Among its allies structurally (having no subbasal elytral 

 impression) this species is superficially distinct by its subseriate 

 elytral puncturation together with the almost regular rows of 

 small rather closely placed verruca?, which are concolorous with 

 the derm. There is, however, a tendency to the elytra being 

 marked with dark vittae (which in some examples are very well- 

 defined), and on these vittte the verrucje are concolorous with 

 them and not with the general surface.

P. aUicolce affinis; differt colore toto fprothoracis maculis non- 

 nullis, et elytrorum verrucis, nigris exceptis) testaceo- 

 castaneo; prothorace in disco magis fortiter minus crebre (ad 

 latera grosse confluenter) punctulato; scutello nitido sparsim 

 fortiter punctulato; elj'tris in disco magis fortiter punctulatis, 

 verrucis valde perspicuis (baud transversim elongatis) in 

 seriebus iutegris circiter 9 sat crebre sat regulariter dispositis; 

 cetera ut P. alticola. 



Femina quam mas paullo magis convexa. Long. 4, lat. 24 lines. 



Although superficially very different from P. alticola, this 

 spacies is structurally very close to it. The notably coarser punc- 

 turation of its upper surface, however, forms a reliable distinction, 

 and the colour and markings are so differ-ent thai; it is unlikely 

 any varieties approximate much to alticola. With the exception 

 of some black marks on the prothorax (a longitudinal blotch on 

 either side of the middle and a few small sjoots nearer the margins, 

 in the type) and numerous small round black verructe (about 15 

 in a series) placed in about 9 series very evenly over the whole 

 elytx'a, the entire insect is of a uniform pale chestnut colour. 

 There is, in the type, also a common dark blotch on and around 

 the suture a little in front of its middle, apparently caused by the 

 intervals between two or three verrucas being stained with dark 

 colouring similar to that of the verruca?.
