CARAB1D.E. BEMBIDIUM. 197 



ought to be referred, that name having been successively applied 

 to B. femoratum, articulatum and littorale, but rejected on the 

 ground that Linna3us states the legs to be black. In the Linnsean 

 collection we find a mutilated individual of the species before us 

 (B. fumigatum, Dej.), and I have accordingly ventured to restore 

 the name as originally asserted by Paykull (C. ustulatus var. S. 

 = C. rupestris, L.). LinnaBus probably described his insect from 

 an example with unusually dark legs. 



The species, which appears very distinct, is extremely rare in 

 Britain. The only indigenous examples I have seen are in the 

 Stephensian cabinet and are stated to have been found at 

 Swansea. 



29. B. fumigatum : nigro-aneum ; thorace subcordato, postice 



subangustato, angulis posticis rectis ; elytris oblongo- 

 ovatis, testaceo-variegatis, fortiter punctato-striatis ; an- 

 tennis basi pedibusque rufo-testaceis.

About the size of the preceding species, but narrower in front. 

 Head and thorax obscure greenish bronze, tip of mandibles and 

 two joints at the base of the antennae testaceous red, the rest of 

 the antennae and palpi obscure. Thorax (PI. II. f. 12) subcor- 

 date, sides more rounded and dilated about the middle, then 

 contracted, but just before the angles sensibly straight, so as to 

 form with the base a right angle, disk moderately convex, the 

 dorsal and transverse lines well defined, the base with two fovese. 

 Elytra oblong-ovate, deeply punctate-striate on the disk, the 

 sides and apex smooth, the first stria nearest the suture entire, 

 the next rather abbreviated, all the others still more so, the 

 colour varies from testaceous spotted or banded with fuscous or 

 bronzed black, or the latter predominates and is more or less 

 variegated with testaceous, very much after the manner of flam- 

 mulatum; the underside is bronzed black, the legs are testaceous 

 red. Length IJ-2 lines. 



Abundant in marshy places, but rather local : Hammersmith 

 marshes ; the fens of Essex and Lincolnshire, &c. 



30. B. ephippium : capite thoraceque viridi-aneis, nitidis ; 



thorace subcordato } postice coarctato, angulis posticis rec-
