.] LAMELL1CORNIA. 25 



broader and more diffusely punctured on disc, and the metasteraum 

 impressed. 



In sheep's or deer's dunp in woods; rare ; Scotland, Tay and Dee districts (Brae- 

 mar, Avieraore, Ac.). Erichson records it as not rare in the Thiiriuger Waldo in 

 deer's dung. 



A. plagriatua, L. Elongate, narrow, convex, subcylindrical, 

 shining black with a very slight aeneous reflection ; head finely and 

 more or less thickly punctured, with the frontal tubercles almost 

 absent ; the central one, however, is plainly traceable ; antennae brown 

 with blackish club ; thorax with sides almost straight, very finely 

 punctured, with large punctures intermingled ; these are diffuse on disc, 

 but much thicker at sides ; scutellum punctured at base ; elytra either 

 entirely black, or with a large oblique red patch on disc of each, with 

 fine crenate striae, interstices large and flat scarcely visibly punctured ; 

 legs variable, either black with tarsi ferruginous, or reddish-brown with 

 blackish femora, or entirely reddish-brown. L. 2|-3 mm. 



Male with the metasternum slightly impressed in middle and 

 pubescent. 



Damp places ; under stones, in flood refuse, &c. ; rarely in dang ; local, bat not 

 uncommon where it occurs ; Deal ; Sheerness ; Dover ; Hastings ; Bannonth ; 

 Wisbeach ; Peterborough ; Norwich ; Liverpool : the form with immaculate elytra 

 appears to be the commonest ; this was introduced by Mr. Crotch (Proc. Ent. Soc. 

 London, Nov. 19, 1866) as A. niger, GUI. ; that species, however, docs not appear to 

 have been hitherto found in Britain ; it is closely allied to A. plagiatus, but is rather 

 larger, and has no aeneous reflection (this, however, is often scarcely visible in A. 

 plagiatus}; the posterior tarsi, moreover, have the exterior spar shorter, and the 

 metasternum is more finely and sparingly punctured, and not pubescent in the male. 



A. lividus, 01. Oblong, convex, shining, of a livid testaceous 

 colour, with the base of the head, the disc of thorax, and the suture of 

 elytra, together with a more or less broad and cloudy band on each of 

 the latter, dark ; as a rule the dark band covers the greater part of the 

 elytra, leaving the apex, margin, and a line before suture light ; head 

 finely punctured, rugose in front, antennae and palpi testaceous ; 

 thorax extremely finely punctured with fine and scattered larger punc- 

 tures which are more numerous at sides; elytra with rather fine but. 

 distinctly crenate striae, interstices exceedingly finely punctured ; legs 

 short and stout, reddish- brown with femora yellow. L. 3j-i mm. 



Male with central frontal tubercle larger, and the metasternum 

 impressed in the middle. 



In dung, manure heaps, <to. ; very local ; London district, not uncommon, Norwood, 

 Lee, Dan-nth Wood, Sittingbourne, Greenwich, Forest Hill ; Kingsgate, nenr 

 Margate, in abundance (T. \V >.! ; Holy Inland ; Northumberland district, rare, 

 Heaton and Long Benton. 



A. porous, F. Oblong, rather depressed, black, dull, with the 

 elytra of a dark red colour ; head comparatively small, very thickly 

 punctured, antennae yellow with greyish club, palpi reddish-yellow ;
