Contributions to a Synopsis of British Coleoptera. 

 By G. R. Crotch, Esq. 



The following paper is an extract from a Monograph of 

 Balaninns and Anthononius in the ' Annales cle la Sociele 

 Entomologique de France,' 1868, by M. Desbrochers de 

 Loges. My series was submitted to him at the time, and 

 hence may be considered to represent his views with cor- 

 rectness. 



Bx^LANINUS. 



Group 1. — Large species, clothed with jjaler scales; antennae 

 with the joints slender, elongate; club acuminate. 



A. Posterior femora with a strong tooth. 



1. B. Glandium, Marsh (venosus, Germ.) Black, densely 

 clothed vvitli ferruginous scales, the elytra with darker spots ; 

 legs thick and strong; elytra separately rounded at the apex ; 

 scutellum narrow : length 3 — i^ lines. Common on oaks, &c. 



2. B. tesselatus, Fourc. (turbatus, Gyll.) Black, densely 

 clothed with ferruginous scales ; rostrum very elongate in the 

 female and much curved; antennae pubescent, with the joints 

 of the funiculus elongate : length 3 — 3^ lines. Rare. 



3. B. Nucuni, L. Very like the preceding, but with the 

 rostrum less curved and the antennae very pilose, the latter 

 joints of the funiculus being subnodose : length 3 — 5 lines. 

 Common everywhere. 



(To this group belongs the hitherto unidentified B. pel- 

 litus, Sv/ili., very like B. Glandium, but the femora have a 

 subtriangular tooth, not unciform as in the latter, and the 

 rostrum is hardly incrassate at the base.) 



B. Posterior femora with a minute tooth. 



4. B. villosus, Fdb. Black, beneath cinereous ; elytra with 

 a posterior fascia, and the scutellum cinereous : length 2^ — 4 

 lines. Common.
