African Species of the Genus Acraea. 339 



$ and ochreoiis in ^. H.-w. patch rather larger than in 

 previous forms and sharply defined. 



A. lycoa kenia, subsp. 



Both sexes smaller than in other forms. Ground-colour 

 nearly black. H.-w. patch slighly edentate between nervules 

 3 and 4. Dark areas on underside smoky black. ^ with 

 spots and h.-w. patch lemon ochreous. J h.-w. patch lemon 

 ochreous, f.-w. spots white. 

 A. lycoa aeqnalis, subsp. 



The sexes are similar. The f.-w. spots and h.-w. patch dull 

 ochreous. H.-w. marginal border inclined to tawny. 



The larva and pupa are described by Aurivillius (/. c.) the 

 former being yellowish without markings and having a black 

 head and black spines, the latter scarcely as long as the 

 diameter of the body. 



The pupa has the usual black markings, those of the abdo- 

 men enclosing pale centres and being irregularly angulated. 

 Segments 2-4 each have a pair of short black dorsal spines, 

 yellowish at their bases. 



On PI. VI, f. 8, I have figured an example of the larva 

 taken by Mr. Lamborn near Lagos. 



I have already (Trans. Ent. Soc, 1911) discussed at 

 some length the variation ^vhich occurs in this species 

 coincident with its geographical distribution. The depth 

 of colour increases as we pass eastwards, whilst it is a 

 remarkable fact that it exhibits constant sexual dimorphism 

 until it reaches Abyssinia, where the $ becomes yellow 

 spotted in the f-w. as in the ^. Forms intermediate 

 between those here described are of course found on the 

 overlapping areas of the districts to which each form 

 is peculiar, but within those districts the forms are very 

 constant. The species has lately been bred in very large 

 numbers by Mr. W. A. Lamborn near Lagos. • These 

 series are now in the Oxford collection and show little or 

 no variation.
