According to Mr. Binney, the western range of this species is Kansas, 

 extending from New England ; but Professor Hayden found it during his 

 Yellowstone expedition. It was found, also, to be very abundant in the 

 locality below indicated, and was not seen elsewhere. Occurs in some of 

 the mountain passes westward.
