Aedes fletcheri Dyar, Ins. Ins. Mens., vii, 27, 1919. 

 A localized form of limited distribution, found on the Cana- 

 dian prairies and the forest adjoining from western Ontario 

 to eastern British Columbia. Mr. Knab found the larvae in 

 early spring-pools, associated with those of spencerii and 

 curriei, although he found that they throve best in the deeper 

 reedy pools of a more permanent character. There is thus a 

 tendency toward the habits of the "long-tubed" type of larva, 

 accompanied by the appropriate modification of structure. 

 The yellow color of the adults is probably an adaptation to the 

 prevailing tone of the open prairie. 



Aedes fletcheri aloponotum Dyar. 



Aedes aloponotum Dyar, Ins. Ins. Mens., v, 98, 1917. 

 Aedes aloponotum Dyar, Ins. Ins. Mens., viii, 27, 1920. 



In the absence of a male, this form can be only tentatively 

 placed. I am inclined provisionally to regard it as a western 

 race of fletcheri inhabiting the moist Pacific Coast strip.
