Dillsboro, N. Car., Sept. 12 (Brimley). The recorded range 

 extends from New England west to Colorado, north of latitude 

 40 c , the North Carolina specimen, determined by Knight, be- 

 ing the first one known from the south. New Jersey specimens 

 received as fraternus from Davis and others so named from 

 North Carolina have the scutellum yellow, and Knight states 

 that : "Judging from a large amount of material from Colorado 

 and the eastern states, fraternus Uhler appears to be nothing 

 more than a variety of obscitnts Uhler."
