'Neiv Species of Slaphylinidae fro7H Singapore. 2G1 



abdominal segments, bright leddisli-testaceous : anteimae reddish, 

 the first two joints and the legs, testaceous. I<ength 2-5 mm. 



Very similar in build to A. myceto'phaga mihi, but more brightly 

 coloured, less shining and with differently formed antennae. Head 

 transverse, the temples small and rounded, the eyes large but not 

 prominent, very finely and sparingly punctured and pubescent. 

 Antennae with the 2nd joint a little shorter than the 3rd, the 4th 

 as broad as long, the 5th to the 10th transverse gradually increasing 

 in breadth, the 1 1th longer than the two pieceding together. Thorax 

 transverse, about half as broad again as long foiined as in mycetO' 

 2)haga, very finely and closely punctured, finely pubescent; the 

 sides each with two rather fine setae. Elytra a little longer and 

 broader than the thorax, transverse, very finely, closely and more 

 ilistinctly punctured than the thorax, finely pubescent. Abdomen 

 distinctly narrowed posteriorly, very finely and moderately closely 

 punctured and pubescent anteriorly, the seventh and eighth seg- 

 ments nearly impunetate; the sides sparingly setiferous, tlie apex 

 more closely. Middle and posterior tibiae each with two distinct 

 setae. 



Although the setae of the thorax and middle tibiae are 

 liner than those usually present in the sub-genus Dime- 

 irotii, yet owing to the distinctly narrowed abdomen and 

 the build of the thorax, it would appear that this species 

 has its closest aiiinity with this group. 



H<ih. Bukit Panjang, in rotting fruit. 



123. Atheta (Dimetrota) xylophila, n. sp. 



Black moderately sliining, tlie elytra pitch-brown; first three 

 joints of the antennae and the legs testaceous. Length 2-4 mm. 



Build of A. cadaverina Bris., but smaller, differently coloured, 

 the e^'es much larger and the elytra shorter. Head broad, the eyes 

 very large, their diameter much greater than the length of the 

 temples, very finely and moderately closely punctured, finely cori- 

 aceous. Antennae with the 2nd and' 3rd joints of equal length, 

 the 4th small, transverse, the 5th larger than the preceding, scarcely 

 transverse, the 6th to the 10th transverse, gradually inci-easing in 

 breadth, the penultimate fully twice as broad as long, the 11th 

 longer than the two preceding together. Thorax transverse, fully 

 half as broad again as long, very finely and rather closely punctured, 

 finely pubescent, rather more shining than the head and with similar 

 ground-sculpture; the sides with well developed setae. Elytra 

 scarcely longer, but a little broader than the thorax, transverse, 

 not sinuate posteriorly, the humeral angles with a seta; punctura-
