African Species of tlie Genvs Acraca. 179 



examples in the Oxford collection were taken in November 

 to January by Mr. Wiggins. 



The species is quite distinct and is not a form of douUe- 

 dayi, though some of the grey % $ are not unlike the $ of 

 that species. 



A. eqiiatorialis (Uiaemia, subsp. PI. V, f. 5 ( (^ ). 



(J. Expanse 50-60 mm. Differs from typical eqxatorialis in 



. having the wings more sparsely scaled and the ground-colour 



paler and more delicate. Both wings have a brownish basal flush 



and submarginal spots are frequently present in f.-w. lb, and 2. 



$ resembles ^ but wings are more rounded and abdomen is 

 black with white lateral spots. 



67. ACRAEA ELLA. PI. II, f. 7 ( (^ ). PI. XI, f. 8. 



Aci-aea ella, Eltringham, Novit. Zoo]., xviii, p. 151 (1911). 

 Angola (Bihe). 



(J. Expanse 50-60 mm. Wings dull to golden or pinkish 

 ochreous. F.-w. with a slight dusky basal suffusion, costa, apex, 

 and liind margin very narrowly black, rather broader at apex. 

 Apical area usually rather richeryellow than remainder of wing. 

 A submai'ginal row of internervular black rays which rarely 

 roach the margin. Nervule ends black. Black spots as follows : — 

 In cell a spot very sliglitly beyond origin of 2. A double spot on 

 upper part of discocellulai's. Beyond cell a discal row of spots 

 of whicli the first in 10 is rather nearer base than the others, 

 and usually elongate, the second, third and fourth in 6, 5, and 4 

 nearly in a .straight line at right angles to costa, the fifth 

 separate and nearly in the middle of area 3. A spot in 2 just 

 below origin of 3, and beneath this but slightly nearer margin a 

 spot in lb, and in same area a spot (sometimes doubled) about 

 2 mm. before origin of 2. 



H.-w. with some black basal suffusion, and a hind-marginal 

 border formed by a narrow black marginal line on which are 

 rather flat, not always clearly defined, internervuhir arches en- 

 closing spots of the ground-colour. Black spots corresponding 

 to those on underside but usually only fuiiitl}- indicated near 

 inner margin. 



Underside f.-w. like the upperside but without basal sutt'usion, 

 paler, and with two spots at base of costa. H.-w. paler than on 

 upperside, base, inner margin, and area Ic splashed with pink. 

 Marginal border as above but much more cleai'ly defined. Black 

 spots as follows : — Discal spots, one in 7 about middle, one in 6 

 about 3 mm. nearer to margin. Beneath this and slightly nearer
