Black, polished, shining. Head smooth and polished, convex 

 behind ; labrum with a row of large punctures (from which spring 

 hairs) in front ; mandibles with a bisinuated keel, broadest in 

 the middle, running along the upper side ; antennae ferruginous- 

 brown, short, robust, compressed and dilated towards the apex ; 

 the first three and greater part of the fourth joints polished, the 

 rest dull pubescent, with a flat, polished line running up the 

 middle of the compressed sides, both above and below, nearly to 

 the end of the last joint; a narrow marginal ridge runs along- 

 each side of the head until it reaches behind the eye ; the two 

 frontal impressions are sinuate, each composed of two deep lines 

 which meet in front and extend in a sinuate manner backwards, 

 diverging gradually from each other; they are joined in front 

 by a straight transverse line : all these lines are impunctate. 

 The thorax is subquadrate, and has somewhat the form (in 

 miniature) of that of some species of Pasimachus (e. g. P. sub- 

 Icevis, Beauv.) ; it is smooth, shining, and impunctate ; the 

 dorsal median line is faint, and reaches neither to the front nor 

 base ; the two foveated lines at the base are placed nearly mid- 

 way between the dorsal line and the margin, but rather nearer 

 the middle; they are long, deep, well denned and narrow, 

 and at their base turn off towards the sides at a right angle, 

 forming a narrow ridge on the exterior portion of the base, 

 which is wanting in the centre, and which continues along the 

 lateral margins round to and past the anterior angles, and a 

 considerable distance along the anterior margin, but fades away 

 before reaching its middle; a deep channel thus runs along- 

 parallel and close to the margins of the thorax ; the prosternum 

 is rather broad, and slightly produced and expanded behind ; near 

 the termination of the expansion there is a sort of double depres- 

 sion, which leaves a narrow raised margin. Scutellum small, im-
