H. rosae Btlr. (67 b). Antennae pink, body and forewing bluish-grey, forewing at the inner margin 
before the tornus covered with brown scales, the stigma is a brown dot. Hindwing dark grey, at the tornus 
with dark brown spots. South-West Africa. 
H. moorei Jord. differs from rosae in the absence of the white lateral stripe on the head and thorax. 
Forewing sometimes shorter, transverse lines somewhat more distinct. Hindwing pinkish brown, marginal 
area grey, at the distal margin and on the veins pink. Body silvery grey, dusted with pink. Tanganyika. — 
In canens Jord. there is no pink dusting whatever, except on the antennae. Abyssinia. 
H. rebeli R. & J. (67 b). Antennae with snow-white scales; forewing yellowish loam-coloured speckled 
with brown, likewise without complete transverse lines, with a brown spot behind the cell-end and before the 
tornus, part of a postdiscal band, and an oblique streak from the apex. Stigma small, black. Hindwing 
yellowish loam-coloured with an indistinct brown-speckled marginal band. North-East Africa. 
H. dexippus Fawc. (67 b). Similar to rosae, but the antennae bluish-grey, forewing with a curved 
median band and a more indistinct submarginal line. Hindwing ochreous, with a darker median and submarginal 
band. Keclai, East Africa. 
H. irregularis Wkr. (= crossei Rothsch.) (67 b) is the only species exhibiting a cavity at the end of the 
1st palpal joint. Forewing olive brown with more indistinct oblique lines, only the 5th being distinct by intense 
black vein-dots. Hindwing blackish-brown, at the margin lighter reddish-grey. West Africa, Uganda. 
55. Genus: Theretra Hbn. (Gnathostypsis Wllgr.). 
Second palpal joint inside with a terminal tuft which is turned downward; first joint inside at the end 
regularly densely scaled, outside with a cavity at the end. Likewise represented in the Oriental Region. 
Th. jugurtha Bsdv. (= obliterata Rothsch.) (67 c). Abdomen without lines, sometimes with a dark 
basal spot, the cavity of the 1st palpal joint sharply defined. Forewing olive green, clouded with yellowish 
ochreous, with a darker antemedian and 2 discal lines, the latter touching a submarginal line, rarely with still 
more though indistinct lines. Hindwing dark brown. West Africa. 
Th. tessmanni Gehl. (67 c). Wings light ochreous olive with 2 parallel indistinct transverse lines in the 
forewing. Fringes in the forewing brownish-pink. Cameroon. 
Th. capensis L. megara Mull., aeas Cr., cecrops Cr., immaculata Gwelin, ostracina Wallgr., octo- 
maculata Ky.) (67 c) is an easily recognizable species. Forewing green, marginal area somewhat darker, stigma 
red. Hindwing red, at the margin brownish. South and South-East Africa. Larva with an ocellus on the 4th 
segment, green or brown, with a pale stripe from the 5th segment to the horn which is short and obtuse, in 
the young larva long and S-shaped; it lives on Vitis and Cissus. 
Th. monteironis Btlr. (67 c). Similar to the following cajus; of the oblique lines the 1st and 2nd are 
almost equally strong, both in the dark oblique stripe, the line 3 is isolated, feeble, in the light stripe, 4 very 
intensely dark brown, the others feebler. Hindwing dark brown with a yellowish ochreous discal band con¬ 
taining traces of 1 or 2 transverse lines. South Africa. 
Th. cajus Cr. (= celeano Ysp., gordius Stoll, gortys Hbn., epicles Bsdv.) (67 c). In the forewing lines 
1 and 3 strong, connected by dark dusting, between them the feebler 2nd line. Line 4 feeble, situate in the 
light stripe, line 5 very strong and broad, much stronger than line 6. Hindwing in the marginal half yellowish 
ochreous, at the margin whitish with a dark submarginal and discal line. South and South-East Africa. — 
The West-African race perkeo R. <£• J. (67 d) is smaller and paler, line 5 of the forewing not stronger than 6, 
hindwing without a distinct brown discal line. — In the East-African ugandae Clark the size corresponds to 
that of perkeo, the marking to that of cajus. Hindwing unicoloured dark, only with a light submarginal line, 
forewing and the lines on the hindwing beneath darker than in both the races. 
Th. orpheus II.-S. (= natalensis Rothsch., orphaeus Dist.) (67 d). Hindwing above with 3 dark median 
lines, the cavity of the first palpal joint distinctly defined. Fore wing of a blackish-brown ground-colour, the 
pale discal oblique band indistinct and interrupted. South Africa. — The West-African pelius R. & J. (67 d) 
has narrower wings and less contrasting colours, the straw-coloured parts in the forewing are red-brown, and 
the hindwing is also red-brown instead of blackish-brown. — Darker and with broader wings than the nominate 
race is: intensa R. «£• J., but in the forewing the lines are less distinct, the oblique band behind very distinct 
and pale, but the costal margin not paler than the cell-end. Comoro Is. — The race from Southern Nigeria: 
scotinus R. <1- J. is similar to intensa ; but in the forewing the pale band extending from the centre of the inner 
margin to the apex, posteriorly whitish-grey, at about 3 mm, otherwise smoky-grey.
