276 Mr. H. W. Bates' supplement to the 



Very near B. lampros, but much larger and more 

 robust. The basal rim of the elytra forms a sharp 

 angle with the margin at the shoulder, as in B. splen- 

 didum. 



Bembidium (Hydrium) pogonoides. 



B. splendido, Sturm, affine. Oblongum, seneum niti- 

 dum, antennis (articulis basalibus runs exceptis) femori- 

 busque piceis, tibiis et tarsis testaceis, palpis runs 

 articulo penultimo piceo ; thorace quam in B. s2)lendido 

 latiori, late quadrato, paullo ante medium rotundato- 

 dilatato, deinde antice magis quam postice angustato, 

 angulis posticis rectis, basi bistriato plicaque prope 

 angulum ; elytris humeris acutis et acute marginatis 

 punctato-striatis, striis parum impressis 2 — 7 versus 

 apicem vix perspicuis (5ta apice flexuosa et sat profunda 

 excepta). Long. 5f — 6 mm. 



Niigata ; also Eastern Siberia. 



Closely allied to B. splendidum, which, together with 

 many other allied species, belongs to the same section 

 (Hydrium, Lee. olim) as the North-American B. Icevi- 

 gatum, Say. It differs from B. splendidum by its larger 

 size, and by the thorax being much less narrowed 

 behind ; in fact, more narrowed in front and distinctly 

 wider at the base than on the front margin. 



Bembidium ceneipes. 



B. striato, F., multo angustior, thorace subconico, a 

 basi usque ad apicem fere recte angustato. Supra viridi- 

 auratum vix nitidum, medio cuprascens ; antennis palpis 

 pedibusque viridi-seneis ; capite angusto, sulcis frontali- 

 bus longis parallellis, interspatio angusto, convexo ; 

 thorace alutaceo, medio nitido, basi utrinque striola 

 curvata impresso ; elytris angustis, a basi oblique leviter 

 ampliatis, deinde parallelis, apice conjunctim subacute 

 rotundatis, punctato-striatis, striis 6 — 7 prope humeros 

 obliteratis, 8 — 9 sat late separatis sed profundius im- 

 pressis ; interstitiis planis, tertio punctis parvis duobus. 

 Long. 4| — 5£ mm. 



Sapporo ; Chiuzenji. 



Of the species known to me most nearly allied to 

 B. inserticeps, Chaud., but very distinct, and approach- 

 ing B. stenoderum, Bates ; the two marginal strise are
