276 RHYNCHOPHORA. [ Dorytomus. 
gated as in many of the allied species; head thickly punctured, rostrum 
rather stout and comparatively short, very dull, striated and rugose, and 
almost straight to the insertion of the antenne ; antenne red or pitchy 
red ; thorax transverse, closely and rather strongly punctured, slightly 
narrowed at base; elytra with strongly punetured striz, interstices very 
narrow, with the shoulders and a small pomt before apex with white 
pubescence; these small spots are however not, or scarcely, distinct 
from the general variegation; legs red or pitchy red, femora toothed. 
L. 3-4 mm. 
Male with the teeth of the femora stronger and the antenne inserted a 
little behind apex of rostrum. 
On willows ; very local and, as a rule, rare; Birdbrook, Essex, in numbers (ninety 
specimens were taken by Dr. Power on one oceasion, Feb. 16th to 18th, 1868, and £ 
remember his telling me that in collecting them from bark in a marshy place he 
caught a serious illness, which laid him up for a long time); London district 
(Stephens); Northampton (Greville and Hamlet Clark); banks of the Bollin, 
Cheshire, and banks of the Mersey (Chappell) ; Strettord district, Manchester (Res- 
ton) ; Northumberland and Durham district, Castle Eden Dene (Bold) ; not recorded 
from Scotland, 
The species may be known from its nearest allies by the rugosely sculp- 
tured rostrum, and especially by the black set on the elytra, as well as 
by its smaller size. 
D. validirostris, Gyll. Oblong-ovate, black or ferruginous, variegated 
with greyish spotted pubescence; head finely punctured, rostrum very 
short, thick, nearly straight, closely and finely punctured, and sparingly 
pubescent ; antennze ferruginous, with the club fuscous ; thorax trans- 
verse, abruptly narrowed in front, with the sides dilated and rounded, 
closely punctured, thickly pubescent at sides; elytra with the shoulders 
elevated, the sides straight, a little convex above, finely striated, the 
strie being closely punctured, in mature specimens pitchy black, but 
often lighter, with the suture and a band towards the side of the elytra 
pale red, variegated on disc and more or less at sides with unequal 
fuscous blotches, interspersed with whitish spots ; the outer margins, 
from the shoulders towards the apex, are, in fresh and mature specimens, 
often broadly edged with whitish ; legs short, robust, ferruginous, some- 
times pale rufous; femora clavate, armed with a strong tooth. L. 4-44 
mm, 
Ou Populus nigra; very local but not uncommon where it occurs; first taken by 
Mr. S. Stevens near Hammersmith bridge, and found by him in numbers on the Barnes 
side, and also taken in profusion by Mr. Walton in the same locality, after a high 
wind, on the lower branches of poplars, and on the grass and shrubs beneath; Dr. 
Power once took thirty in Mr. Brewer’s garden (I believe, near London) ; Needwood, 
Staffordshire (Gorham). 
D. maculatus, Marsh (/umosus, Steph. Jl].; teniatus, F., nec 
Brit. Cat.). Black or pitehy black, or, as is usually the case in most of 
the darker species, more or less ferruginous in examples that are not quite
