The foregoing list of localities shows that subnuda is a boreal and 
alpine form like aserva, but unlike this subspecies confined very largely 
to the Rocky Mountains within the confines of the United States. 
As I have found no transitions between it and the typical rubicunda, 
I believe that it should rank as a subspecies and not as a variety. 
It is not always easy to separate it from aserva. Specimens from 
Golden and Howser, B. C., are very dark and much like aserva, 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 rubicunda.
