the male, and at about the middle in the female; thorax compara- 
tively long, conical, obsoletely channelled, with the sides not rounded 
or dilated ; elytra with strong, crenulately punctured striz, interstices 
convex, somewhat rugose transversely; legs black, posterior femora 
comparatively slightly thickened ; the rostrum is shining and punctured 
and has an abbreviated channel in the middle. L, 25-3 mm. 
On sallows, willows, alders, &c.; locally common; London district, common ; 
Norfolk; Hastings ; Portsmouth distriet ; New Forest; Glanvilles Wootton ; Nettle- 
comb, Somerset; Midland districts, general ; Langworth Wood, Lincoln; Stretford, 
near Manchester; Liverpool district, local; Northumberland and Darham district 5 
Scotland, scarce, Solway, Tweed, Forth and Clyde districts. Ireland, near Dublin. 
O. decoratus (Germ. zee Steph.*). Suboval, slightly convex, black, 
sparingly pubescent, rather dull, with the antenne and tarsi testaceous ; 
rostrum obsoletely punctured ; thorax strongly transverse ; scutellum 
thickly clothed with white scales ; elytra with two rather obsolete 
fascize formed of small white lines, with punctured striz, interstices 
eranulately punctured ; the antennz are inserted a little behind the 
middle of the rostrum ; Thomson compares the species with O. rusci 
and says that it is distinguished by having the rostrum obsoletely 
punctured, the antenne eleven-jointed, the club longer, the scutellum 
(which in O. rusez is dark but has a whitish longitudinal patch before it) 
clothed with white scales, and the interstices dull and granulately 
punctured. L. 25 mm. 
On the leaves of willows; the larva has been found on Salix fragilis ; Scotland, 
very rare, on sallows, Solway district (Sharp, Scot. Nat., Oct. 1879, p. 191); mreh 
confusion has arisen with regard to this species, through the errcr of Stephens ; the 
species was omitted from our lists, but has now been reinstated by Dr. Sharp, who 
: lone has taken the true iaseet in Britain ; he has kindly lent me a specin en and 
suys that it is no doubt still to be found about Cairn Water in Dumfriesshire ; it 
a} pears to be not uncommon in Central and Southern Europe. 
O. salicis, L. (bifasciatus, F. nec Steph. ; capree, F.). Ovate, deep 
black ; head thickly punctured, rostrum with fine punctures ; antennz 
testaceous with the club fuscous, the scape being inserted at about 
middle of rostram ; thorax transverse, closely punctured, with yellowish- 
white seale-like hairs in middle, and whitish hairs at sides near base, 
which are often rubbed off; scutellum white; elytra with broad and 
ileep punctured striz, interstices somewhat convex, transversely rugose, 
iather shining, with two bands of white scales, the hinder one narrow 
and almost regular, tne one in front, dentate and much widened in 
middle and joining the longitudinal patch before scutellum ; this patch 
aud the space on each side of it is more or less distinctly 1eddish or 
reddish-yellow ; the markings are very distinct; legs entirely black, a 
character that will easly separate it from O. rusct. LL. 25—-2$ mm. 
On willows and sallows ; the larva has been observed on S. fragzl/s; not uncommon 
und very widely distributed throughout England and Wales; Scotland, common, Sol- 
way, Tweed, Forth, Dee and probably other districts. Ireland near Dublin and Belfast 
* The O. decoratus of Stephens, as well as his O. affinis, are only O. rusci,
