CURCULIONIDiE. — ORCHESTES. 59 



punctate-Stria te, immaculate : legs black ; antennae piceous at the base, black 

 towards the apex. 



In June, 1827, 1 discovered a single specimen near Ripley, which 

 is the only indigenous example I have hitherto seen. 



Genus CCXCVII. — Orchestes, Illiger. 



Antennw geniculated, 11-jointed, rather short and slender, funiculus 6-jointed, 

 its first joint large, obconic, second and third oblong, obconic, the remainder 

 subequal, short, truncate at the apex; club thick, oblong-ovate. Rostrum 

 inflexed, elongate, rather stout, and rounded, bent, free : eyes large, round, 

 prominent, approximating : thorax small, subconic, bisinuated or subtruncate 

 behind: elytra oblong-ovate, broader than the thorax, the apex obtusely 

 rounded : pygidium sometimes exposed : legs stout, anterior approximating, 

 posterior longest: Jemora clavate, posterior generally very much incrassated, 

 formed for leaping, sometimes denticulated. 



The saltatorial hinder legs of the insects of this genus, com- 

 bined with their approximating eyes, inflexed rostrum, and 6-jointed 

 funiculus of the antennae, at once point out their distinctions from 

 the other genera of this extensive family : the larvse are subcuta- 

 neous, and the imago sometimes exists throughout the winter. 



A. With the hinder femora denticulated. 



Sp. 1. Quercus. Rufo-testaceus, pubescens, oculis pectoreque nigris, elytris plagd 

 anticd triangulari cinereo-pubescente, jemoribus posticis serrato-dentatis, 

 (Long. Corp. 1^ — 2^ lin.) 



Cu. Quercus. Linne. — Cu. rufus. Donovan, xi. pi. 389. f. 3. — Or. Quercus. 

 Steph. Catal. 160. No. 1634,. 



Rufo-testaceous, pubescent : eyes pitchy-Zl/ac^• ; thorax bisinuate at the base, 

 with an obsolete dorsal channel: scutellum whitish: elytra punctate-striated, 

 with a large triangular common blotch extending from the shoulders to beyond 

 the middle of the suture densely clothed with a pale pubescence, the rest of 

 the surface being less densely clothed, and the pile of a ferruginous hue : 

 breast black; Aa^aZ joints of the abdomen dusky, or black; apex ferruginous; 

 four anterior femora, each with a minute spine in the middle, the posterior 

 with a double series of six or seven spines on each. 

 Not uncommon on oaks during the summer in England. 



Sp. 2. scutellaris. Oblongus, rufo-ferrugineus, oculis, rostri apice, pectore abdo- 

 mineque nigris, scutello albido-piloso, femoribus posticis unidentatis. (Long, 

 cor p. 1^ lin.) 



Rh. scutellaris. Fabricius. —Cu. rufus. Donovan, vii. pi. 249./. 1.— Or. scutel- 

 laris. Steph. Catal. 16\. No. 1635.
