and 2 before the centre. Hindwing: vein 5 developed, and 2 and 3 nearing each other. The scales on the under 
surface of the wings, particularly of the hindwing and on the ventrum of an uncommon size. Hind tibiae shorter 
than the tarsi with abundant soft hairing and a pair of terminal spurs.“ The forewing in all the species shows 
above a yellow spot in 1 b, and 6 or 7 hyaline spots (two in the apex of the discal cell, a larger one in 2, a 
small one close at the base of area 3 and one little dot each in 6, 7 and 8). Hindwing above uni-coloured without 
markings.

or blackish-brown ground-colour; forewing beneath at the costal margin and in the apical part light ferruginous, 
behind it blackish and between vein 4 and the apex with a row of dark spots which may also be united forming 
a submarginal band; hyaline spots as above, the dot in 8 often absent. Hindwing beneath light ferruginous 
or yellowish-brown; a postdiscal, darker, sometimes indistinct transverse band proceeds from vein 1 b, extends 
towards the apex of the wing and gradually tapers off; more or less distinct dark spots occur besides in the 
basal part and at the margin. In all the specimens before me (3 $$) the hind tibiae have 4 spurs. Mabille’s 
statement is probably due to an error in the observation. Angola, Rhodesia, ,,Caffraria“, Nyassa Land, 
Kilimandjaro. 
Ch. telisignata Btlr. is above very much like the preceding species and only differs by its darker blackish telisignata. 
ground-colour and larger hyaline spots of the forewing, beneath it is also much darker coloured and distinguished 
by the hindwing showing in the centre a sharply defined white spot or transverse band. Palpi as well as 
front tibiae and front tarsi partly white; thorax blackish; ventrum densely clothed with grey hair; anal pencil 
whitish. Expanse of wings: 32 mm. Nyassa Land and British East Africa. 
6. Genus: Ciamia Holl. 
Large, variegated species distinguished by the strong, almost straightly porrect palpi. Frons right 
behind the palpi with a transverse band of erect scales. Margin of forewing in the centre bent, hindwing with 
a distinct anal lobe. Vein 2 of the forewing rises a little before the centre of the cell, that of the hindwing behind 
the centre. Vein 5 of the hindwing well developed. Spiral tongue very long. Hind tibiae with 4 spurs. Eorewing 
with large hyaline spots; hindwing above with a transverse row of yellow spots. 
The forms known hitherto have the following marking's in common: forewing above in lb at the submedian with 
two spots, a yellow one before the centre and a yellowish hyaline spot a little behind the centre, in 2 with a large, oblong, 
yellow hyaline spot which, however, does not cover the base of the area; in the discal cell with a similar spot beginning nearer 
at the base, but not reaching to the apex of the cell; in 3 with a much smaller and somewhat lighter hyaline spot near 
the centre of the area, and before the apex of the wing in the areas 6 to 8 with three small whitish hyaline spots in a slanting 
transverse row, the spot in 6 being the largest. The-under surface of the forewing differs by the proximal margin being almost 
quite yellow in la and lb, the number of the subapical hyaline spots being four, since there is also in 9 such a spot, the 
costal margin being at the base and in the centre more or less brightened up, and by the areas 4 to 7 being decorated with 
rounded dark brown marginal spots. The hindwing exhibits above a yellow-haired longitudinal spot in the discal cell and behind 
the centre a transverse row of 4 or 5 small yellow spots (in lb to 5). Beneath these spots are less distinctly ferruginous- 
brown or greenish. Fringes dark brown, between the anal angle and vein 2 of the forewing and between the anal angle and 
almost to vein 2 of the hindwing yellowish. 
G. galua IIoll. (= ditissimus Mob., zintgraffi Karsch ) (79 h). Hindwing beneath with blackish-brown, galua. 
ferruginous-brown and grey markings without green spots. 
G. buchholzi Plotz (80 g). $. Hindwing beneath with greenish discal spots and a thick greenish buchholzi. 
longitudinal streak in the discal cell. Our figure is a copy of the original figure by Plotz. The $ is unknown, 
and I do not possess sufficient material for stating any other differences between the two species. — basistriga basistriga. 
Holl. which the author himself unites with buchholzi, seems to me to agree better with galua. Both the species 
exhibit at the base of the hindwing beneath a more or less distinct white transverse streak. Gold Coast: Aburi. 
7. Genus: Pteroteinoii Wts. 
Discal cell of the forewing long, attaining about two thirds of the forewing. Vein 5 of the forewing rises 
before the centre of the cell. Vein 5 of the hindwing distinct. Hind tibiae hairy with 4 spurs. 
Pt. laufella Hew. (80 g). Wings above dark brown, forewing almost entirely, hindwing at the margin laufcUa. 
broadly covered with a dark blue or green reflection, veins of a darker colour. Eorewing beneath at the posterior 
margin in 1 a and 1 b brown, in the discal cell and in the basal part of the areas 2 and. 3 with a bluish or 
greenish reflection, then lighter brown with dark veins. Hindwing beneath light greenish with dark veins. 
Abdomen beneath at the apex haired reddish-yellow. Gold Coast to Congo, Madagascar (?).
