454 A REVISION OF THE STAPHYLINID^ OF AUSTRALIA, 



posterior margin ; 6th segment with two setigerous punctures near 

 the posterior margin, one on each side of the middle. Legs 

 ferruginous ; tarsi pale testaceous. Length 2f mm. 



Fremantle, King George's Sound, West Australia ; in ants' 

 nests. 



Some specimens have the elytra and abdomen of a much darker 

 ferruginous colour than the rest of the body. 



63. Dabra cuneiformis, sp. n. 



Ferruginous, very strongly narrowed behind, moderately convex, 

 somewhat shining, very finely pubescent, the sides setose ; head, 

 prothorax and elytra very finely and closely punctured ; abdomen 

 dark ferruginous, shining, extremely finely and sparingly punctured. 



Head broadly transverse, very finely and closely punctured. 

 Antennge reddish testaceous, the apical joint considerably longer 

 than the four preceding joints together, acuminate at the 

 extremity. Prothorax at the base more than twice as broad as 

 long, slightly narrowed in front, moderately convex on the disc, 

 flattened near the sides, very finely and closely punctured ; the 

 sides furnished with seven or eight short erect setae ; the posterior 

 angles moderately produced. Elytra about as long as the 

 prothorax, finely and closely punctured ; the sides somewhat 

 reflexed and furnished with three or four erect setae ; posterior 

 margin deeply and rather abruptly sinuate just before the external 

 angles which are strongly produced. Abdomen strongly narrowed 

 behind, extremely finely and very sparingly punctured ; the lateral 

 setae and setigerous punctures arranged as in the preceding species. 

 Legs reddish testaceous. Length 2-2^ mm. 



King George's Sound, West Australia ; in ants' nests. 



This species is closely allied to Dabra myrmecophila in whose 

 company it has been taken, but can be separated at a glance on 

 account of its wedge-like form and less convex upper surface ; the 

 lateral setae are not so long, the external angles of the elytra are 

 more strongly produced and the terminal joint of the antennae is 

 comparatively longer.
