Cryptorrhynchus. ] RHYNOHOPHORA. 329 
species, are folded when the insect is alarmed or at rest so that the 
knees project outwards ; in this state it is very hard to get the legs out, 
even when the insect is somewhat relaxed, and the species is therefore 
one of the most difficult weevils to set properly, 
The larva bores galleries, which are slightly winding, in the stems of 
osiers, and sometimes does considerable damage; the perfect insect 
appears to be to a certain extent crepuscular; I have found the males 
and. females together in numbers in an osier bed near Repton, 
Burton-on-Trent, at half-past four or five on a summer’s morning; 
but they appeared to be scarce in the middle of the day or in the after- 
noon in the same locality, 
C. lapathi, L. Black, dull, with the sides of the thorax, a more or 
less irregular and variegated fascia at base of elytra, and the apex of the 
same distinetly and more or less broadly, clothed with coarse imbricate 
yellowish-white scales; rostrum stout, slightly curved, punctured at 
base, almost glabrous and shining in front; head with black scales ; 
antenne reddish ; thorax searcely transverse, with the sides rounded and 
somewhat dilated in middle and narrowed before apex, central line 
carinate, punctuation consisting of close and coarse round shallow pune- 
tures, front portion with fascicles of raised black scales which look like 
tubercles ; scutellum black ; elytra with the fascia at base varied with 
black or fuscous, punctures of strize very large, round or ovate, compara- 
tively shallow, interstices closely punctured, third, fifth and seventh 
furnished with fascicles of raised black scales ; Suture with a very 
narrow raised margin ; underside black, sparingly punctured ; legs black, 
femora thickly scaled and furnished with two very small teeth. L, 
8-9 mm. 
Male with the first ventral segment of the abdomen longitudinally 
excavated ; Thomson and others mention the femora as furnished with 
two teeth in the male only, but they appear to be more or less distin- 
guishable in both sexes. 
On willows; also, according to Bedel, on poplars and alders ; local, but widely dis- 
tributed and not uncommon in some districts ; Putney, Earls Court, Chatham, &c. ; 
Dagenham, Essex; Ramsgate ; Norfolk; Dover; Hastings district ; Bewdley ; 
Repton, Burton-on-Trent ; Southport ; Blackpool; York; Northumberland and 
Durham district ; Scotland, rare, in old sallows, Solway and Forth districts,

More than a hundred species belong to this genus, which are very 
widely distributed ; thirty-four are found in Europe and the remainder 
have been described from the Canaries, Madeira, North, Central and 
South America, Cuba, the Australian region, &c. ; in fact they will pro- 
bably be found to extend over the whole world ; they are small, incon- 
spicuous, rough-looking insects, which are found in dead branches of trees, 
by beating faggots, &e.; when alarmed they fold up their legs and
