The head is smooth and of a shining bluish black ; the thorax, 

 which has also a bluish tinge, is covered with coarse punctures 

 running into one another ; the medial line is scarcely traceable, 

 but the impressions on each side of the base are long and distinct. 

 The elytra are dull black with a subapical orange spot on each ; 

 they are striated and have the interstices flat. Their whole 

 sm-face is seen under a powerful lens to be closely punctured, 

 and covered with short decumbent hairs. The under surface is 

 of a pitchy black with the legs yellow.
