African Species of the Genus Acraea. 287 



lemon ochreous beginning in area 6 and ending in lb, its inner 

 edge edentate in cell, and its outer edge edentate between the 

 nervules especially in 6, 5 and 4. 



Underside, F.-w. Costa, apical area, and hind margin 

 dusky brown ochreous, striated by the black nervules, which 

 join in a fine marginal line. In areas 6-2 short black inter- 

 nervi;lar rays beginning at inner edge of the yellow colour 

 and rapidly diminishing to a point some distance short of the 

 margin. Remainder of wing rather thinly scaled with black 

 except in way of transparent spots, these having a slight 

 dusting of yellowish white scales as on upperside. 



H.-w. lemon ochreous with a greenish tint at base and over 

 outer marginal border. On the latter the nervule ends are 

 rather broadly black and join a fine marginal black line. 

 Between them are short black internervular marks separated 

 from margin by a distance about equal to their own length. 

 Black spots as follows : — One in 9 at base, two in 7 occasionally 

 coalescent, one at base of area 6 (rarely absent), two on disco- 

 cellulars (these, and that in 6, often confluent). One in cell 

 near base. A large crescentic spot in Ic (rarely divided into 

 two). Two in lb (sometimes coalescent), a basal linear mark 

 in the same area, and two spots in la. 



In one ( $ ) example before me the internervular marks are 

 inwardly confluent with the black powdering of the nervules. 



Head black with a white dot between eyes and two on collar. 

 Thorax black with some yellowish dorsal and lateral spots. 

 Abdomen black with yellowish lateral spots. Claws equal. 



$ . Expanse 52-54 mm. Resembles ^^ but the transparent 

 spots, especially the subapical series tend to be larger, except 

 that in lb, which is sometimes wanting. The h.-w. patch is, 

 in one example, white. 



A. mairessei f. dewitzi. 



F.-w. thinly scaled with black. The transparent s^ot in 

 cell is reduced to a mere streak, as also is that in lb. The 

 h.-w. patch is tawny red, and reaches the costa and inner 

 margin. The underside is like that of the typical form but 

 the yellow areas are of a more golden tint, and the inter- 

 nervular marks are rather more slender. They are not 

 proximally confluent with the black of the nervules. 



The example above referred to was described by Dewitz 

 as a variety of A. peneleos. Aurivillius has pointed out 

 (l. c.) that it appears to be a red form of his mairessei,
