African Species of the Genus Aeraca. 85 



at apex and increasing in size towards hind angle. Black spots 

 (obscured by ground-colour) as follows. In cell one small spot 

 at base (usually almost lost in basal suffusion), a larger subbasal 

 spot, a still larger transverse spot between the latter and end of 

 cell, and a transverse spot on the discocellulars. A transverse 

 discal band of large confluent spots from costa almost to nervule 

 3, the area between this and apical black distinctly paler and 

 in many cases white or yellowish. In area 2 a large spot below 

 origin of nervule 3. Below this, in area lb but nearer margin, 

 a large reniform spot. Near base of same area and close to 

 median, a small spot. Areas la, 11), and 2 usually with a slight 

 central red sufl'usion. 



H.-w. vermilion red. A heavy black basal suffusion reaching 

 nearly to end of cell, and a black marginal border about 3 mm. 

 wide, (its inner edge not very sharply defined,) and bearing 

 seven small internervular spots of the ground-colour. Black 

 spots as on underside, those nearer base being lost in the basal 

 suffusion. 



Underside. F.-w. Basal and discal portion dull pink. Costa 

 dull ochreous, black at base, and with a minute black subbasal 

 spot. A slight black suffusion at base of area la, and lb. Other 

 spots as on upperside. Apical and hind marginal black largely 

 displaced by orange ochreous internervular spots which are 

 larger and more distinct than on upperside. H.-w. dull creamy 

 ochreous, the black marginal border more sharply defined, 

 bearing seven subtriangular spots of the ground-colour (that in 

 Ic doubled) and bordered on its inner edge by seven corre- 

 sponding red spots. Nine discal black spots those in 7, 6, 5, 4, 

 and 3 roughly parallel to margin, one at origin of 5, one in 2 

 between 2 and median, one in Ic, rather nearer margin, and one 

 in lb, on a level with that in 2. A small spot in 8 above 

 precostal. A black basal patch of confluent spots bordered 

 outwardly with rose pink and enclosing six pale ochreous mark- 

 ings, one in 7, two in cell, and one in Ic, lb, and la respectively. 

 Area 9 and basal part of 8 rose pink. 



Head black with a white spot between the eyes. Thorax black 

 with Avhitish lateral spots more numerous beneath. Basal half 

 of abdomen black, remainder deep orange, with a terminal 

 fringe of black hairs. Claws unequal. 



5 . Expanse 80-95 mm. F.-w. varying from dull reddish to 

 brownish grey. Spots as in ^ but much less distinct, and apical 

 and hind marginal black paler and more suffused. An oblique 

 subapical white bar from near costa to nervule 4. H.-w. dull 

 reddish brown, with blackish marginal border bearing spots of
