2oo LLOYD'S NATURAL HISTORY. 



This is - genus of " Orange-Tips " which, with Hebomoia, 

 practically replaces Callosune in the Indo-Malayan Region, 

 and extends to some of the Austro-Malayan Islands, though in 

 India and Ceylon the ranges of these three genera overlap. 

 There are no African species, though Wallengren erroneously 

 referred Callosune annce to this genus. 



The body and palpi are rather hairy, the antennae slender, 

 with a pear-shaped club. The wings are broad, more robust 

 than in Callosune, yellow or white, with the apical half of the 

 fore-wings black, filled up with a large orange or yellow band 

 (sometimes white in the females), and the" hind-wings are bor- 

 dered with black. Beneath, the wings are generally yellow, 

 more or less flushed with brown, and frequently with traces of 

 rust-coloured eyes with silvery pupils. They are generally 

 larger insects than Callosune, averaging about two inches in 

 expanse. The sub-costal nervure of the fore-wings is four- 

 branched, with two branches emitted before the end of the 

 cell, and the third and fourth forming a larger fork than in 

 Callosune ; but the most important character is that the first 

 discoidal nervule is thrown off from the sub-costal nervure 

 distinctly beyond the cell, instead of rising from the cell, as 

 in the last-named genus. 



The type is Ixias pyrene (Linn.), one of the largest yellow 

 species, which is common in India and South China.
