198 RHYNCHOPHORA. [ Liophleus. 
species is a large insect, with the scrobes curved and deflexed and the 
apex of the tibie with the outer margin reflexed and forming a cavity 
for the insertion of the tarsi. 
ZL. nubilus, F. (fessel/atus, Bonsd.). Black, dull, densely clothed 
with ashy-brown scales, which occasionally, in freshly emerged speci- 
mens, are coppery; these scales are thicker at the sides of the thorax, 
and the elytra have the alternate interstices tessellated with small fuscous 
spots ; head with a longitudinal impression between eyes; thorax with 
the sides slightly rounded, very closely sculptured, with a more or less 
obsolete raised central line ; elytra large and ample, much broader than 
thorax, with punctured striz and broad flat interstices; legs black, 
pubescent ; the colour of the scales is variable ; in the male, which is 
smaller, they are lighter and the dark tessellated patches are more evident. 
L. 8-11 mm. 
On hedges, young trees, nettles, &c., also by beating ivy, which seems to be the 
especial food plant of the insect ; generally distributed and common throughout the 
greater part of England and Wales; not so common further north ; Northumberland 
and Durham district, local; a large number of specimens were taken at Benton 
feeding on the ivy; Scotland, scarce, Solway, Dee and probably other districts ; 
Ireland, Belfast, Galway, Waterford, Dublin, and most likely general. According to 
Bedel the females have a transverse yellowish, almost membranous band, at the 
posterior margin of the second, third, and fourth segments of the abdumen; this band, 
in the males, is rudimentary or absent. 
METALLITES, Germar. 
This genus, which contains about twenty species, mostly occurring in 
Europe, is united by M. Bedel with Polydrusus ; it differs, however, in 
having the third to the seventh joints of the funiculus of the antenne 
globose and subtransverse; the antenne themselves are shorter and 
stouter and the scutellum is strongly transverse and quadrangular ; the 
scrobes meet below rostrum; the legs are rather stout and the elytra 
somewhat acuminate ; one species only occurs in Britain. 
IM. marginatus, Steph. Oblong-ovate, dark, slightly rufous, 
clothed with hair-like cinereous scales, which are sometimes slightly 
coppery, and are thicker at suture and sides of elytra, and also on the 
forehead and at sides of thorax; antenne ferruginous, comparatively 
short and stout, with the last joints of the funiculus very short ; thorax 
rather longer than broad, with the sides rounded, very closely sculp- 
tured; elytra with rather deep punctured striw, and with lighter and 
darker scales arranged in more or less distinct lines, the suture and sides 
being lighter than dise, although sometimes obscurely so ; legs reddish 
testaceous, femora clavate and all plainly, as arule, though not strongly, 
dentate. L,. 3-4} mm. 
On broom and juniper; very local, but not uncommon where it occurs; Birch 
Wood, St. Mary Cray, Chatham, Bearsted, Black Park ; Henley; New Forest ; 
Glanvilles Wootton (common) ; the species has recently been found in France on the 
birch,
