Described from two females, .<ix males, and three nymj)hs, taken at 
Ancon, Canal Zone, Panama, Xovember 4, 1013, by .Air. James Zetek. 
'I'hey were found on the branches and under the bark of a fallen dead tree, 
in company with a Tenehrionid l)eetle, Dolievm angustaia Champion. 
This species agrees very well with the description of P. brasUiensis, 
except for the italicized portions of the above description, and the smaller 
size. BrasUiensis is said to he described from the male, though the draw¬ 
ing clearly shows the specimen to be a female.
