208 CARABIDjE. BEMBIDIUM. 



rather prominent, disk convex, the dorsal furrow intersected by 

 numerous transverse wavy wrinkles and the entire limb punctured, 

 but the punctures on the sides very minute and sparingly distri- 

 buted, the base with a punctured fovea near each angle. Elytra 

 considerably broader than the thorax, shoulders a little rounded, 

 sides somewhat parallel, oblong, finely punctate-striated till 

 beyond the middle, when the punctured striae disappear, the 

 third interstice with two deep impressions ; underside of the 

 body and legs dark bronze ; sides of the thorax punctured. 

 Length 2 lines. 



Abundant on the gravelly beaches of rivers in the north of 

 England, in Wales, Scotland and Ireland; as well as in the London 

 district and in many other parts of the kingdom. My friend 

 G. Guyon, Esq., has found it in plenty on the shores of the 

 Thames near Richmond.

Brownish brassy or occasionally blue-black, variable in colour. 

 Head thickly punctured, with an oblong fovea on each side; 

 antennae longer than in the preceding species and more slender, 

 brownish black with the basal joint red. Thorax cordate, much 

 contracted behind, convex, punctured throughout, but most 

 closely in front and at the base. Elytra oblong, broad, sides 

 almost parallel, apex rounded, disk convex, deeply punctate- 

 striated, the punctures very evident, and the striae continued to 

 the apex, before which however the third and fourth, as well as 

 the fifth and sixth unite in pairs, the third interstice has two 

 deeper impressions ; underside black, blue-black, or bronzed, with 

 some punctuation on the thorax and breast ; legs, testaceous red, 

 tibiae with a greenish or bluish metallic tinge. Length 2^ lines. 



This insect is the Carabus velox of the Fauna Suecica, and I 

 have accordingly restored the name.
