StaphylinidcB of Japan. 45 



This species is, both in structure and sculpture, allied 

 to P. ni(/ritulus, but it is larger and differently coloured. 

 The moderately long antenna? are black, Avith the two or 

 tlii'ee basal joints yellow ; they are distinctly thickened 

 towards the extremity ; 3rd joint slightly shorter than 

 2nd, joints 6 — 10 transverse. Head Avith the punctuation 

 similar to that of P. nigriiuhis; maxillary palpi much 

 longer and more slender than in nigritulus, their last joint 

 elongate, slender, and very pointed. Thorax narrower than 

 the elytra, longer than broad, nearly straight at the sides, 

 and scarcely at all narrower to the front, its punctures deep 

 and rather large. Elytra slightly longer than the thorax, of 

 a reddish colour, the suture sometimes infuscate, sparingly 

 and not strongly punctured. Hind body broad, rather 

 sparingly punctured, the hind margins of the segments 

 reddish. Legs (including the coxas) yellow, tibia? a little 

 infuscate. The front tarsi quite simple in the male. 



Four specimens. Hiogo. 



86. Philo7ith7is se7-icajis, n. sip. (Sec. 6, Er.) P.micanti 

 affinis. Piceus, antennarum basi pedibusque testaceis, 

 capite orbiculato thoraceque sericeo-micantibus ; elytris 

 crebre punctatis; abdomine confertim punctato, segmen- 

 tonim marginibus posterioribus ferrugineis. Long. 3 lin. 



Mas, tarsis anticis leviter dilatatis. 



Allied to P. micans, but paler in its colour, and with 

 head, thorax and antennte less elongate. The antennre 

 are pitchy or pitchy yellow, with the base paler, 2nd and 

 3rd joints subequal, the penultimate joints quadrate. Head 

 black or pitchy black, a little narrower than the thorax, 

 orbiculate, punctured as in P. micans. Thorax narrower 

 than the elytra, pitchy, or reddish pitchy, a little narrowed 

 to the front, and about as long as broad, its punctures 

 similar to those of micans ; it, as well as the head, has in 

 certain lights a silky reflection caused by a number of 

 extremely fine undulating grooves. Elytra pitchy, a little 

 shining, a little longer than the thorax, finely and rather 

 closely punctured. Hind body densely and finely punc- 

 tured, the hind margins of the segments paler. The legs, 

 including the anterior coxre, are yellow, the middle coxas 

 not contiguous. 



Common at Nagasaki, in garden refuse. 



87. Philonthus amicus, n. sp. (Sec. 6, Er.) P. micanti 

 affinis: Elongatus, niger, thorace piceo, pedibus testaceis.
