Oresson based his description of this species upon two females 

 from Colorado, which differed from one another in size and also 

 to some extent in their maculation. He says that on one specimen 

 there were obscure dusky areas on the anterior apical corners of the 

 clypeus, but he failed to state on which of the two specimens these 

 dusky areas occurred. On both of these specimens the sixth tergit€ 

 was entirely black. Handlirsch based his description of this species 

 on a single female from Illinois and this specimen had the sixth 

 tergite maculated. Fox described a male from Illinois that he con- 

 sidered the male of this species. It was this male that I made the 

 type of Bennhix foxi Parker, whose description appeared in my pre- 

 ceding paper on this group.** In the collection of the United States 

 National Museum are females from Colorado that answer perfectly 

 to Cresson's description of the larger of his two specimens upon 

 which the species was based, and in the collection are also males 

 from Colorado that so closely resemble these females as to warrant 

 the assumption that they are males of this s])ocies. On all these 

 specimens, both males and females, the fasciae on the tergites are 

 very light, almost white. In the collection, with the sixth tergite 

 conspicuously maculated, are other females that I have referred to 

 this species, some of which are similar in color to those light forms 

 mentioned above and some are of rich golden yellow. It is possible 

 that I am including here specimens of more than one species, but 

 the limited material at hand and the absence of males to associate 

 with these extensively maculated females does not permit a splitting 

 of this group into distinct species.
