622 ME. A. G. BUTLER ON THE SPHINGIDjE. 



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

 Nephele, Hiibner, Verz. bek. Schmett. p. 133. gen. 5 (1816). 



1 . NEPHELE iEQUIVALENS. 



Pachylia tequivalens, Walker, Lop. Het. viii. p. 191. no. 5 (1856). 



Sierra Leone (Morgan). Type, B.M. 



This species is certainly a Ne])kele. It differs from Pachylia in the form of the 

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



2. NEI'HELE J5NOPION. 



Omeus tenopion, Hiibner, Samml. exot. Schmett. ii. pi. 159. figs. 1, 2 (1806). 

 Deilephila tenopion, Boisduval, Faune Ent. de Madag. p. 75. no. 8 (1833). 

 Philampelus tenopion, Walker, Lep. Het. viii. p. 182. no. 14 (1856). 

 Zoni/in tenopion, 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 ros^e. (Plate XCIV. fig. 3.) 

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



Boma (Mrs. Monteiro). Type, B.M. 



5. Nephele kadeni. 



Pachylia kadeni, Schaufuss, Nuuquam Otiosus, i. p. 16 (1870). 



" S. America." 



Said to be allied to N. asnojnon ; 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. 2V. amopion is an 

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



6. Nephele argentifera. 



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

 Port Natal.
