13. D. validirostris , Schouh. 



— Waltoni, Schonh. Supp. vii. p. 171. 



Oblong-ovate, black, variegated with pale cinereous hairs. 

 Head subglobose, black, minutely punctured, the frons densely 

 pubescent ; eyes rather large, round, and moderately prominent ; 

 rostrum very short, thick, nearly straight, closely and finely 

 punctured, black, sparingly pubescent. Antennae ferruginous, 

 the clava black. Thorax transverse, abruptly narrowed in front, 

 dilated and rounded at the sides, closely punctulated, black, 

 densely clothed towards the sides with pale cinereous hairs. 

 Elytra with the shoulders elevated, the sides straight, a little 

 convex above, finely striated, the striae closely punctulated, pi- 

 ceous-black, the suture, and a vitta towards each side of each ely- 

 tron, pallid rufous; thickly pubescent, variegated on the back with 

 unequal fuscous blotches, interspersed with whitish spots ; the 

 outer margins, from the shoulders towards the apex, broadly 

 edged with white. Legs short, robust, ferruginous, sometimes 

 pallid rufous ; femora clavate, armed with a strong tooth. Length 

 2-2 i lines. 



The form and sculpture of the rostrum, with the beautiful va- 

 riation in the colour of the pubescence, distiiiguish this insect. 



I have six foreign specimens from Schonherr and Chevrolat. 



First discovered as a British insect by Mr. S. Stevens on the 

 south side of the Thames near Hammersmith Bridge, and subse- 

 quently under the bark of Populus nigra, in winter. I once 

 found it in profusion, after a high wind, on the lower branches 

 of the same kind of trees, and on the grass and shrubs beneath, 

 in the same locality. 



B. Femora simple.
