Bembidium nitidulum, var. C., Jacq.-Duv. Ann. Soc. Ent. 9.560 



Above green, very slightly brassy, shining, considerably larger 

 than nitidulum. Head more oblong and flatter, broader in front, 

 so that the eyes do not appear at all prominent (PI. II. f. 14), 

 palpi and three joints at the base of the antennae testaceous, the 

 rest of the antennae brownish and all the joints longer than in 

 nitidulum. Thorax sensibly less short, the sides less dilated in 

 front and less abruptly narrowed behind, the base very slightly 

 or altogether obsoletely punctulated. Elytra broad, more rounded 

 on the sides, strongly striated on the disk, but the punctuation 

 finer and entirely effaced at the extremity, at some distance from 

 which there is frequently an obscure red blotch common to both 

 wing-cases and extending quite across them ; legs entirely testa- 

 ceous red. Length 2J lines. 



M. Jacquelin-Duval has considered this insect a variety of the 

 preceding, but as I have never been able to unite them satisfac- 

 torily by intermediate links, I have retained it under the name 

 affine, to which it is fully entitled, because the name rufipes, 111., 

 is applicable to a different species, whilst rufipes, Gyll., is identical 

 with nitidulum. The examples of Peryphus qffinis in the late 

 Mr. Rudd's collection which I have examined, perfectly accord 

 with the present species. They were captured by him near 

 Marton, Yorkshire ; and the insect is widely distributed though 

 somewhat local, in gravel-pits near London, Woking, Isle of 

 Wight, Northampton, North Wales, &c.
