278 RHYNCHOPHORA. [Eorytomus. 



bnted, but confused with the ordinary type form; Scotlund, common, Solway, 

 Forth, Tay, Dee and probably other districts. 



D. affinis, Payk. Black, clothed with thick ashy pubescence, dull, 

 antennae and legs obscurely ferruginous ; rostrum stout, almost straight, 

 scarcely as long as the head and thorax united, rugose and striate, 

 partially pubescent; thorax closely, finely, and somewhat obsoletely 

 piinctured, with the sides slightly rounded ; elytra variegated with 

 ashy pubescence and ferruginous spots, with a small white callosity be- 

 fore apex ; femora with pointed teeth ; the species may be distinguished 

 from typical D. maculatus by its larger size and much broader form, 

 and from the latter species and its varieties by having the rostrum 

 shorter, thicker, less curved, and evidently pubescent. L. 4| 5 mm. 



Male with the antennae inserted a little behind the apex of the 

 rostrum. 



On aspens; very rare ; introduced by Walton as British on a single specimen taken 

 by the Rev. H. Clark at the end of May, in an excursion to Gamlinghay, Cam- 

 bridgeshire ; London district and Swansea (Stephens); Glanvilles Wootton, abun- 

 dnnt (D;ile), but this may be in error, as the species is very closely allied to others ; 

 it has a very wide range from Siberia and Northern Europe to Algeria, and there is 

 no reason why it should not occur more commonly in Britain. 



D. melanophtlialmus, Payk. Oblong, rufo-testaceous, more or 

 less pitohy beneath, clothed with pale ashy pubescence, which is 

 slightly variegated on the elytra ; head punctured, pilose ; antenna? 

 slender, rufo-testaceous ; rostrum longer than the head and thorax to- 

 gether, regularly curved for its whole length, stout, striated and punc- 

 tured, slightly pubescent, red or brownish ; thorax rather broader than 

 long, depressed within apex, much dilated and rounded at sides, thickly 

 punctured; elytra oblong, much broader at shoulders than apex, with 

 distinct punctured striae, interstices closely punctured ; legs moderate, 

 femora clavate, armed with a sharp tooth, which is stronger in the 

 male than in the female; the former sex, also, has the antennae inserted 

 nearer the front of the rostrum. L. 3-4 mm. 



V. aynatlms, Boh. (dorsalis, Thorns. 1). In this variety the elytra 

 are dark at base, the colour extending for a greater or less distance 

 towards apex. L. 3-4 mm. 



On sallows (Salix caprea, cinerea, &c.) ; local, but not uncommon where it occurs ; 

 Darenth Wood, Weybridge, Woking, Horsell, Sydenham, Tilgate, Esher (in plenty 

 in the latter locality, Sept. 24th, 1870 (Power)); Hastings; Bewdley Forest; 

 Cromer ; Northumberland and Durham district, on willows, near Ax well Park; Scot- 

 land, local, Solway district. 



D. pectoralis, Gyll. (rufulus, Bedel). Closely allied to the pre- 

 ceding, from which it differs in being a little shorter and proportionately 

 broader and more convex, and also in having the rostrum almost straight 

 to the insertion of the antennae and then slightly curved ; colour red or 

 yellowish-red ; breast brown or blackish ; rostrum with the apex fuscous,
