Much more elongate. Black, shining. Thorax with deep, distinct 

 median line and two bristle-bearing punctures on sides just in front of the 

 middle. Elytra granulate and punctate as in furvus, the striae deep ; in- 

 tervals convex; humeral carina reaching beyond middle. Length 15-18 mm.

 more strongly reflexed than in any of the preceding species. Elytral striae
