Expanse of wings 55 millim. 2 • Above with the black external area much narrower (about one half the width of the typical form), but the veins blackened from the middle ; the black spots better defined, owing to their not being obscured by the wide border ; the basal area also less suffused with blackish. Primaries below with narrower discocellular bar and discal belt; the veins towards apex and on secondaries less broadly black-bordered: secondaries chrome-yellow, the submarginal spots smaller and only connected by grey scales ; the marginal spots of the ground-colour shaped more nearly as in B. calypso. Expanse of wings 55 millim. 2 . Fdda, 20th October, 1885 ; 3 • Wadelai, 29th March, 1887. Var b. 3 . Above with the black markiugs less strongly defined, the oblique discocellular line of primaries sometimes obliterated ; the apical area of primaries and the ground-colour of secondaries creamy whitish, the saffron-coloured markings replaced by pale yellow; the veins only blackened at their outer extremities. Expanse of wings 57 millim. 2 • Above white, not obscured at the base; black markings nearly as in B. calgpso 2 > but w i t n grey-bordered white dashes on the apical area of primaries, and the marginal spots of secondaries obscured with grey towards anal angle : apical area of primaries below creamy white, the veins across it very slenderly black ; the subapical black belt narrow; secondaries slightly pearly, the black spots small, the other characters as in the male. Expanse of wings 56 millim. 3. Kangasi, 18th November, 1883; 3 2 • Wadelai, 16th January, 1887. Apart from all less constant characters, the whole of the varieties of this species can be at once distinguished from B. calypso by the six subapical and submarginal black spots on the upper surface of the secondaries, which are perfectly defined in both sexes, by the regular and unbroken character of the subapical bar or belt on the under surface of the primaries, and by the more or less developed black borders to the veins on the under surface of the secondaries. 107.
