278 RHYNCHOPHORA. [ Dorytomus. 
buted, but confused with the ordinary type form; Seotland, common, Solway, 
Forth, Tay, Dee and probably other districts. 
D. affinis, Payk. Black, clothed with thick ashy pubescence, dull, 
antenne 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 
punctured, 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. maeulatus 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. 43-5 mm. 
Male with the antenne inserted a little behind the apex of the 
rostrum, 
On aspens ; very rare; introduced by Walton as British on a single specimen taker 
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- 
dant (Dale), but this may bein error, as the species is very closely allied to others ; 
it hasa 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. melanophthalmus, Payk. Oblong, rufo-testaceous, more or 
less pitchy beneath, clothed with pale ashy pubescence, which is 
slightly variegated on the elytra; head punctured, pilose ; antenne 
slender, rufo-testaceous ; rostrum longer than the head and thorax to- 
gether, regularly curved for its whole length, stout, striated and pune- 
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 stria, 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 antenne inserted 
nearer the front of the rostrum, LL, 3-4 mm. 
V. agnathus, Boh. (dorsalis, Thoms.?). 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 Axwell 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 antenne and then slightly curved ; colour red or 
yellowish-red ; breast brown or blackish ; rostrum with the apex fuscous,
