Elliptic, broad, flat, dee]) shining black, the whole of 

 the upper surface punctured, elytra deeply striate. 



Mandibles narrow, slightly curved, very finely rugose, 

 slightly depressed, each armed internally at the base with 

 a rather long horizontal tooth on a level below that of the 

 surface of the mandible. 



Head nearly twice as wide as long ; sides sub-parallel 

 posteriorly, slightly sinuate in front of the eyes, and 

 somewhat oblique in the remaining anterior portion ; 

 clypeus scarcely prominent, rather broad, strongly and 

 somewhat semi-circularly emarginate, so as to leave only 

 the two angular teeth ; finely rugulose in front, covered 

 with irregularly impressed points, these points stronger 

 and thicker in the j^ost-ocular region, nearly smooth 

 behind towards the occiput. 



Prothorax transverse, slightly narrowed in front, sides 

 rounded in their anteiior two-thirds, obliquely truncate 

 posteriorly ; anterior angles prominent and rounded ; an- 

 terior margin widely lobed in the centre, posterior margin 

 strongly bi-sinuate ; covered with a strong close punc- 

 tuation on the margins, finer and sparser on the disc, Avith 

 an irregular narrow smooth central space limited by 

 punctures similar to those of the margins. 



Scutellum with a few punctures on the margins. 



Elytra oval, margined, angular at the shoulders, each 

 with eight deep punctured stria3, of which the external 

 one is obsolete and only indicated by punctures, interstices 

 slightly convex, covered with a strong and close punctua- 

 tion, not however sufficiently strong to render the surface 

 opaque ; punctuation of the margins deeper and denser. 



Beneath strongly punctured at the sides and base of
