93 SERRICORNIA. [fXater. 



borough; Chat Moss; Northumberland and Durliain district; Scotland, local, 

 Solway, Forth, Clyde, Tay, and Moray districts. 



E. tristis, L. Black, with the base and outer margins of elytra 

 ami a large longitudinal patch behind scutellum reaching to about tho 

 middle of a dirty yellowish or brownish-yellow colour; upper surface 

 clothed with blackish pubescence; head thickly punctured, antennae 

 fuscous with base a little lighter, feebly serrate ; thorax about as long 

 a-? 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 striae, inter- 

 stices coarsely punctured and transversely rugose ; legs black or pitchy 

 with the tibiae lighter, and the tarsi reddish ; the yellowish colour on 

 elytra is somewhat variable in extent. L. 7 nim. 



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, antennae 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 

 striae, 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); Cobliaui ; Burnt Wood, Staffordshire (Chappell) ; Scotland, local, High- 

 lands, Tay, Dee, and Moray districts (Avietnore, Banuoch, &c.). 



E. aethiops, Lac. (scrofa, Germ.; nifitarsis, Desv.). This species 

 is allied to the preceding, but is larger and broader, with the antennae 

 longer and stouter; 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 

 Hirice, 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 Meyapenthe*, 

 from which it may be at once distinguished by the more strongly serrate 

 antennae, of which the second joint is very small and very much shorter 

 than the third joint ; the genus contains one European species which 

 is very rare in Britain.
