size, oblong, depressed, form, very large head and short thorax, which is 

 not channelled, and also by its very long antenna? and general sculpture. 



P. ruulosum, All. (fit-scum, Er.). Oblong, convex, rather narrow, 

 fuscous, thickly clothed with pale pubescence, with very deep rugose 

 sculpture, especially on elytra ; thorax, very short, not channelled ; elytra 

 narrow, not or scarcely broader than head and thorax, antennae rather 

 long and slender, pale ferruginous, legs testaceous ; this species is rather 

 closely allied to P. Kunzei, but differs in its narrower form, more 

 rugose sculpture, much shorter thorax, and longer and more slender 

 antennae. L. ~ mm. 



Very rare ; Gumley, in moss (Matthews) ; Scotland, Tay district. 



P. Spencei, All. (angustatum, Er. ; oblougum, Gyll.). Elongate- 

 oval, rather convex, fuscous-black or black, clothed with rather 

 long greyish hairs ; head moderate, eyes prominent, antenna? moderate, 

 more or less pitchy ; thorax rather short, transverse, very little broader or 

 wider than head, not channelled, broadest before base, with rather large, 

 remote tubercles, sides and angles strongly rounded ; posterior margin 

 slightly reflexed; scutellum small ; elytra rather long, oval, broader than 

 thorax, deeply asperate in transverse rows, the asperations not being very 

 close ; legs pitchy ; under-side pitchy, with mouth, coxre, and apex of 

 abdomen lighter. L. f mm. 



In vegetable refuse, moss, &c. ; occnsionnlly by evening sweeping; locally common ; 

 Esher, Lee, Tonbridge; Hastings; Glanvilles Wootton ; Knowle, iiepton, Matlock, 

 and other Midland localities; Cheshire; Scotland, Solwsiy and Dee districts; iu 

 Bretby Wood, Repton, I once took a large number of Trichopterygidaj under some 

 refuse in a ride; these all proved to be T. grandicolli.i and P. Spencei; I do nob 

 know whether there is any connection between these insects except similarity of 

 habitat; they are both, probably, generally distributed in England. 



P. marg-inatum, Aube. Very closely allied to P. Spencei, but dis- 

 tinguished by its usually larger size, larger and wider thorax, which is 

 more closely sculptured, and is widest at base, and has the posterior 

 margin rather strongly reflex ed ; the antennae also are more lightly 

 coloured, and the sculpture of the whole body is finer. L. f-| mm. 



Rare ; taken by Mr. Matthews and Mr. Crotch in the Cambridgeshire and Norfolk 

 Fens, in 1868, and by Mr. Matthews at Forest Hill, Kent, in rotten leaves; also by 

 Mr. Blatch in Sherwood Forest, under bark. 



P. caledonicum, Sharp. Elongate- oval, convex, rather shining, 

 colour variable, usually dirty testaceous, but sometimes more or less 

 fuscous, head and thorax darker than elytra ; upper surface rather thickly 

 clothed with long pale hairs; head large, eyes large and prominent, 

 antennae long and very slender, yellow ; thorax broader than, and rather 

 narrower than elytra, broadest at middle, with the sides strongly rounded 

 in front, and constricted behind, without channel, but sometimes with an 

 obsolete impression on each side near the base, with rather thickly-set,
