apex which is a.lutaeeous, the middle slijjhtly and broadly incised. 

 Front closely puncitured below, the pimctines closer and finer below, 

 where it is also opaque; above the antennae tlve punctures are stronger, 

 more distinct and more clo,sely separated, this being also the case with 

 the vertex, except in front of the ocelli where there is a smooth space. 

 Palpi testaceous, covered with white pubescence. Pronotum stronoly 

 punctured, except around the apex, the propleurae smooth, shining-, 

 obsciirely striated at the base, the striated part wider below. Meson o- 

 tuni broadly punctured in the center, the part inside the lateral furrows 

 smooth, the puncturation at the apex closer and finer. Rcutellum punctur- 

 ed like the base of mesonotum, more sparsely in the center; the post- 

 Bcutellum is moire strongly closely and uniformly punctured and mure 

 thickly covered Avith long fuscous hair than the seutellum. Metanoial 

 area slightly narrowed towards the apex, which is transverse; the 

 central keel does not extend to the apex, being about two-thirds the 

 length of the lateral; only the upper three striae on metapleiirae extend 

 from the base to the apex, the others are more irregular, wider apart, 

 and commence shortly behind the middle. The puncturation on the 

 mesopleurae is weak and sparse. Base of first abdominal segment finely. 

 sparsely punctured, the apex smooth with a wide, deep, closely, strongly 

 crenulated furrow in the middle of the smooth part; the puncturation 

 on the other segments becomes gradually stronger en the apex; that 

 on the pygidium is close, deep and strong, with smooth line down the 

 middle of the apical (slo,pe.

Black; the head densely covered with longish White pubescence, above 

 the antennae closely strongly punctured; the face weakly punctured, 

 the clypeus more strongly, its apex broad and transverse. Mandibles 

 with a rufous band before the apex. Palpi dark fuscous, thickly covered 

 with white pubescence. Base of pronotum distinctly bordered by a 

 stout keel, the part behind the keel depressed and stoutly closely cren- 

 ulated; the promiotum, except for a wide irregular -^urved space on the 

 apex, punctured but not closely or strongly; the propleurae smooth, 

 shining, aciculated below. M.&sonotum inside the furrows, strongly but 

 not very closiely punctured, outsirle the furrows snuioth. The scutellun 

 is more strongly and closely punctured; at the apex is a small smooth 

 s})ace, widened behind. Postsciutelluim closely rugosely punctured all 

 over, thickly covered with lomg fuscous pubescence. Metanotam with 

 three keels, the outer slightly converging towards the apex, the 

 central weaker towards the apex, its apical slope shagreened, densely 

 covered with white pubescence; the up]>eT half of the metapleurae 

 with five stout keels, straight at the base, curved at the apex; the 

 ■econd from the top is short. Basal segment of abdomen more strongly
