First Group of Species. 
Forewing above a little beyond the centre of the anal margin with a large triangular or rectangular dark brown or 
blackish-grey spot. 
T. charon Drc. B- Body light yellowish-green. Antennae light brown. Forewing light green with charon. 
a small black dot at the end of the discal cell, a feebly bent light brown transverse line near the base, a fine 
bent dentate transverse line behind the discal cell from the costal margin to the anal margin, where it 
unites with the dark anal-marginal spot, and with a submarginal row of small brown spots from the apex to 
the anal margin near the anal angle. Hindwing light green with the light brown lines continued to the hind- 
margin. Under surface very similar to the upper. — The $ is similar to the <J, but the transverse lines are 
more distinct and the submarginal dots are more feebly developed. Cameroon: Bitje. 
T. lamboumi B.-Bak. B ■ Head and thorax light green, the latter with a dark median line. Abdomen lamboumi. 
whitish. Both wings light green with olive-coloured markings. Forewing with a fine very much bent transverse 
line before the base, a dark dot in the discal cell, a feebly bent postmedian transverse line, an irregular row 
of crescentiform submarginal spots, and a triangular dark anal-marginal spot touching towards the base the 
postmedian line. Hindwing with a dark dot in the discal cell, a postmedian transverse line, and an irregular 
row of submarginal crescentiform spots. Fringes of both wings edged with light brown. The $ resembles the 
B, but it is lighter. Expanse of wings: B 48, $ 64 mm. Nigeria: Lagos. — To this species probably also belong 
some specimens lying before me from Nyassa Land and Angola. They seem only to differ in more indistinct 
transverse lines. In the $$ the forewing above exhibits a more or less distinct roundish dark spot near the 
base of area 1 b. 
Second Group of Species. 
Forewing above without a large dark anal-marginal spot. 
T. burchardi Dew. (30 a). Light greenish-yellow, hindwing at the hind-margin whitish. Dorsum burchardi. 
of thorax with a brown longitudinal band. Fore wing without a distinct basal line, at the end of the discal cell 
with a large ring-shaped discal spot filled with whitish; the dentate postmedian transverse line and the sub¬ 
marginal spots are foggy grey, partly filled with whitish, and at the anal margin a whitish-scaled spot which 
evidently corresponds to the dark anal-marginal spot of the species of the first group. Hindwing above with 
a small central dot, a dentate strongly bent transverse line, and a large grey sub marginal spot being often in 
the centre filled with white, those of the areas 4 and 5 being more remote from the margin. The margin projects 
at vein 4 somewhat more than at the other veins. Wings beneath marked almost as above. West Africa: 
C'hinchoxo and Cameroon. 
T. aethiopica Strd. (30 b). This species was described as Crinocraspeda, but it corresponds completely aethiopica. 
with the species of Trabala in the structure of the body. So far only the $ is known; it can be easily ascertained 
from the figure. Congo District: Uelleburg. 
We may append here ,,Amydona unicolor “ from Gambia having been described by Walker (1855). The brief description unicolor. 
runs as follows: „<J. Whitish with a feeble yellowish hue. Palpi blackish, below somewhat yellowish-brown. Antennae 
yellowish-brown. Legs above blackish. Length of body: 24 mm. Expanse of wings about 52 mm.“ Many years ago I had 
the chance of examining the typical specimen in the British Museum. It is almost entirely rubbed off and, regarding the 
colouring and marking of the wings, quite unserviceable. About the types I have put down the following notes: ,,Eyes bare. 
Palpi short, not projecting beyond the frontal hair. Fiscal cell of forewing closed by a fine bent cross-vein (not open, 
as Walker says). Forewing: veins 2 and 3 near together before the middle, 4 and 5 from the posterior angle of the discal 
cell, 6 and 7 forked, 8 separate, 9 and 10 on a short fork. Hindwing: veins 4 and 5 on a hort fork, 7 and 8 united near 
the base of the wing. Antennal pectinations beyond the middle the longest.” Kirby, in his Catalogue, places the species 
to the genus Phyllalia, which however is contradictory to the neuration. The species must be a Lasiocampida and may 
belong to Craspia. 
6. Genus: Closterollirlx Mab. 
Palpi small, upturned, with a knob-shaped (B) or cylindrical ($) terminal joint. Frons flat, plain. 
Eyes bare. Antennae with middling (^) or very short pectinations. Head, thorax, and abdomen with coarse, 
stiff, scrubby hams which are often thickened at the tips. Legs scantily haired; anterior tibiae unarmed; hind 
tibiae with two small terminal spurs; tarsi with appressed scales or above somewhat hairy. The neuration 
has been described above in the table of genera. Distal margin in both wings undulate or obtusely dentate. 
Hindwing beneath at the costal margin covered with coarse hair. Abdomen long, projecting far beyond the 
hindwing. The stages are unknown to me. 
C. gambeyi Mab. (B = bosei Saalm.) B • (30 a). At once discernible from the figure. $. Both wings gambeyi. 
above dark tan-coloured with black transverse lines and black submarginal spots; the discal area of both wings 
is covered with almost black, with a yellow discal spot and yellowish-brown veins of the fore wing. Both wings
