694 MOSQUITOES OF NORTH AMERICA 



The characters of the adult are variable and do not distinguish Aedes vittata 

 from its allies, stimulans, fitchii, ahfitchii and sansoni, and we know neither male 

 genitalia nor larvae. We therefore hold the species tentatively on the locality 

 solely. We have three specimens from the original lot from which Theobald 

 obtained his type-material. One of them has the last joint of the hind tarsi all 

 black, while another has it distinctly white marked; the third specimen is 

 broken. The larvae credited to this species by Theobald in connection with the 

 original description do not belong to it and are obviously those of Culiseta inci- 

 dens.
