NEW BRITISH SPECIES, ETC., IN 1865. 107 



Wat. Cat., must be referred to the above species j and that 

 it is of very great rarity abroad, as here. 



This insect appears to be of the size of C. 2?olU7iarius, 

 but to have a longer, narrower, sub-conic thorax. 



78. Ceuthorhynchus rap^, (Gyll.) Schon. Syn. Ins. iv. 



part i. 547, 105; Redt. Faun. Aust. 805. 

 inaffectatusy Wat. Cat. nee Schon. 



Mr. Crotch remarks that Mr. Walton's suspicion as to 

 inaffectatus being specifically identical with Syrites has 

 proved correct; and that the insects lately known to us by 

 the former name (and formerly by the latter) are to be re- 

 ferred to C. rapce. 



This species occurs rarely near London; Mr. Pelerin 

 taking it periodically on the northern side, where (Totten- 

 ham) Messrs. C. & F. Waterhouse have also found it ; and 

 Mr. Sharp recently discovered it on the south, at Lee, on 

 Sisymbrium officinale j accompanied by C. assimilis. 



79. Ceuthorhynchus Alliari^, Brisout de Barneville, 



Ann. de la Soc. Ent. de Fr. 1860, 537. 

 inornatus, Waterhouse. 

 Mr. G. R. Crotch (Ent. ii. 179, 116) remarks that M. de 

 Barneville's name, being the oldest, must be retained ; and 

 that the specific identity of the two insects was pointed out 

 to him by M. de Barneville himself, who had seen speci- 

 mens from England. 



80. Ceuthorhynchus pilosellus, Gyll. in Schon. Syn. 



Ins. vol. iv. part i. 346, 94. 

 Mr. Crotch remarks that C. hispididus, Stevens, MS., 

 is equivalent to this species, which occurs in Spain and the 

 south of France.
