of its elytral interstices, which are closely impressed with confused 

 punctures, many of which are scarcely smaller than the seinate 

 punctures, so that the latter do not appear very conspicuous to a 

 casual glance. This last named chai'acter distinguishes the 

 present insect readily from all its near allies. 



With this insect commences a short series of species agreeing 

 with the preceding two in most of their characters, but differing 

 in their less nitid upper surface.

Late {^) vel minus late (2) ovalis; convexa; minus nitida; tota 

 testacea (exemplorum vivorum elytris in disco plus minusve 

 viridi-nitentibus) ; antennis sat gracilibus minus elongatis; 

 capite crebre rugulose punctulato; prothorace quam longiori 

 ut 2^ ad 1 latiori, antice modice angustato, grosse rugulose 

 (ad latera etiam magis grosse) punctulato, ad latera late 

 oblique leviter impresso, angulis anticis sat acutis posticis 

 nullis, lateribus sat arcuatis; scutello punctulato; elytris 

 sequalibus, baud vel vix striatis, puncturis seriatis rotundis 

 parvis valde regulai'iter dispositis (in seriebus confertim dis- 

 positis sicut puncturse 3 longitudinem interstitii latitudini 

 sequalem occupant), interstitiis planis confertim subaspere 

 minus subtiliter (sed quam series multo subtilius) punctulatis, 

 parte laterali nullo modo rugulosa ut interstitia punctulata 

 et puncturis majoribus (his quam serierum puncturae paullo 

 minus subtilibus) confuse nee acervatim impressa. Long. .3-4, 

 lat. 2^-3 lines. 



Rather closely allied to the preceding (P. Sitnsoni) but differing 

 from it inter alia by its still more rugulose prothorax and by the 

 sculpture of its elytra, there being considerable difference in size 

 between the seriate and interstitial punctures, in consequence of 

 which the elytral series are very much more conspicuous in the 

 present insect than in Simsoni. 



S. Australia ; near Adelaide.
