Black ; antennae and large wing spot, yellow. 



DESCRIPTION. 



Body black, tinged with purplish : antennse, 

 excepting the first and second joints, bright 

 yellow: wings violaceous-black; superior pair

OBSERVATIONS. 



On a recent journey, in company with Mr. 

 Maclure, I had the gratification to find this 

 handsome species in the vicinity of Easton, 

 Pennsylvania. I have not seen it elsewhere. 

 Only a single specimen occurred, which is a 

 female.
