than the first of the club ; — the elytra are more abbreviated than in 

 Dendrophilus, and the antennse are differently constructed : — the 

 species are found beneath the bark of dead and decaying trees, and 

 appear rare in Britain. 



Sp. 1. depressa. Atra, nitida, thorace lateribus subtiliter punctato, elytris striis 



tribus integris, suturali nulld. (Long. corp. 1^ lin.) 

 Hi. depressus. Fabricius. — PL depressa. Steph. Catal. 103. No. 1083. 



Deep black, very glossy : forehead excavated : thorax very broad, depressed, 

 with the lateral margin finely punctate : elytra each with three entire striae on 

 the outer edge, and a fourth abbreviated one within at the apex, and sometimes 

 with the rudiments of a fifth between the latter and the suture: legs obscure 

 pitchy-black, the anterior tibiae dilated and quadridentate : antennae fer- 

 ruginous. 



Differs from the following in being more depressed, broader, and by having only 

 four striae on the elytra. 



Rare ; found beneath the bark of the oak and beech near London, 

 and in Norfolk. " I have a memorandum that it has been taken 

 under bark (near Swansea)." — L. W. Dillwyn, Esq. 



J Sp. 2. oblonga. Linearis, subdepressa, atra, nitida, elytris sex striatis, tribus 



exterioribus integris. (Long. corp. 1^ lin.) 

 Hi. oblongus. Fabricius. — PL oblonga. Steph. Catal. 103. No. 1084. 



Linear-elongate, somewhat depressed, shining black : forehead excavated : thorax 

 subquadrate, above a little convex, the disc smooth, the lateral margins thickly 

 and finely punctured : elytra linear-elongate, with the back depressed ; each 

 with six striae, of which the three inner ones are more or less abbreviated : 

 legs pitchy-black; with theanterior tibiae quadridentate, the posterior bidentate, 

 with the apex bicuspid : antennae ferruginous. 



Known by the six striae on the elytra, exclusively of its dissimilarity in form, &c. 



Very rare : I have hitherto seen but the specimens which are in. 

 the British Museum, and which were taken " near Norwich, be- 

 neath the bark of trees, by the late J. Hooker, Esq. 1 ' — Dr. Leach. 



Subsectio II.— LAMELLICORNES, Latreille, 



Contains such herbivorous Coleoptera as have the antenna clavate, with the club 

 composed of three or more lamellae, or pectinations, the legs fossorial, with the 

 tibiae externally dentate and spinulose, and the tarsi mostly pentamerous.
