Secondaries below sulphur-yellow throughout, two additional brown spots, on the interno-median and second median interspaces. c. Secondaries below flesh-pink with yellowish margins, the whole surface mottled with indistinct olive spots, a dusky longitudinal streak through the cell; other markings as in var. a, but less distinct. d. Secondaries inclining to ferruginous excepting towards apex, where the ground-tint is yellow, a yellowish streak above a black-mottled dusky longitudinal streak through the cell; the whole remaining surface mottled with olive and black ; other markings as in var. b, but larger. In addition to the above modifications, the black border on the upper surface of the primaries varies both in width and length ; but its inner edge is always more or less dentate-sinuated. 5. TERACOLUS VENUSTUS, sp. n. 3 . Above like a small specimen of T. aurigineus, but with narrow external black borders to the wings, a smaller spot at the end of the discoidal cell of primaries, and the black band of secondaries terminating at third median branch ; below it also differs in having the apex and outer border of primaries and ground-colour of secondaries sandy buff instead of sulphur-yellow. Expanse of wings 36 millim. Kilima-njaro (F. J. Jackson). Allied to the preceding is a species of which we have received no less than nine specimens from Somali-land, but which, from an omission to examine them individually, I confounded with the T. chrysonome of Klug ; I describe it as follows :- TERACOLUS HELVOLUS, sp. n. Nearly allied to T. chrysonome, the wings a little shorter and smaller; the indication of a band across the secondaries much more decided ; the discal zigzag band of primaries below ending in a black spot; the apex and outer border of primaries and entire ground-colour of secondaries on the under surface flesh-pink instead of sulphur-yellow. Expanse of wings 33-35 millim. T. chrysonome measures 40-44 millim. in expanse; it is a wider-ranging species than T. helvolus, which is probably restricted to Somali-land. 6. TERACOLUS COMPTUS, sp. n. Nearly allied to T. antigone, which we have in both sexes from Accra, but larger, the wings decidedly longer, the black external border of primaries narrower ; the black spots of secondaries much smaller ; the internal band on the male more or less prominent, more so than in our specimen of T. antigone, in both males before me; the orange apical patch of the male broader and not so red • the black apical patch in the female connected by a line of black |
