Genus 20. Nephele, Hiibner (Zonilia, Walker).

1. Nephele ^quivalens. 



I'achylia mquivalens. Walker, Lep. Het. viii. p. 191. no. 5 (1856). 



Sierra Leone [Morgan). iype, B.M. 



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. 



2. Nephele ^nopion.

 Zonilia (enopion, Walker, /. c. Suppl. i. p. 33 (1864). 



Bourbon, Madagascar. 



-3. Nephele densoi. 

 Zonilia densoi, Keferstein, Entomol. Notizen, p. 14. fig. 5 (1870). 

 Madagascar. 

 I have been unable to refer to this species. 



4. Nephele eos^. (Plate XCIV. fig. 3.) 

 Nephele rosa, Butler, P. Z. S. 1875, p. 14. no. 30. 



Boma [Mrs. Monteiro). Type B.M. 



5. Nephele kadeni. 



Pachylia kadeni, Schaufiiss, Nunquam Otiosus, i. p. 16 (1870). 



" S. America." 



Said to be allied to iV^. mnopion ; 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 afiinity cannot be very great. N. cenopion is an 

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



6. Nephele argentifeea. 



Zonilia argentifera, Walker, Lep. Het. viii. p. 194. no. 4 (1856). 

 Port Natal.
