more pronounced than in the two species above mentioned ; from 

 P. licydeni it is easily distinguished by the more slender facies, the 

 elytra more acuminate behind ; the sculpture of the elytra is nearly 

 identical, and the outer margins of the prothorax are much less 

 serrulate.

 antennas transversim leviter impressum ; prothorax ad medium 

 rotundato ampliatus, longtitudine fere quarto latior, basi apice haud

Large examples of this species are not unlike P. (jraiidix of medium 

 size, but the prothorax is not so wide, the elytra are narrower 

 and more convex, and the shape of the posternal process is very 

 different.
