black abdomen. The antennae are only slightly reddish beneath to-

 scopically transversely lineolate; mesothorax and scutellum dullish 

 rather dark blue-green ; pleura dark blue-green ; tegulae piceous ; wings

Longs Peak Inn, Colorado, July 19 (Cockerell). Also one 

 on July 21. A western mountain representative of H. viri- 

 datus. The sculpture of the metathoracic area separates it at 

 once from the superficially similar H. ruidosensis Ckll. In 

 the second specimen the upper part of clypeus and supra- 

 clypeal area are not brassy.

 the type by the blacker abdominal bands, larger yellow mark on sides 

 of second segment, and pair of subdorsal yellow spots on fourth and 

 fifth segments.
