angle; median branches at nearly equal distances apart; a transverse veinlet and 

 sliort basal internal vein : hindwing broad ; exterior margin convex, scalloped, some 

 females with a spatulate tail from end of upper median; cell extending to half the 

 iving ; first subcostal at one-half before end of the cell ; upper discocellular oblique, 

 lower bent inward, radial from their angle ; lower median at one-half before end of 

 the cell ; submedian much curved in the middle. Body stout ; abdomen moderately 

 short; antennae with a slender club. Sexes dissimilar; female polymorphic. 



Larva elongated, cylmdrical, anterior segments scutellated, third, fourth, and 

 fifth segments thickened, head attenuated ; with an ocellated spot on each side of

ILIADES PARINDA (Plate 60, Fig. \ a,h). 



Male. Blue-black : forewing with a broad discal transverse pale greyish band 

 formed of streaks between the veins, the band decreasing to the anterior end : 

 hindwing with the outer area from middle of the cell pale greyish-blue; a discal 

 submarginal and a marginal row of blue-black oval spots, the two latter series 

 being sometimes confluent. Female. Brownish-black : forewing with broader band 

 extending more towards the costa, and more or less of an ochreous-grey colour : 

 hindwing similar to the male, except that the colour is outwardly duller and inwardly 

 more or less tinged with ochreous-grey ; some specimens also have a red streak at 

 base of the cell on the forewing. 



Expanse b\ to 6 inches. 



Larva smooth, glossy green, with a whitish lateral lower band from sixth to 

 anal segment, a broad oblique similar-coloured band ascending the eighth, ninth, 

 and tenth segments, shield edged with whitish anteriorly, and its posterior dorsal 

 end bordered by a transverse blackish marked crest, a similar crest also across the 

 fourth segment, ending on each side in a large ocellated spot. Pupa green or olive- 

 brown. Feeds on Citrus dtcumana, &c. 



Differs from I. Polymnestor in the band on the forewing being longer and 

 broader, more especially in the female, in which sex it is of a different tint, and in 

 the pale colour of the hindwing extending more towards the base in both sexes, this 

 portion of the wing also being of a different tint. 



"Western, Central, and Southern Provinces. Plains and hills, in forest and open 

 ground. Taken at Colombo from April to end of the year ; elsewhere at various 

 times. Has a slow, majestic flight ; flaps the wings a great deal. Quite fearless, 

 and is easily caught hovering over flowers " (Hutchison).
