(Plates XXXVII. & XXXVIII.) 
SATURNIIDS. 
ATTACUS ALBIDUS, sp. n. (Plate XX XVII. fig. 1.) 
3. 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; antenne 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, ¢ 7 inches, 2 63 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 distin- 
guished by the pure white secondaries. 
ANTHERHA DOLABELLA, sp. n. (Plate XXXVIII. fig. 2, ¢.) 
3. 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 ; 
tegulee chrome-yellow ; antennz black; legs black and yellow. 
Expanse 44 inches. 
Hab. East Central Africa. Mus. Druce. 
This very beautiful species is quite unlike any other known to me. 
Buna pyGELa, n. sp, (Plate XXXVIII. fig. 1, ¢.) 
3. 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. Zoo. Soc.—1886, No. XXVII. 27.
