the costa. The forewings are very narrow and the apex rather sharp, while the apex of the 

 hind wing is much rounded. The tails are very long, nearly three times as long as the wing 

 itself. There is no trace of an ocellus on the hind wings. The outer margin of the forewings 

 for a quarter of an inch is dull orange-red, as is the outer edge of the hinder pair. The tails are 

 entirely dull orange-reci, except the ends, which are green.

ARGEMA BESANTI Rebel. 



[Argema besanti Rebel, Verh. Ges. Wien., 1895, p. 69.] 



This species is congeneric with A. mimosx. The example in the British Museum is from 

 a point 150 miles northeast of Mombasa, East Africa. It is a singidar, small species, expanding 

 2f to 3 inches. Fore wings short, triangular; ocellus not connected with the costa, but a broad 

 tooth or projection extends toward it from the costa. Ocellus of hind wings small, venetian- 

 red in the middle, an outer brown ring, no vitreous line or spot. A broad lilac-brown extradiscal 

 band, edged broadly witliin with white, winch crosses the discal veins. The extradiscal band 

 on the hind wings is faintly marked. The tails are expanded at the ends, mostly lilac brown, 

 and green at the end.

Imago. — Head as in Argema, the front of the same width and smooth; S antennae not so 

 suddenly subfiliforrn at tip as in Argema; with short joints; pectinations long. In 9 A. artemis 

 the antemial joints are very long, in their middle the distal pectinations are about one-half 

 as long as the proximal, becoming gradually shorter toward the tip; the pectinations are clavate, 

 with four to six setae near and at the end. Labial palpi rather large, distinct, 3(?) jointed, 

 broad, the third joint not distinct, longer than in Tropaea. Maxillae separate, but distinct, tliick, 

 not quite reaching to the middle of the palpi, those of artemis not quite so long as in T. luna. 

 In A. selene the palpi are well developed, broad, curved up and nearly reach the front of the 

 head, and the third joint is just visible; [the palpi] conceal the tongue unless depressed. 



Fore wings longer, outer edge longer, a little more pointed at the apex and the costa is 

 inclined to be more curved than in Argema and much more so than in Tropaea; outer edge long, 

 not scalloped, and the wing tends to be more falcate, though this is not a generic character. 



Hind wings with much shorter and broader tails than in Argema and Tropaea, and the tip 

 of the tail is not so wide, or scarcely so, than the middle. 



Venation: This genus differs from Argema in the longer discal cell and in the longer stalks 

 of veins IIIj, III 2 . In the hind wings the distance between the origins of III 3 and IV is twice 

 that between TV t and IV 2 , being just the reverse of what obtains in Argema. 



From Tropaea it differs in the discal cell of the fore wings being longer; in the subcostal 

 area being narrower, though it varies in this respect, that of selene being narrow, and that of 

 artemis wide, more as in Tropaea. The discal veins are remote from the origin of the vein IIL. ; 

 vein VII tends to be longer than in Tropaea, indicating in selene a more primitive origin for the 

 genus, though in A. artemis it is shorter. In the hind wings the discal area is also longer than 

 in Tropaea, and the ocellus is much nearer the outer edge of the wing, while the three veins of 

 the tail originate much farther from the discal veins. 



Markings: Discal spots of moderate size {selene) or small {artemis), those of the fore wings 

 free from the costal edge, having no stalk.
