Hemispherical, very little longer than vide. Piceous-black above, red- 

 dish-piceous beneath, shining. Thorax without punctures, the hind angles 

 rectangular. Elytra as wide as long, each with eight entire rows of rather 

 coarse punctures, the ninth distant from the margin at base, but joining it 

 slightly behind the middle: intervals flat, smooth, the alternate ones with 

 a very few distant coarse punctures. Length 2.5-3 mm.
