JRhitsophagvs.] CLAVICORNIA. 



disc of thorax sometimes darker ; thorax longer than broad,, widest in front r 

 very slightly contracted behind, with anterior angles very plainly marked,, 

 with coarse and diffuse punctuation ; club of antennae oval ; elytra de- 

 pressed, parallel to middle and thence gradually narrowed, with rather 

 weak and comparatively finely punctured striae ; the species may be easily 

 distinguished from R. depre&us, which at first sight it much resembles r 

 by the much coarser punctuation of the thorax, and from R. parallelocollis 

 and R. ferruyineus by its average smaller size, and the more finely and 

 less closely punctured strife of elytra ; the thorax, moreover, is not quite 

 as closely punctured on disc as in these two species. L. 3 mm. 



Under bark, at sap, &c. ; not common ; Chatham, Sheerness, Darenth, Mickleham, 

 Shirley, Esber, Farnhuin, Parley, &c. ; Ipswich; St. Peter's, Kent (in decaying pota- 

 toes, one specimen, T. Wood); Hastings; Wey mouth ; New Forest; Portland; 

 Devon; Salt'ord Priors; Bewdley ; Sutton Park, Birmingham; Church Stretton ; 

 Buddon Wood, Leicestershire ; Sherwood Forest ; Scotland, rare, amongst old wood, 

 Solway district only ; Ireland, Galway ( J. J. Walker). 



R. parallelocollis, Er. Larger on the average than the preceding, 

 and as a rule of a darker ferruginous colour, with the disc of thorax and 

 hinder half of elytra very often clouded with blackish-brown ; head 

 nearly as broad as thorax ; tliorax longer than broad, widest in front, 

 very slightly narrowed behind, coarsely punctured ; elytra depressed, 

 especially in the middle, with rather strong plainly punctured striae ; the 

 species most closely resembles R. fernir/ineus, from which it may be 

 known by its more depressed form and larger head ; occasionally 

 specimens are found which are coloured almost like R. dispar ; the latter 

 species, however, is less depressed and narrower, and has the thorax 

 evidently longer and less coarsely punctured. L 3-4 mm. 



Under bark, at sap, in fungi, &c. ; local ; Darenth Wood, Mickleham, Forest Hill, 

 Esher, Shirley, Chatham ; Regent's Park, in a tree infested by Cossus ; Dean Forest ; 

 Sherwood Forest ; the late Archdeacon Hey once found it in numbers in a cemetery 

 near York in a fungus (Copris comatus) in company with Atomaria fimetarii ; 

 Northumberland and Durham district, not rare, on the walls and tombstones of grave- 

 yards ; Scotland, rare, Solway district. It has lately been recorded as abundant iu 

 France in coffins in grave-yards, buried at some depth below the ground. 



R. ferrug ineus, Payk. Eather dark ferruginous, unicolorous ; head 

 small, considerably narrower than thorax ; thorax longer than broad, 

 scarcely narrowed behind, very strongly punctured ; elytra convex 

 cylindrical, with strong and strongly punctured striae ; under-side deeply 

 punctured, especially at sides ; the species may be known by its some- 

 what narrow head, and convex cylindrical elytra, which are evidently 

 more strongly striated and punctured than in the allied species. L. 3|- 

 4| mm. 



Under bark and at sap of freshly cut firs, &c. ; somewhat local, but widely dis- 

 tributed throughout England; Scotland, common, Solway, Tay, Dee, Moray, and pro- 

 bably other districts; Ireland, near Dublin; it also occurs uuder bark of oak near the 

 burrows of Cos.ius Ugniperia.
