the side) evidently nearer to the base. In both this species and 

 the preceding the continuance of the shallow sulciform impression 

 (which marks the distinction between the discal and marginal 

 regions of the elytra) to the actual apex causes the ajopearance, 

 when the insect is viewed from the side, of the suture being 

 produced hindward in a short mucro.

 visa) sat longe ante elytrorum marginem medium posita; 

 minus nitida; castanea (prothoracis maculis nonuullis, ely-

 nigris), antennis apicem versus infuscatis; capite protho- 

 raceque (colore excepto) fere ut P. Chapuisi, sed hujus 

 lateribus vix manifesto deplanatis; scutello puncturis 

 nonnullis impresso; elytris sub callum humeralem triangu-

 crebre subreticulatim rugulosis sed minus distincte punctu- 

 latis, sulculo subhumerali minus determinato et ante apicem

 sutura quam ab elytrorum margine laterali manifesto magis 

 distanti: epipleuris et segmenti basalis ventralis sculptura

 Distinguished among its near allies (apart from probably 

 variable characters) by the sides of its prothorax markedly less 

 explanate, the feebleness of the distinction between the elytral 

 disc and margins (the submargi'nal sulcus failing entirely before 

 the apex so that viewed from the side there is no appearance of a 

 sutural projection), and' the humeral callus with its inner margin 

 considerably nearer to the lateral margin than to the suture. 

 The sculpture of the elytra resembles that of /■'. raucipennis in 

 consisting of rugulosity mostly concealing the puncturation but 

 it is feebler and less granulose than in that species so that the 

 puncturation is not quite so much obscui'ed.
