This si)ecie's is most closely allied to deulschi Zetterstedt, hut that 
species is hut slightly shining, and the abdomen opaepie black, through 
the [)resence of distinct pollinosity. The cheek in deutscJii is also said to 
be linear and no mention is made by Becker of the ]>resence of strong 
bristles wdiich are a feature in the present species. iNIelander records 
deutscld from Alaska and Washington. I have not seen American ex¬ 
amples of the latter.
