punctate than the thorax, and very feebly and indistinctly 

 striated, with the exception of the sutural stria, which is deeply 

 ini])resscd. The anterior tibia* are slightly widened towards the 

 extremity. 



^Vhere the characteristic breadth of the thorax is well deve- 

 loped, this species can be recognized by the base of the thorax 

 being a little wider than the base of the elytra, and by the elytra 

 narrowing backwards and becoming truncate : where this is less 

 conspicuous, the smaller size, narrower shape, the straight mar- 

 gins of the elytra, and their narrowing behind, distinguish it from 

 C. velox. From C. hadius, its smaller size, much lighter colour, 

 straight posterior margin of thorax not projecting backwards at 

 the posterior angles, sej)arate it ; and it is readily distinguished 

 from the following species (C. hrunneus) by the finer punctuation 

 of the elytra. 



Spread over all Europe, including Scotland and England, but 

 everywhere scarce.

This species bears considerable resemblance to C. pracox, is 

 of the same colour, but is larger, and in the male especially has 

 the elytra much more elongate. It has also the elytra very 

 deeply transversely strigose, and has seven distinctly impressed 

 irregular stria?, besides a deep sutural stria. 



Male. Pubescent, of a yellowish testaceous or pale brown 

 colour. The antennae are testaceous, slender, longer than the 

 head and thorax. The first and second joints are long, the first 

 a little shorter and thicker than the second ; the second, third 

 and fourth are about equal in length ; the fifth, sixth and seventh 

 arc all nearly of the same breadth and thickness, but each a 

 little shorter than the one preceding it ; the eighth is slightly 

 shorter than those on each side of it. The last three are thick- 

 ened ; the last is short and a little acuminate. The head is a 

 little darker than the rest of the body, and the mouth somewhat 

 lighter. The thorax is pubescent, smooth, not punctate, but 

 feebly granulose, broader than long, rounded on the sides, 

 broadest a little behind the middle, bisinuate at the base, with 

 the posterior angles projecting slightly backwards. The scu-
