Balaninus.| RHYNCHOPHORA. 385 
the same as in B. venosus, except that the latter are rather more dense, 
and that the elytral markings are sometimes more obscure; as in the 
preceding species the hair-like scales are thickly set and upright on 
the apical half of suture of elytra; all the femora are armed with a 
strong tooth. L. 6—7 mm. 
Male with the rostrum shorter than the body, the antennz inserted in 
the middle of the rostrum, and the last ventral segment impressed in 
middle and tomentose on each side. 
Female with the rostrum a little longer than the body and the antennx 
inserted at some little distance behind the middle of rostrum. 
On hazel; in woods and hedges; local; generally distributed in the London 
district and the South of England, but less common further north; Swansea; 
Bretby Wood, Repton ; Sherwood Forest ; the only record from further north that I 
know of is Scotland, Forth district; the insect seems rather peculiar in its distribu- 
tion; M. Bedel records it as occurring generally in the basin of the Seine, but as rare 
in the environs of Paris. 
B. turbatus, Gyll. (tessellatus, auct. nec Foure. (2);  glandium, 
Marsh, sec Bedel ; nucum, Germ. nec L.). More ovate, smaller, and 
shorter than the preceding, with the rostrum longer in proportion ; it 
may easily be distinguished, moreover, by having the last joints of the 
funiculus of the antenne slender and elongate and only furnished with 
long hairs at apex ; the scales are rather more scanty and are as a rule 
darker, and the variegated markings are not very distinct; the legs also 
are more scantily clothed with scales and therefore appcar redder ; the 
suture of elytra has the raised scales towards apex much less marked ; 
in the female the rostrum is considerably longer than the body ; the 
whole insect, as a rule, presents a more ferruginous or ferruginous- 
brown appearance than is usual with either of the two preceding species. 
L. 45-5} mm. 
Chiefly on species of oak (Quercus robur, ilex, &c.), but occasionally on hazel ; 
not common; Shirley, Croydon, Coombe Wood, Horsell, Cowfold, Claygate, Darenth, 
Dulwich, Birch Wood, Westerham, Shipley, near Horsham, Chatham, Sheerness, &c. ; 
Hastings ; New Forest; Mr. W. Garneys has recorded it from Bretby Wood, near 
Repton, Burton-on-Trent, but I know of no other record from any locality north of 
the London district. 
B. betule, Steph. (Herbsti, Gemm., cerasorum, Herbst.). A small 
and pretty lighter or darker ferruginous species, variegated with pale 
yellowish-grey and reddish scales; antenne, rostrum, and legs red; 
underside evenly clothed with light scales ; thorax with fine and very 
close granulate punctuation, narrowed in front, with three lines of pale 
pubescence which are more or less distinct ; scutellum large; elytra 
very gradually and not strongly narrowed behind, with distinct punctured 
striz, interstices rugosely punctured ; anterior and intermediate femora 
simple, posterior femora with a small but distinct and sharp tooth.
