Penn., N. J., (Coll. Am. Eat. Soc). Albany, N. Y. (Dr. Peck.) 

 Var. J. — 9. Antennae 22-jointed, the ten basal joints black, the 

 next eleven yellow white, apical joint very small, brown black ; a spot 

 behind each eye, and the basal one-tburth of hinder tibia) and of their 

 first tarsal joint, yellow-white ; a bind across most part of segments one, 

 five and six of tergum, and all the remaining apical segments of abdo- 

 men including cornus, ruby-red ; second, third and fourth sogment;) 

 and terebra black ; wings dark violaceous. — (New Jersey.) 



This fine species is allied to U.albuornis, which it resembles in form, 

 in having part of the antennae, a spot bahind each eye and the basal 

 part of certain tibiae and tarsi, white. It differs in h:iving the ten basal 

 joints of antennne black, the tergum more or less banded with rufous 

 and only the hinder tibiae and tarsi white-bauded. The velvety appear- 

 ance of the tergum is owing to the numerous delicate punctures upon 

 its upper surface.
