mesial toeth. Tlie thorax gradually narrowed ia frout from the lateral tooth, vvliieh is 

 triangular as in O. carinatus; the incision at the posterior angles is also as in that 

 species. The elytra are rather more distinctly, and somewhat less closely, punctured 

 than in 0. gazella. 



The head of the female is as in O. gazella ; the thorax is relatively broader than 

 in that species, gradually narrowed from the lateral tooth to the anterior angles, 

 thus the form of the thorax is nearly that of O. bicolor, $ , but it ia rather more 

 narrowed in front.

This species closely resembles C. ajfflnis, but is darker in colour, more shining ; 

 the pubescence (only in the c? ) is rather less scale-like and more dense. The thorax 

 in both sexes has an a;neous sutural line, and an reneous stripe on each side towards 

 the sides. The male in the large variety has the mandibles furnished with a single 

 large tooth at the base, and between this and the apical teeth there are indications 

 of three or four small teeth, the foremost of them being most prominent; the sub- 

 apical tooth is broad and short, and between this and the apex of the mandible are 

 two or three small teeth. 



The smaller males have the basal tooth of the mandibles cmarglnate at its apex ; 

 between this and the sub-apical tooth tliere is sometimes a very small tubercle ; the 

 sub-apical tooth is acute, and not much larger than tlio three or four teeth which 

 follow it. 



The female palo castancous, with a spot on the middle of tlie forehead and 

 behind each eye blackish-soneous ; the punctuation is crowded. The tliorax has tliree 

 broad dark roncous stripes; the punctuation is thick and strong, less strong and more 

 close than in C. affitiLi. The elytra are very closely and somewhat strongly punctured, 

 less closely and less strongly than in C. ajpni.i ; the suture and the extreme margins 

 are seneous, and there is also an indication of a stripe on the disc of each elytron. 

 The whole insect is much broader, and less convex, than tlie female of C. ajjlnis.
