new Species o/'Lycwnidte. 201 



Chilades Alherta, sp. n. 

 Catochrysops cychpteris, Hutler, V. Z. S. 1888, p. 08. 



cJ" . Wings above ashy brownish, brightly shot witli lilac; 

 borders and veins smoky brown, discoceUuhirs and fringe also 

 smoky brown ; secondaries with a submarginal row of smoky 

 brown spots, the last but one (near anal angle) blackish, 

 tlie last three spots witli white outer edges; the fringe of 

 primaries towards external angle and that of secondaries with 

 whitish basal line; body noimal: under surface much as 

 in Euchrysops ci/clo/>(eri's, excepting that tiie last three sub- 

 marginal spots on the secondaries are surmounted by orange 

 zones, tlie last spot short and linear. The female is larger and 

 bluer than the male, with well-deHned blackish outer border 

 and discocellular dash on primaries ; the costal borders of all 

 wings broadly dusky ; the secondaries with conspicuous orange 

 zones to the last three submarginal spots on the upper 

 surface : the under surface is whiter than in the male, the 

 markings somewhat reduced in size and less conspicuous. 



Expanse of wings, c? 27, ? 30 millim.

Iraota Nicevillei, sp. n. 



Iraota mtecenas, Moore, Lep. Ceylon, i. p. 102, pi. xl. figa. 2, 2 a, $ 

 (1880-81). 



This species differs from the true /. nicecenas (dry phase of 

 /. timoleou) in the much more restricted and metallic Morpho- 

 like colouring of the patches of colour on the upper surface. 

 According to Moore these patches are metallic blue; but it 

 would be more correct to call them green, as it is difficult to 

 get them so placed as to eliminate all yellow from the blue; 

 and, when facing the light, the colouring is glittering metallic 

 green. On the under surface the differences are not striking 

 between the two species, but the white discoidal markings 

 are less silvery in the Ceylonese insect and the discal white 

 lunules on the primaries are reversed, their concavities being 

 directed towards the base instead of the outer margin. Our 

 examples, which are females, differ from the rich purple 

 females of /. iimoleon in their longer secondaries with more 

 slender tails ; indeed, in their general aspect they more nearly 

 resemble the male than the female of /. timoleon. 



Expanse of wings 89-i5 millim.
