DESCRIPTION OP A NEW SPECIES OF ELATER. 
BY E. C. EYE. 
Elater coccinatus, n. sp. 
Afer, suh-parallelus, depressus, fmco pilosus ; elytris sanguineis, 
IcEvius punctato-striatis, infcrstitiis planis ; prothorace longiori, lateribus 
a hasi tertiam usque ad partem anteriorem fere parallelis, inde gradatim 
angustatis, omnium creherrime p)unctato, disco solo nitidiusculo, lateribus 
omnino hand nitidis, postice canaliculato, supra scutellum foveolato ; 
antennis pedibusque nigro-piceis, — Ms tarsis, illis articulis secundo ter- 
tioque rufescentibus. Long. corp. ^\ lin. 
This insect (as mentioned at p. 233 of the present vol.) is the 
" Elater, 5 nov. sp. .?" of Mr. Waterhouse's Catalogue. Single speci- 
mens of it have been taken by that gentleman (in a rotten tree) in 
Kensington Gardens, and by Mr. T. H. Griesbach and the late Messrs. 
A. Griesbach and E. Sharman in "Windsor Forest. 
There appears, also, to be a specimen of it in the British Museum 
Collection. 
From E sanguineus, Linn., this species may be distinguished by its 
smaller size and narrower and more parallel shape ; its longer thorax, 
which is duller and more densely punctured, with not quite so dark 
pubescence and a more abbreviated and less evident dorsal channel ; 
and its less deeply striated elytra, of which the interstices are flatter. 
From E. lythropterus, Germ., the above characters will also serve 
to separate it, except that the pubescence of its thorax is darker, and 
its dorsal channel is quite as evident behind. The joints of its antennre 
are, moreover, longer and not so broad. 
I have not seen E. cinnabarinus, Esch ; which, however, from its 
confusion by Candeze with E. lythropterus (with which E. satrapa, 
Kies., appears to be identical), must be too closely allied to that insect 
to have any connection with E. coccinatus. 
From E.pomonce, Staph., which it rather exceeds in size, its longer 
antennae, longer, more parallel, very much duller and more closely 
punctured thorax (of which the pubescence is considerably darker), and 
the slighter strife and flatter interstices of its elytra readily separate it. 
Its immaculate elytra distinguish it at once from the type form of 
E. sanguinolentus, Schr. ; and its much longer, more parallel, much 
duller and more closely punctured and posteriorly canaliculated thorax 
serve to separate it from the plain form of that species, — which it, 
perhaps, resembles superficially more than any other. Its antennae.
