Choleva."] CLAVICOENIA. 61 



C. longipennis, Chaud., appears to be a variety of this species ; it 

 has the elytra more convex and dilated and the striae of the elytra more 

 feebly marked; Erichson's C. fuliginosus is also referred by many 

 authorities to C. nigricans, but there seems to be some doubt regarding 

 the matter. 



C. long-ilia, Kell. (pilicornis, Thorns.). Elongate, black, oval ; 

 antennae as long as head and thorax, rather robust with the basal joints 

 and the terminal joint, at least at apex, reddish testaceous, joints 6-8 

 of nearly equal length; thorax thickly punctured, clothed with 

 yellowish-grey pubescence, with sides rounded, and narrowed in front 

 and behind, posterior angles right angles ; elytra long, indistinctly 

 striated, finely pubescent, appearing, like many of the allied species, to 

 be covered with a kind of bluish bloom ; legs blackish-brown or ferru- 

 ginous, tarsi lighter. L. 4-4-1- m m. 



Under moss, in fungi, dead birds, &c. ; rare; Manchester district; Ripon (Wat.er- 

 house) ; Manchester district; Hartlepool; Wellington, Northumberland; Scotland, 

 rare, Forth and Sol way districts; Ireland near Waterford (Power). 



Murray regards this species as a variety of C. tristis ; it differs, how- 

 ever, considerably in shape, and in having the club of the antennae less 

 distinct ; it appears to be identical with C. pilicornis, Thorns. 



C. coracina, Kell. A rather small, black species, which may be 

 distinguished from all the succeeding species except C. mono, by having 

 the last joint of the antennas as broad as the penultimate, and from the 

 latter species by its smaller size, shorter elytra, and unicolorous club of 

 the antennas ; head and thorax thickly and finely punctured, with fine 

 short yellowish pubescence, the latter almost as broad as elytra, broadest 

 in middle, with the posterior angles right angles, not projecting, and 

 appearing at first sight obtuse ; elytra short oval, without yellow 

 pubescence at base of elytra, but with the visual ashen-grey or bluish 

 bloom, thickly punctured, indistinctly striated ; legs pitchy-red. L. 

 3-3| mm. 



The male has a small prominence on the under side of the anterior 

 femora. 



In dead animals, &c. ; rare in England ; Shirley near Croydon j Esher ; Bewdley; 

 Coleshill ; Knowle ; Needwood near Burton -on -Trent ; Ripon (Waterhouse) ; North- 

 umberland district, "near Wooler, very rare;" Scotland, not uncommon, Solway, 

 Forth, Dee, Moray, and Shetland districts. 



C. morio, F. This species may be recognized by its rather long 

 oblong-oval shape, obtuse posterior angles of thorax, and the colour of 

 the antennae, which, as a rule, have the first two joints ferruginous, and 

 the rest, with the exception of the last, blackish ; the last joint is yellow ; 

 rarely however the whole antennas are ferruginous, and this fact, as in 

 other species, sometimes gives rise to confusion ; the general colour is 

 black with yellowish grey pubescence on the thorax, and an ashy-grey 

 bloom on the elytra ; head and thorax thickly and finely punctured, the
