BY REV. T. BLACKBURN, 177 



A species very unlike any other known to me (among those 

 having the elytra highest considerably in front of the middle) on 

 account of the close rather fine puncturation of the elytral disc 

 and the extreme inconspicuousness of the elytral verrucse which 

 are concolorous (or nearly so) with the derm. In these respects 

 and in colouring it resembles P. alta and inornata, which, however, 

 belong to the subgroup having the greatest height of the elytra 

 much further back. I do not find any noteworthy sexual 

 differences beyond those common to the genus.

(J. Late subovata, valde convexa, altitudine majori (a latere 

 visa) ante elytrorum marginem medium posita ; modice 

 nitida; ferruginea, in capite maculis 2 in prothorace verrucis 

 externis et in elytris maculis vel vittis nonnullis indetermina- 

 tis verrucarumque nonnullis piceis, corpore subtus plus 

 minusve infuscato ; capite sat ci'ebre fortius punctulato;. 

 prothorace quam longiori ut 2|^ ad 1 latiori, ab apice longe 

 ultra medium dilatato, pone apicem transversim impresso, sat 

 insequali, crebre subfortiter subrugulose (ad latera subgrosse) 

 punctulato, lateribus modice arcuatis haud dej^lanatis, angulis 

 posticis rotundatis; scutello sparsissime vel vix punctulato; 

 elytris sub callum humeralem haud depressis, pone basin 

 haud impressis, subseriatim minus fortiter subsequaliter 

 punctulatis, verrucis parvis sat numerosis minus distinctis 

 vix seriatim instructis, interstitiis rugulosis hie illic transver- 

 sim rugiformibus et puncturas nonnihil obscurantibus, parte 

 marginal! sat lata a disco (per sulculum subobsoletum ad 

 apicem continuum) sat manifeste divisa, calli humeralis 

 margine interno a sutura quam ab elytrorum margine laterali 

 vix magis distanti; segmento ventrali basali sparsim subtilius 

 punctulato. Long. 3, lat. 2| lines (vix). 

 Notable for the rugulose interstices of its elytra which consider- 

 ably obscure the puncturation and tend to run here and there into 



short transverse wrinkles. Resembles creherrima in the above
