I took many specimens of this species at St. Paulo, 

 Amazons, on the leaves of trees in the forest. One pair 

 were taken in cojntld. I have examined Guerin^s type of 

 P. nigricornis, 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.
