plainly pubescent, striate and rugose at base ; thorax with the sides

D. salicinus, Gyll. Elongate, narrow, pitchy black, or more or less 

 ferruginous, variegated, and clothed with whitish pubescence ; head 

 small, black, closely punctured ; rostrum longer than the head and 

 thorax, nigose-striate, black, with the apex rufous; antennae ferruginous, 

 with the club black ; thorax evidently longer than broad, slightly 

 diluted and evenly rounded at the sides, black, with the anterior and 

 posterior margins rufous, thickly punctured and sparingly pubescent. 

 Elytra long and narrow, scarcely broader at base than thorax, with 

 the shoulders somewhat elevated and the sides straight, punctured stria} 

 distinct, interstices narrow and rugose, pubescence coarse; breast black, 

 thickly pubescent ; legs pitchy, or lighter or darker red ; colour very 

 variable, presenting all shades from pitchy-brown almost black, to red- 

 dish-testaceous ; the head, however, is always black. L. 3-3^ mm. 



Male with the rostrum shorter and more pubescent than in the female, 

 and with the teeth of the femora stronger. 



On willows ; rare or rather extremely local; Horeton, Horning, Norfolk (Power) ; 

 Horning Marshes, in July or the beginning of August (Curtis) ; Wicken Fen, Cam- 

 bridge, in profusion, April 9th, 18G3 (Power) ; Mr. Blatch has also taken it in the 

 latter locality. Scotland, Solway district, common in Dumfriesshire (Sharp). 



This and the two following species may be known from the two pre- 

 ceding by their black head, and from D. hirtipennu (ttatiattu), which 

 they resemble in size, by the absence of black raised setae on the elytra ; 

 D. salicinus is one of the most distinct of all the species and one of the 

 most easily recognized, by reason of its elongate form, narrow elytra, 

 which are scarcely broader than thorax, and especially by the fact that 

 the thorax is evidently longer than broad, whereas it is plainly trans- 

 verse or subtransverse in all our other species. 



D. salicis, Wa!t. Oblong-ovate, rufo-ferruginous, with the head, 

 rostrum, and breast black ; sparingly clothed with ashy pubescence, and 

 maculated on the elytra ; head small, subglobose, thickly punctured, 

 with the forehead channelled, black ; rostrum rather thick, as long as 

 the head and thorax, rugosely striate, pubescent, black, \\ ith the apex 

 testaceous ; antennae reddish, with the club black ; thorax slightly 

 transverse, or almost as long as broad, with the sides dilated and
