the Staphylinidse of Japan. 293 



basal joint fuscous, the others black ; fourth to tenth joints 

 slightly transverse. Head black, shining, impunctate, almost 

 without pubescence. Thorax about as broad as the elytra, 

 not twice as broad as long, rounded at the sides, very slightly 

 narrowed in front, very delicately punctulate, shining, on 

 the middle with a very large depression, not extending quite 

 to the front. Elytra a little longer than the thorax, sordid 

 testaceous, blackish at the base, very finely punctate. Hind 

 body with all the segments finely, moderately closely punc- 

 tate. 



Nagasaki, 22nd February, 1881 ; two examples. 



This may be placed near the European H. nigra^ to which 

 it is not, however, at all closely allied ; if the remarkable 

 thoracic depression be sexual, the two examples are no doubt 

 males, but there is no peculiar structure of the hind body to 

 indicate this. 



Homalota lutulenta, n. sp. 



Parva, rufula, autennarum basi, thorace, elytris pedibusque testa- 

 ceis ; antennis extrorsum, capite abdomiueque ante apicem fusces- 

 centibus ; crebre punctata, abdomiae fortiter acuniinato, crebrius 

 conspicueque setosello. 



Long. 2| millim. 



Antennas short and rather stout, thicker externally, third 

 joint rather shorter than the second, fifth to tenth joints trans- 

 verse, the last of them rather strongly so ; terminal joint 

 about as long as the two preceding together. Thorax con- 

 vex, rounded at the sides and base, and narrowed in front, 

 bright yellowish red, finely punctate, rather feebly transverse. 

 Elytra slightly longer than the thorax, coloured like it, rather 

 more closely punctate. Hind body very acuminate, rather 

 closely punctate, evidently pubescent, and with the exserted 

 setai very distinct. 



Yokohama and Nagasaki. 



This is one of the species with most strongly acuminate 

 hind body ; it may be easily distinguished from the equally 

 bright-coloured H. vivida by its smaller size, thicker an- 

 tennae, and more closely punctate hind body. 



Homalota oUgotinula, n. sp. 



Parva, brevis, subdepressa, testaceo-ferruginea, pedibus flavis ; sub- 



tilissime punctulato ; antennis brevibus, crassis. 

 Long. 2 millim. 



Antennae stout, very short, thicker externally ; fourth to
