 small, the second slightly the longer; the third and first joints of club 

 about equal, longer than the second, the club very gradually thickened 

 toward the tip, the joints, except the last, 1^ times as long as thick, 

 the last joint stouter and longer than the penultimate, ovate. In the 

 S the pedicel 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- 

 drical, the joints nearly of an equal length, about twice as long as 

 thick, the last conic, one-half longer than the preceding. Thdrax ovoid, 

 polished, the mesouotal furrows complete, distinct; the middle lobe 

 posteriorly extending slightly upon the base of the scutellum; no 

 tufts at the base of the lateral lobes. Scutellum transversely, convex,

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

 subclavate, reaching beyond themiddle of the abdomen ; pedicel slender, 

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

 joints slender, and merging so gradually into the club joints that the

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

 deeply impressed at the middle; scutellum highly convex; metathorax
