Male. Anterior wings dark iudigo-blue. with pale retleelmus towards outer margins, ai til with the 

 following white spots : — two subcostal and linear, divided by first subcostal nervule, the inner one much the 

 longest (in some specimens the last is preceded above by a narrow linear spot, situated above costal 

 uemire, which is absent in the form ngured) ; a very large and irregularly* shaped spot occupying apical 

 portion of cell, followed by a small one placed between first and second median nervules \m some specimens, 

 B8 in the one figured, this is pieeeded inwardly by a small pale bluish spot) ; a submargiual series of seven 

 pale bluish spots, four subnpical placed hetwecn the nervules, and three, which are very small, mar anal 

 audits these an- preceded by a large subojuidrnle spot between sec ond and third median nervules, with a 

 small one beneath it, both of which are also pale bluish, which is also the colour of the pseudo s<vnt -gland 

 or brand, situated beneath and parallel to third median nerunY. Posterior wings dark indtgo-btne. with the 

 diseoidal and costal area ohvaeeousdawn, and with the following pale bluish spots :— three submarginal 

 near apex, the upper one small and somewhat indistinet isoim-linir-s ah.--nl i, a small spot n\ end of eell 

 (in some specimens there are three), it marginal series of small spots near anal angle, preceded by two 

 (and sometimes four) slightly larger spots; four elongate white fascia' ei.niinencing near base, and situated 

 two between third median nervals and submediau nervure, and two on abdominal margin. Underside of 

 livings paler and more olivaceous, the bluish spots much paler, a large additional white spot between second 

 and third median nervules, and with the pseudo Bcent-gland coneolorous. Posterior wings marked as 

 above, but with the submarginal spots more numerous and continuous ; a long white streak ami two linear 

 spots in cell, and four linear white spots surrounding apieal portion ol' eell. Head and [)mra\ above Uaek ;

 submarginal series of very pale bluish spots; three large white streaks in cell, the ape\ of which is 

 surrounded by five white spots, the two lower ones being longest, and with the four basal and ud bom ina I 

 fasciae as in male. Underside of wings olivaceous-brown, marked and spotted generally as above, but with

This i& evidently a Malay race of E. rhadtnnttH tints, Fabr., a species which I follow Moore 

 and Butler in considering as typically represented in Northern India. It possesses also another 

 and very distinct Boraean race, described as E. LowiL The principal difference between these 

 three species or races is that of a gradually increasing melanism, which is least iu the North 

 Indian E. rhadamanthus and greatest in the Boruean form E. LoinL
