 cariniform elevation along the middle and three small callosities 

 placed in an oblique row along each side. Scutellum closely 

 covered with white pubescence. Elytra closely and strongly 

 punctured from the base to a little past the middle, feebly towards 

 the apex ; the punctures each witli a short, decumbent grey hair.

In general form, more especially in the shape and structure of 

 the prothorax, this species greatly resembles 0. zci/lanicHm.V^'hite, 

 but differs from it in the shape and colour of the femora. It 

 differs from C. sim2)lea\ Gyll., by its narrower and more elongate 

 prothorax, and its more strongly thickened and darker coloured 

 legs.

Brownish testaceous ; antennae and legs yellowish. Head rather 

 densely covered above with pale yellowish pubescence. Antennse a 

 little longer than the body in the S , not quite so long as it in the $ ; 

 third joint not longer than the first, distinctly louger than the

 glabrous, the intervening spaces sparsely and irregularl}- punctured. 

 Scutellum covered with pale fulvous pubescence. Elytra closely 

 and strongly punctured from the base to the middle, the punctures 

 nearest the base somewhat granulate ; less strongly punctured 

 behind the middle, the punctures become gradually feebler as they 

 approach nearer to the apex ; the punctures also carry eacli a pale 

 decumbent seta. Eemora fusiform-clavate, thickened gradually

This species has been generally recognized as the one described 

 by Gyllenhal under the name given above. But it corresponds in

 sometimes twice as long as the body — "Antennce interdum corpore
