10. Family: Drepanidae. 
Whereas the Drepanidae are represented in the Indo-Australian Region by a very great number of 
species, and the palearctic fauna also contains yet a gieat many of them the family is rather scantily represented 
in Africa. Somewhat common seem to be even only 2 or 3 species, the others being smgle raiities even in large 
returns. Probably all the genera are purely African, since die species described as Drepana have no proboscis 
and retinaculum, and are thus no genuine Drepana, nor do the species described as Otroeda entirely correspond 
to the typical Indian species. All the African Drepanidae are without a proboscis and frenulum. Antennae 
and shape of wings are very variable. In the hind wing vein 8 is either very near to vein 7 behind the cell, or 
vein 7 rises at about % of the anterior edge of the ceil, separated from vein 6, and anastomoses foi 
some distance with vein 8. From similarly looking Geometridae the Drepanidae differ in the position of vein 
5, and from the partly still more similar Thyrididae in only two hindmarginal veins. 
As to further particulars, cf. Vol. III. p. 195, and Vol. X, p. 443. 
1. Genus: llranometra Bryk. 
Antennae of <$ with one row ol long pinnae. Costal margin of forewing in the apical end bent, apex 
rounded, below it the distal margin is slightly inserted. Hindwing at the anal angle rectangular, the distal 
margin behind it almost straight. Veins of forewing: vein 3 far before the angle, 4 and 5 from the lower angle, 
vein 6 from the upper angle. Veins 11 + 10 + 9 + 8 stalked, and the stalk of veins 8 + 9 forming with 7 
by a fillet the long areola. In the hindwing vein 3 far inwards, veins 4 and 5 on a short stalk, vein 6 from 
the angle, vein 7 from 3 / 4 of the anterior edge of the cell moderately long anastomosing with 8. Type: 
oculata Hold. 
U. oculata Boll. Body and antennae pale ochreous brown. Forewing ochreous-brown, at the distal ocvlala,. 
margin wine-brown. At the cell-end a fine white dot, and below the apex a small black ocellus with a yellow 
margin and around it a claret-coloured line. The lower portion of the ocellus is incomplete, terminating m 
a faded black spot. At the inner angle 2 small blackish spots. Hindwing at the costal margin whitish, otherwise 
ochreous. Under surface yellowish white, costal margin of forewing pink. 24 mm. Ogowe. 
U. diagonalis Bryk. (41 c). Similar to oculata. Body and forewing pinkish-yellow. The ocellus at diagonals. 
the apex as in oculata. Cross-vein with a white dot. From the inner edge of the ocellus to the centre of the 
hind-margin of the forewing violettish-brown. The space within this line covered with violettish-brown strigae. 
Obliquely inwards from the anal angle mostly two pale brown spots. Distal area and hindwing more lemon- 
coloured. Hinclwing also finely striated parallel to the distal margin. A violettish-brown line vertical to the 
centre of the hind-margin as far as the centre of the wing, costal margin whitish. 24 to 28 mm. Togo, Cameroon. 
Ogowe. 
U. brunneola Holt. Body above brown, beneath pink. Forewing above pinkish-brown with dark brunneola. 
striae. Subbasal line dark, uniformly curved. The apical line from the forewing to the centre of the hind-margin 
in the hindwing, on the forewing inwardly convex, at the apex double. From the cell-end to it a dark shadow 
parallel to the costal margin, and a fine notched submarginal line. Hindwing at the costal margin yellowish- 
white, otherwise pinkish-brown, also with dark striae. The transverse line widening towards the centre of the 
hind-margin and terminating in a dark brown spot which is outwardly edged with white. The same submarginal 
line as in the forewing. Both fringes dark brown. Beneath as oculata. 20 mm. Ogowe. 
2. Genus: Dl*epaillllilia Gaede (nom. nov. pro Drepanula Gaede, nec Rob.). 
Antennae bipectinate, hind tibiae with terminal spurs. Costal margin of forewing very much bent, 
apex rounded. Distal margin below it somewhat concave, then straight on to the distinct inner angle. Hindwing 
moderately stretched. Veins of forewing: veins 3, 4, and 5 rather distantly separated, vein 6 beneath the upper 
angle, 8 + 9 on a long stalk from the taperingly ending areola, 7 and 10 from % of its anterior and posterior
