Dulwicli ; Waltonon-Naze ; King-Jgate ; Bognor, in profusion ; Newliavcn ; Hustings ; 

 Shorehani ; Porlland and neighbourhood, plentiful by sweeping; Ghmvilles VVootou ; 

 it appears to be confined to the south-eastern and southern coasts. 



S. cotus, Saulcy {=B. Lefebonci\ Sharp's cat. Isted. necAn])6). This 

 species very ckisely resembles tlie preceding, but is of a somewhat longer 

 and narrower form, and has the abdomen less closely punctured ; it may 

 also be known by the fact that the first visible segment of the abdomen 

 is simple in both sexes and not tuberculate at apex in the male ; it is 

 very closely allied to B. Lefehvriei, and the specimens first taken in 

 Britain were referred to that insect. L. 1| mm. 



On the banks of rivers, vei-y local ; Scotland, Sohvay district, in sandy places by 

 the Nith and Kew ; it appears to be peculiar to Scotland. 



S. hsematica, Reich, (emarginata, Forst. ; Brachyr/hifa hcematica, 

 Thoms). Entirely rufous, with the palpi reddish-testaceous, elytra 

 brighter ; head triangular, smooth and shining, frontal fovcie deep ; 

 antennge moderately long, last joint ovate ; thorax about as broad as long, 

 smooth and shining, widest before middle, rather gradually narrowed to 

 base, with three large equal basal foveas ; elytra nearly quadrate, scarcely 

 visilily punctured ; abdomen as long as elytra, margined, smooth and 

 sliining ; legs reddish, tarsi paler. L. l|-2 mm. 



^[ale with the trochanters and tibite simple and the first visible dorsal 

 segment produced in a lobe on each side at apical margin, the space 

 between the lobes being more or less deeply emarginate ; this cliaracter 

 is variable, the lobes being sometimes rounded, and sometimes rather 

 sharp ; occasionally on the upper surface of each lobe there is a more 

 or less deep fovea, and sometimes the emargination between the lobes is 

 bidenticulate : Aube has named three varieties as duftata, perforaia, 

 and hideaticulata. 



Marshy places ; in flood refuse, &e. ; local, but occasionally abundant; more fre- 

 quent about the banks of large rivers than elsewhere; Chatham, Barnes, Egham, 

 Staines, Walton-ou-Thames ; Hastings; Glanvilles Wootton; New Forest ; Barnstaple, 

 Devon (recorded as t.aken in company with Formica Jiava and 3It/rmica rubra) ; 

 Salford Priors; Tewkesbury; Hartlebury, Woi'cestersbire ; Repton ; Church Stretton, 

 &c., Cheshire ; Stretford, near Manchester, at roots of trees in winter ; banks of 

 Mersey; Northumberland district, banks of the Irthiug, rare ; Scotland, very rare; 

 has only occurred in the Sohvay district at the estuary of the Nitli below New Abbey ; 

 Ireland, Galway (Walker). 



S. juncorum, Leach. {Dierohiajimcorum, Thoms.). This insect in 

 colour and general appearance very closely resembles a small specimen of 

 the preceding, but may at once be known by having the central basal 

 fovea of the thorax minute and much smaller than the lateral ones Avliich 

 are large ; its general form is shorter and broader in proportion, and the 

 head and thorax, especially the latter, are thickly and distinctly punctured ; 

 the elytra and abdomen also are finely punctured, the punctuation being 

 distinctly visible under a high magnifying power ; in the male the an- 

 terior trochanters are armed with a short spine and the intermediate ones
