218 Mr. W. Bainbridge's Observations on 



This insect is closely allied to Diplognatha ; it appears to be a 

 form uniting Campsiura of Mr. Hope and Diplognatha of Messrs, 

 Gory and Percheron. The following characters distinguish it 

 from both. 



The head and clypeus are elongate and quadrate, the sides are 

 elevated and produced into two small teeth at the anterior angles. 

 The thorax is hexagonal, and the spaces between the angles are 

 subsinuate, a few large variolose punctures appearing at the sides ; 

 the thorax is depressed and much produced towards the scutellum. 

 The elytra are broader than the thorax, and much narrowed at 

 the apex, with the surface uneven. The shoulders are elevated 

 and impressed, deeply concave near the scutellum, and punctato- 

 striate ; the striae are indistinct and imperfect. The colour above 

 is pitchy red and very glossy ; beneath it is somewhat of a lighter 

 colour. The epimera are yellow% and the breast on each side has 

 a broad yellow spot, with a smaller one near the margin of the 

 elytra. The first four segments of the abdomen are also spotted 

 with yellow. The hexagonal sub-sinuated form of the thorax, 

 and the colours beneath, well characterize this species from any 

 other yet described. It may probably be considered the type of 

 a new genus.

Habitat in Sierra Leond, 



This remarkable insect at some future time will be (he type of 

 a distinct genus, it is closely allied to Stripsiphcr of Gory, and 

 for the present may be ranged with that genus. It was brought 

 to this country by Lieutenant Sayers.
