New Species of Staphylinidae from Singapore. G5 



the 9th considerably broader than the 8th, the 10th as broad as 

 the 9th, 1 1th conical. Thorax transverse, formed as in T. halophilus, 

 Kies., but shorter, widest at the junction of the first and middle 

 thirds, slightly rounded and narrowed anteriorly, more strongly 

 contracted backwards to the rounded posterior angles; disc longi- 

 tudinally impressed on either side of the middle line; sculpture and 

 pubescence similar to that of the head. Scutellum shining, im- 

 punctate. Elytra about one-fourth longer than the thorax, a little 

 infuscate posteriorly; sculpture finely granular and coriaceous, no 

 distinct puncturation visible; pubescence yellow, fine and sparing, 

 but much more distinct than on the fore-parts. Abdomen very 

 finely coriaceous, impunctate, more shining than the fore-parts, 

 very finely and very sparingly pubescent. 



Hab. Sembawans;, on the bank of a stream. 



10. Aploderus testaceus, n. sp. 



Rufo-testaceous, shining : last six joints of the antennae and disc 

 of the elytra infuscate. Length 3"5-4 mm. 



Head transversely suborbicular, front deju'essed between the 

 antennal tuberosities, anterior margin elevated and produced; eyes 

 large, their diameter much greater than the length of the temples; 

 orbit with a juxta-ocular furrow; puncturation fine and sparing. 

 Antennae with the 1st joint elongate, clavate, the 2nd and 3rd 

 joints subequal, 4th slightly, the following more strongly transverse, 

 gradually increasing in breadth, the last joint conical. Thorax 

 transverse, a little broader than the head, widest just behind the 

 anterior angles, narrowed posteriorly in a nearly straight line, 

 posterior angles completely rounded; disc with a very line median 

 impressed line (sometimes obsolete), sides broadly and feebly im- 

 pressed, puncturation exceedingly fine and sparing. Elytra a 

 little longer than the thorax, transverse, the puncturation closer 

 and more distinct than that of the thorax. Abdomen, except for 

 a few setiferous punctures, laevigate; ground-sculpture very fine, 

 coriaceous, scarcely visible. 



c?. Seventh ventral segment bluntly, triangularly produced in the 

 middle, and rather deeply emarginate on either side; the sixth 

 feebly impressed in the middle in front of the posterior margin, 

 the impression rather thickly punctured and clothed with still 

 whitish pubescence. 



Hab. Mount Faber district, in dung. Appears to be 

 scarce.
