Aedes riparius Dyar & Knab. 



A'cdes riparius Dyar & Knab, Journ. N. Y. Ent. Soc, xv. 21o, 

 1907. 



Described from Winnipeg, Manitoba. In the monograph we 

 add the localities Aweme, Manitoba, and Saxeville, Wisconsin, 

 from females and therefore not certainly placed. A. fletcheri 

 Coq. is not distinguishable in the female. Demonstrated males 

 are before me only from Winnipeg, the type locality. The 

 larva is unknown. 



Aedes fletcheri Coquillett. 



Culex fletcheri Coquillett, Proc. U. S. Nat Mus., xxv, 84, 1902.i 



This species has been considered peculiar to the prairies ; but 

 it occurs in the forest as well, as I demonstrated a male from 

 Red Deer, Alberta, taken in spruce forest, August 3, 1918. 



Unassorted specimens of riparius and fletcheri were taken in 

 127 examples, as follows : White River, Ontario, June 24, 

 1918; Nipigon, Ontario, June 26, 1918; Dryden, Ontario, June 

 30, 1918; Kenora, Ontario, July 2, 1918; Winnipeg Beach, 

 Manitoba, July 4-5, 1918 ; Saskatoon, Saskatchewan, August 

 11-13. 1918; Prince Albert, Saskatchewan, August 14-17, 

 1918; Red Deer, Alberta, July 29-August 3, 1918; Lochearn, 

 Alberta, August 5-7, 1918; Lamoral, Alberta, August C^, 1918. 



iThe synonyms given in the monograph, flavescens Theobald (not 

 Fabricius) and arcanus Blanchard, do not belong here, the form in 

 question being from Finland as shown by F. W. Edwards (Entomolo- 

 gist, 1912, p. 218). It is said to he either maculatus Meigen, or a spe- 

 cies near to that.
