Geodephagous Coleoptera of Japan. 285 



Demetrias marginieollis. 



D. atricapillo longior, prsecipue capite et thorace rnagis 

 elongatis, illo post oculos prolongato perparum rotun- 

 clato, hoc ante basin vix sinuato angulis posticis obtusis ; 

 flavo-testaceus, capite nigro epistomate partibusque oris 

 rufis, thoracis marginibus lateralibus anguste nigro- 

 fuscis, elytrorum sutura fusca ; capite impunctato ; ely- 

 tris punctulato-striatis, striis versus latera rninime im- 

 pressis. Long. 5| mm. 



Miyanoshita, Honjo, and Nowata. 



In the elongate head and thorax agrees with D. Amur- 

 ensis, Motsch. (= siHricus, Mor. ?) and D. longicollis, 

 Chaud., from Eastern Siberia. But in the description of 

 neither is any mention made of the fine brown margins 

 of the thorax, which distinguishes the Japanese form ; 

 from D. longicollis besides, of which I possess a speci- 

 men, it differs in many points. The dusky streak 

 along the suture covers one interstice near the base and 

 widens to two interstices from the middle to near the 

 apex. 



Lachnoderma asperum. (PI. XIII., fig. 2). 



Oblongum dense erecte pubescens, nigrum nitidum, 

 elytris, unguibus, abdominisque apice castaneo-rufis ; 

 capite grosse punctato medio sublsevi ; oculis valde 

 prominentibus ; thorace lato et brevi, basi lobato, antice 

 explanato-dilatato, rotundato, medio angulato, deindepos- 

 tice valde sinuato-angustato, angulis posticis productis 

 acutis, limbo toto grosse scabroso-punctato, disco lsevi ; 

 elytris striato-punctatis, punctis profundissimis, inter- 

 stitiis sparsim punctulatis, apice transversim truncatis, 

 angulis exterioribus valde rotundatis ; tarsis supra pube- 

 scentibus, articulo 4to bilobato ; unguibus basi dilatatis 

 et longe pectinatis. Long. 8 mm. 



Above Miyanoshita. One example under a stone ; 

 another, partly eaten, in an ant's nest ; May 3rd, 1880. 



I refer this curious species to the genus Lachnoderma, 

 instituted by W. Macleay for an Australian species in 

 Trans. Ent. Soc, N. S. W., vol. ii., p. 321. Singilis 

 hirsutus, Bates, Trans. Ent. Soc. Lond., 1873, p. 333, 

 from Hong-Kong, is another species of the same genus. 

 Chaudoir referred Lachnoderma to his subgroup Physo- 

 derides.
