length and are rather finely and closely punctured externally ; the 

 metasternum a little more sparingly towards the middle, where 

 the hind coxae are almost impunctate. The ventral segments are 

 punctured almost as the metasternum. The ventral series consist 

 of stout hairs and are well defined. The hind femora are decidedly 

 wider than the intermediate, their inner apical angle very obtuse 

 and scarcely prominent. The uppermost tooth on the anterior 

 tibiae is small but sharp.

Labrum decidedly overtopping level of clypeus which is gently 

 emarginate in front ; " trilobed outline " of head having the lobes 

 feebly convex, the middle one about half as wide as the others ; 

 clypeal suture fairly defined, straight, and impressed, clypeus 

 forming an even surface with the rest of the head. Prothorax 

 nearly twice as wide as long down the middle and more than half 

 as wide again at base as at front which is moderately concave with 

 sharp moderately produced angles ; the sides are evenly and gently 

 arched, most divergent immediately in front of the base ; the hind 

 angles viewed from above appear very ill-defined but not quite 

 rounded off; the base is bisinuate, widely and feebly lobed in the 

 middle ; the elytra (in the example before me) have no trace 

 whatever of striation ; their transverse wrinkling is coarse and 

 rather conspicuous; the lateral fringe is much abraded in the 

 example before me but evidently is not in a fresh specimen carried 

 round the apex in any conspicuous manner ; the apex has an 

 obscure membranous border. The puncturation of the whole
