It extends along the eastern coast of Australia at least as far 

 north as Wollongong in New South Wales, where I have taken it. 



Platynus pla7iipe7in{s, MacL, I do not know in nature, but the 

 description suggests to me its probable identity with P. margi- 

 nellus so strongly that I am unwilling to regard it as a valid 

 species unless it be proved that the range of P. marginellus does 

 not extend as far north as Gayndah, or a comparison of the type 

 with P. marginellus discloses specific differences between them. 



Loxocrepis lugiob7'is, Motsch., (which is placed in Masters' 

 'Catologue' in Coljjodes) seems to me a species of Platynus. I 

 have been unable to satisfy myself of its identity with P. inargi- 

 nellus, but the description appears to me not inapplicable to that 

 species; and I therefore suggest that it might be placed under 

 P. marginellus with perhaps a little doubt. In this connection 

 it may be noted that M. Tschitscherine has recently recorded the 

 fact that Motschulsky's types are almost all lost,! so doubtless 

 the determination of L. luguhris is wholly dependent upon the 

 description. 



Platynus queenslandicus, n.sp. 



9. Small, elliptical, depressed; prothorax subquadrate, a little 

 wider at base than apex, basal angles obtuse; elytra much wider 

 than prothorax, finely striate, 1st interstice with an elongate 

 striole at base, 3rd with three minute punctures — anterior on 

 course of 3rd, two posterior on course of 2nd stria. Brown (or 

 piceous); prothorax with the explanate margins testaceous; elytra 

 with 1st interstice and lateral margin (also part of 8th interstice) 

 testaceous; legs fusco-testaceous; antennae fuscous. 



Head smooth, lightly and obliquely narrowed behind eyes, 

 lightly convex between eyes, lightly and widely biimpressed 

 between antennae; eyes large, rather prominent but subdepressed 

 (not protuberant and hemispherical). Prothorax broader than 

 long (1-4 X r? mm.), depressed; sides lightly rounded, widest 

 about middle, almost equally narrowed to apex and base (but a 

 little more lightly so to base); anterior margin lightly emarginate;
