being strongly rcflexod in trapizoidal process, which is emargi- 

 natc aliove. Prolhoracic process abrupt and deeply emarginate 

 al middle. A circular fovea at posterior border of first ventral 

 segment. The other segments transversely strigose. Length 

 2-04 nun. I took this species at Grand Lake, Middle Park, 

 Colo. Only males were seen. 



A subspecies of the above was taken in Grant Co., New 

 Mexico. It is about the same size and proportions, but differs 

 in having an impressed space behind the prothoracic process, 

 and having this j^rocess more gradually formed. The pro- 

 thorax is always red and the posterior part of elytra is always 

 with traces of this red color. Ten specimens. Both sexes.

An examination with high power shows that each joint 

 of the antennal club has a large fovea and a small denticle on 

 the outside of joint. The third joint is as long as the first and 

 second.
