ioints sliglitly dilated on the lower side, the second joint as 

 long as the third ; the scape sparsely covered with white 

 hair; the flagellum bare. Head shining; the face, cly pens, 

 and labrum thickly covered with silvery hair; the front and 

 vertex strongly and closely punctured except near the eyes, 

 and thickly covered with long fuscous hair. Mesonotum 

 strongly and closely punctured ; the parapsidal furrows only 

 indicated at the base. The scutellum is not so strongly 

 punctured as the mesonotum ; on the outer side of the post- 

 scutellum is a distinct slightly convex keel. In the centre of 

 the basal area of the median segment are two stout straight 

 keels ; the rest of it with stout oblique keels; the apex of the 

 segment is almost perpendicular and is furrowed down the 

 middle; in the middle, on either side, are three stout oblique 

 keels, ending at the edge in three small arese. Pro- and 

 mesopleurge smooth ; the tubercles fringed behind by white 

 pubescence ; on the base of the mesopleurse is a wide deep 

 furrow which is bent in the middle ; the longitudinal furrow 

 is narrow : the base of the metapleurge is depressed ; on the 

 lower side is a narrow oblique furrow ; the apex is irregu- 

 laily stoutly reticulated ; in front of this part are some longi- 

 tudinal keels. Mesosternum shining, smooth, the central 

 furrow shallow, wide, at the base closely transversely striated. 

 Legs black, covered with longish white hair; the calcaria 

 fulvous. The stigma and nervures are fuscous, the former 

 with a more rufous tint ; the first cubital cellule is about one 

 half the length of the third ; the first recurrent nervure is 

 received in the basal fourth of the cellule, the second is inter- 

 stitial. Abdomen smooth and shining ; the narrowed part of 

 the petiole longer than its dilated apex and the second 

 segment united, smooth, its sides covered with long white 

 hair ; the second ventral segment has a deep furrow at the 

 base, this furrow occupying the entire base, and at the sides 

 is covered with white hair ; the apices of the third and fourth 

 ventral segments are fringed with longish hair.
