1<J8 RHYNCliOPHORA. [LiophloetlS. 



species is a large insect, with the scrobes curved and deflexed and the 

 apex of the tibiae with the outer margin reflexed and forming a cavity 

 for the insertion of the tarsi. 



It. nubilus, F. (tessellatus, BonsdJ. 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 strife 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, loculj a large number of specimens were taken at Beuton 

 feeding on the ivy ; Scotland, scarce, Solway, Dee and probably other districts ; 

 Ireland, Belfast, Gahvay, Waterford, Dublin, and most likely general. According to 

 Bedel the females haTO a transverse yellowish, almost membranous band, at the 

 posterior margin of the second, third, and fourth segments of the abdomen j this baud, 

 in the males, is rudimentary or absent. 



OTETALLTTHS, Gerrnar. 



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 f uniculus of the antennae 

 globose and subtransverse ; the antennae 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. 



X. marg-inatus, 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 ; antennae ferruginous, comparatively 

 short and stout, with the last joints of the f uniculus very short ; thorax 

 rather longer than broad, with the sides rounded, very closely sculp- 

 tured ; elytra with rather deep punctured stria?, and with lighter and 

 darker scales arranged in more or less distinct lines, the suture and sides 

 being lighter than disc, although sometimes obscurely so ; legs reddish 

 testaceous, femora clavate and all plainly, as a rule, 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 Woottou (common) ; the species has recently been found in France bu the 

 birch.
