black, the femora black in the middle ; wings hyaline, the 

 nervures obscure testaceous. Antennae a little shorter than 

 the body ; the third joint twice the length of the fourth ;. 

 the 4 — 8 subequal, but becoming very slightly longer, and 

 of equal width, and about one-half longer than broad. The 

 5 -jointed club sub-abrupt, the ninth joint being distinctly 

 thinner than the tenth, and shorter than it. Scutellum indis- 

 tinctly striolated laterally ; metapleurae opaque, pubescent. 

 Abdomen shorter than the thorax ; the hair fringe dense, 

 griseous. Wings large, the apex hardly incised ; the radial 

 cellule elongate, more than twice longer than wide ; the 

 second abscissa of radius twice the length of the first. 



Length ij^ mm. 



Compared with loitgipennis the antennae are shorter and 

 stouter, the club sub-abrupt and the wings can scarcely 

 be said to be incised.
