1888.] FROM EaUATORIAL AFRICA. 77 



Var. a, i . Slightly smaller, the black cuneiform costal dash of 

 primaries replaced by an oblique black line ; all the black markings 

 more sharply defined ; the white apical dashes narrower, the black 

 spots of the subapical and submarginal series of secondaries smaller ; 

 below the oblique black dash at end of cell of primaries interrupted, 

 the apical area of primaries and ground-colour of secondaries clear 

 sulphur-yellow ; the veins less distinctly black, the costa, two 

 abdominal streaks, and the pale spots of tJae external border saffron- 

 yellow. Expanse of wings 55 miilim. 



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 miilim. 



2 . Fdda, 20th October, 1885 ; 6- Wadelai, 29th March, 1887. 

 Var b. S • Above with the black markiugs less strongly defined, 

 the obhque discoceliular 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 vellow; the 

 veins only blackened at their outer extremities. Expanse of wings 

 57 miilim. 



2 • Above white, not obscured at the base ; black markings 

 nearly as in B. cahjpso 5 , but with 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 veips 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 miilim.

 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.

One injured male only was obtained : we have a similar male 

 from the Congo. It differs from typical B. calypso in the white
