100 COLEOPTERA. 



97. Ceuthorhynchus inornatus, Waterhouse, Proc. 



Ent. Soc. 3 June, 1861, Zool. 7615 (1861), 



described. 

 Allied to C. sulcicollis, Gyll., from -which it may be dis- 

 tinguished by the pitchy-red colour of its tarsi, and by the 

 under surface of the body being very sparingly clothed with 

 the white scales so conspicuous in the latter species. In the 

 male of sulcicollis^ also, the penultimate abdominal segment 

 underneath has two approximated small tubercles, and the 

 last segment is concave in the middle, the concavity being 

 bounded by a slight ridge ; whilst in inornatus the penul- 

 timate segment is simple, and the concavity of the last seg- 

 ment is bounded by a conical tubercle. 



Taken by Mr. Waterhouse at Highgate, Box-hill and 

 Northfleet, always on Erysimum alliaria ; afterwards by 

 Dr. Power, Mi*. Brewer and others, on the same plant. 

 C. sulcicollis, which feeds on Erysimum officinale^ appeals 

 never to accompany this species.

 If S. granarius be allowed as an English species, the 

 present also must be included in our lists, having become 

 naturalized, and being abundant in many parts of the 

 country though of course originally introduced from the 

 East.
