Ceuthorrhynchus.] RHYNCHOPHORA. 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 itat Repton; Mablethorpe, Lincolnshire; Filey, Yorks; Holy Island; North- 
umberland and Durham district ; Scotland, common, Solway, 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. geographicus, 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, antenne 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 strie2 and broad flat interstices, and 
with small spines at sides and towards apex ; legs stout, femora strongly 
toothed. L. 43-55 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; Purfleet, 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 seanty cine- 
reous and brownish scales which are much thicker in quite fresh 
specimens, antenne and tarsi ferruginous; head depressed between 
eyes, antenne 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 striz, 
interstices flat, rugose ; ninth interstice entirely and the rest at apex, 
muricate ; legs long, femora strongly toothed. L. 4 mm. 
Male with the posterior tibie 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.
