Tlie head is of a dark brassy green, punctured, and but 



slightly depressed in the middle ; the thorax is testaceous, finely 



punctured with a broad black central dorsal vitta, spreading out 



at the base, and an excised looking emargination at the base on 



each side of it. The scutellum is small, with a deep impression 



in the centre. The elytra are marked with 10 distinct strise finely 



punctured ; at the base are two rather pointed lobes fitting into 



the emarginations at the base of the thorax ; there is a coarsely 



punctured and somewhat rugose patch near each shoulder, from 



which proceed two rows of coarse punctures, the outer reaching 



the apex, the other about two-thirds of the length of the elytra, 



the apex is broadly bidentated and almost truncated. In colour, 



the elytra are testaceous, with a very narrow basal fascia, a broad 



medial fascia, and the apex blue. The body beneath is dark 



green with the exception of the sides of the prothorax, a patch 



on the metathorax, and the apical segments of the abdomen and 



the sides of the others, which are yellow.

 The whole upper and under surface, with the exception of the 

 elytra, are of a brilliant metalUc green ; the head is punctured and 

 canaliculated, the thorax is finely punctured, the dorsal line is not 

 distinctly marked, and the base on each side of the central line is 

 excised or acutely emarginated. The elytra are striated and finely 

 punctured, a row of coarse rugose punctures extends from the 

 shoulders down the middle of each elytron to the apex, which is
