ear always quite or partly yellow, deep brown, or blackish, and thereby distinctly separated from the collar 
and thoracal dorsum which are generally grey or light brown. — As to further particulars about the genus 
cf. Vol. II, p. 175, and Vol. X, p. 393. 
The numerous species form four natural groups of species. 
Table of the groups of species. 
I. The distal transverse line of the forewing is white or whitish, rarely very indistinct or yellowish or quite 
absent, invariably slanting and more or less sinuous or angular, rarely broken up in spots. 
A. Bore wing above close at the base with a white or light yellowish dot formed of hairs (not to be mistaken 
for sub basal light markings). The proximal light transverse line is generally at least indicated at 
the costal margin or hind-margin. First group of species. 
B. Fore wing without a white basal dot above. The proximal transverse line of the forewing is entirely 
absent. 
a. Forewing also without the distal transverse line. Second group of species. 
[3. Fore wing with the distal transverse line beginning at the costal margin near the apex of the forewing 
and ending in the $ only near the base of the hind-margin. Third group of species. 
II. Both the transverse lines of the forewing are distinctly blackish or grey, straight or bent, but not sinuous 
or notched. Forewing without the white basal dot, above at the hind-margin almost invariably with a 
distinctly defined longitudinal (liindmarginal) area proceeding from the base, distally pointed, of the same 
colour as the hindwing, and looking like a continuation of the costal margin of the hindwing, if the wings 
are spread out. Fourth group of species. 
First Group of Species. 
To this group belong the species being the most closely allied with T. repandum (Vol. II, pi. 29 a). They are 
distinguished by the light basal dot and the slanting, sharply sinuous transverse lines of the forewing. The proximal, often 
indistinct or interrupted transverse line of the fore wing begins a little behind the centre of the costal margin, being as far 
as vein 4 almost straight and vertical to the costal margin, then bending round towards the base, following the posterior 
edge of the discal cell as far as vein 3, whereupon it bends round almost vertically to the hind-margin. The distal transverse 
line is generally distinct and coherent as far as the posterior margin; it is almost parallel with the margin, but invariably 
forms at vein 5 an angle and extends from vein 2 straight to the hind-margin. The $$ are much smaller than the $ $, with 
narrower forewings and smaller hindwings. 
The following four species differ from the others in the two white transverse lines of the forewing above 
being thick, very sinuous and coherent or almost coherent. 
T. cristatum Cr. (32 a). Head, collar, and abdomen above grey; patagia light brown, ventrum brown cristatum. 
with whitish segmental margins. Forewing above red-brown. Hindwing somewhat lighter brown with a 
whitish median band. Fringes of both wings whitish. Cape Colony. 
T. capense Auriv. (32 a) is smaller and deviates particularly by the submarginal yellowish spots of capense. 
the fore wing and the yellow spot at the anal angle of the hindwing. Cape Colony. 
T. sodalium Auriv. Olive-grey; palpi and posterior half of patagia orange-yellow. Forewing above sodalium. 
olive-coloured, much lighter at the margin; at the base and in the centre orange-yellow; the proximal white 
transverse band is interrupted between the veins 5 and 3; the distal one is deeply sinuous. Hindwing white 
with a small dark spot at the anal angle. Both the wings beneath yellowish-white with a broad dark transverse 
band from the costal margin of the forewing to vein 5 of the hindwing. Expanse of wings: 48 mm. British 
East Africa. 
T. rangei Gaede (32 b) is very similar to T. sodalium, but it has a more monotonous and darker ground- rangei. 
colour of the upper surface of both wings and an uninterrupted proximal white transverse band of the fore wing. 
Southern Nama Land. 
The following forms are all closely allied with T. repandum Hbn. and with each other, and sometimes difficult to 
separate. They are distinguished by the white transverse lines of the forewing being always narrow and the proximal line 
always interrupted in the middle, so that it consists of two distantly separated portions, one at the costal margin between 
the costal margin and vein 5, and the other near the base between vein 2 and the hind-margin; the latter line is sometimes 
indistinct or absent. In order to elucidate the differences of the very closely allied species, it is necessary to regard the sexes 
separately. 
Table of the <$ <$. 
I. Distal margin of hindwing between the veins 2 and 7 distinctly emarginated (concave), at vein 7 and at the anal angle 
extended. 
A. Hindwing above at the costal margin and hind-margin lighter whitish, at the distal margin narrowly speckled with 
whitish-grey and with whitish fringes. T. abyssinicum.
