those of aethiops, 10—12 mm long, almost quadrangular, in front quickly widening, clothed with transverse 
short branchlets and ribs of leaves. On Brachylaena discolor. 
In the following species we cannot gather from the authors’ statements to which subgenus of Psyche they belong and 
with which other species described they may be identical. 
Ps. vuilleti Obth. (72 i). Body greyish-brown. Wings hyaline, only at the inner margin of the hindwing 
with greyish-brown hair. 20 mm. Senegal. Larva on Acacia fasciculata. The sac is covered with tiny pieces 
of leaves; 25 mm long, 10 mm thick, pointed at both its ends. (See also p. 485 above at brunnescens.) 
Ps. joannis Obth. (72 i). Body blackish-brown. Wings quite hyaline. 25 mm. Niger. Larva on the 
Combretacea Guierra senegalensis. The sac is about 30 mm long, 10 mm thick, according to Oberthur’s figure 
covered with uncommonly large pieces of leaves. 
? Ps. joannisii Mab. (72 i). Contours like a species of Oeceticus, but placed to the genus Psyche by the 
author. Ashy brown, at the base lighter. The costal margin of the forewing at the base slightly concave. 
32 mm. Madagascar. Not recognizable from this description, perhaps identical with Deborrea malgassa. 
Subgenus: Heylertsia Pimps. 
In the forewing veins 4 and 5 not stalked, vein 6 present, but in the hindwing absent. Type: griseata Hmps. from Ceylon. 
Ps. calamachroa Hmps. Monotonously pale ochreous brown, antennae somewhat darker. 20 mm. 
East Africa. 
6. Genus: Apterona Mill. 
As to the European forms we l’efer to Vol. II, p. 363. In Africa only the sac of a species resembling the 
European A. helix was found. 
A. valvata Gerst. The sac has S 1 /? torsions, it may be wound to the right or left. Largest height and 
width each 10—11 mm. Colour earth-brown. East Africa. 
3. Subfamily: Chaliinae 
In the f o r e w i n g from lb and 1 c no branch to the inner margin. Hind 
tibiae without spurs. 
7. Genus: Clialia Mr. 
Antennal pectinations decreasing in length towards the tips. Anterior tibia with a long spine. Wings 
broad. In the forewdng all the veins are present, in the hindwing veins 5 and 8 are absent. Type: doiibledayi 
Ww. from Ceylon. 
Ch. emiliae Heyl. (72 h). Body ochreous. Wings blackish-brown. Neuration rather variable. In the 
forewing veins 4 + 5 not always stalked, 9+8 may have a long stalk and 7 may branch off at the lower end. 
or vein 7 is free and only 8+9 are stalked. Vein 6 always absent. 22 -24 mm. Delagoa Bay. The sac is 
covered with grey or brick-red sand, 35 -55 mm long, 7- 10 mm thick. 
Cli. salae Heyl. Only the casing was described. Kirby placed it here, whereas the author denotes it 
to be an Eumeta ( ?). The sac has a diameter of 15 mm, a length of 43 mm, and it is regularly covered with 
branchlets of the same length, out of which the cocoon projects as in Cl. moddermanni. 
Ch. maledicta Scheben is likewise described only after the larval sac which is 27 -52 mm long, conical, 
at the end 5 to 6 mm thick, covered with grey or yellow sand and with tiny pieces of bark. The only dark 
imago bred escaped. South-West Africa. 
Ch. miinzneri Strd. Described after two sacs of hardly full-grown larvae. 16 mm long, 4 mm thick, 
of dark brown silk, densely clad with long grass-awns. East Africa. 
4. Subfamily: Psychoitlinae. 
In the forewing veins lb and 1 c not anastomosing in the typical 
genera, w' i t h o u t a branch to the inner m a r g i n. Hind t i b i a with one p a i r 
of spur s. 
8. Genus: Monda Whr. 
Body very weak. Hind tibia with a feeble pair of spurs. Fore wing without veins 7 and 10, hindwing 
without vein 6. Wings white or transparent. Type: delicatissima Wkr. 
M. delicatissima Wkr. (72 i). Forewing from the apex to vein 4 and a little into the cell, as well as at 
the costal margin blackish-brown. Above and below vein 3 a feeble black spot, all the rest white hyaline. 
24 mm. Cape Colony, Natal. Larva on Desmonodium iucanum. Sac 12 mm long, a “wandering four-sided 
pagoda”.
