suture near the tip; edge all round, black: be- 

 neath rufous. 



OBSERVATIONS. 



The similarity of this species with the pre- 

 ceding, is obvious, and even striking; but it is 

 specifically distinguished by the existence of 

 two black lines on the elytra, in place of the 

 exterior one of that insect. I obtained several 

 specimens near the Rocky Mountains, when 

 with Major Long's party in that region, but it 

 does not appear to be an inhabitant of the At- 

 lantic States.
