Length, 7 millimeters. 



One specimen from Colorado, collected by B. H, Smith. The original 

 type came from the region of the Saskatchewan in British America. 



The description is added in this place to call the attention of western 

 collectors to this interesting and peculiar species, with a view to obtain- 

 ing a series of both sexes for the better elucidation of its affinities, and 

 to establish its position in the group. 



In Europe, this genus is represented by two species — one in France 

 and Hungary, and the other in Sweden and Kussia; but this is the first 

 time that we have had evidence of the presence of one of its represent- 

 atives on this western continent. 



SuPERFAMiLY PENTATOMOIDEA. 



Scutellum much narrower than the abdomen, contracted behind the 

 middle, usually triangular, having a fra'uum running from the base
