Staphylinidce of Jaj^an. 93 



Tliorax transv^erse, about as broad as the elytra, a little 

 narrowed behind, of a sliining-reddish colour like the 

 head, distinctly trisulcate, the lines bounding the middle 

 groove broad and flat ; it is distinctly punctate-strigose at 

 the sides, the sculpture on the middle parts very scantv. 

 Elytra longer than the thorax, of a shining-yellowish 

 colour, sparingly but rather distinctly strigose. The 

 breast is blackish, except that the metasternum at the 

 extremity is red in the middle. The legs are ])ale yellow, 

 the anterior tibiae slender, only slightly constricted before 

 the extremitv. 



In the male there is, on the underside of the 7th seg- 

 ment of the hind body, a small fovea, placed quite at tlie 

 extremity; the sides of this fovea are a little elevated, and 

 project a little beyond the hind margin. 



A single specimen ; found at Hiogo. 



170. Oxytchis opacifro7is, n. sp. Testaceus, subopacus, 

 capite fere toto nigro, fronte medio lineola impressa ; thorace 

 anguste nigro-marginato, elytris dense subtiliter strigosis, 

 sutura nigricante. Long. 2| lin. 



Closely allied to O. nigriceps, Kraatz, but differing as 

 follows : O. opacifrons is not shining, the head is quite 

 opaque and very obsolctely punctured ; the lines of the 

 thorax are less elevated, and the elytra much more densely 

 and finely sculptured. The antenna are yellow, 5th joint 

 larger than 4th, and 6th than 5th ; joints 6 — 10 distinctly 

 transverse, and differing little from one another. Head 

 narrower than the thorax, dull black, the elevations over 

 the antennas reddish ; it is almost impunctate, and has a 

 small fovea or short indistinct channel at the back in the 

 middle. Thorax yellowish, narrowly margined with black, 

 with four indistinct longitudinal elevations ; the middle 

 ones entire, the lateral ones abbreviated ; it is indistinctly 

 strigose, the elevated parts slightly shining. Elytra 

 yellowish, with the suture black, finely and indistinctly 

 strigose. Hind body dull yellowish, scarcely punctured. 

 Legs pale yellow. 



Abundant in dung.
