538 REVISION OF THE GENERA COLPOCHILA, ETC. 



COLPOCHILA SETOSA, Sp.nOV. 



Elongato-ovata ; minus iiitida ; rufescens, antennis elytrisque 

 pallidioribus ; pectore valde hirsute, elyti'is setis sat longis 

 suberectis sparsim vestitis, abdomine sparsim setose ; capite 

 (hoc sat brevi) crebre rugulose subtilius (clypeo paullo crassius, 

 et parte pone oculos Isevigato, exceptis), prothorace subfortiter 

 sat crebre, elytris (his geminato-striatis) sat fortiter sat crebre 

 subrugulose, pygidio (hoc exempli typici deformi ?) crasse 

 obscure rugulose, punctulatis ; antennis 9-articulatis ; pro- 

 thoracis basi bisinuata, quam margo anticus hujus tertia 

 parte latiori, angulis posticis (superne visis) subrotundatis ; 

 elytris apice sutui-ali vix obscure prominentibus. 



Maris antennarum flabello stipite sat breviori, 4-articulato, — 

 articulo 1° quam ceteri vix breviori, — stipitis articulo ultimo 

 intus acute breviter dentato. [Long. 9, lat. 4^ lines. 



Fern, latet. 



The prothorax is very nearly twice as wide as long ; from the 

 front angles (which are acute but only moderately prominent) the 

 sides (viewed from above) diverge to about the middle where they 

 are feebly arched and then scarcely converge hindward to the hind 

 angles ; they are not at all sinuate. 



This species is allied to C. testaceipennis, Macl., gracilis, Blackb., 

 &c.,-— but is extremely distinct. 



Central Australia ; McDonnell Ranges. 



N.B. — My collection contains an example labelled " Mts. of 

 Victoria " which I cannot distinguish from the type of C setosa, 

 although I think the discovery of the sexes of both forms might 

 probably show them to be distinct. 



COLPOCHILA GIBBOSICOLLIS, Sp.nov. 



C. setosfe valde affinis ; differt prothorace multo convexiori 

 (subgibboso) et tibiarum anticarum dentibus externis crassis 

 obtusis, tertio (ab apice enumerate) cum ceteris comparato 

 majori. [Long. 7-8, lat. 4-4f lines.
