452 Mr. J. Walton on the genus Otiorhynchus. 



16. Otiorhynchus raucus J Fab., Gyll., Marsh., Steph., Schonh. 

 Rather uncommon and local. I never took but one specimen^ 



and that on a sandy bank under a hedge near Gravesend ; in 

 meadows near Hammersmith, and Hampstead, Mr. S. Stevens. 



17. O. {? Trachyphloms) fissirostris (Schonh. in litt.), Walt. 



Oblong-ovate, piceous-black, densely clothed with fuscous, 

 and variegated with cinereous recumbent scales, and rather spa- 

 ringly with short, erect, fuscous scales. Head black, somewhat 

 long, depressed, subcorneal, longitudinally ridged and striated 

 all round behind the eyes, the front very deeply furrowed to the 

 middle of the rostrum ; eyes small, round, and very prominent ; 

 rostrum distinctly shorter and narrower than the head, the apex 

 incrassated, angulated, triangularly emarginated above, deeply 

 excavated between the antennse, and the lateral margins greatly 

 elevated. Antennse rather long, testaceous; the scape robust, 

 gradually thickened towards the apex, slightly bent, nearly as 

 long as the flagellum, and squamulose ; the funiculus setose, the 

 two basal joints rather long, the second being thinner and a little 

 longer than the first, 3 to 7 obconic, rounded; the club ovate, 

 acute. Thorax black, rather longer than broad in the middle, 

 more narrowed in front than behind, obliquely truncated at the 

 base, impressed on each side anteriorly, moderately dilated at the 

 sides posteriorly, rather convex above, thickly rugose or rugose- 

 punctate, with a dorsal carina more or less abbreviated, and a 

 fovea on each side towards the middle sometimes indistinct; 

 densely clothed with fuscous scales, which are cinereous at the 

 sides. Scutellum scarcely perceptible. Elytra ample, oblong- 

 ovate, piceous-black, anteriorly broader than the base of the 

 thorax, the shoulders rounded, not elevated, moderately expanded 

 at the sides, the apex rounded, a little convex above, regularly 

 punctate-striate, the interstices narrow, alternately elevated; 

 densely clothed with round fuscous scales, which in recent speci- 

 mens are beautifully variegated with cinereous behind the middle 

 and towards the sides, and rather thickly clothed with short erect 

 fuscous scales. Legs with the femora and tibiae very stout, 

 rather short and piceous, the former clavate, edentate; densely 

 clothed with fuscous and cinereous scales, and the tarsi short, 

 slender and testaceous. Length 2J to 3 lines. Immature va- 

 rieties occur of a ferruginous colour. 



The specimen of this insect which I sent to Schonherr for his 

 opinion was returned with the name " Otiorhynchus (?) fissirostris, 

 n. sp. indescripta.^^ In general habit it resembles my foreign 

 specimens of Ot. septentrionis ; I have therefore placed it in this 

 genus with an indication of doubt, after the celebrated author of 

 the * Synonymia Insectorum ;' yet it assimilates very closely in
