202 RHYN OHOPHOR A , [ Orchetteg. 



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 striie, 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. 2|-3 mm. 



On sallows, willows, alders, &c. ; locally common; London district, common; 

 Norfolk; Hastings ; Portsmouth district ; New Forest; Glauvilles Wootton ; Nettle- 

 comb, Somerset; iVlidland districts, general ; Lungworth Wood, Lincoln; Stretford, 

 near Manchester ; Liverpool district, local ; Northumberland and Durham district ; 

 Scotland, scarce, Solway, Tweed, Forth and Clyde districts. Ireland, near Dublin. 



O. decoratus (Germ, nee Steph.*). Suboval, slightly convex, black, 

 sparingly pubescent, rather dull, with the antennae and tarsi testaceous ; 

 rostrum obsoletely punctured ; thorax strongly transverse ; scutellum 

 thickly clothed with white scales ; elytra with two rather obsolete 

 fasciae formed of small white lines, with punctured striae, interstices 

 granulately punctured ; the antennae 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 antennae eleven-jointed, the club longer, the scutellum 

 (which in O. rusci is dark but has a whitish longitudinal patch before it) 

 clothed with white scales, and the interstices dull and granulately 

 punctured. L. 2| 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) ; raven 

 confusion has arisen with regard to this species, through the error of Stephens ; the 

 species was omitted from our lists, but has now been reinstated by Dr. Sharp, who 

 alone has taken the true insect in Britain ; he has kindly lent me a specin en and 

 snys that it is no doubt still to be found about Cairn Water in Dumfriesshire ; it 

 appears to be not uncommon in Central and Southern Europe. 



O. salicis, L. (bifgedatvt, F. nee Steph. ; caprece, F.). Ovate, deep 

 black ; head thickly punctured, rostrum with fine punctures ; antennae 

 testaceous with the club fuscous, the scape being inserted at about 

 middle of rostrum ; thorax transverse, closely punctured, with yellowish- 

 white scale-like hairs in middle, and whitish hairs at sides near base, 

 which are often rubbed oft'; scutellum white; elytra with broad and 

 deep punctured striae, interstices somewhat convex, transversely rugose, 

 rather 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 

 and the space on each side of it is more or less distinctly reddish or 

 reddish-yellow; the markings are very distinct; legs entirely black, a 

 character that will easily separate it from O. rusci. L. 2|--2f mm. 



On willows and sallows ; the larva has been observed on S. fragilis ; not uncommon 

 and very widely distributed throughout England and Wales; Scotland, common, Sol- 

 way, Tweed, Forth, Dee and probably other districts. Ireland near Dublin and Belfast 



* The 0. deeoraius of Stephens, as well as his 0. affinis, are only 0. rusci.
