Geodephagous Coleoptera of Japan. 261 



Colpodes limodromoides. 



Anchomeno (Limodromo) similis ; valde elongatus, 

 parallelogrammicus, piceo-niger nitidus, antennis palpis, 

 thoracis margine laterali pedibusque castaneo-rufis, cor- 

 pore subtus plus minusve castaneo ; capite mox pone 

 oculos valde prominentes angustato ; thorace laevi, quad- 

 rato, paullo ante medium modice dilatato, deinde postice 

 leviter sinuatim angustato, angulis posticis obtusis sed 

 distinctis, margine laterali sat late explanato-reflexo ; 

 elytris prope apicem oblique sinuatis, apud suturam pro- 

 duces breviter truncatis, angulo suturali breviter dentato, 

 dorso punctulato-striatis, interstitiis subconvexis. Meta- 

 thoracis episterna elongata et angustata. Pedes elon- 

 gati robusti ; tarsi posteriores utrinque sulcati, articulo 

 4to omnibus emarginato. Long. 15 mm. 



All the large islands, and in Sado. Has the habits 

 of Anchomenus livens, and is rare. 



As C. amphinomus and numerous similar species look 

 like Agona, with tarsi modified in the sense of Colpodes, 

 so this species may be looked upon as a Limodromus or 

 a Batenus, Motsch., with similar modification. If this 

 be truly the case, Colpodes is an artificial genus, com- 

 posed of species of different generic groups, all having 

 the tarsi more or less adapted for climbing up stems of 

 plants or on foliage.

Elongatus, subdepressus, piceo-niger nitidus, elytris 

 olivaceo-seneis, antennis, palpis thoracis margine laterali

 palporum articulo terminali fusiformi (apice attenuato) ; 

 thorace subcordato, antice usque ultra medium sat late 

 rotundato, postice sinuato-angustato, angulis posticis 

 parum obtusis, anticis valde rotundatis, margine laterali 

 explanato-reflexo anguste castaneo-rufo, dorso trans- 

 versim strigoso, foveis latis basalibus punctatis ; elytris

 apud suturam subproductis rotundatis, punctulato- 

 striatis interstitiis planis, tertiotripunctato. Metathoracis
