112 NOTES ON AUSTRALIAN COLEOPTERA, 



however, is much more like a Heteronyx superficially than is P. 

 helceoides. The basal joint of the hind tarsi is considerably shorter 

 than {in P. baldiensis about equal to) the 2nd joint.

Minus elongata ; pubescens, capite prothoracis margine antico 

 sternis (his densissime) pygidio pedibusque longe villosis ; 

 rufescens vel flavo-brunnens ; capite subcrasse, prothorace 

 confertim sat subtiliter, elytris dupliciter (et crebre sat sub- 

 tiliter et minus crebre magis crasse), punctulatis ; prothorace 

 quam longiori (et postice quara antice) fere duplo latiori, 

 lateribus crenulatis sat fortiter arcuatis, angulis posticis 

 obtusis fere rectis ; elytris singulis apice manifeste rotundatis.

 Feminse antennarum flabello brevi 6-articulato, articulo 4° intus 

 producto; tarsis posticis brevibus.

 Very near R. heterodactyla, Germ. ; the principal differences 

 that I notice are as follows : — The flabellum of the antennae is 

 evidently shorter (in heterodaclyla male it is by measurement as 

 long as the basal 4 joints of the tarsi together, in this species 

 clearly less), the puncturation is throughout a trifle stronger and 

 less close, the prothorax is more narrowed in front with its sides 

 very evidently more strongly rounded, the elytra (regarded indi- 

 vidually) are manifestly more rounded at the apex.
