present in the cotype and not in the tyj e ; ii) 4 a spot near 

 margin immediately beneath that in 6, a spot in 3 not quite 

 touching end of cell, one in 2 touching median and nervule 2, 

 a laige transverse spot in Ic, nearer to margin, and one in lb 

 and la nearer to base. In addition to these, a spot in 8 slightly 

 removed from precostal, a siibbasal in 7, two in cell, one at base 

 of 5 touching m.d.c, a transverse subbasal spot in Ic and la, 

 and between these, but more distally placed, a small spot in lb. 



Head and thorax black, latter with a few brown hairs, 

 abdomen black with the last two or three segments orange. 

 Claws unequal.

There are at present only two examples of this Acraea, 

 the type in the National Collection and the cotype 

 at Oxford. Both were taken by Neave on the Lualaba 

 River, Belgian Congo. It is distinguishable from small 

 examples of A. acrita by the f.-w. discal spots, and from 

 acrita manca by the broad black apical patch. 



The genital armature is very distinct. The claspers are 

 entirely different from those of acrita, or indeed of any 

 other species I have examined. The true uncus is reduced 

 to a mere bristle, whilst the chitinous sheath of the penis 

 is developed into what appears to be a false uncus.

9. Expanse 48-56 mm. F.-w. translucent and having a 

 milky appearance, being sparsely covered with greyish white 

 scales, and for a depth of about 6 mm. the aj^ex is somewhat 

 dusky, the nervules and rays being a little darker. There is a 

 trace of a dark spot in the middle of cell, and another in 2 just 

 under median. In lb a third much nearer margin. H.-w. 

 rather more thickly scaled dusky white, with a blackish mar- 

 ginal line and internervular arches, the latter inwardly suffused. 

 The spots of the underside show through. 



Underside, f.-w. almost scaleless, h.-w. dusky greyish with 

 rather thick well-marked black marginal arches enclosing spots
