 punctured, the pubescence rather long, sparse but distinct; elytra at 

 the sides much longer than the sides of the prothorax, the suture 

 scarcely shorter than the median line, the punctures fine, subasperate 

 and only moderately dense, the pubescence distinct; abdomen nearly 

 as wide as the elytra, narrowing slightly behind the middle, the punc- 

 tures fine, moderately close-set basally but becoming gradually very 

 sparse on the last four segments, the punctures of the impressions 

 slightly larger and rather less sparse than the others, and, as

 joint three -fifths wider than long, the second and third elongate, the 

 former but slightly the shorter, prothorax large, less transverse, two- 

 flfths wider than long, moderately narrowed from base to apex with the 

 sides strongly arcuate, the base arcuate as usual, the angles very 

 obtuse but evident; elytra only two-fifths wider than long, the sides as 

 long as those of the prothorax, the suture three -fourths as long as the 

 median line, the punctures fine, feebly asperate and well separated; 

 abdomen nearly as wide as the elytra, parallel and straight at the sides, 

 not at all narrowed posteriorly from the base, finely, very sparsely 

 punctate ; hind tarsi distinctly shorter than the tibiae, the basal joint 

 not quite as long as the next two combined. Length 3.8-4.4: mm.;
