44 COLEOPTERA. 



taken by my fiiend Mr. H. Montague, in the early part of 

 the summer of 1867, at Freshwater, Isle of Wight, and 

 now in my collection. 



This capture is most interesting to us, not only on account 

 of the species having been originally described from a British 

 example sent to Schonherr by the late Mr. Walton, but be- 

 cause the genus appears to be considered exclusively South- 

 European, — Seidlitz's only locality for our insect being the 

 Sierra Nevada, in Spain {Stenus Kiesenivetteri will doubt- 

 less here suggest itself). I remember being gravely told 

 that C. socius was truly a Cape of Good Hope insect ! 



Walton must through some error have repudiated the 

 specimen quoted by Schonherr, for there was a second 

 (badly abraded) example of the insect in his own collection, 

 wrongly labelled. This is now in Mr. G. R. VVaterhouse's 

 collection. I observe (in addition to his note upon this 

 species in the Stettin. Ent. Zeit. quoted by Seidlitz) that he 

 refers to this species in his " Notes," p. 87, under the head 

 of Omias sulcifrons, where no one would certainly ever 

 think of looking for it. He there states that the specimen 

 he gave to Schonherr was the only one he had seen, and that 

 he thought it came into his possession with the collection of 

 the late Mr. Millard of Bristol, but was equally ignorant of 

 its history and locality. 



Of our Rhynchophoraj the only species at all resembling 

 C. SOCIUS is Trachyphloeus squamulatus; from which its 

 larger size, longer and less suddenly rounded elytra and 

 smaller thorax, of which the sides are evenly rounded, will 

 readily distinguish it, apart from generic characters. 



The antennal grooves are pit-like, irregular, conspicuous 

 from above ; and, in the male, the scape of the antennae is 

 suddenly and angularly dilated close to the base, and curved. 

 In fresh specimens the thorax has the sides and a middle 

 line yellowish, and the elytra densely clothed with scales,
