 between the angular tooth of the clypeal emargination and the gense, 

 and has a few hairs and a few fascicles of the same in centre and 

 at base; prothorax declivous in the anterior part, sharply carinate on 

 the upper side from the base where the carina is produced in a sub- 

 erect, triangular, very conspicuous tooth to near the anterior angle 

 which is sharp, the lateral anterior part is slightly diagonal, and 

 there is no deep impression laterally, only a moderately narrow space 

 edged by the discoidal carina ; the upper surface is covered with dis- 

 tinct tufts of black hairs more or less seriate ; elytra fitting against 

 the prothorax, ampliate behind the shoulders, very indistinctly striate, 

 and having on each side four conspicuous rows of tufts of black hairs, 

 and a rudimentary one along the outer margin ; pygidium with three 

 longitudinal rows of hairs.

 are not fringed with such dense and long black hairs.
