One of our prettiest species of Bemhldlum. It is the smallest and 

 most slender species of the group, easily recognizable from the others 

 and apparently subject to but slight variation. 



The males are much more abundant than the females, of the sev- 

 enteen specimens examined but three being of the latter sex. 



I take great pleasure in dedicating it to Mr. Samuel Henshaw of 

 Cambridge, to whom I am much indebted for assistance in many 

 ways. 



It is known to me from Sherman, Wyo. (Garman), Salt Lake,
