Elongate, convex, subparallel, shining metallic green. Head 

 fusco-violaceous, vertex metallic green ; antennae purplish black ; 

 vertex impressed with a deep longitudinal groove, which runs 

 downwards as far as the semicircular groove separating the epi- 

 stome from the face. Thorax transverse, twice as broad at the 

 base as long, sides nearly straight, gradually narrowed from the 

 base to the apex, more quickly narrowed immediately behind the 

 latter ; anterior angles produced, subacute, anterior margin con- 

 cave ; upper surface very slightly convex, middle of the disk im- 

 pressed with a longitudinal groove ; surface smooth, impressed to- 

 wards the sides with shallow foveae ; immediately within the lateral 

 border is a large, deep, irregular excavation, extending the whole 

 length of the side, its surface deeply impressed with large round 

 punctures ; colour bright metallic green, with a faint brassy tinge. 

 Elytra broader than the thorax, subparallel in front, but at the 

 same time slightly increasing in width from the base to the end 

 of the second third ; thence to the apex they are obliquely 

 narrowed, the apex itself being slightly reflexed and subacute;
