African Species of the Genus Acraca. 125 



Underside. F.-w. resembles upperside but paler and duller. 

 H.-w. pale dull ochiemis, the marginal border formed of some- 

 what pointed black internervular arches enclosing grey spots. 

 Along the inner edge of this border a greyish suffusion. Black 

 5pot3 very small, as follows : — One in 7 about middle, one in 6 

 much nearer margin, beneath it a dot in 5, a spot near base of 4, 

 and one about middle of area 2. At about the same level 

 a double spot in Ic and one in lb. A little black at bases 

 of nervure?, a dot in 8, two in cell, and a subbasal in Ic, 

 and la. 



Head and thorax black with yellowish marks, abdomen black 

 ■at base, remainder whitish. Claws unequal. 



§ . Expanse 50-56 mm. Resembles ^ but ground-colour rather 

 more dusky. The inner edge of h.-w. marginal black markedly 

 sinuous. On underside the grey suffusion is wanting from inner 

 ■edge of marginal border, and the abdomen is whiter than in 

 the (^. 



A. omrora n.mhrata. 



(J. Expanse 46-60 mm. Extreme wet season form. Wings 

 brick red. Costa and hind, margin narrowly black. An apical 

 "black patch 3 mm. wide at broadest part. A basal black 

 suffusion which may be evenly distributed over basal area as far 

 as middle of cell or may be radiate from base. Black spots as 

 follows: — A small costal spot in area 11 at a point opposite 

 origin of uervule 2. Just beyond this in cell a large transverse 

 spot ; a small spot on upper and middle discocellulars. Beyond 

 ■end of cell in 10, 6, 5, 4, an oblique transverse row of four 

 spots which may be straight, or irregular. Three submarginal 

 spots in 5, 4, and 3, the last preceded by a subtriangular spot. 

 In area 2 a submarginal and a basal spot ; in area lb a sub- 

 marginal spot with another immediately preceding it (both these 

 may be doubled). A subbasal spot in lb more or less coalescent 

 Avith basal suffusion. In area la a small spot about 4 nim. from 

 hind angle. 



H.-w. A black basal suffusion extending to about middle of 

 cell. A black hind-marginal border about 3"5 mm. wide 

 the inner outline of which may be smoothly rounded, or the 

 border may be somewhat widened at nervules 2 and 3. lu 

 some examples this border is much wider beneath and shows 

 •through to the upperside as a grey submarginal band. In 

 most examples a submarginal row of slightly paler internervular 

 spots. Black spots less distinct than on underside, some only 

 showing through.
