158 CARABID^E. STENOLOPHUS. 



the name dorsalis, but the Fabrician description of the latter insect 

 can refer only to the species to which we have given that name. 

 It is very local: "Battersea fields and Old Brompton, spa- 

 ringly," Mr. Waterhouse. " Taken rather plentifully in a gravel- 

 pit near Windsor," Mr. Griesbach (as quoted by Mr. Stephens). 

 In May 1849, I procured a fine series on the banks of a stream 

 in Herringstone marsh near Dorchester. 



6. S. dorsalis : oblongus, rufo-testaceus ; thorace subquadrato, 

 postice utrinque foveolato, angulis posticis subrotundatis, 

 disco plerumque fusco ; elytris striatis, plaga oblonga 

 posteriore nigra ; antennarum basi pedibusque testaceis.

Oblong, rather wide. Head black, smooth and shining, with 

 two obsolete fovese in front, external edge of the mandibles, base 

 and apex of the palpi and basal joint of the antennae testaceous, 

 penultimate joint of the palpi and rest of the antennae pitchy. 

 Thorax reddish testaceous with a dusky patch in the centre of 

 the disk, sometimes almost or quite covering it and leaving the 

 edges only pale and sometimes almost obsolete, subquadrate, the 

 breadth greater than the length, sides slightly rounded, posterior 

 angles somewhat rounded, disk rather flattish, with a fine dorsal 

 furrow and an impressed fovea at the base close to each angle. 

 Elytra oblong, broad, sides almost straight, finely striated, in- 

 terstices flat, testaceous, with a blue-black oblong patch behind, 

 in some examples interrupted at the suture, in others covering the 

 entire disk except the shoulders, in others again more or less 

 obsolete ; body beneath black, legs pitchy or pale testaceous.

This insect, which somewhat resembles meridianus, cannot be 

 confounded with it. It is much broader ; the thorax especially 

 is shorter and broader, and not like that of meridianus distinctly 

 narrowed behind, and is always more or less rufous with a dusky 

 patch in the middle. Stephens has given as its localities, "Wands- 

 worth Common and Copenhagen Fields at the roots of grass on 

 gravelly banks by the sides of ponds;" and " marshes near Faken- 

 ham." I am indebted to Mr. Hadfield for a fine series of varieties, 

 which he procured from a gravel-pit on Stapleford Common near
