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



tice sinuato-angustato angulis acutis, fovea basali utrin- 

 que profunda plicaque sat elongata juxta angulum ; 

 elytris passim acute striatis, striis subpunctulatis, punc- 

 tis utrinque majoribus duobus sat conspicuis. Long. 

 4 mm. 



Hakone. 



In the subopalescent surface gloss and dark blue 

 colour similar to B. lisonotum, Bates, but differs from 

 that species in having a thoracic fold or carina near the 

 hind angle. 



The species agrees in many respects with B. atro- 

 cmruleum, Steph., but it is more parallel-sided, and 

 differs in the elytral striae being impressed throughout ; 

 the opalescent gloss is less visible in some examples 

 than in others. 



Bembidium (Peryphus) amaurum. 



B. mruleo, Dej., simile, sed thoracis angulis posticis 

 exstantibus, acutis, elytris grossius punctato-striatis. 

 Oblongo-ovatum, sat convexum, nigro-cseruleum, antennis 

 pedibusque piceo-rufis, palpis pallide rufis ; thorace 

 rotundato-cordato postice sat profunde sinuato-angus- 

 tato, angulis exstantibus, basi sparsim rugoso-punctato, 

 fovea utrinque profundo plicaque acuta prope angulum ; 

 elytris punctato-striatis, stria 7ma paullo minus (sed 

 usque ad apicem) impressa. Long. 5| — 6 mm. 



Hakodate. 



Bembidium Nikkoense. 



B. Normanno, Dej., proxime affine; paullo major, 

 latius ovatum, pedibus runs, etc., nigrum viridi-aeneo 

 tinctum, antennis articulis 1 — 2 et 3 basi pedibusque 

 testaceo-rufis, palpis rufis, articulo penultimo fusco ; 

 sulcis frontalibus simplicibus, parallelis ; thorace fere 

 sicut in B. Normanno anguste cordato, basi grosse punc- 

 tato, fovea utrinque basali lato et profundo, angulis 

 posticis rectis ; elytris paullo latius ovatis, striis modice 

 impressis, 4 — 7 apiceabbreviatis (apice laevissimo) eseteris 

 grosse punctatis, apice concoloribus. Long. 4 mm. 



Nikko. 



Answers in some respects to the description of B. 

 misellum, Harold ; but the form of the thorax is 

 entirely different from that of B. velox and ptisillum, 

 with which the author compares his species.
