the labrum is much elongated and sulcate in front as in the Stenoglossce. The elytra 

 are deeply striated, without perceptible punctures and with convex interstices, they 

 are ovate in shape, widely margined in the middle of the sides, and there tinged 

 with rufous : the colour above is dark brassy-blue or greenish ; the body beneath is 

 pitchy-black, and the legs and antennae are clear reddish-testa.ceous.

 ticketed as from Batchian.

This fine species is distinguished by the long spine into which each angle of the 

 truncature of the elytra is prolonged in both sexes. The colour varies from piceous- 

 red with a brassy -lustre, to brilliant coppery with bi'assy reflections, and sometimes 

 the head and thorax are glittering brassy-green wliilst the elytra are cupreous.

Scarcely differs from C. spinipennis, except in the absence of spines from the 

 angles of the truncature of the elytra ; in general appearance it much resembles the 

 coppery species of Anchomenus and Colpodes. The head is small, triangular, and 

 narrower than the thorax, which again is much narrower than the elytra. The 

 general colour above is shining coppery, with the head and thorax generally of a 

 green aeneous tint. 



Common at Ega.

A very handsome species, distinguished by the smooth surface and brilliant 

 green hue of the elytra. The head is rather large, but not quite so wide as the 

 thorax ; the labrum is not much elongated but nearly square, notched in the middle 

 of its front edge ; the antennas are robust, but the joints remain cylindrical. The
