Dyar and Knob Some American Mosquitoes. 



G. oswaldi and G. fluviatilis we can not determine any positive statement 

 in Dr. Lutz's writings on this point. Moreover, the description of oswaldi 

 reads so much like our Aedes insolita Coquillett that we are in some doubt 

 if it is not actually that species. In this case it would be removed from 

 , as insolita has toothed claws in the female.

Haemagogus splendens Williston. 



We restore Williston's name for the species identified as the cyaneus of 

 Fabricius by Mr. Theobald, as we think we have found a species that fits 

 better to Fabricius' description than splendens does, namely Sabethoides 

 confusus Theobald.
