BY REV. T. BLACKBURN. 647 



Easily distinguishable by its uniform flavo-castaneous colour 

 interrupted only by the black spots on the prothorax and verructe 

 on the elytra together with its very broad prosternal longitudinal 

 furrow, which is quite as wide as in P. geographica, Baly. The 

 humeral callus is extremely feeble. 



N. Territory of S. Austi^alia. 



P. EXTRANEA, sp.nOV. 



5. Altitudine majori ad medium (vel fere pone medium) ely- 



trorum posita; obscure Ijrunneo-rufa, ut P. sternulis nigro- 



notata; prothorace in disco minus crebre punctulato, antice 



fortiter angustato, lateribus fortiter rotundatis; elytrorum 



callo humerali sat prominenti, puncturarum interstitiis 



apicem versus sat rugulosis; cetera ut P. sternalis. 



Very like P. sternalis \mt at once distinguishable from it (apart 



from colour) by its greatest height being not at all in front of the 



middle, by its prothorax being much less closely punctulate on 



the disc with its sides much more strongly rounded and its front 



part much more narrowed, and by its much better developed 



humeral calli. 



iS". S. AVales ; I do not know the exact habitat. 



P. SQUiRESENSis, Blackb. 



^. Leviter ovata ; minus lata; modice convexa, altitudine 

 majori (a latere visa) contra elytrorum marginem medium 

 (vel etiam magis retro) posita; sat nitida; nigra vel nigro- 

 picea, capite antennis pedibus (elytrorumque verrucis non- 

 nullorum exemplorum) plus minusve rufescentibus: capite 

 crebre subtilius punctulato; prothorace quam longiori ut 2| 

 ad 1 latiori, ab apice ultra medium dilatato, pone apicem 

 transversim impresso, inajqualiter (in disco puncturis 

 majoribus cum aliis minoribus intermixtis, ad latera con- 

 fertim grosse) punctulato, lateribus minus arcuatis nullomodo 

 deplanatis, angulis posticis obtusis; scutello Isevi vel vix 

 punctulato; elytris sub callum humeralem leviter depressis, 

 pone basin transversim impressis, crebre fortiter sat seriatim
