Antenna:' setaceous, 3o-jointed, piceoiis, the first two joints rufous. 
Flagellum with a whitish annulus that occupies about seven joints. 
The basal joints are long, four or five times as long as thick, while 
those after the annulus become much shorter, those nearer the apex 
being only one-half longer than thick. Head above and behind highly 
polished, occiput and cheeks faintly ])unctate. Vertex with a finely 
impressed longitudinal line. Eyes rather small, oval, about as broad 
as the cheeks. Mandibles slender, edentate, black at tips. Palpi pale

punctured; trilobed, the ])arapsidal furrows crenulate anteriorly; 
behind, the space between them is roughly rugose. Scutellum small, 
narrow, with a broad rugose depression at its base. Metathorax 
coarsely rugose reticulate, the reticulations defining rather irregularly 
six longitudinal carina^ on the posterior three-fourths. Metapleurae 
more finely rugose. Abdomen as long as the head and thorax, clavi-

punctate, with two prominent long'itudinal carinae on the basal half
