Longicoru Coleoptera of Japan. 381 



ad elytrorum ba.sin depreasum, crebre punctatum, opacum. Caput 

 exsertum, rotundatuni, convexum, obtusum, postice crassum, fronte 

 convexa, genis modice clongatis ; tuberibus antenuiferis vix ele- 

 vatis, condyle antennarum exserto. Labrum parvura. Falpi 

 parvi, apice obtusi. OcuU vix conspicui, divisi, lobo superiore 

 parvo. Antennce corpore longiores, filiformes, robusti ; sparsim 

 longe pubeseentes ; scapo modice elongato subcylindrico, cajteris 

 articulis regularibus. Thorax breviter cylindricus, inermis, cou- 

 vexus, postice depressus. Elytra postice paululum ampliata, 

 apice obtuse rotundata. Pedes breves ; tibiae intermedioe extas 

 sulcatse ; ungues divergentes, simplices, Acetahula antica postice 

 clausa. Pro- et mesosterna inter coxas angusta, longitudinaliter 

 convexa. Acetahula intermedia extus aperta ; sed epimera meso- 

 thoracica baud conspicua. Metatliorax ut in subfam. Dorcadiinis 

 brevis, 



Tlie affinities of this curious genus are a difficult problem. 

 According to the technical characters employed by Lacordaire, 

 it would belong to the Ap)omecynin(:e, except perhaps for the 

 short metathorax. There is much, both in facies and form of 

 the sterna, which reminds one of the Australian genus MesoUta 

 in the Parmenince group ; but the claws are not divaricate, the 

 middle tibise have a conspicuous exterior groove, and the an- 

 tennse are thick to the apex. The sides of the sternum are so 

 thickly punctured that the sutures are invisible; and it is 

 doubtful whether the mesothoracic epimera penetrate to the 

 sockets, which are apparently open. 



Microlera ptino'ides^ n. sp. 



M. atro-fusca, opaca, toto corpore (abdomine excepto) grosse punc- 

 tato ; elytris basi rufescentibus, vitta utrinque subbasali abbre- 

 viate fasciaque pone medium cinereis ; an tennis piceo-rufis, 

 nitidis; pedibus piceis, ciuereo-pubescentibus. Long. l|-l|lin. 



Hiogo ; on dead branches of jiEgle sepiaria. 



The body, viewed in profile, has a double convexity, or may 

 be termed biarcuate ; the front is a little inclined backwards 

 towards the prosternum, and forms, with the vertex and 

 thorax, a regular convexity ; the hind part of the thorax and 

 base of the elytra are depressed, and the rest of the elytra is 

 convex. The elytra at the base are very little broader than 

 the base of the thorax (which is a little constricted) ; tlie 

 shoulders form right angles, and there is a short obtuse lateral 

 ridge proceeding from them, causing the sides of the elytra to 

 be nearly vertical almost to the apex. 



Atimura japonica, n. sp. 



A. fusco-grisea, capite apice(iue elytrorum plus minusve t'ulvis;
