Eai>ledus.} CLAVICOHNIA. 105 



to Mr. Watcrhousc it is common near London, but Mr. Champion speaks of it as 

 rare in the London district. Mr. Blatch says that lie has met with it in some numbers 

 in Sherwood Forest under bark of fallen trees. 



E. Kirbyi is only a form of this species, which 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 furrows are very variable, 

 and specimens may be found that are intermediate as regards their 

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



X3. sang-uineus, Denny. In structure this species most closely 

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

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

 lateral basal fovere 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 antennae and legs are ferruginous or reddish-testaceous. L. 

 li-l| mm. 



Male with the penultimate ventral segment furnished with a large 

 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 bark ; rather common and generally distributed in the London, 

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

 liuid, rare, in decaying hay, Solway district only. 



13. piceus, Mots, (nigricans, Chaud.; Dennti, Wat ; sulcatulus, 

 Saulcy). Pitchy-black, shining, antennae, palpi, and legs reddish-tes- 

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

 finely punctured on disc, strongly and thickly at the sides, rounded and 

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

 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. lf-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 bark and in decaying wood; very rarely in hot-beds; London district, not 

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

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