I took many specimens of this species at St. Paulo, 
Amazons, on the leaves of trees in the forest. One pair 
were taken in copula. I have examined Guerin^s type of 
P. nigricorniSj and found it to agree with the palest of 
my specimens. It was probably taken in the same 
locality as mine, by Osculati, who spent some time at 
the village of St. Paulo on his voyage down the Amazons.
