R. thermochroa Hmps. (16 c) is recognisable by the yellow abdomen. Forewing brown, behind the cell thermo- 
hyaline. Hindwing intensely hyaline, margin narrowly pale brown. 46 mm. East Africa. 
R. phaedra Weym. (16 c). Forewing only at the cross-vein somewhat hyaline, otherwise brown, phaedra. 
Hindwing orange-brown, rather round. 42 to 55 mm. East Africa. 
R. madagascariensis Mob. (= vitripennis Blch.) has the size and colouring of bauri (16 c). The hyaline madagasca- 
area of the forewing is not margined with dark. Hindwing somewhat less hyaline, in the proximal area pink. riensis. 
62 to 65 mm. Natal, Madagascar. 
R. bauri M.schlr. (16 c). Abdomen pale yellowish-pink. Forewing pale brown. In and behind the bauri. 
cell hyaline. Hyaline area below vein 5 distally projecting, distally bordered with dark. Hindwing pale brown, 
semi-transparent. All around the margin more densely scaled. 58 to 65 mm. South West Africa, Transvaal, 
Natal. 
R. saalmiilleri Rothsch. (= vidua Saalm.) (16 d) resembles a small bauri. Abdomen above more saalmulleri. 
intensely red, beneath purely white. 40 to 45 mm. Madagascar. 
R. vitrea Plotz (16 e). Thorax and forewing somewhat darker brown. Forewing just as intensely vitrea. 
hyaline as saalmulleri, cross-vein only narrowly brown. Hindwing almost quite hyaline, only at the margin 
narrowly scaled. 46 to 50 mm. Sierra Leone, Niger District, South Africa. 
R. affinis Rothsch. (16 e). The light area in the forewing does not extend so far towards the base in affinis. 
the cell. Hindwing at the apex broadly brown, then very narrowly onward, otherwise almost entirely diaphanous. 
52 mm. Natal. 
The following species more or less white. 
R. aldabrensis Fryer (13 i). Thorax chalky white, abdomen above carmine. Forewing white, with aldabrensis. 
a brown hue, only at the margins more intensely powdered. An apical spot as far as vein 4 smoky brown. 
Hindwing white, semi-transparent. 40 mm. Seychelle Is. 
R. nigroapicalis Aur. (16 d). Larger, of a purer white. Forewing with a smoky brown apical area nigroapica- 
narrowly extending almost to the anal angle. Hindwing at the apex somewhat smoky brown, below vein 2 
pinkish-white. In specimens from Fernando Po the hindwing is not brown. In all the specimens the hindwing 
lacks vein 4. 56 to 62 mm. Cameroon, Fernando Po. * 
R. fuscivena Hmps. (16 e). Thorax and abdomen yellowish-white, the latter at the end pink. Wings fuscivena. 
brownish-white. Veins of forewing blackish-brown. 52 mm. Uganda. 
R. nigrivenosa Griinb. (16 f) is separated by the purely white ground-colour of the wings being uniformly nigrivenosa. 
slightly diaphanous. Veins of forewing blackish-brown. Abdomen above quite red, beneath white. 52 mm. 
Central Africa. 
R. leucoptera Hmps. (16 e). Thorax and abdomen at the base white, the rest above carmine. Wings leucoptera. 
white, semi-transparent. 52 mm. Sierra Leone. — In subleucoptera Strd. from East Africa the hindwing is subleuco- 
somewliat pink at the hind-margin. ptera. 
R. niveivitrea Brtl. (= subleucoptera Strd.) (16 d) is just as large and very similar to leucoptera. On niveivitrea. 
the fore wing a more densely scaled white distal area is similarly defined as in the brown species (for instance 
bauri , saalmulleri). 52 mm. Cameroon. -— In all the specimens of niveivitrea vein 4 of the hindwing is absent, 
which intimates an alliance with nigroapicalis. Maybe that niveivitrea is merely a not dark-margined nigroapicalis. 
Group III. $ with a small hair-pencil between the antennae. 
On the forewing at the base of the costal margin somewhat inflated. All the spe¬ 
cies are white. 
R. bubo Wkr. (16 d). Thorax yellowish-white, abdomen above yellow. Wings white. Forewing from bubo. 
the cell-end to the apex somewhat hyaline. 60 mm. East, Central, and West Africa. 
R. atrivena Hmps. (16 f). Abdomen also above white. Veins of forewing blackish-brown. 58 mm. atrivena. 
Uganda. 
R„ rufifemur Wkr. (16 f). Smaller. Thorax slightly yellowish. Abdomen white with 2 lateral rows rufifemur. 
of black dots. Hind wing somewhat hyaline. 48 mm. Congo. 
R. lupia Drc. (= nivaria Weym.) (16 e). White, feebly lined with yellowish. Abdomen above in lupia. 
the centre pink. Forewing on the subcostal veins and vein 2 finely black, with a transparent streak at the 
cross-vein. Both wings at the margins more densely scaled, in the centre somewhat diaphanous. ■— In sanguinota 
Strd. the abdomen is red as far as the end, otherwise not different. — 38 to 42 mm. East Africa, Transvaal. 
R. magnifica Rothsch. (16 d). Abdomen above in the terminal half carmine. Forewing with black magnifica. 
basal dots and a pale brown band from the centre of the costal margin to the anal angle. The distal part 
oi the costal margin, and the distal margin as far as vein 4 are pale brown. The enclosed space is somewhat 
diaphanous. Hindwing white, at the cell-end and behind it somewhat hyaline. 74 mm. East Africa.
