above and below the clavate end of the streak. Hindwing with the costal border 

 paler and of a purplish tint ; the discal interspaces from the subcostal vein to the 

 abdominal margin pale yellowish-white, the traversing veins being broadly black, 

 followed by a submarginal and then a marginal row of small bluish-white pointed 

 dots disposed in pairs between the veins, the anterior of the former series being con- 

 fluent and obscurely dilated. Underside olivescent fuliginous-brown, the posterior 

 border of forewing and posterior area of the outer border of hindwing being suffused 

 with blue-black. Both wings with whitish markings, as on upperside. Body black, 

 thorax and abdomen with white bands ; collar and front, and palpi beneath white 

 spotted ; legs black ; forelegs with white bands ; middle and hind femora white 

 beneath ; antennae black ; eyes red, naked. 



Female. — Polymorphic and mimetic. 



First Fokm. — Isa, Moore (Plate 203, fig. 1, b. c). Upperside purplish blue- 

 black, brightest apically. Foreioing with a bluish-white broad short oblique upper 

 discal band from the costa to the middle median intersected by the veinlets ; a very 

 obscure bluish-white oblique streak at end of the cell, and a more or less complete 

 marginal row of small white spots, which latter are slender and somewhat elongated 

 at apical end. Hindwing with the medial discal area from the subcostal vein to the 

 abdominal margin bluish-white, intersected by the veinlets ; followed by a sub- 

 marginal and then a marginal row of blue-white spots. Underside uniformly 

 fuliginous-black, marked as above. Mimics the male of the Euplseine butterflies 

 Danisepa Rhadamanthus and D. Ramsayi. 



Expanse, 2^ to S^ inches. 



Second Form (Plate 203, fig. d, e.) Upperside purplish fuliginous-black, more 

 or less darker and blue tinted apically on the forewing. Forewing with a bluish- 

 white broad oblique upper discal band, intersected by the veins, as in the first form, 

 but the band is somewhat broader and less sharply defined, below which is a more or 

 less obscure elongated white-speckled streak with cleft outer end, and below this is a 

 similar cleft-spot between the median and submedian, followed below by a streak along 

 the posterior angle ; a more or less obscure white-speckled oblique streak at end of 

 the cell ; and a marginal row of small distinct bluish-white pointed spots, of which 

 two are disposed together between the veins, and the upper slender and elongate. 

 Eindiving with the basal and discal area bluish- white, this colour also extending, and 

 more or less coalescing with the submarginal row of large rounded spots, beyond 

 which is a marginal row of prominent smaller triangular spots in pairs, which latter 

 are usually conjoined between the veins. Underside more uniformly fuliginous- 

 black ; marked as on upperside. Mimics the female of Danisepa Rhadamanthus. 



Expanse, 3 to 3i inches.
