and two somewhat nearer together at a similar distance from the 

 anterior margin ; anterior and posterior angles rounded. Elytra 

 considerably wider and longer than the prothorax, finely, 

 irregularly and not very closely punctured, the external apical 

 angles broadly and the posterior margin narrowly margined with 

 pitchy black ; the posterior margin feebly sinuate before the 

 external angles which are slightly produced. Abdomen a little 

 narrowed behind, very finely and closely punctured. Legs 

 testaceous. Length 2|mm. 



Sydney, New South Wales. 



A very distinct species approaching Polylobus insecatus, but 

 differing in its larger size, broader and more strongly punctured 

 head, in its comparatively longer and dusky prothorax, and in 

 having the external apical angles of the elytra black. P. notus 

 and P. acceptus are more highly polished and less closely pubescent 

 than any of the other species of the genus with which I am 

 acquainted. 



46. Polylobus acceptus, sp. n. 



Broad, moderately convex, somewhat narrowed both in front and 

 behind, reddish testaceous, shining ; antennae fuscous, finely pube- 

 scent, the first three and the terminal joints testaceous ; head, 

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

 segments pitchy black. 



Head rather strongly, irregularly and very sparingly punctured. 

 An tenme slightly thickened towards the extremity; 1st and 2nd 

 joints elongate, 3rd and 4th much smaller, 5-10 very slightly 

 transverse, larger, 11th acuminate. Prothorax transverse, as 

 broad in front as behind, finely margined, castaneous and highly 

 polished, with four punctures on the disc similar to those of 

 P. notus. Elytra finely, irregularly and not very closely punc- 

 tured, more strongly punctured near the sides, the external apical 

 angles broadly pitchy black. Abdomen very finely and not very 

 closely punctured. Legs testaceous. Length 1^ mm. 



Watson's Bay, Sydney, New South Wales. 



Very closely allied to the preceding species. It may, however, 

 be known by its smaller size, slightly more convex form and by its
