African Species of the Genus Acraea. 109 



marginal border as in ^ but paler. Underside. F.-w. dull 

 greenish grey, sometimes pinkish from subbasal to subapical 

 area. Nervules and rays well marked, blackish. Spots as on 

 upperside. H.-w. pale greenish grey, spots and markings as in 

 ^ but usually paler. In some examples the spots and hind- 

 marginal border are as in the ^ but the basal red is absent and 

 the other colours only faintly represented. Abdomen black 

 above, ochreous beneath, and with ochreous lateral spots. 



Examples of A. egina from British E. Africa frequently 

 have the red colour of a more brilliant and rosy tinge 

 than in W. African examples, and the colouring of the 

 underside is very brilliant. In the f -w. the apical inter- 

 nervular spaces are deep orange, and areas la and lb 

 bright pink. In the h.-w, the base is rose pink, the sub- 

 basal spots and nervures are surrounded with green, the 

 discal area is deep orange with a median pink suffusion, 

 and the hind-marginal border is green with a black inner 

 edge and black on the ends of the nervules. 



Many examples from N.E. Rhodesia are of this brilliant 

 colouring with the apical red streaks of the harrisoni form. 

 Some ot the examples taken by Neave on Chirui and 

 Chishi Is., L. Bangweolo, are of the harrisoni form. 



A. eciina, f. harrisoni. 



In this form there are in the (^ (and less obviously in the 9 ) 

 streaks of the red colour in the internervular spaces of the 

 apical portion of the f.-w. The underside colouring is much 

 more brilliant than in ordinary examples. In the 9 the 

 f.-w. is much suffused with reddish and the h.-w. is red as 

 in the ^ but rather paler and the black spots smaller. 



A. egina areca, subsp. 



(^ . Expanse 70-80 mm. F.-w. orange red with a trace of 

 an oblique whitish subapical bar; costa, apex, and hind riiargin 

 brownish black and a suffusion of same colour at base and on 

 nervures. Black spots as in egina but larger and the subapical 

 discal row sometimes confluent with that on end of celL H.-w. 

 orange red with black suffusion at base, but of much less extent 

 than in egina egina, and a black hind-marginal border about 2 mm. 

 wide rarely slightly paler between the nervules. Spots as in. 

 egina egina but often smaller, less clearly defined, or obsolescent. 



Underside. F.-w. as above but much paler. H.-w. base dull 

 red followed by orange, inner margin pale yellowish green, and 

 A greenish dusting round spots and nervules. Discal area
