ii. Miilc with the femora iiicrassate and the first joint 



of antenna3 simple ; thorax wider B. VALIDUS, ^«J^. 



II. Thorax not or scarcely punctured, at all events 

 behind. 

 i. Male with the first joint of the antennse produced 

 into a small and indistinct tooth on the inner side, 



second joint simple, cylindrical B. BUIBIFEK, /lei'c/i. 



ii. Male with the first joint of the antennse cylindrical, 

 second joint dilated. 



1, Colour dai'k chestnut-brown or reddish ; maxillary 



palpi with the last joint very elongate . . . B. CuRiisii, Leach. 



2. Colour usually pitchy-brown or black, sometimes 



reddish-brown ; last joint of maxillary palpi 

 broad, securiform. 



A. 2nd joint of antennaa in male broader than 



long, securiform ; 1st joint in female one and 



a half times as long as broad B. SECUEIGEE, Reich, 



B. 2nd joint of antenna? in male longer than 



broad, luuulate, 1st joint in female scarcely 



longer than broad B. biteeeli.ii, Denny. 



B. puncticollis, Denny {Areopagus puncticollis, Denny). Colour 

 very variable, entirely chestnut-brown, or reddish, or red with elytra 

 pitchy, or red with elytra and abdomen pitchy ; head narrower than thorax, 

 trianf^ular, with two large fovese between eyes.; antennie ferruginous, rather 

 short and thick, palpi pale with the last joint rather long, dilated inter- 

 nally ; thorax broader than long (in some specimens about as long as 

 broad), broadest before middle, strongly punctured ; elytra and abdomen 

 together short oval, convex, the former longer than together broad, 

 strongly punctured, the latter short ; legs testaceous or reddish, tarsi 

 lighter. L. 1^-H mm. 



Male with the two basal joints of the antenucB thickened, the first 

 armed with a small dentiform appendage on its internal apex, femora 

 simple. 



In moss, dead leaves, &c. ; local but somewhat widely distributed, and in some 

 localities not uncommon ; Loudon district, not common ; Shirley Mickleham, Cater- 

 ham, Croydon ; Hastings; Glanvilles Wootton ; Devon; Midland counties, generally 

 distributed ; common in the Burton-ou-Treut district ; Lincoln, railier common ; 

 Northumberland and Durham districts, not uncommon ; Scotland, Lowlands and 

 Highlands, not rare, Solvvay, Tweed, Forth, Clyde, and Dee districts ; Ireland, 

 Armagh. 



B. validus, Aube. Very like the preceding, but distinguished by the 

 characters of the male, which has the first joint of the antennte slightly 

 shorter and without a dentiform appendage at apex, the femora strongly 

 thickened, and the tibite robust, the posterior pair being of equal breadth 

 throughout ; the thorax is rather broader in proportion than in the pre- 

 ceding species, and the colour, as a rule, is said to be darker, but this is 

 by no means a reliable character, as it is variable. L. 1^ mm. 



Found under the same circumstances as B. puncticollis, and apparently widely 

 distributed, and mixed with that species iu collections ; in Dr. Sharp's collection there
