New Species of Staphylinidae from Singapore. 233 



apex with a very long seta, the central pair with a short seta at the 

 apex ; eighth ventral segment divided by a flask-shaped excision 

 into two pointed lobes the apex of each furnished with a long seta, 

 the side-margins of the segment with a small tooth bearing a long 

 seta; seventh ventral segment with broad emargination limited by 

 a seta on either side at the posterior margin, the surface in front 

 with a triangular impression (the base corresponding to the emargina- 

 tion) extending the whole length of the segment, the posterior part 

 of which is studded with minute granules. Sixth and fifth segments 

 impressed'in the middle line. 



$. Eighth dorsal segment cut into four pointed processes, the 

 lateral being a little longer than the median pair, and each with a 

 long seta at the apex and a small tooth on the external margin also 

 carrying a long seta ; central processes each with a short seta; the 

 lateral excisions deeper and narrower than the median one; eighth 

 ventral segment with six processes, the lateral much shorter than the 

 rest which are of equal length, the central pair broader and rounded 

 at the apex and furnished with a bunch of short yellow setae, the 

 others each with a long seta; the three central excisions are moder- 

 ately broad and rounded at the apex of each. 



Hab. Mandai, in wet rotting leaves on the edge of a 

 jungle stream. Three examples. 



Tachyporini. 

 46. Conosoma robustum, n. sp. 



Robust, convex, black, moderately shining; the abdomen rather 

 densely clothed with short golden pubescence. Antennae long and 

 slender, the first four joints and the last testaceous. Legs reddish 

 testaceous, the outer margin of the anterior tibiae closely set with 

 short black pectinations. Length 5 mm. (in well-extended examples). 



Build of C.bipustulatum, Gray., but more robust, broader, and 

 more convex. Head very finely and sparingly punctured, with scanty 

 cinereous pubescence, . and without ground-sculpture. Antennae 

 slender, reaching a little beyond the posterior angles of the thorax, 

 the 1st and 3rd joints elongate, of equal length, the 2nd half the 

 length of the 3rd, the 3rd and 4th subequal, the 5th to 10th each 

 longer than broad, subequal and compressed, 11th elongate, oval, 

 longer than the 10th. Thorax broader than the elytra, scarcely 

 transverse, the posterior angles rounded, the posterior margin 

 narrowly and obscurely ferruginous; very finely and rather closely 

 punctured, and covered with a short fine griseous pubescence. 

 Elytra as long as the thorax, slightly narrowed behind, with punctur-
