African Specicb of the Genus Acraea. 335 



The underside corresponds to the upper in the same way as 

 in typical examples. 



I have seen only one example of this form, viz. the type, 

 though in the collection of Mr. C. J. Grist there is au 

 example which comes very near it in pattern, but the f.-w. 

 subapical bar is pale tawny instead of white. 



A. esehria mamris, subsp. 



This island form of esebria is characterised by its smaller 

 average size, the ^ being about 50 mm. and the 9 about 56 

 mm. in expanse, and by the larger size of the pale sjjot in f.-w. 

 area 2. The wings are somewhat more rounded than in the 

 type form. The ^ has the f.-w. black brown with a rather 

 narrow subapical band varying in colour from ochreous to 

 orange, and a narrow inner marginal patch of the same colour. 

 The h.-w. has a dark grey basal area extending to about the 

 middle of cell, followed by an orange or ochreous central band 

 and a broad black brown hind-marginal border usually well 

 defined inwardly. 



The 9 presents the same pattern but the f.-w. subapical 

 band is somewhat broader, and the paler markings may be 

 either orange ochreous or white. 



'o^ 



This form may usually be recognised by the much 

 larger pale spot in f.-w. area 2, but though specimens have 

 a generally different appearance from those taken on the 

 mainland it is difficult to point out a really constant 

 difference. 



The larva of A. esebria is described by Trimen as 

 follows : — 



" About 1 J in. long Pale ochreous brown; each segment 

 (except head, and segment next to it) banded transversely and 

 centrally with a black streak edged on both sides with a pale 

 yellow streak. A lateral stripe of the same pale yellow. Head 

 black. Second, twelfth, and thirteenth segments each with two 

 black spines ; third and fourth segments each with two pairs 

 of black spines, each of the remaining segments with four black 

 spines springing from central black streak, and two lateral pale 

 yellow spines. On a species of Fleurya, in February and March." 



The same author thus describes the pupa : — 



"About I in. long. Chalky white with a faint yellowish 

 tinge. A series of very line linear black markings along dorso- 

 thoracic ridge. Antennae and wing-nervures faintly indicated
