Geodephagous Coleoptera of Japan. 257 



Anchomenus leucopus, Bates. 



Bates, Trans. Ent. Soc. Lond., 1873, p. 279. 



Niigata, Awomori, and Shimonosuwa are additional 

 localities for this elegant species,* which belongs to the 

 same group as A. cyaneus, calleides, &c. The prosternum 

 and metasternum are rather strongly punctured. 



Anchomenus (Agonum) scidptipes. 



A. mcesto proxime affinis et similis, sed major praecipue 

 magis elongatus ; toto niger, palpis apice runs ; capite 

 ovato oculis parum prominentibus ; thorace sicut in A. 

 mcesto sed longiori, subcirculari, postice perparum angus- 

 tato, margine laterali postice et basali (utrinque) elevato ; 

 elytris elongato-oblongo-ovatis, apice distincte sinuatis, 

 striatis, striis parum conspicue punctulatis, interstitiis 

 subconvexis, tertio tripunctato ; tarsis posterioribus opacis 

 late sulcatis, supra medio angustissime unicarinatis. 

 Long. 8 — 10^ mm., S , ? . 



Junsai Lake, Hakodate ; rare. 



The side grooves of the four posterior tarsi are re- 

 markably broad, and opaque with minute sculpture, 

 leaving a narrow and sharp dorsal carina alone polished. 

 A similar form is found in Eastern Siberia, apparently 

 undescribed, in which the thorax is shorter (a little 

 longer only than in A. mcestus), and the tarsal carinse 

 less narrow. 



Anchomenus (Agonum) suavissimus. 

 A. gracili (Gyll.) proxime affinis; duplo major; gra- 

 cilis, niger politissimus, elytris subopalescentibus ; capite 

 ovato ; thorace ovato, quam longitudine vix latiori, lateri- 

 bus sequaliter arcuatis, angulis anticis sat valde productis, 

 posticis omnino rotundatis, fovea utrinque basali lata, 

 lsevi, medio lineola impressa ; elytris elongato-oblongo- 

 ovatis, apice sat sinuatis, plica basali antrorsum ob- 

 liquata, dorso subtiliter sed acute punctulato-striatis, 

 interstitiis planissimis, tertii punctis 2 et 3 in medio 

 interstitio sitis ; tarsis tenuibus, 4 posticis nitidis utrinque 

 late sulcatis. Long. 9 mm., $ , ? . 



Ogura Lake, Honjo, Tokio. Among reeds in marshes.
