Iwakisan, abundant. 



Appears to differ from all the numerous Siberian species 

 of the Gyllenhalii group which have been described. N. 

 prote?isa, Mots, (anthracina, Morawitz) seems to approach 

 it most nearly, but, besides being smaller, it differs in 

 the sculpture of the head and elytra. 



Nebria chalceola. 



Parva, convexiuscula, piceo-nigra elytris obscure 

 viridi-asneis, antennis palpis tibiis et tarsia rufo-piceis ; 

 capite lsevi postice transversim impresso ; oculis magnis 

 convexis ; thorace relative magno, quadrato, postice 

 minime angustato, ante medium leviter rotundato, angulis 

 anticis parum productis posticis rectis, margine laterali 

 late explanato-reflexo interdum rufescenti, supra (punctis 

 nonnulis basi exceptis) kevi, polito, foveisque profunde 

 impressis ; elytris brevius oblongo-ovatis, striis punctato- 

 crenatis versus latera et apicem evanescentibus, plica 

 basali recta transversa, angulo humerali dentiformi ; 

 corpore subtus laevissimo ; processu mesosternali minus 

 elevato, supra declivi. Long. 6| — 7 mm., $ , ? . 



Hakone, Oyama, Niohozan. 



A very distinct species. At first sight resembling a 

 small PterosticJiid much more than a Nebria. It is 

 less slender in all its parts than other Nebria, and the 

 antennae are distinctly shorter. The elytra are dark 

 bluish green, metallic. 



Nebria Snowi. 

 N. Germari subsimilis, sed oculis magis prominulis 

 elytrisque versus basin minus angustatis, &c. Nigro- 

 picea elytris leviter purpurascentibus antennis palpis 

 pedibusque obscure piceis his interdum rufo-piceis ; 

 capite laevi postice (medio collo) fovea lineari impresso ;
