posterior angles attenuated, prominent and acute : 

 elytra fulvous, with four elevated lines, w^hich 

 are alternately larger, the suture and exterior 

 edge are also elevated; interstitial spaces w^ith 

 numerous transverse elevated lines; near the 

 base, is a broad black band, which nearly reaches 

 the middle, and is continued along the suture to 

 the base; a much dilated terminal black band, 

 which does not reach the middle; both these 

 bands are slightly tinged with violaceous : wings 

 blackish, the nervures margined with whitish: 

 feet sericeous. 



OBSERVATIONS. 



This species may well be said to inhabit North 

 America, for it would seem to be found in almost 

 every part of it, excepting, perhaps, the region 

 beyond the Rocky Mountains, and the more 

 northern inhospitable solitude of Canada. I have 

 received it from Mr. Holmes of Maine, and have 

 myself found specimens in Missouri, North-West 

 Territory, and East Florida. In Pennsylvania 

 it is very common. 



The elytra of the male, are more dilated behind 

 than those of the female.
