I have based this species upon the male specimens just quoted, but I 

 have also three females from Lakin and Pueblo, with short wings and 

 long hind femora, which I think belong here, but which resemble 

 A. elliotti more than do the males. The species is smaller than any ol 

 its congeners, with shorter wings, longer hind femora, and Bubtruncate 

 posterior margin of the pronotum.
