60 COLEOPTERA. 



Not uncommon in many places round London, frequently 

 associated with its near allies, B. verbasci, Duft., and B.

 2. Bembidium NiGRicoRNis ? Gyll. ; Waterhouse, Proc. 

 Ent. Soc. 6 Feb. 1860, Zool. 6936 (1860). 



The Bembidium nigricornej Gyll. [Ins. Suec. iv. 402, 

 5 — 6 (1827) ], hitherto known as an inhabitant of high 

 northern European latitudes alone, has been carefully de- 

 scribed not only by Gyllenhal, but by Dejean, Sahlberg, 

 Zetterstedt, Schiodte and Duval, and the points in' which it 

 differs from its near ally, B. lampros, Hbst., distinctly 

 pointed out by these authors. Unfortunately I do not 

 possess either an indigenous or foreign example of this spe- 

 cies ; the following translation, however, of the description 

 given by M. Jacquelin-Duval in his justly celebrated mono- 

 graph of the European Bembidiidae, '' De Bembidiis Euro- 

 paeis," published in the ninth and tenth volumes of the second 

 series of the " Annales de la Societe Entoraologique de 

 France," may perhaps be acceptable to some of our Coleop- 

 terists. 



'^ Above brassy. Palpi brown. Antennae entirely black, 

 their first joint slightly brassy. Frontal sulci less marked 

 than in B. lamproSj the interval which separates them wider, 

 w ith two slight short ridges posteriorly near the eyes. Pro- 

 thorax of very peculiar form, wide, very short, very little 

 constricted behind, appearing almost rounded in the middle 

 at the sides, as in group 14 ; * transver.--e impressions but 

 little marked, central longitudinal line slight, base nearly 

 straightly trunctate, presenting above a few small punctures 

 or rugosities, fovea? at the posterior angles round and deep, a 

 little shorter than in lampros, posterior angles obtuse and 

 but slightly salient ; elytra as in the preceding {lampros) not 



* Philochthus and Ocys of English collections.
