Type-locality. — Holliday, Utah.

 ments vary in length. 



Legs : All tibiae, front femora (except occasionally in basal region) 

 and distal one-half to one-fourth of middle and hind femora reddish- 

 brown ; basal portion of femora dusky. 



Antennae: First funicle plus ring-joint about equal in length to
