Nained Peniatoma serieventris by Mr. Say, but never published. 

 The inner basal angle of the membrane is very dark brown, and the 

 apical streak quite broad at tip. A specimen from Massachusetts in 

 my own collection is quite orange-rufous above. The lateral margins 

 of the anterior lobe of the pronotum are quite distinctly denticulato- 

 serrate; and pale yellow. The species is known to me from Minne- 

 sota, Maine and Massachusetts.
