190 CARABID^E. BEMBIDIUM. 



This species is more local and less abundant than many of its 

 allies, and from its habit of remaining concealed in crevices of 

 banks and old stumps, apt to be overlooked. It is found in the 

 north of England and in Scotland. " Banks of the Tyne and in 

 the gravel of a rivulet in a dene above Winlaton Mill." Messrs. 

 Hardy and Bold. It is also found in willow stumps near Burton- 

 on -Trent ; and in July 1852 I captured a fine series by the side 

 of the Dee, at Llangollen, by digging them out of a clayey 

 bank.

Above shining metallic green, sometimes bluish. Head (PL II. 

 f. 15) short and triangular, narrowed in front so as to render 

 the eyes rather prominent ; base of the palpi and two or three 

 joints at the base of the antennae testaceous, the remainder, 

 together with the penultimate joint of the palpi, pitchy brown. 

 Thorax short, subcordate, much broader than in monticulum, 

 sides moderately rounded in front and a little narrowed behind, but 

 rather abruptly so, posterior angles right angles, the dorsal furrow 

 transversely wrinkled and terminating before in an evident im- 

 pression strongly marked, the base much depressed and rather 

 coarsely punctured, the basal fovese large and deep. Elytra 

 oblong-ovate, convex, deeply punctate-striated, the striae entire 

 on the sides (but the punctuation finer) and carried nearly if not 

 quite to the apex, before which however the punctures disappear, 

 the third interstice with two impressions; underside brassy 

 black, the apex of the elytra sometimes rusty red, legs testaceous, 

 with the thighs more or less pitchy black at the base, sometimes 

 wholly testaceous. Length 2^ lines.
