Mentum ovate laterally from the base to two-thirds of the length, 

 constricted near the point of insertion of the palpi, thence sub- 

 obliquely ampliated towards the apical part, which is broadly but 

 not deeply emarginate, and fringed with dense somewhat bristly 

 hairs, the outer face is deeply and broadly foveate, and has very long 

 and very stiff black bristles, it is impressed in the anterior part and 

 convex thence towards the base ; the maxillae are long, robust, the 

 upper lobe is produced into three long, sharply falcate teeth on each 

 side, and has a pencil of long hairs at the tip, the last joint of the 

 palpi is fusiform, slightly truncate at the tip ; the mandibles are 

 long, flat, truncate at the tip, very densely ciliate inwardly, and 

 project slightly beyond the labrum which is horizontal, a little 

 shorter than the clypeus, transverse, a little attenuated towards the 

 apex, where it is slightly emarginate ; clypeus a little more than 

 twice as broad as long, straight in front, slightly rounded laterally, 

 head twice as long as broad not separated from the clypeus by a 

 suture, eyes moderately large, not quite evenly divided by the 

 canthus of the genae ; antennae short, nine-jointed, club as long as all 

 the other joints taken together ; prothorax narrowly marginate all 

 round, longer than broad, very little sinuate in front, rounded 

 laterally and also ampliate in the anterior part, and deeply emarginate 

 from about one-third of the length to the basal angle which is 

 slightly rounded, basal part obliquely prolonged towards the 

 scutellum, but not angular in the centre, and narrow'er than the 

 elytra ; scutellum broad at the base, thence narrowed, long, shai-ply 

 acuminate at the tip ; elytra as broad as long, but short and barely 

 reaching the propygidium which is very broad, plane on the disk, but 

 with a conspicuous basal humeral callus, and a deep impression 

 between it and the outer margin which is somewhat rounded 

 laterally and more ampliated aiiove the mesothoracic epimera ; the 

 latter are greatly developed, but do not project much beyond the 

 outer margin ; pygidium long, ovoid, sub-vertical, convex in the 

 apical part ; abdomen compressed laterally, the first five basal 

 segments fused, penultimate one as broad as the four preceding and 

 a little broader than the apical one ; metasternum moderately in-oad, 

 mesosternum very small ; legs moderately long, posterior femora and 

 tibicU robust, somewhat short, the intermediate and posterior tibiae 

 with two conspicuous apical spurs and with transverse ciliate rows
