margins of the thorax and base of the elytra are of the same 

 nature as in G. e.vcavatus^ but much narrower ; and the thorax 

 is rather strongly narrowed behind. The epipleurte of the 

 elytra are more feebly rugose-punctate than in C. excavatus ; 

 and the sides of the metathorax and basal ventral segments, 

 instead of being sculptured as in that species, are smooth.

The species described in this paper were received by the 

 British Museum in a collection recently brought to this 

 country by the Rev. W. Deans Cowan, to whom we are 

 already so mucl) indebted for numerous interesting novelties. 

 They were chiefly collected a few miles to the north of Fiana- 

 rantsoa.

The thorax is shining, finely and not very thickly punc- 

 tnred ; the yellow colour occupies about half the surface, 

 leaving the narrow lateral margins, the base, and a cross on 

 the disk black. Scutellum black and smooth. There is a 

 yellow spot on each epimeron. Elytra dull and velvety, each 

 Avith nine yellow spots, viz. two between the suture and the 

 first costa, three between the first and second costge (two near 

 the base and one beyond the middle), three on the sides, and 

 one at the apex. The pygidium is chiefly yellow ; but the 

 base, the middle, and a small spot (in the yellow) on each 

 side are black. There are two transverse yellow spots at the 

 side of the third, fourth, and fifth abdominal segments, and 

 one on the side of the first and sixth segments ; there is one 

 below the anterior angle of the thorax, and three at the sides 

 of the sterna. 



From another source there is in tlie British Museum an 

 example which has the thorax black, with ten yellow spots,
