CeutJiorrhynchits.'] RHTXCHOPHORA. 351 



southern counties ; not common in the Midlands ; I have never found it in the Mid- 

 land counties myself nor is it in Mr. Blatch's list ; Mr. W. Garneys has, however, 

 taken it'at Bepton ; Mablethorpe, Lincolnshire; Filey, Yorks; Holy Island ; North- 

 umberland and Durham district; Scotland, common, Solwav, Tweed, Forth, Moray 

 and probably other districts ; Ireland, Waterford, and near Belfast. 



This species somewhat resembles C. melanostictus, but may be 

 known by having the thorax more narrowed in front, by the absence of 

 a distinct pattern of scales on the elytra, and also by the upright 

 pubescence, which is distinctly visible if viewed sideways. 



C. ffeographicusj Goeze (echii, F.). A large and conspicuous 

 species, black or fuscous black, with the underside thickly clothed with 

 greyish-white scales, which on the upper surface are arranged in dis- 

 tinct slender lines forming a pattern ; the thorax has the posterior 

 margin and three narrow lines white, and on the elytra the most con- 

 spicuous line is an oblique flexuous one arising at the base of the 

 suture ; rostrum long, antennae in part ferruginous ; thorax about as 

 long as its breadth at base, constricted before apex, very closely punc- 

 tured, without distinct central furrow and with lateral tubercles, sides 

 notched in front ; elytra with fine striae and broad flat interstices, and 

 with small spines at sides and towards apex j legs stout, femora strongly 

 toothed. L. 4f-5f mm. 



On Echium vulgare and occasionally on thistles; the larva lives in the roots of 

 the plant and undergoes its transformations in a cocoon below the surface of the 

 earth ; the perfect insect appears in June ; locally common : London district, Kent 

 and Surrey, not uncommon ; Mickleham ; Caterham ; Whitstable ; Deal ; Dover ; 

 Sandgate ; Pnrfleet, Essex ; Hastings ; Amberley ; Southampton ; Portsmouth dis- 

 trict ; Bristol; Rodborough, Gloucestershire; Swansea; ^Northumberland and 

 Durham district, rare; Scotland, very rare, Tweed and Forth districts. 



This species is the largest of the British Ceuthorrhynchina and 

 cannot possibly be mistaken for any other. 



C. pollinarius, Forst. Black, or brownish-black, underside 

 clothed with yellowish-grey scales, upper side with rather scanty cine- 

 reous and brownish scales which are much thicker in quite fresh 

 specimens, antennae and tarsi ferruginous; head depressed between 

 eyes, antennae inserted before middle of rostrum ; thorax moderately 

 long, narrowed and broadly constricted in front, closely and strongly 

 punctured, with a deep central furrow and very strong sharp lateral 

 tubercles ; elytra broad, with strongly marked shoulders and fine striae, 

 interstices flat, rugose ; ninth interstice entirely and the rest at apex, 

 muricate ; legs long, femora strongly toothed. L. 4 mm. 



Male with the posterior tibiae armed with a small hook at apex and 

 the last ventral segment impressed with a small fovea. 



On nettles ( Urtica dioica) abundant and generally distributed throughout the 

 kingdom. 



C. viduatus, Gyll. (s.g. Tliamiorohis, Thorns.). Black, dull, upper
