 Bristol.

Rhy. Myriophylli. Gyllenhal. iii. 152. — Cu. Hydrolapathi. Mus. Marsham.— 

 Pa. Hydrolapathi. Steph. Catal. 159. No. 1614. 



Somewhat depressed, black, opaque, densely clothed with whitish scales beneath, 

 and sprinkled with dirty-white ones above : head somewhat piceous, finely 

 punctured : thorax unequal, luith two small remote denticulations on the 

 anterior margins, and a short acuminated tubercle on each lateral one, which 

 latter are densely clothed with whitish scales, the disc with a deep central 

 channel, and an oblique impression on each side : elytra obsoletely striated, 

 with the inflexed lateral edge covered luith whitish scales, and a small whitish 

 spot towards the base of the suture : legs slender, rv£o-testaceous, with the 

 joints and tarsi dusky-black. 



Taken on the water-dock, and other aquatic plants, in the neigh- 

 bourhood of London. " Newcastle-upon-Tyne." — G. Walks, Esq. 



Genus CCXCIII. — Anoplus, Schonherr. 



Antennce geniculated, 12-jointed, short, rather stout, the basal joint reaching to 

 the eyes, the second obovate, thick ; the third to the eighth short, subperfoliate, 

 coarctate, club ovate. Bostrum thick, slightly bent, not inserted in a pectoral 

 groove: eyes rounded, remote: Moraa; attenuated anteriorly, slightly coarctate, 

 the base bisinuated : scutellum small : elytra convex, ovate, covering the 

 pygidium: legs stout, anterior approximating ; _/emora subclavate, unarmed: 

 tarsi stout, ciliated, the terminal one broad, without a claw. 



The want of a claw to the terminal joint of the tarsi of this 

 genus at once points out its prominent distinctions from its allies : 

 the rostrum is not inserted in a pectoral cavity — is short, stout, and 

 but little bent : the tarsi are broad, especially the terminal joint, 

 which is emarginate at the tip, and deeply ciliated: — with such 

 characters it is obviously improper to associate the present genus 

 with Ceutorhynchus, as has been recently done, notwithstanding 

 the excellent arrangement of Schonherr.
