Larva. — It is figured by Maassen and Weymer, figs. 96, 97, and 98. It agrees in general 

 with that of Nudaurelia dione, the body being cylindrical, armed with numerous straight stiff 

 unbranched sharp spines. 



Pupa. — The pupa is figured in the same plate. It is elongated, and the abdomen ends in 



a point. [C. Oberthur (Etud. Lep. Comp., IV bis, 1910) discusses this species, as ThyeUa 



zambesia, giving good photographic figures. He separates two new races as rectilinea and 



zanguebarica.] 



ACANTHOCAMPA FELDERI (Rothschild). 



Nudaurelia felderi Rothschild, Nov. Zool., II, p. 42, 1895. 



Imago. — "Wings Tery similar to red varieties of N. belina (Westw.), but without the ocellus 

 on the fore wings, there being only a small square vitreous spot. Another difference is the very 

 broad white border to the ocelli of the hind wings.

[Mr. J. H. Watson has kindly sent an abstract of the treatment of Acanthocampa and allied 

 genera by Aurivillius in Arch. f. Zool., 1904, p. 18. Aurivillius here recognized two genera as 

 follows: 



(1) Gonimbrasia Butler. Type nictitans (Fabr.). With the anterior tibiae short, shorter 

 than the tarsi, and armed at the end with two spines; joints of antennas almost simple. This 

 includes Acanthocampa Pack, and Angelica Distant. The following species are referred to it: 

 belina Westw., osiris Druce, said Oberth., zambesina Walk., tyrrhea Cram. 



(2) Bunaea Hubner. Type alcinoe (Cram.). Anterior tibia? scarcely shorter than the tarsi, 

 and not armed at end; joints of antenna? with four teeth. Includes ThyeUa Wallengr. Here 

 are placed the species caffraria Stoll, aslauga Kirby, goodii Holland, hersilia Westw., and 

 oubie Guer. 



Angelica Distant, 1903, was based on zambesina, which is placed above in Acanthocampa. 

 Oberthur (1910) refersitto ThyeUa, but it is not the original genus of Wallengren, which Aurivillius 

 correctly associates with Bunaea. Judging from the markings (compare Plates CVT and CVTH) 

 belina stands apart from zambesina and tyrrhea, these latter seeming to be congeneric. On this 

 basis Angelica might possibly be separated from Acanthocampa, but Oberthiir's zambesina, 

 subsp. rectilinea, approaches belina in its markings.] 



BUNAEA Hubner. 



Bunaea Hubner, Verzeichniss bek. Schmett., p. 154. 

 [Bunaea] Rothschild, in part, Nov. Zool., II, p. 38, 1895. 



Imago. — s and 9 . Head not so prominent as in Salassa, the front not wide, and it narrows 

 toward the labral region; the scales are not erect, but laid flat on the surface. Antennas of 

 male plumose, wide, the joints rather long, flattened, and scaled above, with long pectinations 

 provided with long dense cilia, ending a little before the subfiliform tip; the basal and distal 

 pectinations long and slender, and of equal length; there are 33 joints, the last three with ves- 

 tigial branches; female antennas with short pectinations extending almost to the end, which 

 bears long setas; the distal ones tooth-like, one- third as large and long as the basal ones. 



Palpi unusually small and short, depressed, not reaching to the front, blunt at the end, 

 and the third joint not distinct; when denuded, a button-like short round third joint is present. 

 Thorax stout. 



Legs rather stout, all the tibias without spines. For tibia when denuded rather thick, 

 not bearing any terminal spines; the odoriferous sack or nartheca lanceolate-oval, swollen in 

 the middle, the end slender and prolonged; about two-thirds as long as the tibia itself; at the 

 base overlapping it is a broad flat ovate secondary sack, which is as wide as the tibia. A 

 similar scale-like process or sack is observable in Nudaurelia cytherea. 



Fore wings falcate in c? , scarcely so in 9 ; costa straight to near the. apex, where it is well 

 curved; apex acute; the outer edge incurved. Hind wings triangular, with the apex almost 

 pointed, the outer edge curved in d 1 , nearly straight hi 9 ; inner edge somewhat rounded,
