former, these together with 11 forming a three jointed club, 11 wider 

 than 10, and nearly twice as long, subovate, bluntly pointed. Pro- 

 thorax as broad as long, widest just before middle, with a strong 

 longitudinal basal fovea and two round lateral foveae on either side, 

 one basal and one submedian; puncturation as on head. Elytra 

 -transverse, with four basal foveae; rather strongly raised at shoulders. 

 Metasternum with two prominent tubercules close together on disc 

 midway between posterior and intermediate coxae, each tubercule 

 crowned with a small bunch of hairs. Undersurface of abdomen with 

 a wide shallow impression down middle, apex of fourth segment on 

 either side at outer edge with a prominent lamellated ridge or tooth 

 directed obliquely hindwards, its axis longitudinal. Intermediate 

 and posterior trochanters bluntly toothed. Four front femora stout, 

 hind femora each with a prominent black carina traversing slightly 

 less than the middle half of its uppersurface, inner basal halves 

 -deeply excavated, excavation apicaly overhung by a wide thin plate. 

 Hind tibiae strongly arcuate, each with a blunt oblique protuberance 

 or tooth near base, this crowned with long fasciculate setae, a very 

 prominent sharp tooth on inner edge of uppersurface at about middle, 

 and a shorter sharp tooth on inner edge of lowersurface a little 

 nearer base. Legs with puncturation rather stronger than elsewhere. 

 Inner claw of anterior tarsi trifid. 



Length, 2.8 mm. 



$ Differs in having joints 4 and 5 of antennae not appreciably 

 wider than 3, abdomen not impressed beneath; no armature on legs 

 And ventral segments. 



Habitat.— Victoria: Healesville (F. E. Wilson), Belgrave (F. B. 

 Wilson and C. Oke). 



This species seems to have affinities with mamillatus , Lea*, in its 

 tuberculate metasternum, and leana, Raff.,5 in the possession of a 

 sub-basal tooth on its hind tibiae. Its very remarkable hind femora 

 and tuberculate metasternum, however, serve easily to distinguish it 

 from the latter species, and the armature of the hind tibiae readily 

 separate it from the former. 



It is sometimes a difficult matter on mounted specimens, however 

 well set, to see the lower submedian tooth on the hind tibiae, although 

 the upper one is always prominent. This latter, viewed from some 

 directions, is seen to be somewhat lamelliform as in victoriae^^ King. 

 Also from some directions the fourth and fifth antennal joints do not 

 appear to be anything like as wide as they actually are. 



My Healesville specimens were taken from moss growing on old 

 logs, and those from Belgrave were sieved from fallen leaf debris.
