Piceous, strongly shining, sides of pronotum, underparts of thorax, 

 and legs bright castaneous, trophi and antennae pale. Anterior 

 margin of head with a small denticle (in fresh specimens) each side 

 of the slight median emargination. Front sparsely and finely punc- 

 tured, its anterior two-thirds rather coarsely and transversely rugu- 

 lose, vertex more coarsely and densely punctured. Pronotum 

 apparently devoid of marginal setae, margin evenly curved from 

 middle point of base to broadly rounded anterior angles, marginal 

 groove fine and complete. Surface highly polished, set with punc- 

 tures of two sizes — very fine ones, which are evenly but not densely 

 distributed, and a few very coarse ones, which are more abundant 

 laterally. Elytral striae rather fine but deep, strial punctures well 

 marked, intervals smooth and flat, not subcarinate at apex, each 

 sparsely set with very minute punctures. Lateral margin low and 

 blunt, epipleura shining. Pygidium with the usual separation into 

 a basal, longitudinally grooved portion and an apical portion but 

 with the dividing line not carinate, apical portion convex and shin- 

 ing, minutely punctulate. Mesosternum and sides of metasternum 

 shagreened, median portion of latter, abdominal stemites and legs 

 virtually impunctate. Basal transverse row of pits on each sternite 

 fine but distinct. Anterior femur with trace of marginal groove only 

 on anterior margin near insertion of tibia, posterior femur without 

 marginal groove, posterior tibia without accessory spine. Length: 

 3-4 mm.
