Staphylinidce of Japan, 5 



long as broad, the jDenultimate joints distinctly broader 

 than long. Head much narrower than the thorax, dis- 

 tinctly but not closely punctured. Thorax narrower than 

 the elytra, distinctly broader than long, a little narrowed 

 behind, much less depressed and rounded at the front 

 angles than in O. castanea ; it is distinctly punctured, but 

 has no well-defined fovea at the base. The elytra are 

 longer than the thorax, of a brownish colour, darker at the 

 sides (except at the shoulder), rather coarsely punctured. 

 The hind body is shining, and has scarcely any traces of 

 punctuation. 



Three specimens under dead leaves. Copper Temple, 

 Nagasaki. 



6. TJiiasophila rufescens, n. sp. Rufo-ferruginea, sub- 

 opaca, abdomine medio plus minusve infuscato ; prothorace 

 transverso, elytrorum latitudine, angulis anterioribus 

 omnino rotundatis, posterioribus rectis. Long, li lin. 



Allied to inquilina, and about the size of that species ; 

 joints 5 — 7 of the antennee rather less transverse, the 

 thorax rather longer and narrower, and the punctuation 

 rather finer. The smaller size, and different antennae, at 

 once distinguish it from T. angulata. The colour is 

 rather variable, the head, the middle of the antennje, and 

 hind body (except at the apex) being sometimes pitchy- 

 red, sometimes scarcely darker than the other parts. The 

 antennse are short and stout, greatly thickened towards 

 the extremity, the penultimate joints very strongly trans- 

 verse. The thorax is about as Avide as the elytra, the front 

 angles very rounded ; the sides about straight from near 

 the front angles to the hind angles. The elytra are dis- 

 tinctly longer than the thorax, closely and finely punctured. 

 The hind body is finely and rather closely punctured, the 

 extremity always paler than the other parts. 



Three specimens appear to belong to a well-marked 

 variety, being larger and broader, and darker-coloured 

 than the darkest individuals of rufescens. It is possible 

 that the examination of a larger series of specimens might 

 shoAv them to belong to a distinct species. Found with 

 Fo rm ica jap onica. 



7. Homceusa japonica, i\. &\). Picea, nitida, antennis 

 pedibusque rufescentibus, aho testaceo ; thorace latissimo ; 

 elvtris angulo apicali externo fortiter productis. Long. 

 li-Ulin.
