African SjMcies of the Genus Acraea. 39 



forms in which it is not so, then the f.-w. subapical patch 

 is very narrow, rarely exceeding about 3-5 mm. in width. 

 Border in h.-w. never so broad as almost to reach end 



of cell esebria* (331) 



H.-w. dark border if present is not sharply defined inwardly 

 except in forms in which it is so broad as almost to touch 

 cell, and in such cases the f.-w. subapical patch is much 

 more than 3-5 mm. in width .... jodutta * (327) 

 (r) F.-w. perfectly transparent and scaleless except for a narrow, 

 intensely black apical and hind marginal border and a very 



little black at base seinivitrea (300) 



F.-w. not as above . , . . . . . • (s) 



(s) H.-w. cell beneath with not more than one spot . . . (i) 



[Some examples of lycoa have a second spot in cell, but this is 



usually accompanied by a blackish streak. Or the streak 



may be broken up giving the appearance of several spots.] 



H.-w. cell beneath with more than one spot . . . (w 



{t) F.-w. with a subapical patch of three elongated transparent 



spots servona (part) (292) 



[A. servona nearly always has more than one spot in cell. See 



under (w).'\ 

 F.-w. without such subapical transparent patch . . . (m) 

 (h) H.-w. beneath with a narrow elongated central yellow patch 

 and an inner marginal red brown patch . oreas (298) 



H.-w. beneath not so marked (u) 



(v) Distal outline of h.-w. pale patch has a tendency to be angulated 



at area 4, giving the patch a somewhat quadrate appearance. 



This angulation is most easily seen beneath johnstoni (339) 



[A. johnstoni is polymorphic. For forms see descriptive section.] 



Distal outline of h.-w. pale patch is regularly rounded 



lycoa (part) (336) 

 [A. lycoa is also polymorphic. See descriptions.] 

 {iv) Both wings fully scaled without any partially or wholly trans- 

 parent patches or spots . . . . . . . (x) 



Transparent or partially transparent areas in one or both wings (z) 



(x) F.-w. without any red or orange marks . lycoa (part) (336) 



F.-w. with red or orange marks ...... (y) 



(y) F.-tv. vnth elongated red patches between the nervides . . (1) 



(1) H.-w. discal spots large and forming a band which extends well 



beyond cell ..... orina orina (263) 



H.-w. discal spots not extending well beyond cell . . • (2) 



* For the various named forms of esebria and jodutta see descrip- 

 tive portion. It is scarcely possible to give concise characters which 

 constantly differentiate between them, and some little experience is 

 required befi^re the two .species can be separated at sight.
