on to a thin carina that curves round to near the front of an eye. Eyes large, 

 facets inconspicuous. Prothorax large, sides strongly rounded, lateral gutters 

 fairly deep, margins fairly wide on sides, narrow at apex, but absent from base, 

 front angles somewhat acute ; a conspicuous conical tubercle in middle, crowning 

 the summit of a fairly large, subapical depression ; punctures very minute, 

 becoming larger but obsolete in front angles. Elytra with narrow, geminate 

 striae, containing narrow, distant punctures; interstices scarcely separately 

 convex, and with minute punctures. Sides of prosternum, sides and base of 

 metasternum, with rather dense piliferous, granulate punctures; metasternum 

 with some large punctures near apex and small ones elsewhere. Abdomen with 

 apical segment strongly narrowed in middle; pygidiura with fairly dense small 

 punctures. Claw-joints large, dilated to near apex, claws large and strongly 

 arched at base. Length, 9 mm. 



Hah. New South Wales: Wingham, one specimen from a bandicoot's nest 

 (W. du Boulay). Type, I. 15396. 



The general appearance is suggestive of species of Onthophagus, such as 0. 

 glahratiis and mnrchisoni, with the prothorax armed, but the claw-joint and claws 

 are those of Macropocopris ; it is the only species at present known of that genus 

 with the prothorax armed. 



PEDARIA ALTERNATA sp. nov. 



$ Black, shining, most parts with a bronzy gloss ; antennae, palpi, and tarsi 

 more or less reddish. With short, pale setae, rather sparsely distributed. 



Head wide, moderately convex between eyes; with rather sparse punctures 

 becoming dense (but normally concealed) at base, sides flattened but with fine 

 margins. Clypeus with two projections marking the sides of a semicircular 

 notch. Prothorax widely transverse, front angles obtusely produced, hind ones 

 obtuse, sides obliquely decreasing from near apex to base ; a large, almost impunc- 

 tate, medio-basal depression, its front angles obliquely produced, between depres- 

 sion and sides with large, rather dense and suboblong punctures, elsewhere with 

 sparser, smaller, and more rounded ones. Elytra feebly dilated behind shoulders; 

 with deep, sharply defined striae, four interstices on each elytron conspicuously 

 wider than the others, and each with a row of rather distant, setiferous punctures. 

 Metasternum with a large median depression, connected with mesosternum by a 

 median ridge; sides with dense and large punctures, smaller elsewhere, but all 

 sharply defined. Front tibiae moderately long, obtusely tridentate externally, 

 apex with a rather strong inner hook. Length, 4-5-5 mm. 



$ Differs in being less parallel-sided ; head smaller, with denser and rather 

 coarse punctures; prothorax with denser and larger punctures, and with many
