622 MR. A. G. BUTLER ON THE SPHINGIDZ. 
Genus 20. NEPHELE, Hiibner (Zonri1a, Walker). 
Nephele, Hiibner, Verz. bek. Schmett. p. 133. gen. 5 (1816). 
1. NEPHELE AQUIVALENS. 
Pachylia equivalens, Walker, Lep. Het. viii. p. 191. no. 5 (1856). 
Sierra Leone (Morgan). Type, 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. 
Orneus enopion, Hiibuer, Samml. exot. Schmett. ii. pl. 159. figs. 1, 2 (1806). 
Deilephila enopion, Boisduval, Faune Ent. de Madag. p. 75. no. 8 (1833). 
Philampelus enopion, Walker, Lep. Het. viii. p. 182. no. 14 (1856). 
Zonilia enopion, Walker, J. 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 ROSH. (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, Schaufuss, Nunquam Otiosus, i. p. 16 (1870). 
«S$. America.” 
Said to be allied to V. @nopion; 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. WV. e@nopion is an 
African species. I doubt the locality of V. kadeni. 
6. NEPHELE ARGENTIFERA. 
Zonilia argentifera, Walker, Lep. Het. viii. p. 194, no. 4 (1856). 
Port Natal.
