 Amula 6000 feet, and Mescala, all in Guerrero (H. H. Smith).

 anterior tarsi in the male have a scarcely perceptible fringe of very short hairs beneath. 



Diplotaxis trapezrfera (p. 159). 



Var. 1. D. consentanea. 



To the Mexican localities given, add : — Omilteme in Guerrero 8000 feet (H. H. Smith).

clypeo breviter trapezoideo lateribus subrectis. 

 Long. 7-9 millim. 



Eab. Mexico, Temax in North Yucatan (Gaumer). 



Many examples, offering very little variation. The clypeus is perceptibly a little 

 shorter than in the typical D. trapezifera ; form, sculpture, and dentition of claws offer 

 no difference.
