58 LEPIDOPTERA HETEROCERA 
hairy. Hindtibia in cf strongly dilated, with hair-pencil and usually with a rather broad but not long 
terminal process, in both sexes with all spurs. Abdomen usually somewhat crested, sometimes quite 
smooth. Frenulum fully developed. Forewing with costa arched, apex usually acute, termen almost 
smooth or waved, little convex (in some species elbowed at R9), oblique, cell somewhat less than one- 
half, DC. incurved, SC! from cell, nearly always free, very exceptionally anastomosing shortly with C, 
SC? normal, R! separate, R? normal, M! separate; hindwing with apex usually rounded, termen irre- 
gular, strongly tailed at R? and slightly or rather strongly at R', tornus somewhat produced, ceil less 
than one-half, DC? incurved, C closely approximated to ceil for some distance, occasionally with short 
fusion basad, SC? approximated to R!, R? very characteristic, M! separate. cf genitalia with uncus 
bifurcate, gnathos with broad lip, harpe angulated, penis pestillate, coremata present. 
Lanva. — Moderately stout, with slight protuberances on prothorax and eighth abdominal, green 
in colour; feeding on species of Nerüium, etc. (Moore, Lep. Ceyl. Vol. 3, p. 437, t. 197; 1. 15, etc. ). 
Pupa. — Rather slender, segmental incisions, eyes and spiracles well marked, form cylindrical, 
regularly tapering, abdomen light brown, black-spotted, a supra-anal plate and eight terminal hooks. 
Except in the curious variability of the crests, this genus exhibits remarkable uniformity of struc- 
ture. As with most large genera where this is the case, a more thorough revision is needed than the 
scope of the present work admitted; we have done little more than catalogue the described forms. They 
exhibit well-marked sexual dimorphism.

1) As this species is unknown from China, whence Donovan's specimen purported to come, the synonym cannot be regarded as absolutely 
certain. But even if the figure could be proved to represent a remarkable aberration of carzssi»:a, Butler, the name of sozarta could not be applied, 
being a homonym.
