hind-marginal clouding is of a fainter blackish. UNDER- 

 SIDE, Closely resembles that of $ , but universally paler. 

 Fore-wing: pale-yellowish colouring of apical portion ex- 

 tending along costa, and sometimes forming a narrow edging 

 as far as anal angle ; the ochreous inter-nervular rays fainter 

 than in $ . Hind-wing : hind-marginal, inter-nervular, red- 

 dish-ochreous markings ill-defined, the three next costa 

 obsolete ; blackish streak wider than in $ . 



Marshes, and damp, low-lying fields ; rarely in gardens.

Though local in its haunts, this pretty little Acraa is very abundant 

 where it occurs. Its flight is slow and gentle, with a whirring action of 

 the wings, and a tendency to assume a circular direction. It keeps always 

 near the ground, generally delighting in the dense reed-beds fringing river- 

 banks, where it very frequently settles on the flowers of marsh-loving; 

 plants. The abundance of this Butterfly in the marshes bordering the 

 little river Bitouw at Plettenberg Bay, in the beginning of February, 1859, 

 was really wonderful to witness. I know of no Rhopalocerous Insect more 

 easily captured than this species. There seems to be, as noted above, two 

 distinct broods of this Butterfly in the year ; a marked interval of about 

 two months occuring during my stay at the Knysna, when I did not notice 

 a single individual of this species. The $ A. Rahira is considerably 

 larger than the $ . M. Boisduval writes, in the " Faune Entomologique 

 de Madagascar, fee.," that M. Goudot stated his having taken this species 

 at Tamatave, on the East coast of Madagascar, but that as he (M. B ) 

 possessed the insect from the " pays des Hottentots," he fears that M. 

 Goudot must have obtained it at the Cape of Good Hope, and confounded 

 it with his Madagascar captures. I do not see any necessity for this doubt, 

 so many species of Butterflies being common to both Madagascar and the 

 main land of Africa.

Pale yellow -ochreous, semi-transparent ; thickly spotted
