182 CARABID^E. BEMBIDIUM. 



seventh stria being very indistinct, more frequently quite obsolete 

 and the apex entirely smooth, the colour is obscure brassy black 

 or brassy brown, with an oblong testaceous patch on each shoulder 

 and a smaller roundish or oblique one (sometimes connected there- 

 with externally) before the apex ; legs testaceous, femora pitchy 

 at their base. Length 2^ lines. 



This species is distinguishable from the three following by its 

 narrower, more elongate and more convex form. The thorax 

 especially is narrower, less dilated at the sides before the middle, 

 which gives it that narrower appearance ; the colour also is usually 

 brassy black, whereas in concinnum and littorale the brassy green 

 predominates, which is only seen in occasional examples of femo- 

 ratum so distinctly. The elytra are more elongate and the sides 

 more parallel, partaking less of the ovate form than in the next 

 species, being also more finely punctate- striated and having the 

 testaceous spots larger and clearer. 



P. maritimus of the Stephensian collection is represented by 

 examples of this species mixed up with others of littorale. I have 

 examined the single example of P. maritimus in the late 

 Mr. Rudd's collection (now in the Museum of the York Philo- 

 sophical Institution), and find that it is a somewhat aberrant 

 individual of the present species with the thorax rather greener ; 

 I therefore give maritimus as synonymous with B. femoratum. 

 All the examples in the Stephensian cabinet which stand under 

 the name P. concinnus are likewise perfectly identical with this 

 insect ; but the descriptions given by the late Mr. Stephens of 

 P. concinnus, Kirby, as well as the examples standing under that 

 name in the Kirbian collection, correspond with the insect recorded 

 in this work as B. concinnum.

11. B. Bruxellense : viridi-ceneum ; thorace brevi subcordato, 

 basi distincte punctulato ; elytris oblong o-ovatis, fortiter 

 punctato-striatiSj striis externis obsoletis, maculis duabus 

 magnis antennarum basi pedibusque rufo-testaceis, femori- 

 bus obscuris.

Rather larger and considerably darker than the preceding 

 species. Head broader, more coarsely foveated ; antennae brownish 

 black, the basal joint alone entirely and merely the base of some 

 of the following joints red. Thorax usually greener bronze,
