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, rugose-striate, black, with the apex rufous; antenne ferruginons,

the shoulders somewhat elevated and the sides straight, punctured striz 
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-

This and the two following species may be known from the two pre- 
ceding by their black head, and from D. hirtipennis (teniatus), which 
they resemble in size, by the absence of black raised set 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, Walt. 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, with the apex

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