wing as above but basal black area broken i;p into distinct black 

 spots, two additional spots to outer series on inner margin ; the red 

 lunules of outer marginal border replaced by distinct olivaceous 

 lunules ; the neuration olivaceous, widely so on basal half of median 

 nervure. 



Exp. 62 millim. 



Hob. North-Eastern Rhodesia. 



This species appears to be near A. periphancs, Oberth., 

 and its allies ; it can however be distinguished by its more 

 pointed wings, and the peculiar olivaceous colouring of the 

 neuration of hind wingjs belov/. 



AcR.EA ANGOLANUS, sp. nov. (Plate I, figs. 4, 5.) 



(J. Upper-side. Fore wing black, a quadrate hj'aline-white 

 patch beyond middle of cell ; two round patches below, of which 

 the upper is the larger, three similar subapical patches, of which 

 the upper two are quadrate, the lower round and nearer outer 

 margin. Hind wing black, cell and area round, except below third 

 median nervule yellow. 



Under-side. Fore wing paler than above, apical area olivaceous 

 with nervures and dashes between blackish ; median nervure and 

 nervules olivaceous, an elongated reddish-brown mark on costa at 

 base ; hyaline markings as above. Hind wing, yellow area as 

 above, the black replaced by olivaceous with nerAiiles and dashes 

 between black, basal black area replaced by reddish-brown ; the 

 following black spots in basal area : two at base, one in costal lobe, 

 one in cell, and three within and three at lower edge of basal 

 red area ; anal angle reddish-brown. 



$ . Similar to male but slightly larger and paler and with outer 

 margin of hind wing not so concave. 



Exp. (^ 56-64 millim.; $ 62-66 millim. 



Hah. BiHE District, Angola. 



A long series of both sexes of this new form was 

 obtained. It is closely allied to A. orcas, Sharpe, but may 

 be separated by its greater size, the marldngs of fore 

 wing being large and hyaline instead of small and yellow, 

 the greater extent of yellow area of hind wing and the 

 much paler ground colour below. I also figure a very 

 beautiful aberration of the female in which markings of 

 fore wing are hyaline-yellow and the yellow area of hind 

 wing is extended in rays to outer margin.
