 suaded from printing it by Dr. Howard, who advised delay on the 

 ground that new forms were continually being found. Now, however, 

 we have at hand all the larvae of the known species of the Atlantic- 

 Coast region with the exception only of a few rare or doubtful forms, 

 namely Culex niveifarsis Coq. and C. onondagensis Felt, recently de- 

 scribed, Anopheles nigripes Staeg., A. bifurcatus Linn, and Culex 

 squamiger Coq., of doubtful or recently recorded occurrence and 

 Culex hirsuteron Theob. and C. testaceus YVulp., of doubtful identity. 



There are a number of Western species still unknown in the larva, 

 while the West Indies and Mexico as well as the Arctic regions are 

 largely unexplored. Still, as the table seems likely to be useful in its 

 present form for the Eastern United States, it is herewith presented.
