Broadly ovate, convex, bright golden-green ; a longitudinal line 

 on the vertex, the narrow limb of the thorax, dilated at the basal 

 margin, the extreme outer border of the elytra, the suture, a 

 transverse line in front and a short vitta behind near the outer 

 margin, bright metallic-blue; these markings are all more or less 

 bordered with metallic-green. Head smooth, face sepa'rated from 

 the clypeus by a deep transverse groove, front with a longitudinal 

 grooved line, which runs downwards to the middle of the trans- 

 verse groove ; antennae bluish-black, the basal joint and the under 

 surface of the two or three following joints fulvous. Thorax 

 more than twice as broad as long ; sides rounded, narrowed in 

 front, nearly straight behind ; surface very faintly and minutely 

 punctured ; remotely scattered here and there are some deep but 

 fine punctures. Scutellum purple. Elytra convex, smooth and 

 shining ; sides transversely impressed below the shoulder ; each 

 elytron with eleven regular rows of punctures, the first abbre- 

 viated ; the suture, the extreme outer border, a transverse band 

 in front, commencing at the outer extremity of the transverse 

 depression and extending inwards as far as the third stria from 

 the suture, and a short vitta behind the middle, placed on the 

 outer disk, bright metallic-blue. Beneath bright purple, legs and 

 abdomen marked with coppery-gold. 



This beautiful species, which was not taken by Mr. Wallace 

 during his expedition to New Guinea, is the only insect of the 

 genus found, according to my present knowledge, in the Malay 

 Archipelago.
