[Received June 16, 1886.] (Plates XXXVII. & XXXVIII.) SATURNIIDiE. A T T A C U S ALBIDUS, sp. n. (Plate XXXVII. fig. 1.) d • The primaries very similar to A. ploetzi, but the white band is closer to the outer margin, four round white spots between the apex and the anal angle. Secondaries pure white excepting the outer margin, which is narrowly bordered with reddish brown, with black and fawn-coloured lunular markings as in A. ploetzi; the vitreous spot long, narrowly edged with black, bordered on the inner side with yellow. The underside the same as above. Head and thorax reddish brown, a wide white band at the base of the thorax, the abdomen brown banded with white ; antennae and legs pale yellowish brown. The female the same as the male, but slightly more reddish in colour, and with all the vitreous spots considerably larger. Expanse, d 7 inches, 5 6| inches. Hab. West Africa, Cameroon Mountains. Mus. Druce. This very fine species comes into the group containing A. vacuna, Westw., A. ploetzi, Weymer, from both of which it is at once distinguished by the pure white secondaries. ANTHER^A DOLABELLA, sp. n. (Plate XXXVIII. fig. 2, o* •) d. Primaries chrome-yellow, crossed by three irregular black bands, beyond which, along the outer margin, are a series of dusky patches, the base of the wing shaded with pink. Secondaries bright pink, broadly bordered with chrome-yellow, from the apex to the anal angle with several indistinct dusky black patches ; nearest the anal angle a wide black band, dividing the two colours, crossing from near the apex to the inner margin ; a large round deep yellow ocellus with a wide black border, on the outer edge of the black is a ring of bluish-fawn colour ; in the centre of the ocellus is a very small vitreous spot. Head and thorax and upperside of abdomen bright pink, the underside of abdomen chrome-yellow banded with black ; tegulse chrome-yellow; antennee black; legs black and yellow. Expanse 4~ inches. Hab. East Central Africa. Mus. Druce. This very beautiful species is quite unlike any other known to me. BUN^A PYGELA, n. sp. (Plate XXXVIII. fig. 1, d •) d. Primaries uniform pale pinkish brown, darkest along the costal margin ; the outer and inner margin narrowly edged with pink ; underside as above, but shaded with dark yellow from the base to about the middle; a small black spot at the end of the PROC.
