78 cLAViooRNiA. [Scijdmcenus. 



London disf.rict, <and the Southern and Midland Counties ; rarer further north, 

 and apparently very rare in the Northumberland district ; it is not recorded from 

 Scothmd. 



S. collaris, Miill. Black, shining, very like the preceding iu 

 general appearance, but narrower and more elongate, with the thorax 

 longer than broad and less gradually rounded in front, and the elytra 

 long oval and less obtuse at apex ; the humeral fold is very short and 

 indistinct ; the male anterior femora, moreover, are only gradually 

 dilated, and not angled but rounded externally, and broadest near the 

 middle. 



In moss, &c. ; generally distributed and common throughout England, and 

 probably Ireland, and not rare in Scotland, Solway, Tweed, Forth, and Dee districts. 

 L. l^-ii mm. 



Immature specimens often occur of this and the preceding species 

 •which are entirely rufo-testaceous and cause great confusion 5 the form 

 and sculpture Avill, however, serve to distinguish them. 



S. pusillus, Miill {flavicornis, Mots.). Long oval, convex, smaller 

 than the two preceding species, black, shining, clothed sparingly with 

 rather fine yellow pubescence, antennse and legs reddish-testaceous, 

 femora usually darker, palpi and tarsi yelloAV ; head narrower than 

 thorax, antennse moderate, with the two penultimate joints somewhat 

 transverse ; thorax convex, feebly cordiform, slightly longer than broad, 

 impunctate, with four foveae at base of which the inner pair are some- 

 what larger than the others ; elytra long oval, very plainly punctured, 

 with two fovese at the base of each ; humeral fold short and not distinct. 

 L. li-lj mm. 



Male with the anterior femora, gradually dilated, and acutely angled 

 externally at apex. 



In moss, flood refuse, &c., especially about river banks ; rare ; Chatham, Eghara 

 (Sun-ey), Mickleham, Walton-ou-Thames, Sydenham, Staines, Tottenham ; Hawk- 

 hurst; Glanvilles Wootton ; Devonshire; Buddon Wood, Leicestershire (in nests of 

 Formica rufa) ; Durham (in hotbeds at Gilesgate Moor) ; Scotland, very rare, Solway 

 district. 



This species closely resembles in general appearance small specimens of 

 /S. coUaris, which often do duty for it in collections, but apart from its 

 size it may be known by the much plainer punctuation of the elytra, the 

 shape of the basal thoracic foveae (of which the inner pair are larger than 

 the outer in S. imsilliis, whereas in S. collaris the inner pair are more or 

 less obsolete), and the shape of the anterior femora in the male ; all the 

 femora appear to be more dilated at apex than in S. collaris. 



S. Poweri, Fowler. This species (described by myself in the 

 Entomologist's Monthly Magazine, xx. 247) is closely allied to S. pnsillns, 

 but may be easily distinguished by its colour which is dark reddisli- 

 brown (as in S. clongatulus), and by the less coarse and diffuse punctuation
