Antennae as long as the body ; the middle of the llagellum 

 is broadly white. The face is rugosely punctured, almost 

 reticulated ; the clypeus is smooth and shining, roundly convex ; 

 the curveJ keels on the lower part of the vertex are few in 

 number and stout. Mandibles black ; the palpi white. Mesono- 

 tum smooth and shining, except on the apex of the middle lobe, 

 which is transversely striated. The scutellar depression is large

 obscure brownish ; the post-scutellum is white. The median 

 segment at the base is smooth and shining ; the rest of it, from 

 the keel, is closely transversely striated; its apical slope is 

 white ; this white band is directed broadly backwards in the 

 middle. The upper half of the propleura? is closely, longitudinally 

 reticulated, the lower strongly longitudinally striated. Meso- 

 pleura±, except in the middle behind, strongly longitudinally

 smaller and closer ; the metapleurae, from the oblique keel,
