The upperside ground colour is rich silky brown. The forewing has the cell filled with a broad orange-yellow streak which is subapically deeply indented above; a small discal orange-yellow spot present in interspace 1; a much larger, similarly coloured discal spot between veins 2 and 4, on the inner side touching the cell between veins 3 and 4; a subcostal white preapical spot and a quadrate double spot in interspaces 4 and 5, placed obliquely forward to the subcostal spot; this spot whitish above, orange below. Hindwing uniform, with an irregular curved, transverse, upper postdiscal orange patch extending from just below vein 3 to interspace 6, the portion in interspace 6 often detached. Underside ground colour: forewing brown, apex pale purplish irrorated (sprinkled) with minute dark transverse striae and dots, orange markings as on the upperside but paler; hindwing uniform pale purplish irrorated with minute dark dots and transverse striae. Antennae, head, thorax and abdomen dark brown; beneath, palpi, thorax and abdomen concolorous with the tint of the underside of the hindwing.[1]

gollark: That doesn't seem particularly sensical, which I suppose you might expect for anything randomly pulled out of a long video.
gollark: You *really* like saying "boomer papers", don't you.
gollark: It's "not real" in the sense that numbers and differential equations and perfectly accurate triangles and such do not exist in reality, but do allow you to make really good models of it.
