<S 2 • Differs from L. roliria {L. dyrta, Felder) in the costa of 

 the fore wing being less strongly arched, in the hind wing being 

 narrower, with a more elongate and slender tail, and in the 

 darker and more uniform colour of the upperside. In markings 

 it differs slightly as follows : — c? . Upperside : fore wing — costal 

 and preapical white spots minute and tinged with ochraceous ; 

 hind wing with a postdiscal series of five blind black ocelli and 

 a dark subterminal sinuous line beyond. Underside differs in 

 being darker and more suffused with purple, especially on the 

 hind wing; also on the hind wing the series of postdiscal ocelli 

 are more uniform in size, the apical not larger than the subtornal 

 ocellus, and their centres are not disintegrated. — 2 • Upperside : 

 fore wing — the oblique white discal band narrower than in 

 L. roliria : the series of black spots on hind wing very prominent, 

 margined inwardly and outwardly with pale ochraceous white. 

 Underside more or less resembling the underside in L. rohria, 

 but richer in colouring, the ocelli on the hind wing sometimes 

 bipupilled but never disintegrate.
