thorax and elytra bright metallic purjile ; these latter with a large 

 common patch in front, extending from their base to beyond the 

 middle, rufous. Head smooth, two basal joints of antennas rufous 

 (the rest wanting). Thorax concave-emarginate in front ; sides 

 obliquely produced, notched close to the anterior angles ; above 

 convex on the disc, smooth and shining, impunctate, impressed on 

 either side at the base, sides deeply and irregularly- punctured, 

 bright metallic purple. Elytra broader than the thorax, anterior 

 angles produced obliquely forwards, their apex obtuse ; sides 

 rounded, apex obtusely rounded ; above convex, hollowed on the 

 sides below the shoulder ; deeply punctate-striate, the suture and 

 three following interstices in front, together with the six nearest 

 interstices to the suture behind, longitudinally costate, rest of the 

 surface transversely costate ; the second interstice from the sutural 

 one sub-carinate, and sending just before its middle a branch to 

 the suture; lateral margin moderately dilated, its outer edge 

 slightly recurved ; its surface impressed with a double row of

 centre of the disc impressed with an indistinct longitudinal groove, 

 at the base of which, immediately in front of the basal lobe, is 

 a transverse groove ; sides obsoletely excavated, whole surface 

 minutely and remotely punctured, sparingly covered here and there
