Bemhidmm.] adephaga. 109 



in front of the eyes ; thorax short and broad, rather convex, ■witli 

 sides rounded from below the anterior angles to behind middle, and 

 thence contracted, posterior angles right angles, dorsal furrow distinct, 

 l)asal fovefe broad and rather deep ; elytra oval, rather convex, with 

 rather strongly punctured strire, which are carried (at all events the 

 inner ones) nearly to apex ; legs reddish-yellow, femora (at least on the 

 under side) pitchy. L. 2^ mm. 



A northern species; first taken by Messrs. Bold and Murray on the banks of the 

 Irthing, Cuniberhmd, and afterwards in other localities in the district amongst grass 

 on the margins of streams ; in Scotland it is local in the Tweed, Solway, and Forth 

 districts, and sometimes is found not uncommonly where it occurs. 



This species comes nearest to B. gilv/'pes, but is distinguislied by its 

 broader thorax, which is less narrowed behind, by the darker femora, 

 and especially the evidently less strong punctuation of the elytra. 



B. g-ilvipes, Sturm {Mannerheimi, Dej., nee, Sahib.). Black, 

 shining ; rather smaller than the preceding ; antennce blackish with base 

 red ; thorax convex, more narrowed behind than in Sdii'q^X'di, but 

 otherwise much the same as in that species ; elytra ovate, very convex, 

 with sides evenly rounded, with very strongly punctured striae, becoming 

 much finer towards sides, and evanescent at apex (except one or two 

 inner ones) ; legs entirely reddish testaceous : the very strong sculpture 

 of the disc of the elytra is the best distinguishing mark of this species. 

 L. 2-2i mm. 



Sandy and gravelly places on banks of rivers; often found in numbers in flood 

 refuse. Local, but widely ilistributed throughout England; it occurs in the Nortli- 

 umberland and Durham district, but the only Scotch record, " Kaehills, Kev. W. 

 Little," appears somewhat doubtful. 



B. laxapros, TIcrbst. Brassy, very shining, rarely bluish or blackisli ; 

 head witli two deep parallel impiessions between eyes ; antenn;e black 

 with tlie first joint (and sometimes the second) red, at all events be- 

 niiatli ; thorax with sides rounded in front and very strongly contracted 

 behind, posterior angles riglit angles, sharp and somewhat projecting, 

 dorsal furrow distinct, base with a deep furrow on each side, the space 

 between punctured ; elytra long oval, narrowed and rounded at shoulders, 

 Avith six punctured striie distinctly marked, apex and sides smooth, 

 or almost smooth; legs reddish brown or reddish, tibiae paler. L. 2A- 

 3^ mm. 



Common and widely distributed throughout the kiugilom ; also over all Europe, 

 and a great portion of Asia. 



The V. vclox (B. 14-striatum, Tliunif.) is ratlier larger and has seven 

 rows of punctures instead of six as in the type form ; it is usually 

 darker and duller, but is often coloured like the type ; it is the B. 

 relax of Erichson, and might perhaps be regarded as a separate species 

 witli as much right as B. riparium ; it occurs not uncommonly with tho 

 type in England and Scotland, and probably in Ireland.
