Two specimens ( $ 9 ) collected at Cranberry, Mitchell County, 

 North Carolina, June 10, at an altitude of 3250 feet by Mr. H. 

 W. Wenzel. I had looked upon D. fasciventris as the female 

 of D. elongatus, but through the kindness of Mr. Samuel Hen- 

 shaw I learn that Loew's type has five posterior cells. As the 

 male has never been described, and as the original description is 

 probably inaccessible to many I here redescribe the species.

 solete dorsal stripe of a darker shade; hairs yellowish, sparse, pleune 

 with blackish hairs. Abdomen brownish black, sparsely covered with
