One of the most ahundaiit of tlie Pentatoniids occurring in the 

 eastern United States and Canada. Its western limits seem to be 

 Texas, Colorado and Washington, hut it is much more at home east 

 of the Rocky Mountains as far south as Mississippi. It was rede- 

 scribed as Pentatoma bhnacidata by Thomas, in Trans. 111. State 

 Ag. Soc, V, p. 455, 1865.

 I have not yet seen this species. It is described as " castaneous," 

 so it should be easily recognized from our other species. The types 

 came from Nevada and California.

I have specimens of this species from Colorado and Montana 

 (Cooley), and California (Heidemann). Its range extends from 

 Vancouver Island to jNIexico and Lower California. It seems to 

 replace carnifex west of the Rocky Mountains.
