Kruner states that this insect feeds upon sagebrush, though it is 

 uncertain whether this is the sj>ecies he refers to in his statement, since 

 the s[»ecimens received from him bear another name.

In this small group the ])roz<)na of the male is (pnidrate or subquad 

 rate, and the interspace between the mesosternal lobes is as in the 

 spretus series; in front of these lobes, also, the mesosternum of the 

 male lias a central swelling forming a blunt tubercle. The antennae 

 are rather short and ditter but little in the two sexes. The tegmina 

 are fully developed, but rather short, surpassing the hind femora but 

 little if at all, and clear or feebly maculate; the hind tibiae are red, 

 with normally eleven spines in the outer series. 



The supraanal jdate is rudely clypeate and longer than broad; the 

 furcula well develoi)ed, consisting of tlattened, parallel, more or less 

 tapering fingers, half as long as the supraanal i)late; the cerci are 

 laminate and simple, very broad and short, subequal, broadly rounded 

 api<'ally, a little upcnrved; the subgenital plate is peculiar, being 

 exceptionally Icmg and exceptionally broad, exceptionally elevated 

 and prolonged al apex, the apical margin strongly rounde<l and 

 mesially entire, though in one species laterally notched, an exceedingly 

 exceptional feature. 



The species, three in number, \ :y from a little beh)w the medium 

 to rather large sized. They are foi nd mainly in the Cordilleran region 

 from about latitude 38° northward into Canada.
