314 ^Ir. J. Walton on the British species of 



above, closely puuctulatecl on the disk, rugulose-punctate towards 

 the sides, and with a distinct, smooth, dorsal carina. Elytra 

 long-ovate, the shoulders a little elevated, the sides dilated and 

 rounded, punctate-striate, the punctures close and rather large. 

 Legs shortish, entirely testaceous or rufous ; femora armed with 

 a small tooth. Length 1| line. 



Very similar and closely allied to D. maculatus and D. tceniatus, 

 principally differing in having the elytra shorter in proportion to 

 the length, with the sides dilated and rounded, and in being a 

 much smaller insect. 



Some years ago I took a single specimen ofif willows in York- 

 shire; since which several specimens have been taken from the 

 gray sallow [Salix cinefea) on Wimbledon Common, in June, by 

 Mr. S. Stevens. 



8. D. Salicinus, Gyll., Schijnh. 



Elongate, narrow, piceous-black, variegated, and sparingly 

 clothed with white pubescence. Head small, rounded, black, 

 closely punctulated ; eyes rotundate, black ; rostrum longer than 

 the head and thorax, rugose-striate, black, with the apex rufous. 

 Antennae feiTuginous, the clava black. Thorax long, subde- 

 pressed on the disk, slightly dilated and equally rounded at the 

 sides, black, with the anterior and posterior margins rufous, 

 thickly punctulated and sparingly pubescent. Elytra long, nar- 

 row, not much broader than the thorax, the shoulders somewhat 

 elevated, the sides straight, punctate-striate, nigro-piceous or 

 fusco-ferruginous ; maculated with white pubescence ; the breast 

 black, densely pubescent. Legs entirely testaceous or obscure 

 ferruginous. Length l|-lf line. 



Extremely variable in colour ; the rostrum, thorax and elytra 

 vary from piceous to testaceous, are either entirely of one colour 

 or indefinitely variegated with different shades of both ; it may 

 however be ilistiuguished by its narrow elongate form, its oblong 

 thorax, and its small size. 



I possess six Swedish specimens from Schonherr. 



Found on willows in Scotland by the Rev. Wm. Little. " On 

 willows, Horning Marshes, Norfolk, in July or the beginning of 

 August," Mr. Curtis. 



9. D. majalis, Payk., Gyll., Steph., Schonh. 



There are two foreign specimens of this insect in Mr. Kirby's 

 collection from Gyllenhal, and one in mine from Schonherr : in 

 Sweden it inhabits the flowers of Salix cineren, in May and June. 



The smallest species of the genus (length I3-II line), and has 

 not hitherto to my knowledge been found in tlie South of England; 

 I have received many specimens from the Rev. Wm. Little, taken 

 by him in Scotland. " Near Carlisle," T. C. Heysham, Esq.
