The foregoing list of localities shows that suhnuda is a boreal and 

 alpine form like aserra, but unlike this subspecies confined very largely 

 to the Rocky Mountains within the confines of the L'nited States. 

 As I have found no transitions between it and the t;^7)ical ruhicunda, 

 I believe that it should rank as a subspecies and not as a variety. 

 It is not always easy to separate it from ascrva. Specimens from 

 Golden and Howser, B. C, are very dark and much like aserra, except 

 that the head, even in the smaller workers, is not darker in color than 

 the thorax. The emargination of the clypeus is, however, extremely 

 feeble in these specimens, even feebler than in aserva and ruhicunda.
