This species is very similar to P. redidypeatus, Kuw., 

 but the cephalic horn, although horizontally produced, 

 reaches scarcely half way to the clypeal margin, whereas 

 in Kuwert's species it attains to the front. The frontal 

 carinse terminate in slight tubercles before the margin of 

 the clypeus, enclosing a wide, deeply pitted and rugose 

 area. There are no wrinkles in front of the posterior 

 carinse, which are longitudinal. The punctures at the 

 sides of the prothorax are coarse and numerous and the 

 marginal grooves are punctured throughout and in front 

 are very large, deep and strongly curved. The general 

 form is more elongate than in the preceding species. The 

 elytra are similarly sculptured, but the strise are rather 

 finer and the interstices less convex.
