440 A REVISION OF THE STAPHYLINIDjE OF AUSTRALIA, 



44. POLYLOBUS LONGULUS, Sp. n. 



Elongate, rather convex, very slightly narrowed both in front 

 and behind, reddish testaceous, shining; head, elytra and abdominal 

 segments 4-6 pitchy black, the posterior margin of the 6th segment 

 reddish testaceous. 



Head rather narrow, finely and not very closely punctured. 

 Antennae testaceous. Prothorax not much broader than long, 

 very slightly narrower in front than behind, very finely margined, 

 finely and not very closely punctured; anterior and posterior angles 

 rounded. Elytra at the base slightly wider than the prothorax, 

 broader posteriorly, considerably longer than the prothorax, very 

 finely and closely punctured ; the posterior margin feebly sinuate 

 before the external angles which are slightly produced. Abdomen 

 very slightly narrowed behind, rather finely and not very closely 

 punctured. Legs testaceous. Length 2^ mm. 



Shelley's Flats, New South Wales. 



Easily distinguished from any of the foregoing species by its 



rather long narrow form, by its short broad prothorax and by its 



evenly punctured pitchy black elytra ; it is more closely allied to 



Polylobus insecatus than to any other species with which I am 



acquainted. 



45. Polylobus notus, sp. n. 



Rather broad, moderately convex, narrowed both in front and 

 behind, reddish testaceous, shining ; antennae clothed with 

 fuscous pubescence except at the base ; head black ; prothorax 

 with four large punctures in the middle, the disc piceous ; the 

 external apical angles of the elytra and the 4th and 5th 

 abdominal segments pitchy black. 



Head rather broad, moderately strongly and very sparingly 

 punctured. Antennae somewhat thickened towards the extremity, 

 the first four joints testaceous, the others clothed with fuscous 

 pubescence ; similar in structure to those of the preceding species. 

 Prothorax transverse, as broad in front as behind, finely 

 margined, highly polished and very sparingly pubescent, with four 

 strong punctures on the disc, two considerably before the base
