I obtained this species on the Expedition of Major Long to 
the Sources of the St. Peters river. It is much like constrictus 
Nob., but the thoracic stricture is a little nearer to the posterior 
margin and the arrangement of colors on the hemelytra is 
different.

transverse line before; hemelytra whitish with a fuscous spot.

reflection; basal edge piceous; scutel with a carinate line: 
hemelytra yellowish-white and punctured on the corium, the
