drawn up the appended comparative table of the differences between 

 the two species : 



C. MiNUTUS, Sturm. C. punctulum, Gyll. 



Last ventral abdonniial segnent Last ventral abdominal segment 



distinctly more rugose tlian preceding alulaceous, but not more rugose than 



segments ; pubescence of abdomen preceding segments ; pubescence of 



longer and more thiclily placed in abdomen shorter, not more thickly 



middle of apex of last segment. placed in middle of apex of last segment. 



Apex of elytra somewhat pointed ; Apex of elytra very bluntly 



upper-side thinly covered with moder- rounded ; upper-side more closely 



ately long pubescence, which is more covered with short pubescence, which 



thickly placed on head. is much more thickly placed on head. 



Size larger: length, 1— U mm. Size smaller: length, i— j mm. 



Colour of disc of elytra usually Colour of disc of elytra usually 



lighter (brown). darker (black). 



The last joint of the antennae m O. minutus is said to be "much 

 longer than broad," that of G. ^ninctulum " as long as broad " ; this 

 distinction is not very apparent. The colour of the elytra is sometimes 

 wholly ferruginous in both species. 



C. nitidus, Steph. (Manual, p. 107), is probably C. punctulum, 

 Gyll., and is so regarded in Stein and Weise's Catalogue, 1S83, 

 although this synonymy is dropped in the European Catalogue of 

 1906, probably in consequence of Fowler's remarks in Brit. Col., 

 vol. iii. 



With regard to the pubescence on the upper-side of C. miniitus, 

 Sturm, I find this a frequent stumbling block, and often have this 

 species sent me as C. armadillo, Be G. ; the best distinction for 

 separating this latter species and C. puhescens, Kedt., is their alutace- 

 ous upper-side, whereas, both C. minutus, Sturm, and C. punctulum, 

 Gyll., are smooth and shining. 



Mr. Newbery, I may say, has taken C. punctulum at Highgate, 

 and Mr. Champion has it from Guildford, Woking, and Ashtead, 

 Surrey ; Cobham, Kent ; and Soham, Cambs. This species, therefore, 

 is widely distribiited. Mr. Donisthorpe records it from Chattenden, 

 Kent.
