I thought at first that this was the male of N. pulsatillce, 

 but there are so many differences that it seems best to regard 

 it as distinct. In the table of Rocky Mountain species it 

 runs to G2, but runs out because of the rather small size 

 and red on scutcllum. It is known from N. vicinalis by its 

 smaller size, total absence of yellow on thorax, &c. There 

 seems to be some affinity with N. denliculata, Rob.
