Rio Jutahi, 1st Februaiy, 1875. 



I do not follow Mr. Scuclder in his views respecting 

 this species (BuU. BufF. Soc. ii. p. 248). In the case of 

 two names applied to the same insect by one author, the 

 first described, even where the only indication is an earlier 

 pagination, should be considered typical. In the present 

 instance I adopt " P. orion " as indicative of the Amazon 

 type, which differs from that of the Antilles.
