B. venosus, Grav. (glandium, Brit. Cat.,nec Marsh). Black, upper 
and under surface entirely covered with greyish-yellow or light brownish 
yellow scales, variegated with bands and markings of brownish or 
yellowish brown seales, antennz and legs ferruginous, the latter thickly 
scaled ; rostrum lighter or darker red, usually darker at base and apex, 
strigose, punctured and pubescent at base, where it is thickened ; last 
joints of the funiculus elongate ; thorax with three longitudinal lighter 
bands, with the sides rather strongly rounded and considerably narrowed 
in front but not constricted, the long scales meeting in a sort of longitu- 
dinal line on the raised central line ; scutellum narrow, longer than 
broad ; elytra broader than thorax, with well marked shoulders, gradually 
narrowed to apex, which is much narrower than base, with the long 
scales set more thickly and raised on the hinder half, striz fine, inter-

is rather plentiful at times; Swansea; not common in the Midland districts, Bretby 
Wood, Repton and Sherwood Forest ; I know of no record from further north than 
the last-named locality. 
B. nucum, L. Of about the same size as, or rather larger than, the 
preceding, and closely allied to it, but easily distinguished by the 
broader and less convex form, broader scutellum, and the evidently 
longer rostrum of the female, which is longer than the whole body, as 
well as by the plainly shorter and stouter, and somewhat pyriform last 
joints of the funiculus of the antennz, which are entirely clothed with 
blackish hairs; the general colour and arrangement of the scales is much
