African Species of the Genus Acraea. 305 



narrow hind- marginal border fading into reddish in areas lb 

 and la. A slight dusting of dark scales on the discocellulars 

 and beyond the cell, and a very small dark spot in cell, close to 

 subcostal above the origin of nervule '2. Base slightly black- 

 ened and the whole of cell, and the greater part of 2, lb and la 

 faintly powdered with red. H.-w. blackish at base, and having 

 a dark hind-marginal border as in (J . Remainder of wing 

 brick red but very thinly scaled. Black spots as in ^ but 

 those in 7, 6 and 5 beyond cell more distinct. Underside f.-w. 

 as above but almost devoid of scales except at apex and hind 

 margin where it is brownish ochreous. H.-w. base and mar- 

 ginal border brownish ochreous. Ends of nervules black with 

 short dark internervular rays which do not reach margin. 

 Central area sparsely scaled with whitish to which a pink tinge 

 is transmitted from the red scales of the upperside. 



This species is represented by a few examples kindly 

 presented to the Oxford collection by the Rev. K. St. A. 

 Rogers. It adds one more form to a very difficult 

 group, the true affinities of which are very obscure. A 

 single ^ example has just been received. The species is 

 apparently very closely allied to igola, but the h.-w. 

 spots in 7, 6, and 5 are much nearer the cell than 

 in that species. I have much pleasure in dedicating 

 it to the Rev. K. St. Aubyn Rogers, to whose skill and 

 generosity the Oxford collection owes so many vahiable 

 accessions.
