Hab. New Guinea. Collected by Mr. Wallace. 

 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 disc impressed 

 with a longitudinal groove ; surface smooth, impressed towards 

 the sides with shallow foveas ; 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 being slightly increased in width from their base to 

 the end of their second third ; thence to the apex they are 

 obliquely narrowed, the apex itself being slightly reflexed and 

 subacute ; upper surface convex, impressed below the shoulders 

 with three or four nearly obsolete foveae, each elytron with eleven 

 distinctly punctured, sulcate striae, the first very short, all the 

 others terminating just below the middle of the elytron ; posterior 

 two-fifths of the surface fulvous, irregularly punctured.
