 (Plates XXXVII. & XXXVIII.) 



Saturniidj?. 



Attacus 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, narrowlv edu;ed 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 tbe vitreous spots considerably larger. 

 Expanse, S 7 inches, $ 6| inches. 



Hah. West Africa, Cameroon Mountains. Mus. Druoe. 



This very fine species comes into the group containing A. vacunn, 

 Westw., A. ploetzi, Weymer, from both of which it is at once distin- 

 guished by the pure white secondaries. 



Anther^a dolabella, sp. n. (Plate XXXVIII. fig. 2, S •) 



(S . Primaries chrome-yellow, crossed by three irregular black 

 bands, beyond v^hich, 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 tbe 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 ; antennae 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. 



BunjEA pygela, n. sp. (Plate XXXVIII. fig. ], d'.) 



(J . Primaries uniform pale pinkish brown, darkest along the 

 costal margin ; the outer and inner margin narrowly edged with
