Staphylinida of Japan. 71 



Mas, abdomine segmento V ventrali producto, aplce 

 medio anjriiste profundius excise, 6° margine posteriore 

 late cmarginato, emarginationis margine nigro-setoso. 



Antennss nearly as long as head and thorax, pale yellow, 

 slender, the extremity a little thickened, third joint one 

 and a half times as long as 2nd. Palpi pale yellow, 

 mandibles red. Head very large, broader than the elytra, 

 the eyes large and convex ; it is very coarsely punctured, 

 so that the interstices are only fine reticulations ; in the 

 middle of each puncture is a very fine tubercle. Thorax 

 nan-ower than the elytra, much longer than broad, and 

 much ronnded at the sides ; its sculpture similar to that of 

 the head, but coarser. Elytra about as long as the thorax, 

 coarsely, closely and rugosely punctiired. Hind body a 

 little dilated towards the extremity, rather sparingly punc- 

 tured. Legs white. 



Three specimens, found at Nagasaki by beating trees. 



131. Sunius hisirio, n. sp. Elongatus, niger, sub- 

 o])acus, fortiter punctatus, antennis pedibusque albidis ; 

 capite elytris latiore, illis prothorace paulo longioribus. 

 Long. 3 lin. 



Mas, abdomine segmento 7° ventrali, apice medio, 

 minus profimde triangulariter exciso, 6° simplice. 



This insect so greatly resembles the S. latifrons in 

 every respect, that I could scarcely distinguish it there- 

 from, except by the male characters, which are very dif-

 with the thorax rather broader and more rounded at the 

 sides, the elytra a trifle longer, and also with the joints of 

 the antennte slightly longer. 



Two specimens, 1 ^ , 1 ? . Found in Mitzuyama, 

 Nagasaki. 



132. Sunius hrevipes, n. sp. Fulvo-testaceus, opacus, 

 antennis pedibusque testaceis, abdomine segmentis ultimis 

 duobus nigricantibus ; elytris thorace paulo longioribus. 

 Lono;. li lin. 



Mas, abdomme segmento 7° ventrali, apice medio, 

 anguste triangulariter exciso. 



This species belongs to the himaculatus group, and is 

 the smallest species I know of the group ; at the same 

 time it is rather robustly formed, and has the antenna} and
