240 RHTNCHOPHORA. [CleOHUS. 



chiefly, but not, altogether, confined to districts near the coast ; Charlton, Whitstable, 

 Sheer'ness, Gravesend, Harwich, Great Yarmouth, Hertford; Bottisham, near Cam- 

 bridge; Dover; Hastings; Eastbourne; Portsmouth; Chesil Beach ; Bristol; 

 Swansea ; Erdington ; Knowle, near Birmingham ; Southport and Blackpool, Lanca- 

 shire ; Liverpool, common, sometimes in profusion, on the Crosby and Hightowu 

 Sandhills among thistles; Northumberland and Durham district; Scotland, mari- 

 time, rare, Forth district ; it probably occurs in. Ireland. 



C. albidus, F. (fasciatus, Mull.). Much smaller than the preceding 

 species, with which it agrees in having the second joint of the posterior 

 tarsi short, scarcely, if at all, longer than broad ; it may however he 

 known by its colour, which renders it one of the prettiest and most 

 conspicuous of our British Curculionidae ; black, with the thorax clothed 

 at sides and more scantily on disc with yellowish or whitish yellow 

 pubescence, elytra very thickly clothed with snowy pubescence, with a 

 broad space at shoulders, a waved uneven band about middle and a 

 patch before apex denuded ; rostrum short, with a central carina, which 

 is bifurcate in front ; thorax very uneven and irregularly rugose on disc, 

 about as long as broad, with sides straight and parallel ; elytra slightly 

 broader than thorax, with fine punctured striae which are concealed by 

 the pubescence ; legs pitchy, pubescent ; the male characters are the 

 same as in the preceding species. L. 7-10 mm. 



Sandy places : on Chenopodiacecs ; the larva has been found on Atriplex rosea 

 (Frosted Orache) and Chenopodium album (White Goosefoot), and the perfect insect 

 has occurred in abundance near Venice on Atriplex patula (Common Orache); the 

 species is extremely rare in Britain ; I have a fine specimen in my collection taken by 

 Mr. W. H. Harwood in the Colchester district in 1883 ; in Dr. Power's collection 

 there is a specimen, without locality, from the Rev. J. Laundy Browne (probably 

 from the Fen districts), and Mr. Samuel Stevens possesses a single example, received 

 by him from Mr. Salmon, taken at " Thetford, Norfolk ; " Stephens (Manual, p. 251) 

 gives as localities Norwich, Ipswich, Cromer and Portobello, near Edinburgh. 



C. nebulosus, L. (Letliierryi, Chevr.). Of about the size of C. 

 sulcirostris, but easily distinguished by the elongate second joint of the 

 posterior tarsi, which is distinctly longer than broad, and its darker 

 appearance, as well as by the reddish tinge which is usually apparent on 

 some portion of its body ; black, thickly but irregularly clothed with 

 ashy pubescence. ; rostrum uniformly pubescent, with a strong and broad 

 basal carina ; thorax about as long as broad, with the sides constricted 

 before apex, with a central abbreviated carina in front and the disc 

 strongly rugose, the rugosities and elevations being raised above the 

 pubescence ; elytra with rather strong punctured striae, and the alternate 

 interstices more or less elevated, especially at base, pube-cence much 

 variegated with oblique denuded fasciae and patches ; the tubercle towards 

 apex is also always denuded ; legs long, pubescent ; the pubescence on 

 the head and rostrum, the thorax, legs and more or less of elytra is 

 usually to a greater or less extent of a duller or brighter reddish colour. 

 L. 13-14 mm. 



In heathy places; at the roots of Ericaceae; in sand-pits, &c. ; rare; Eslier,
