Face with a median broad yellow stripe extending to the antenna? ; 
clypeus and mandibles, except tips, yellow, ^fesonotum with lateral 
cuneiform lines, teg-ulte, spot at base of hind wing, continued as a

Described from a female collected by Prof. T. D. A. Cockerell, 
di Beiilah, New Mexico, during July. 
This species is related to pleuralis Cress, and to rohustus Davis. 
It is separable from the former, by its black plurse and metathorax 
and fewer yellow markings, and from the latter by its much 
smoother body sculpture, and the absence of any central ridge on 
the abdomen.
