African Species of the Genus Acraea. 205 



H.-w. with a little black at base and a hind-marginal black 

 horder about TS mm. wide the inner edge of which may be fairly 

 regular or may be indented between the nervules by the 

 ground-colour. Black spots corresponding to those on the under- 

 side. 



Underside. F.-w. ground-colour paler than above. Costa 

 greyish white, the apical and hind-marginal areas striated by 

 the black ends of nervules wiiich are laterally dusted with 

 white, a fine black line round margin. 



H.-w. brick red, all the spots more or less surrounded with 

 white, the black ends of nervules laterally dusted with white. 

 A fine black marginal line on which at the end of each nervule 

 stands a black V-shaped mark with its apex on the margin, the 

 spaces between these markings being white. The costa is also 

 narrowly white. The proportion between red and white varies, 

 and someexamples mightbe described as having the ground-colour 

 whitish with broad internervular red marks. Small black spots 

 as follows : — A discal row of nine, the first four, in 7, 6, 5, and 

 4 forming a line parallel to the apical margin of the wing, the 

 line then curving round so that the next four lie on a line at 

 right angles to the inner margin ; the last in la is rather nearer 

 base. Some irregular black marks at base of wing. A spot in 

 8 against the precostal, near it one in 7, two in cell and one at 

 base of 5 and 4 on discocellulars, one in Ic and lb close together, 

 and a basal spot in la. 



Head and thorax black, brown tufts on collar. Abdomen 

 black above with reddish yellow lateral spots. Claws unequal. 

 9 . Like the ^ but somewhat larger. 



Up to the present I have not seen a $ of this species 

 resembling the ^ in colour, but Aurivillius states {I.e.) 

 that such $ ^ exist, and these niust therefore be associated 

 with the $ type. 



A. zitja f. radiata. 



$ $ of this form have a brownish ground-colour and the 

 spots are more prominent. In the f.-w. the space between the 

 discal spots and the hind margin is somewhat paler than the rest, 

 whilst there is a pale curved discal band just beyond the discal 

 spots in the h.-w. Mabille {I. c.) figures the underside of a (^ 

 which he assigns to this form, and in this there is a pale area in 

 f.-w. beyond the discal spots 6, 5, and 4, and in the h.-w. there 

 is much less internervular red than usual beyond the discal 

 spots, also rather less marginal white. He states that inter- 

 mediates are numerous.
