Figures. — Figg. 7, 8, the female insect (ovipositor concealed). — Fig. 9, elytra of the male * (for the explanatory 

 letters, see p. 216, nota). — Fig. 10, anterior tibia of the female, inner face. — Fig. 11, ditto, outer face. 



Hab. Guatemala, Senahu in Vera Paz (Champion) ; Panama, Bugaba and La Caldera 

 in Chiriqui (Champion). 



A very distinct species, characterized by its anterior tibiae having a somewhat ovate 

 swelling in the middle, this being much more pronounced than in P. aztecus. The 

 inner margin of the swelling is somewhat in the form of a shell, overlapping the 

 border of the tympanum. The hind femora are feebly developed, and the inner 

 spurs of the posterior tibiae are short. In P. aztecus the inner spur of the hind 

 tibiae is half the length of the metatarsi. In size and facies P. podagrosus resembles 

 P. tibialis and P. niger.

The species of this genus are easy to recognize, the females having somewha the 

 facies of Coleoptera, the elytra in this sex being rather short and convex, and, when at 

 rest, forming a sort of box. The ovipositor is slender and straight, but in dried
