(clypeo subtilius) punctulato; antennis quam corporis dimi- 



dium vix longioribus; protliorace quam longiori ut 10 ad 4 J 



latiori, in disco acervatim subfortiter (ad latera — his late 



subplanatis — grosse) punctulatis, angulis anticis mucronatis 



posticis obtusis minus rotundatis; elytris confuse sat fortiter 



sat crebre (quam P. variolosce, Marsh., magis fortiter minus 



crebre) punctulatis, puncturis suturam versus multo subtili- 



oribus, interstitiis transversim confuse (postice quam antice 



vix magis fortiter) elevatis, parte laterali oblique extrorsum 



modice (quam P. augitstce, 9 minus fortiter) directa; elytris 



quam conjunctim latioribus vix longioribus. Long. 7|, lat. 



5J lines. 



This is one of a group of closely allied species {augusta, montana, 



<fec.). From augusta it differs inter alia by its shorter form 



(viewed from above), its decidedly greater convexity (very evident 



viewed from the side), its wider pro thorax, the considerably finer 



puncturation of the elytra near the scutellum, its elytra not 



having a conspicuous lateral dilatation about the middle; from 



dehilitata by the much less fine and close elytral sculpture; and 



from moidana which is its nearest ally by the considerably more 



transverse form of its prothorax, which is quite well marked by 



measurement, and looks much greater still to the eye. From 



variolosa, Marsh., and its immediate allies it is very distinct on 



account of its form being (when viewed from the side) much more 



elongate with the curve of its upper outline much less convex.

P. DEBILITATA, Blackb. 



The type of this species remains, so far as I know, unique. 

 The size and closeness of the punctures on its elytra are very 

 much as in variolosa, Marsh. As the locality is one from which 

 more specimens of a valid species might reasonably have been 

 expected, I think the unique example — notwithstanding much 

 difference of puncturation from the somewhat numerous specimens 

 of P. montana that I have seen — may possibly be only an 

 aberration of that insect.
