A handsome and interesting species, distinguished as well by 

 its general shape, which is more elliptic and convex than usual, 

 as by its polished surface. The head is oblong and, with the 

 exception of the mouth, the parts of which are of a deep brown, 

 of a bright metallic green, divided longitudinally by a streak of 

 copper colour. The thorax is rather longer than broad, round 

 in front and flat behind, and finely punctured all over ; it is of 

 a brownish metallic colour bordered laterally with bright green. 

 The elytra are of the same colour as the thorax, the same bright 

 green stripe running along tlie sides ; the margin, properly speak- 

 ing, is deep brown ; the elytra are impressed with rows of line 

 indistinct punctures, and with the usual series of larger setigerous
