This species is certainly a Nephele. It differs from Pachylia in the form of the 

 wings. The latter genus appears to be strictly confined to the New World.

" S. America." 



Said to be allied to N. cenopion ; but as the primaries are described as crossed by two 

 purplish whitish bands, and the secondaries as spotted with white, with alternately 

 broad and narrow bands, I think the affinity cannot be very great. N. cenopion is an 

 African species. I doubt the locality of N. kadeni. 



6. Nephele aegentifera.
