. BEMBIDIUM. 189 



rounded, sides also rounded and rather widest behind the middle, 

 disk very convex, deeply punctate-striated, the punctured striae 

 becoming fainter as they approach the extremity, the apex being 

 quite smooth, but the outer strise not effaced till behind the 

 middle, and the eighth is continued nearly to the tip, before 

 which it assumes the form of a deeply impressed groove, the 

 third interstice has two impressions close to the third stria ; in 

 some examples there is an obscure blood-red spot on the wing- 

 cases near the suture behind ; underside greenish bronze, apex 

 of the abdomen sometimes testaceous ; legs testaceous. Length 

 21 lines. 



M. Jacquelin-Duval considers this insect an extreme variety 

 of Elaphrus rufipes, 111., of which species no typical example has 

 occurred in Britain, if indeed the latter be distinct from B. rufi- 

 pes, GylL, Dej. It is readily distinguished by its very convex 

 form and its similarity to the insect from which its specific name 

 is derived (Stomis pumicatus) ; it is now introduced for the first 

 time into the British fauna, having been discovered by Mr. Bold, 

 of Newcastle, on a sandy bank of the river between Lanercost 

 Abbey and Naworth Castle, Cumberland, in the month of June 

 1848, but it is apparently very scarce. 



20. B. monticulum : viridi-ceneum ; thorace cordato, postice vix 

 punctulato ; elytris oblong o-ovatis, convexiusculis, punc- 

 tato-striatiSj striis externis obsoletis, viridi-cyaneis ; antennis 

 basi pedibusque testaceis.

Brassy green, palpi and antennae brownish, with the base 

 testaceous. Thorax rather small, cordate, sides very little 

 rounded before the middle, narrowed behind, posterior angles 

 rather acute, base depressed, sometimes finely strigose between 

 the two fovese, but not distinctly punctured and sometimes 

 indeed nearly smooth, the dorsal furrow well impressed, the 

 disk finely wrinkled and moderately convex. Elytra oblong- 

 ovate, much broader than the thorax, sides moderately and 

 regularly rounded, convex, deeply punctate-striated next the 

 suture, more finely so externally and the outside stria obsolete, 

 leaving the sides as well as the apex smooth, the colour is 

 greenish black with a cyaneous reflection; the underside bronzed 

 black ; the legs pale testaceous. Length 21 lines.
