Geodephagous Coleoptera of Japan. 217 



Morawitz's specimen was derived, of rather larger size, 

 the pale belts of the elytra are reduced in width and 

 more or less interrupted ; in the other, from Hiogo, rather 

 smaller, the belts are wider (wider than they generally 

 are in European specimens of 0. limbatum). In both 

 the sides of the thorax are straighter and the anterior 

 angles longer than in 0. limbatum. 



Elaphriis dauricus, Morawitz, Bull. Acad. St. Petersburg, 

 1863, p. 239. 



One example at Tomakomai, 17th August, 1880. 



Nebria Lewisi, Bates, Ent. Mo. Mag. xi. p. 22 (1874). 



Kawachi. Abundant under stones at Hakone Lake, 

 and extends north to Morioka ; also at Kumamoto. 



Nebria Sadona. 



Valde elongata, pedibus gracilibus, elytris antice 

 gradatim angustatis sed hurneris distinctis obtusis ; 

 nigerrima subnitida ; capite parvo leevi, collo paullulum 

 constricto ; oculis modice convexis ; thorace fere sicut in 

 N.fasciatopunctata late cordato, angulis posticis retrorsum 

 productis acutis, anticis rotundatis, margine laterali late 

 explanato-reflexo ; elytris profunde striatis, striis fundo 

 subtiliter crenatis, interstitiis convexis tertio 4 — 5 punc- 

 tato. Long. 14 mm., ? . 



Sado. A male example from Oyayama, of similar 

 size and form, differs in the thorax being more gradually 

 narrowed in front and with more produced fore angles. 

 It is possible it may be the other sex of this species. 



Nebria sceviens. 



N. Sadona affinis. Elongata, subgracilis, nigra, par- 

 tibus oris, antennis pedibusque (coxis exceptis) fulvo- 

 rufis ; capite fere kevi, collo convexo nullomodo trans- 

 versim impresso, fronte foveis duabus parum impressis ; 

 oculis valde prominentibus ; thorace relative magno, 

 elytris vix angustiori, quadrato-cordato antice modice, 

 nee rotundato-, angustato angulis anticis productis 

 (apice obtusis), postice longe, sed parum angustato, sub- 

 sinuato, angulis posticis retrorsum productis apice 

 acutissimis, margine laterali explanato-reflexo, limbo
