276 RHYNCHOPHOHA.. [Dorytomug. 



gated as in many of (he allied species ; head thickly punctured, rostrum 

 rather stout and comparatively short, very dull, striated and rugose, and 

 almost straight to the insertion of the antennae ; antenna? red or pitchy 

 red ; thorax transverse, closely and rather strongly punctured, slightly 

 narrowed at base ; elytra with strongly punctured striae, interstices very 

 narrow, with the shoulders and a small point before apex with white 

 pubescence ; these small spots are however not, or scarcely, distinr-t 

 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 antennae inserted a 

 little behind apex of rostrum. 



On willows ; very local an-', as a rule, rare; BirJb-ook, Essex, in numbers (ninety 

 specimens were taken by Dr. Power on one occasion, Feb. 10th to 18th, 186S, and [ 

 remember his telling 1 me that in collecting them from bark in a marshy place he 

 caught a serious illness, which laid him np for a long time) ; London district 

 (Stephens}; Northampton (Greville and JIamlet Clark); banks of the Bollin, 

 Cheshire, and banks of the Mersey (Chappell) ; Strettbrd district, Manchester (Rej- 

 t'lii) ; 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 seta? 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 h'nely punctured, and sparingly 

 pubescent ; antenna? 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 

 stria? 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. 4-4| 

 mm. 



On Populus nigra ; very local but not uncommon whrre it occurs; first taken by 

 Mr. S. Stevons 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 hijjh 

 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 (fumosus, Steph. 111.; tceniatus, F., nee 

 Brit. Cat.). Black or pitchy black, or, as is usually the case in most of 

 the darker species, more or less ferruginous in examples that are not quite
