I received two exactly similar specimens of this species from 

 Mr. Carlos Bruch.

Hah. Panama. 



This species must not be mistaken for P. jxinmnensis Jac, 

 which it resembles somewhat in its markings ; but the last-named 

 species has very shining el}i;ra without basal depression, set with

 fulvous band is placed below, not at the middle ; the antennse also 

 have the last three joints flavous instead of four.
