CG. horridus, F. (spinosus, Goeze). A large and conspicuous species ; 
pitchy-red, or ferruginous with the elytra, antenne and legs lighter, 
underside with comparatively scanty greyish scales; forehead depressed, 
with rather thick greyish scales, rostrum rather long, striate ; thorax 
spinose, notched at sides in front, very rough, coarsely and closely 
punctured, constricted narrowly before apex, with an obsolete central 
furrow, sides raised and rounded ; elytra broader than thorax, with 
rather deep striz, interstices raised and bearing single rows of strong 
black and white sete, with hairs intermixed ; legs moderately long, 
intermediate and posterior femora rather strongly toothed. L. 33- 
5 mm.

CG. distinctus, Bris. I have hitherto regarded this species as merely 
a variety of C. marginatus, and Dr. Sharp has included it under the 
latter species in the second edition of his catalogue ; the sole point in 
which it appears to differ from C. marginatus is the sub-generic 
character that the funiculus of the antenne is six-jointed, and Mr. Rye 
(Ent. Annual, p. 50) mentions the fact that he had captured a specimen 
with six joints to one funiculus and seven to the other, which forms a 
sort of “ reductio ad absurdum ” of the whole question ; I have followed 
Bedel in retaining the species in its present position ; this author regards 
it as “* facile A confondre avec le C. punetiger dont elle a tout le faciés ;” 
T must say that even after seeing M. Bedel’s work, I still feel that the 
question of this difficult little group (C. marginatus and its allies) is far 
from being satisfactorily settled. L. 2-3 mm. 
The species has been taken at Horsell and Weybridge by Dr. Power and also by
