sparse on the disc and distinctly smaller than those of the striae, 

 becoming closer, as large as those of the striae and granulate near 

 the declivity and on the sides; the declivity very steep, almost as 

 in sparsus, shining, sparsely but strongly punctured; the suture 

 raised, the declivital face somewhat circularly flattened and rather 

 deeply and broadly sulcate on each side, with three small, acute 

 teeth on each side, situate just within the rather ill-defined, crenu- 

 late, lateral margin of the declivity, the ventral acute margin 

 formed by two crenulations on each side and absent near the 

 suture. 



The male has the front convex, rather coarsely punctured, 

 more sparsely behind, rather densely towards the epistoma, the 

 punctures slightly granulate, sparsely hairy; the pronotum without 

 the fringe of long hairs from the front margin; the elytral declivity 

 deeply concave, with the 2nd and 3rd teeth of each side forming 

 part of the lateral margin and very large, stout, incurved and 

 acute.

 clcser on the epistoma; the antennal club slightly longer than 

 wide, obliquely truncate en the distal half, with the distal seg- 

 ments showing from the upper side at the apex, the sutures pro- 

 curved, the sutures of the under face on the distal half and slightly
