The genus is peculiar to America, and has a wide range 



from Chili to Lower 



r 



California. Seven or eight species are known.

Chaudoir named this species P. scaritides (Perty) in the Salle collection ; but it is 

 far from agreeing with Perty 's description or his figure, which represent a species with 

 strongly transverse thorax. P. scaritides is said to be from Piauhy, in the interior of 

 Brazil ; but specimens which I took on the Upper Amazons perfectly agree with it, 

 and are very different from the present Mexican species.
