narrow triangle. The head is rugose in front, densely granular 

 behind, with larger scattered granules, except upon the vertex. 

 The pronotum is densely granular at the sides and moderately 

 shining in the middle and there are tine, rather scattered, 

 punctures over the whole surface. The elytra are rather 

 oj^aque at the sides and behuid and shining in the middle 

 anteriorly, where they are distinctly punctured. The pro- 

 sternum is horizontally produced and fairly sharp. 



($. The black sutural border is very narrow. The head is 

 finely and densely granular and has an angular process on each 

 side behmd the eye. The pronotum is also finely and densely 

 granular, but rather less densely in the middle. The front 

 angles are rather sharply produced, the lateral angles are 

 sj^inose and the hind angles are acute. The elytra are finely 

 alutaceous, without distinct punctures. The prosternum is 

 produced downward as a sharj^ conical process. The front 

 tibiie bear two or three sharp lateral spines. 



Variation of the male. In small specimens the head is deeply 

 emarginate in front but without sharp edge or ridge. The 

 mandibles are shorter than the head, very broad at the base 

 and irregularly toothed to near the tip. In large examples 

 the head is very broad and its front edge forms a strongly 

 elevated broad gently curved ridge. The mandible bears a 

 sharp tooth directed obliquely forward at a little distance from 

 the base and a bifid process with a similar direction a little 

 before the end. The tip is strongly bifurcated with one or two 

 mmute teeth in the cleft.

Type in the Genoa Museum ; co-ty|i3 in the British jMuseum. 



One large and one small male specimen, kindly lent to me 

 by the Genoa Museum, evidently represent the constant and 

 inconstant phases res])ectively. Zang pronounced this species 

 identical with the Siamese C. mouhoti Parry, but the elytra, 

 in addition to the al)sence of any dilatation of tlio sutural 

 strip3 in the male, are more shhiing in both sexes than in that 

 insect.
