92 SERRICORNIA, [ Eater. 
borough; Chat Moss; Northumberland and Durham district; Scotland, local, 
Solway, Forth, Clyde, Tay, and Moray districts. 
E. tristis, L. Black, with the base and outer margins of elytra 
and a large longitudinal patch behind seutellum reaching to about the 
middle of a dirty yellowish or brownish-yellow colour; upper surface 
clothed with blackish pubescence; head thickly punctured, antenne 
fuscous with base a little lighter, feebly serrate ; thorax about as long 
as broad at base, narrowed in front, thickly and distinctly punctured, 
with a fine and more or less distinctly traceable longitudinal furrow ; 
elytra gradually narrowed towards apex, with punctured strie, inter- 
stices coarsely punctured and transversely rugose ; legs black or pitchy 
with the tibie lighter, and the tarsi reddish; the yellowish colour on 
elytra is somewhat variable in extent. L. 7 mm. 
In mountainous districts, under bark of spruce fir; very rare; Scotland, High- 
lands, Tay district (Rannoch). 
E. nigrinus, Payk. Black, unicolorous, shining, clothed with fine 
greyish or greyish-brown pubescence; head thickly and distinctly 
punctured, antennz pitchy, rather slender, feebly serrate, third joint 
conical, about twice as long as second; thorax narrowed in front, some- 
what convex, finely and rather sparingly punctured on disc, more 
closely at sides, posterior angles short; elytra with distinct punctured 
striea, interstices punctured and very distinctly rugose transversely ; 
legs pitch-brown with tarsi lighter. L. 5-65 mm. 
Under bark of pine and fir; occasionally in oaks; rare; Tooting Common (S. 
Stevens) ; Cobham; Burnt Wood, Staffordshire (Chappell) ; Scotland, local, High- 
lands, I'ay, Dee, and Moray districts (Aviemore, Rannoch, &c.). 
E. wthiops, Lac. (scrofa, Germ.; rufitarsis, Desv.). This species 
is allied to the preceding, but is larger and broader, with the antennz 
longer and stonter; the third joint of the latter is cylindrical, double 
as long as the second; thorax hardly shorter than broad at base, 
moderately thickly and coarsely punctured; elytra with punctured 
strie, interstices somewhat convex, punctured, but scarcely transversely 
rugose; legs black with tarsi reddish or pitchy; the general form and 
coarser punctuation as well as the larger size will easily separate this 
species from the preceding. L.10 mm. 
Under bark of deciduous trees; rare; Windsor Forest (Desvignes and Turner). 
ISCHNODES, Germar. 
This genus has by many authors been included under Megapenthes, 
from which it may be at once distinguished by the more strongly serrate 
antenna, of which the second joint is very small and very much shorter 
than the third joint ; the genus contains one Huropean species which 
is very rare in Britain,
