The basal three joints of the antennae are green, the rest black ; 

 the third is fully twice the length of the fourth. The upper part 

 of the head is deeply, closely rugosely punctured ; the centre is of 

 a darker bluer tinge, the sides are more brassy ; the lower edge 

 is . — * — ,-shaped and deeply excavated in the centre below the 

 keel ; the raised sides have large deep fovese. The front is much 

 more golden in tint than the vertex ; it is closely and minutely 

 punctured with some minute striae ; the orbits are deeply, irregu- 

 larly punctured. Thorax above strongly, closely, and uniformly 

 punctured ; the punctures on the post-scutellum are larger and 

 deeper ; its sides, above, project ; the middle fovea is large, and 

 wider than long ; the lateral are smaller, shallower, oval, and are 

 placed obliquely. The apex of the median segment has an almost 

 perpendicular slope ; the projecting sides are sharply pointed. The 

 upper part of the propleurae is coarsely punctured, the lower part 

 of it is deeply excavated, above it is rounded ; the base is straight, 

 the lower part has a straight, oblique slope, the centre of the 

 depression is closely, obliquely striated. The base of the meso- 

 pleurae is golden, closely and minutely punctured, and is distinctly 

 bordered on the outer side ; the rest is coarsely and deeply 

 punctured ; the lower part projects ; this lower part is separated 

 from the upper by an oblique row of more elongated in'egular 

 punctures ; the posterior lower part is fiuely and closely striated. 

 Metapleurae closely and minutely striated, they are golden in tint. 

 The coxae and femora are golden ; the tibiae are also tinged with 

 golden ; the tarsi are for the greater part black ; the hair is thick 

 and white. Wings fuscous-violaceous ; the uervures are deep 

 black, with a slight violaceous tinge. Abdomen green, blue in the 

 centre; the sides largely tinged with golden; the basal two 

 segments are uniformly punctured, but not very closely or deeply ; 

 the third is more closely and deeply punctured ; the punctures 

 become deeper and closer towards the apex ; there are 6 teeth ; 

 the foveae are deep and irregular ; the ventral surface is largely 

 brassy ; the last is broadly black round the edges.
