New Species of Staphylinidae from Singapore. 241 



Mimocyptus, 11. gen. 



.Minnie, strongly convex, contractile, in facies very similar to 

 Hypocypttis. Head transverse, deeply inserted in the thorax. 

 Antennae II -jointed. Mandibles short and stout, obscurely serrate 

 towards the apex of their inner margin. Inner lobe of the maxilla 

 narrow, with pectinate inner margin; outer lobe broad, obtriangular, 

 furnished with long setae on the distal margin. Maxillary palpi 

 with tlie 1st joint very small, the 2nd curved, much larger and stouter, 

 the 3rd a little longer than the 2nd, enlarged towards the apex, the 

 4th as long as, but narrower than the .'3rd, conical. Mentum (pars 

 antica) transverse, quadrangular, narrower at the anterior than at 

 the posterior border, which are both truncate. Labium transverse, 

 narrower in front, quadrate. Labial palpi 3-jointed, the 1st joint 

 short and stout, broader than long, the 2nd smaller and shorter than 

 the 1st, broader than long, the 3rd much narrower than the preceding, 

 as long as the first two joints together, almost cylindrical. Tongue 

 broad, membranous, rounded, deeply and triangularly emarginate 

 in front, almost bilobed. Paraglossae distinct, pectinate, extending 

 slightly beyond the anterior margin of the tongue. Thorax strongly 

 transverse, convex, overlapping the elytra when the insect is ex- 

 tended ; the anterior margin broadly emarginate, the sides strongly 

 rounded, passing insensibly into the base, the anterior angles obtusely 

 rounded. Presternum small, the episterna much abbreviated, the 

 epimera free, elongate as in Tach in us. Anterior coxae contiguous, as 

 long as and larger than the femora. Mesosternum broadly and deeply 

 emarginate in front ; the middle coxal cavities completely separated 

 by a very narrow mesosternal process. Metasternum bisinuate at 

 the posterior margin, the posterior coxae contiguous. Elytra extend- 

 ing beyond the metasternum, finely bordered at the sides ; the 

 epipleura incomplete and quite invisible when viewed from the side. 

 Tibiae setose. Tarsi all 5-jointed ; the anterior pair with the first 

 four joints short, triangular, emarginate at the distal margins, the 

 4th joint smaller than the preceding; the middle pair with the 1st 

 joint elongate as long as the two following joints together, the 2nd 

 and 3rd of equal length, each a little longer than broad, the 4th 

 smaller than the 3rd, the 5th elongate, nearly as long as the three 

 preceding together; the posterior pair similarly formed to the inter- 

 mediate; the claws all simple. Abdomen short, conical, retractile. 

 narrowly margined. 



58. Mimocyplus globulus, n. sp. 



Strongly convex, shining, ferruginous red, the fore-parts impunc- 

 tate, the abdomen scarcely perceptibly punctured, very finely and
