Rye, I. c. 



Determined by M. Brisout from two specimens in Mr. 

 Crotch's collection. 



It is allied to M. erythrofus^ but rather wider and more 

 convex than that species, with closer punctuation, wider 

 tibiae, and a bidentate projecting transverse keel at the ex- 

 tremity of the last abdominal segment in the male.

 fumntus, E. C. Rye, I. c , vol. vi, p. 257, nee Gyll. 

 Several examples of this fine species were taken by Mr. T- 

 J. Bold in Northumberland ; and one of a pair of these, for 

 which 1 am indebted to the accustomed liberality of that 

 gentleman, was returned to me by M. Brisout as C. fiimatus, 

 and brought forward by me under that name. The other 

 specimen was shortly afterwards returned to me by Dr. Kraatz 

 as his C. validuSf with which Mr. Bold's insect accords 

 much better than with fumatus. Of our species, C. validus 

 seems most to resemble a very large example of the pallid 

 form (patnielis) of scanicus; from which it differs in its 

 thorax being more rounded behind the middle, with the 

 lateral denticle further removed from the anterior callosity 

 (of which the posterior margin is not acutely defined, but 

 merges in the space between the callosity and lateral denticle), 

 and longer, more parallel and more finely punctured and 

 densely golden- pubescent elytra.
