African S'pecies of the Genv.s Acraea. 139 



5 . Resembles (J but ground-colour rather less brilliant, and 

 a trace of a pale subapical bar just beyond f.-w. discal spots. In 

 one example before me tlie ground-colour is pale brownish 

 ochreous and there is a distinct whitish subapical bar. Abdomen 

 black above with large yellowish lateral spots. Pale yellowish 

 beneath. 



Wet season form (^ . Ground-colour as in dry form but all the 

 black markings larger. A black marginal border about 1 mm. 

 wide round both wings, narrower at angle of f.-w. and from angle 

 to base of h.-w. All spots much larger than in dry form. In 

 f.-w. an extra spot near base of lb and a hind-marginal spot in la 

 immediately below the spot in 2. In h.-w. a well-developed 

 spot in 3, close to end of cell. 



Underside much as in dry form, but spots larger in f.-w. and in 

 h.-w. 3 the extra spot is present. In f.-w. there is a narrow 

 submarginal line of ochreous along hind margin, and in h.-w. a 

 similar line rather broader and bounded on its inner edge by a 

 fine black line. 



9 • Ground-colour dull brownish ochreous to sepia black, 

 spotted as in ^J. The blackest forms show a small white sub- 

 apical bar in f.-w. the development of which becomes less the 

 more nearly the ground-colour approaches that of the J . 



Weymer's ab. decora is a (^ with much of the f.-w. ground- 

 colour replaced by black. It is merely a nielanic aberration. 



The " seasonal " forms appear quite irregularly and 

 seem all to occur together at least in Anoola.
