much finer punctuation and obtusely-rounded posterior angles of the 

 thorax. L. 2^-3 mm. 



In saudpit!5, on sandy cliffs near the coast, &c. ; very local, I)ut sometimes common 

 where it occurs ; Strood and Upnor, Kent (in profusion, J. J. Walker) ; Wells, 

 Norfolk; Lowestoft;; Southend; Isle of Wight, Luccombe Chine, &c. ; Scotland, 

 rare, Solway district, " near Dumfries, W. Lennon ;" Ireland, Killiney, near 

 Dublin. 



B> crassicollis, Lac, filiim. Ileer. {Blediodes crassicolUs, Muls. ct 

 Rey). Shining black with the elytra bright red or chestnut-red with the 

 scutellary region sometimes a little darkened ; head nearly as broad as 

 thorax^ very finely shagreened, with an obsolete fovea on vertex ; antennae 

 rather short, red ; thorax about as long as broad, truncate at apex, with sides 

 subparallel until posterior third where they are strongly narrowed to base, 

 posterior angles blunt, but not rounded,* upper surface rather strongly 

 and thickly punctured, with the interstices of the punctures scarcely 

 shagreened, with no central channel but in its place a smooth slightly 

 raised line ; elytra only a little longer than thorax, rather strongly and 

 thickly punctured ; hind body evidently widened behind, very finely 

 shagreened, and also punctured at the sides ; legs reddish-testaceous 

 L. 3| mm. 



Male with the sixth ventral segment of hind body broadly sinuate on 

 apical margin, the sinuation being filled with membrane, and furnished 

 on each side with a short stout projecting tooth. 



Sandy places near the coast ; very local ; has only hitherto occurred near Deal 

 (Wahner, &c., Power and C. G. Hall) ; it is rather rare, although widely distributed 

 in France, and is by no means an exclusively maritime species, appearing rather to 

 frequent hilly and woody localities where it is found on the banks of streams, 

 marshes, &c. 



B. dissimilis, Er. (Blediodes disshnilis, Muls. et Eey). Shining 

 black with the elytra chestnut-red, or reddish-testaceous, with the suture 

 more or less broadly dark ; head nearly as broad as thorax, very finely 

 shagreened, antennce short, reddish-testaceous, lighter at base, penulti- 

 mate joints transverse ; thorax as broad or very slightly broader than 

 long, truncate at apex, with sides not quite so parallel as in B. crassicollis 

 and more rounded behind, posterior angles almost if not quite rounded, 

 upper surface with central channel replaced by a smooth and some- 

 what raised line, rather strongly and thickly punctured, with the inter- 

 stices rather plainly shagreened under a high magnifying power ; elytra 

 considerably longer than thorax, rather strongly and thickly punctured ; 

 liind body widened behind, shining black with apex reddish, very finely 

 shagreened, and obsoletely punctured at sides ; legs reddish- testaceous, 

 with the posterior coxre sometimes darker. L. 3|-3| mm. 



* This character is a somewhat difficult one to perceive, although an important 

 one in the liledii : with regard to this particular species I agree with Rey ; Erichsou 

 says of the posterior angles, fortement arrondis, Lacordaire asaez arromlis, Kraatz 

 Ires ohtus, Fauvcl obtus.
