 S the i^edicel is as long as the first and second funiclar joints together, 

 pale at tip, the first funiclar joint very minute, the club 6-jointed, cylin-

 from the margin of the eye. Anteunti? 10-jointed, very long and slender, 

 subclavate, reaching beyond the middle of the abdomen ; x)edicel slender, 

 nearly as long as the first and second funiclar joints together; funiclar

 long as thick. Thorax polished, with two distinct furrows, mesopleura 

 deeply impressed at the middle; scutellum highly convex; metathorax
