upper surface black, variegated with grey or white 



scales B. VILLOSUS, F. 



II. Club of antennae oval, with the first joint as long as 

 the following taken together tarsal claws toothed at 

 base only ; upper surface black, without scales, 

 clothed with fine greyish pubescence ; size very 



small (Balanobius, Jekel). 

 i. Teeth of femora comparatively large, distinct ; 



metasternum and metasternal episterna clothed 



with white scales ; funiculus of antennae black or 



pitchy ; rostrum black in both sexes ; interstices of 



elytra broader B. SALICIVOEDS, Payk. 



(brassicce, F.?) 

 ii. Teeth of femora small, often more or less obsolete, 



at all events on anterior pair ; metasternum simply 



pubescent, metasternal episterna clothed with white 



scales; funiculus of antennae red ; rostrum red in 



front in male ; interstices of elytra narrower . . B. PYBBHOCERAS, Marsli. 



B. venosus, Grav. (glandium, Brit. Cat., wee 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 scales, antennae 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, striae fine, inter- 

 stices broad ; all the femora armed with a strong tooth. L. 6 mm. 



Male with the antennae inserted in front of middle of rostrum which 

 is rather shorter. 



Female with the antennas inserted at about middle of rostrum which 

 is rather longer. 



On oaks in woods and hedges ; local ; rather common and generally distributed 

 in the London district and the South of England as far as the New Forest, where it 

 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. nueum, 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 antennge, which are entirely clothed with 

 blackish hairs; the general colour and arrangement of the scales is much
