New Species of Staphylinidac from Singapore. 233 



and elongate, tlie inner margin of tlie apical third furnished with 

 short strong teeth, the middle third set with longer pectinations; 

 outer lobe membranous, triangular, the apex ciliatc. The tongue 

 narrow, elongate, a little narrower at the base and slightly widened 

 and rounded at the apex, about half as long as the first joint of the 

 labial palpi. Paraglossae distinct ciliate. Labial palpi 2-jointed, 

 the suture between the joints indistinct, styliform, the 1st joint 

 elongate, the 2nd fully as long as the 1st. Gular sutures distant, 

 diverging iiosteriorly. The temples bordered beloAV. Prosternum 

 pointed behind. Mesostcrnal process narrowed and rounded 

 posteriorly, the intermediate coxae moderately distant. Meta- 

 sternal process truncate. Tarsal formula 4, 4, 5; the anterior 

 tarsi with the first three joints rather short and subequal, the 4th 

 as long as the three preceding together; the middle tarsi with the 

 first three joints moderately short (but longer than those of the 

 anterior pair), subequal, the 4th as long as the three preceding 

 together and furnished with an appendage near the apex; the 

 posterior with the first four joints elongate, gradually decreasing 

 in length, the 5th nearly as long as the two preceding together 

 and with an appendage near the apex. Tibiae ciliate. Elytra 

 distinctly sinuate internal to the posteroexternal angle. 



I found this genus on Sihisn eeyloniea Kr., a species 

 occurring in Singapore in rotting fruit. The facies is very 

 different to that of the European species of Silusa, and 

 much more nearly approaches that of Gyrophaena, the 

 thorax is much more strongly contracted behind, and the 

 structure of the mesosternum is different. 



90. Neosilusa moultoni, n. sp. 



Pale reddish -brown, rather shining, the sides and postero- external 

 angles of the elytra and the fifth and sixth abdominal segments 

 more or less pitchy; the antennae, legs and mouth-parts reddish- 

 testaceous. Length 2 mm. 



Very similar to Silusa (Neosilusa) eeyloniea, Kr., but at once 

 distinguished by the more shining fore-parts, paler coloration, 

 coarser but less rugose puncturation of the head and thorax, and 

 the less strongly contracted sides of the thorax posteriorly. Head 

 subpentagonal, the eyes moderately large and prominent, closely 

 and coarsely punctured, rather shining. Antennae moderately 

 long and stout, the first three joints subequal, the 4th slightly longer 

 than broad, the 5th as long as broad, the 6th to the 10th gradually 

 increasing in breadth, the 11th elongate oval. Thorax strongly 

 transverse, more than one and a half times as broad as long, widest
