Sevenoaks, Haiup.ult Forest ; Devonshire ; Bi'wdley Forest ; Bretby Wood, near 

 IJopton ; Scarl)orou<?li ; Kastliam, near Liverpool ; Drinkwater Park and other localities, 

 Manchester ; Scotland, very rare, Tweed, Forth, and Tay districts. 



BI. formosus, Grav. This species differs from the preceding in 

 being smaller and narrower, and with the elytra somewhat shorter ami 

 less closely punctured ; the insect is winged, whereas ]\I. indinans is 

 apterous ; in the male the seventh ventral segment is subtruncate on' apical 

 margin Avith a small central angular emargination which is partly tilled 

 with membrane, L. 5|-6 mm. 



Very rare and somewhat douhtful as British ; Stephens (111. Mand. v. 1G8) says, 

 " Taken near Swansea, and I believe within the metropolitan district," and Bold 

 (Catalogue of Insects of Northumberland and Diirliam, p. 34) has the record, " Rare. 

 One specimen taken in a quarry near Fuifar Bar, Mr. J. Hardy, November ; " he 

 appears, however, to be somewhat doubtful of the species; no other records are known, 

 and the species does not occur in France or the Netherlands. 



BRVOFORUS, Kraatz. 



Of this genus there are about as many species at present known as in 

 the preceding, and their distribution is similar ; tlie three British species 

 are among our rarest indigenous insects. 



I. Thorax smooth or almost smooth ; size smaller. 



i. Elytra rugoscly striate or punctate between the series ; 



fourth joint of autennffi oblong B. ErrGlPE>'NIS, Prtncf. 



ii. Elytra smooth between the series; colour lighter ; fourth 



joint of antennce not longer than broad B. CASTANETTS, JIardy. 



II. Thorax very finely and rather thickly punctured ; size 



larger B. CERNUTTS, Grav. 



B. rugripennis, Pand, Fusiform, not convex, shining black, with 

 the thorax and elytra dark red, the former usually darker on disc, and the 

 apical margin of the segments of hind body reddish testaceous ; head shoi t 

 oval, almost smooth, shining black, Avith mouth parts testaceous ; antenna) 

 as long as head and thorax united, somewhat tliickened towards apex, 

 dark, with the first two or three joints reddish testaceous, "penultimate joints 

 plainly transverse ; thorax transverse, strongly narrowed in front, with 

 posterior angles rounded ; elytra evidently longer than thoi-ax, with three 

 longitudinal series of rather large setigerous punctures on each, the space 

 between being more or less distinctly rugosely striate or punctate, the 

 marginal series consisting of 6-8 punctures, and the other two of 4-6 ; 

 hind body somewhat oblong, not strongly narrowed behind, very sparingly 

 pubescent, and rather strongly and diffusely punctured, with apical por- 

 tion of segments smooth ; legs reddish testaceous, Avith coxse, and 

 sometimes base of posterior femora, darker. L. 4 mm. 



The sexual differences are very slight. 



In moss, &c., in mountainous districts ; very rare ; Scotland, Tay, Dee, and Moray 

 districts (Braemar, Avieniore, Eanuoch (on Grayvel), &c.) ; on the Coutiuent it has 

 been found on the Alps, Pyrenees, Mount Pilatus (Switzerland), &c.
