274 MANDIBULATA. COLEOPTERA 



prominent, the disc slightly convex : elytra very long : body sublinear, pubes- 

 cent: legs rather slender: tarsi with the three basal joints, with a spongeous 

 process beneath, obscurely bilobed ; the fourth joint minute, simple; terminal 

 joint and claws slender, the latter simple. 



There is considerable diversity between the insects comprised in 

 this genus; but without a more rigid investigation of them than I 

 have the opportunity of devoting to their examination, I must con- 

 tent myself with pointing out some of the more important external 

 distinctions ; which characters have chiefly guided me in the distri- 

 bution of the Elateridse : — the first section of this genus may be 

 distinguished by having the antenna? rather long, the second joint 

 manifestly abbreviated, and more or less subglobose ; and the third 

 elongate, subclavate ; while in the second section the antennae have 

 the second joint somewhat lengthened, and in some instances 

 scarcely shorter than the third : the body in both sections is some- 

 what linear, subconvex ; and the tarsi have the fourth joint ex- 

 tremely minute, and the three basal ones considerably dilated, and 

 in some species obscurely bilobed. 



A. With the second joint of the antennae more or less subglobose. 



Sp. 1. pubescens. Rufo-testaceus, cinereo-tomentosus : oculis nigris. (Long. 



corp. 8 — 9 lin.) 

 El. pubescens. Marsham MSS.—N. G. pubescens. Steph. Catal. 126. No. 



1279. 



Body entirely of a pale rufo-testaceous hue, and slightly clothed with a cinereous 

 pubescence : forehead deeply impressed between the antennae, which latter 

 are rather longer than the thorax, and serrated ; thorax slightly convex, finely 

 punctate^ glossy: elytra punctate-striate, with the interstices finely punctured, 

 pubescence as if obliquely abraded a little behind the middle, forming by the 

 union of the elytra an obscure letter V. : legs black. 



This species, which might, without due attention to the structure 

 of its antenna?, readily pass for an immature state of Perimecus 

 fulvipes. was discovered many years since in " Lee-wood, by Mr. 

 Millard." — Marsham MSS. It was afterwards taken by Mr. 

 Bydder, in the New Forest, and again near Lyndhurst, by Mr. 

 Weaver, who captured eight or ten specimens in the summer of 

 1826. 



Sp. 2. niger. Niger nitidus fusco-hirtus, elytris leviter striatis, bast sulcatis. 



(Long. corp. 4g — 6 lin.)
