Balaninus.\ RHYNCHOFHORA. 385 



the same as in B. veno&is, 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 hody, the antennae 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 antenna; 

 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. nee Fourc. (?) ; glandium, 

 Marsh, sec Bedel ; nucum, Germ, nee 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 antennse 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 appear 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. -i|-5 mni. 



Chiefly on species of oak (Quereus rdbur, ilex, Ac.), but occasionally on hazel ; 

 not common ; Shirley, Croydon, Coombe Wood, Horsell, Cowfold, Claygate, Darentb, 

 Dulwich, Birch Wood, Westerham, Shipley, near Horsham, Chatham, Sheerness, &o. ; 

 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. betulae, Steph. (Herbsti, Gemm., cerasomm, Herbst.). A small 

 and pretty lighter or darker ferruginous, species, variegated with pale 

 yellowish-grey and reddish scales ; antennae, 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 

 striae, interstices rugosely punctured anterior and intermediate femora 

 simple, posterior femora with a small but distinct and sharp tooth. 

 L. 3-4 mm.
