Elongatus, niger, nitidus, palpis pedibusque rufi's ;' prothorac

 legs, and also the shape and sculpturing of the head and prothorax 

 are the same ; the elytra are shining instead of being sub-opaque, the 

 costa? are much more raised with the alternate ones 2, 4, 6 higher 

 than the others, and the narrow intervals very slightly punctate, the 

 second costa bears five deep, round impressions, and the outer margin 

 has a regular series of deep punctures.
