One foreign specimen in Mr. Kirby's collection, and two in 

 mine, the latter from Schonherr, identify, and conlirm the name 

 of this insect. 



Generally distributed. Common on willows {Salix Caprece) 

 from June to October. 



11. D. agnathus, Dahl., Schonh. 



— majalis, Steph. sec. ej. Mus. 



Oblong, rufo-testaceous, nigro-piceous beneath ; clothed with 

 pale cinereous pubescence. Head rotundate, convex, thickly 

 punctulated, rufo-piceous, densely pilose ; eyes moderately pro- 

 minent and black; rostrum longer than the head and thorax, 

 stout, curved, cylindrical, striated and punctulated, rufo-testa- 

 ceous or piceous,and pubescent. Antennae slender, rufo-testaceous. 

 Thorax rather broader than long, narrowed anteriorly, depressed 

 within the apex, much dilated and rounded at the sides, a little 

 convex above, thickly punctulated, rufo-ferruginous. Elytra ob- 

 long, scarcely twice as broad as the base of the thorax, the 

 shoulders rounded, slightly elevated, the sides inflexed, not di- 

 lated, three times the length of the thorax, moderately convex 

 above, finely punctate-striate, the interstices rather convex, very 

 finely coriaceous, rufo-ferruginous ; each elytron with a broad 

 piceous stripe down the middle, abbreviated posteriorly ; densely 

 clothed with short pale pubescence. Legs moderate, rufo-testa- 

 ceous, pubescent ; femora clavate, each armed with a large tooth. 

 The male. Length 2-2^ lines. 



The female has the rostrum longer, shining, obsoletely stri- 

 ated ; the elytra concolorous ; the femora acutely denticulated. 



Closely allied to D, pectoralis, from which it differs in being 

 longer, proportiouably narrower and less convex; the rostrum 

 longer and more curved. 



I possess a foreign male specimen from Schonherr. 



I first received specimens of this very distinct new British in- 

 sect from the Rev. Wm. Little, who found them in Scotland; and 

 subsequently from Mr. S. Stevens, taken by him ofi^ willows near 

 Weybridge, in company with D, pectoralis. From the paucity of 

 specimens in cabinets it appears to be local and rax*e.

— arcuatus (var.), Steph. sec. ej. Man.
