Mr. Crotch (loc. cit. p. 136) states that M. Allard, to 

 whom he submitted his SitoneSj pointed out two or three of 

 this species. 



It is allied to S. jiave&ceiu ; and, as pointed out by me, 

 Ent. Monthly Mag. vol. i, p. 230 (note), may be known 

 from that species by its smaller size, more deeply furrowed 

 head, rather more prominent eyes, more elongate and more 

 distinctly punctured thorax, unspotted head and thorax and 

 more strongly punctate-striate elytra.

Mr. Sharp has taken in the island of Arran, in August, 

 1864, a specimen of a Sitones differing from camhricus in the 

 colour of its antennae, which are rufo-testaceous, with the 

 club darker, — the broad sulcation of its rostrum, — its longer 

 and narrower build, especially evident in the thorax, the less 

 coarse punctuation of its upper surface, and the nearly white 

 scales of its underside. Mr. Sharp has no doubt that this 

 insect is the S. cinerascens of Allard, of which mention has 

 been made in the " Annual " for the present year. 



Another example has subsequently been detected in Mr. 

 Crotch's collection.
