to Ml-. Waterlionso it is commou near LoiulcMi, but Mv. Clininpion ppcaks of it as 

 r;\re in tlie Lnulon district. Mr. Blatch snys tliat he has met with it in some numlicra 

 ill Sherwood Forest uiuler hark of faUen trees. 



E. Klrliji is only a form of this species, whicli has been chiefly- 

 separated on the ground that the frontal furrows converge strongly, 

 "whereas in E. nanus they are parallel ; there is, however, no real 

 difference between the insects, as the frontal fun^ovvs are very variable, 

 and specimens may be found that are intermediate as regards their 

 formation. E. nanus is variable both in size, colour, and sculjiture. 



E. sang-uineus, Denny. In structure this species most closely 

 resembles E. sirjnatus, and is only distinguished from that species by its 

 black or pitchy-black colour and rather larger size, and by having the 

 lateral basal foveaj of the thorax a little deeper ; immature specimens are 

 often found, which cause great confusion, as they are entirely red in 

 colour ; in general appearance E. sanguineus closely resembles E. nigri- 

 cans, but it may easily be known from this species by its shorter 

 antennae ; the head, moreover, is not so short in proportion to its width ; 

 the antenucB and legs are ferruginous or reddish-testaceous. L. 

 11-11 mm. 



Male with the penultimate ventral segment furnished with a largo 

 deep fovea in the middle, on each side of which there is a minute 

 tubercle. 



In haystack and vegetable refuse, dung-heaps, hot-beds, &c. ; very rarely under 

 decaying logs or hark; rather common and generally distributed in the London, 

 Southern, and Midland districts ; York; Manchester; Withington, Cheshire; Scot- 

 land, rare, in decaying hay, Solway district only, 



E. piceus, ]\rots. {nigricans, Chaud.; Dennii, Wat; sulcatnlus, 

 Saulcy). Pitchy-blacky shining, antennte, palpi, nnd legs reddish-tes- 

 taceous, very rarely pitchy ; head as broad as thorax, sparingly and 

 finely ])UDctured on disc, strongly and thickly at the sides, rounded and 

 narrowed behind eyes ; antennae rather long ; thorax very feebly jDunc- 

 tured, rather broader than long ; elytra plainly broader than head and 

 thorax, a little longer than together broad, scarcely punctured, dorsal 

 stria reaching middle ; abdomen with basal depressions broad and 

 shallow. L. l|-l|^mm. 



Male with the posterior femora thickened, metasternum channelled 

 and bearing a blunt tubercle on each side; fourth ventral segment of 

 abdomen somewhat produced and bisinuate in middle of apical margin ; 

 fifth, tuberculate on each side at base ; sixth, with a transverse furrow 

 at base, emarginate at apex ; in the female the metasternum is feebly 

 channelled. 



Under hark and in decaying wood; very rartly in hot -beds; London district, not 

 common, but rather widely distributed ; Darenth Wood, St. Mary Cray, Chatham, 

 Hawkhurst, Forest Hill, &c. ; Loughton, and Ulting, near Maldou, Essex ; The Holt,
