Closely allied to I. Silas, "Westw. $ . Soft pale-blue : 

 apical half of fore-wing black ; circular costal patch on 

 hind-wing large, conspicuous, glistening-whitish, broadly 

 ringed with blackish. Fore-wing : costa grey, edged with 

 pale-reddish near base, abruptly widening and deepening into 

 apical black before extremity of discoidal cell ; blue forming 

 an imperfect semicircle, having for its base the inner-margin 

 of wing, but not reaching anal angle, to which the apical 

 black (covering the entire hind-margin) narrowly extends. 

 Hind-wing : hind -margin edged with a black line ; three 

 tails precisely as in Silas, but less twisted ; inner-marginal 

 groove dark-grey, clothed and fringed with whitish hairs : 

 lobe of anal angle marked with a pale crimson-red spot, 

 outwardly black-dotted, and marked with a few bluish scales ; 

 a small, indistinct, similar spot immediately above it. Cilia 

 greyish in fore-wing : white in hind-wing (tinged with yellow 

 near anal angle). UNDER-SIDE. White, tinged with greyish: 

 one transverse ferruginous-red streak in fore-wing, two in 

 hind-wing ; costa of fore-wing, and hind-margin of hind-wing, 

 with an orange edging. Fore-wing : ferruginous-red streak 

 rather broad, straight from costa beyond cell, in direction of 

 anal angle, to second median nervule, where it abruptly 

 terminates ; a semicircular patch of grey on inner-margin 

 near base, and lying over it a curious row of long black 

 hairs springing from edge of inner-margin ; near anal angle, 

 above submedian nervure, an elongate blackish mark. Hind- 

 wing : first red streak as in fore-wing, from costal nervure 

 (before middle) as far as third median nervule, where it 

 narrows, and is thence a bi-angulated thin black streak to 

 inner-margin a little beyond middle ; outer red streak not 

 far from and almost parallel to hind-margin, narrowing and 

 becoming almost obsolete after passing discoidal nervure : 

 space between streak and hind-margin greyish, enclosing an 

 additional red spot between second and third median nervules 

 similar to that at anal angle, which is larger than on upper- 

 side, merged with the smaller red spot, and outwardly edged 

 with a bluish line ; from discoidal nervure the hind-marginal 

 edging is black. 



$ . Violaceous- whitish, suffused with blue from bases. 

 Fore-wing : border narrower and dusky -blackish. Hind- 

 wing ; costa with a dusky border, widest at apex ; from it
