Aedes quadrivittatus Coquillett. 



Ciilex quadrivittatus Coquillett, Can. ent., xxxiv, 293, I 902. 



An examination of the types of this species shows it to be refer- 

 able to Aedes, the tarsal claws of the fernale simple. Mr. Coquillett 

 described it originally in comparison with Aedes afropalpiis Coq., 

 with which it has no affinity, thus producing a misleading impression. 



Aedes fletcheri Coquillett. 



Ciildx flavt'scens Theobald (not Fabricius, not de Villers), Men. Culic, i. 410, 

 I901. 



Ciilex fletcheri Co(\m\\c\.\., Proc. U. S. Nat. Mus., xxv, 84, 1902. 

 Cu/ex arcaiius Blanchard, Les Moust., 303, 1904. 



Theobald's description of Ciilex flavescens from old specimens in 

 the Hopeian Museum at Oxford appears to agree with our y?^/r//if;7 from 

 the Canadian prairies. We think it may be safely identified with this 

 species.
