Eumenes belfragei sub species, aureus new subspecies. 



Female. — Like the typical belfragei in structure, but differing 

 strikingly in color, due to the replacing of black and ferruginous largely 

 by yellowish-ferruginous and yellow. Black confined to the dorsal 

 aspect of the head, middle of the mesonotum, base of the petiole, anterior 

 margin of the mesostemum, posterior margin of the epimeron and 

 base of the petiole; ferruginous on the mesonotum, petiole and second 

 segment of the gaster, grading to yellowish-ferruginous on the sides and 

 ventral aspect of the thorax; a narrow oblique band on either side of 

 the second segment of the gaster, ferruginous; yellow markings the same 

 as in the typical belfragei, except that the entire clypeus, the greater 

 part of the second segment of the gaster and the following segments 

 are yellow.

Crucifera Group. 



This group would fall in Saussure's division Pachymenes, and 

 includes those species with the gaster depressed, the petiole 

 very broad and campanulate, and the wings large. The group 

 can not be distinctly separated from the fraternus group; boll if or- 

 mis is distinct from the species of any other group, but steno gaster 

 resembles globulosus, while sternalis might be confused with 

 coloradensis.

This species superficially resembles crucifera, but is much 

 larger, the gaster is proportionately wider and the second 

 segment more depressed.
