Subquadrangular, rounded behind, cupreous or dark greenish ; 

 antennae, labrum, and tarsi light testaceous. Head very finely 

 striate, the striae all running towards a depression in the middle 

 of the head ; forehead rather widely punctate, closer towards the 

 lower portion of the face. Thorax widened in the middle, the 

 lateral margin bidentate, impressed with very deep punctures, which 

 are more crowded along the anterior margin, leaving an elevated 

 space exactly in the middle of the base either perfectly smooth or 

 with one or two impressions. Scutellum semiovate, impunctate and 

 shining, Elytra either dark cupreous or greenish with a purple 

 reflection round their edges each elytron with five or six elevated 

 and interrupted ridges on its surface, the space between which is 

 deeply punctured, the punctuation terminating in regular striae 

 towards the apex. Body beneath black ; the legs sometimes dark

 striate ; antennae very slender, with the first six joints flavous, the rest

 ted near the sides, but are impunctate. Scutellum closely punctured. 

 Elytra deeply rugose and impressed with large punctures and trans- 

 verse raised striae, besides which each elytron is also furnished with 

 a number of longitudinal short tubercules, which are situated as 

 follows, viz. one on the shoulder, and a second below it in an 

 oblique direction, four at a little distance from the shoulder running 

 down towards the apex, and two other rows closer towards the 

 suture, running parallel with the last one. Legs rather long for this 

 genus, ferruginous, as well as the last abdominal segments.
