Pcederus."] staphyliniDjE. 323 



Marsliy places, usually on or near the banks of rivers ; at roots of grass, in moss, &c. ; 

 local ; SnoiUand (Kent), Weybridge, Walton-on-Tliames, Chobliain, Dagenliain, Amber- 

 ley, Sunbury ; Henley ; Hastings ; Glanvilles Wootton ; Winchester ; I'ortisliead ; 

 Swansea ; Oxfordsliire ; Wicken Fen and fen districts generally ; York ; not recorded 

 from the extreme north of England, or from Scotland or Ireland. 



P. fuscipes, Curt, {longipennis, Er,). Considerably smaller, and of 

 a generally more delicate appearance than the preceding, with the thorax 

 more parallel-sided, less narrowed behind_, and taken as a whole evidently 

 narrower in proportion to the elytra ; the scutellum is usually darker ; 

 the elytra are distinctly longer in proportion to the thorax, and are a 

 little more thickly punctured ; the tibiae are a little darker at their base, 

 and in fact are seldom entirely testaceous, and occasionally quite dark, 

 at all events the intermediate and posterior pairs. L. 6 mm. 



Marshy places, at roots of grass and plants, in moss, flood refuse, &c. ; local, but 

 sometimes abundant where it occurs; Snodland (Kent), in profusion (J. J. Walker); 

 Hastings; Eastbourne; Isle of Wight, Luccombe Cliine, &c. ; New Forest ; Shipton 

 Ley, Devon ; Falmouth ; St. Mary, Scilly Islands ; Bala, North Wales (by beating) ; 

 in profusion on and about an old wall between Dolgellp and Barmouth (J. T. Harris) ; 

 Scotland, very local, Solway district, "taken in abundance by W. Lennox at Caerlave- 

 rock " (Sharp, Scot. Nat. iii., p. 35) ; Ireland, Murrough of Wicklow. 



P. calig'atus, Er. This species may be easily distinguished from 

 the preceding by its entirely black tibiae ; apart from this it may be 

 known from the two preceding species, which it resembles in general 

 form, by its rather shorter elytra, which are more strongly and less closely 

 punctured; the thorax is less narrow and less parallel than in P. fuscipes, 

 and the penultimate joints of the antennae are a little shorter ; from P. 

 littoralis it may be at once known by its dark tibias, testaceous mandibles, 

 and the different shape of the thorax, as well as by its smaller size and 

 shorter and less robust form. L. 6 mm. 



Marshy places, at roots of grass, and especially in sphagnum ; very local, but some- 

 times common where it occurs ; Esher ; Wimbledon ; New Forest (taken in rather 

 scanty numbers in sphagnum near Lyndhurst on May 1st, 1886, by Dr. Sharp, Mr. 

 Gorham, and myself). 



In Stephens' Illustrations, vol. v., p. 281, two species are mentioned, viz. 

 Fwderus rtificoUis, F., and Pcederns sangvinicoUis, Steph., which are remarkable 

 for having the hind body entirely black or bluish black ; these two species form the 

 sub-genus Pcederidiis of Rev, which is separated by that author from Paderus on the 

 ground that the base of the hind body beneath is raised in a slight and blunt keel, and 

 that the mefosternal process is not keeled, whereas in Paderus the keel at base of hind 

 body is conspicuous and sharp, and the mesosternal process is always more or less 

 keeled ; P. nificollis is mentioned by Stephens as having been taken near Barmouth 

 and Swansea, and on other parts of the Welsh coast, and as having been found in plenty 

 at the first-menti(med place, and P. sanguinicollis is first described by him on specimens 

 from Devonshire, and is mentioned as occurring in Glamorganshire ; they are given as 

 distinct species in Waterhouse's catalogue, but have long been omitted from our lists, 

 and I know nothing of their history as British. P. rujicoUis (with which P . longi- 

 corn'is, Aube = savgttinicollis, Steph., is united by R-y and other authors) appears to 

 be a common species in France.*
