D. leucophaea Janse. Ground-colour olive-brown. Near the base 2 brown spots, the exterior spot 
incompletely edged with white. In the cell a white radial line reaching the interior white edge of the exterior 
band which is bordered by a somewhat darker shadow only outside, not inside. Submarginal line white. 
Marginal dots white, triangular, inside with a dark shadow. At the inner margin a small quadrangular white 
spot. On the hindwing a light exterior band distinct, marginal spots indistinct. S' 38 mm. Cape Colony. 
B. troglodytes Janse. Forewing reddish-brown. Near the base an oval, somewhat strangulated, 
blackish-brown spot edged with yellowish-white. The exterior band is on both sides edged with yellowish- 
white, inside somewhat broader so; it begins at vein 9, sending at vein 2 a spur to the inner margin, then towards 
the base in the middle npeurved as far as into the cell, and touching the oval spot; at its basal end dark spots 
above and below it. Before the exterior band a strong dark shadow, behind it dark spots, partly edged with 
yellowish-white. At the inner margin a white line, no spot, at the distal margin a light zigzag line. Hinclwing 
cinnamon-brown with a faint light exterior band and feeble light marginal spots. 36 mm. Cape Colony. 
The following species with a lighter, more yellowish-brown ground-colour. 
D. cretata Dist. Wings pale brown. Forewing with lactean bands. The radial band extends sharply 
angled into the exterior band which reaches only as far as the cell. £ 22 mm. It may beacrippled specimen. 
Transvaal. 
D. semicanus Janse. Forewing yellowish-brown, marking silvery white. Costal margin in the proximal 
half with white dots. A radial band below the basal half of the cell, then upeurved to the apex, interrupted 
at vein 4, besides parted by the veins 8- TO. Behind it white stripes between the veins to the margin, the 
anterior ones shorter, only forming marginal dots. Hindwing somewhat darker brown, at the margin lighter. 
£ 38 mm. Natal. 
D. ibex Wllgr. (80 e). Both wings pale brown. Forewing below the costal margin to the centre white. 
The white radial band extends with a sharp angle into the oblique exterior band. Before the distal margin 
fine white dots. Fringes of both wings lighter. — albirivula Hmps. Behind the cell before the exterior band 
fine white streaks, similar ones at the margin between veins 5 and 2. 32—34 mm. Transvaal. 
D. bacotii Quail. (80 f). As ibex, but the two bands are uniformly connected, somewhat broader and 
more faded, q 30 mm. Transvaal. 
D. isorrhoa Meyr. Anterior tibiae short, forewing longer than in the other species. The light radial 
band is narrow in the base, from the base of vein 2 irregularly undulated to the apex. Hindwing light grey, 
at the base somewhat diaphanous. $ 42 mm. Transvaal. 
D. albistriata Hmps. (80 f). Similar to semicanus . Below the costal margin a white band as in ibex. 
The two bands are silvery white, united, towards the apex broken up into spots. Marginal spots as in semicanus. 
Hindwing yellowish-brown as fore wing. $ 24 mm. Natal. 
D. leucocyma Hmps. On the forewing beside the white line below the costal margin below its end an 
oblong white streak at the upper cell-end. The radial band is divided into an oblong triangle below the base 
of the cell and a small spot above its end within the cell. Inner margin in the basal half white and above it a 
small streak at vein 1. The exterior silvery white band is narrow, undulate, from the apex to vein 2, then 
upwards and inwards farther to the end of the basal triangle. Marginal spots as in semicanus. 24 mm. Cape 
Colony. 
B. hololeuca Hmps. (80 g). Feebly yellowish brown, almost white. Costal margin of forewing brown, 
veins of a purer white, without markings. Hindwing of the same colour. Beneath both wings pale brown. - 
brunneolincta Strd. is on both wings above more intensely brown. 34- -40 mm. South Africa. 
The following species are darker, somewhat differently marked. 
D. amphiarma Meyr. Forewing dark brown. The white radial band composed of 2 irregular white 
streaks as far as the cell-end, then despatching a spur to the inner margin and straight on to the apex, on both 
sides bordered spotlike by dark. At the cell-end a white spot, above edged with dark and with white lunular 
marginal spots. Hindwing dark brown with 2 light shadows from the centre of the wing to the costal margin 
and white marginal lunae. $ 36 mm. Cape Colony. 
B. crossosema Meyr. Dark brown, only the abdominal base light. Forewing particularly dark at the 
costal margin near the base. In the cell as far as behind its centre 3 clouded dark spots, the last transverse. 
The radial band is composed of dark clouded spots, running along below the cell, at the end with a spur towards 
the inner margin, at its upper edge margined with whitish-brown; continued as an exterior band almost to 
the apex, undulate, inside light-edged. Before it 3 dark clouds near the costal margin. Fringe of both wings 
somewhat speckled. J 40 mm. Natal. 
B. rliodaula Meyr. Thorax pinkish brownish-grey. Forewing dark brown. Marking pink, edged with 
white and blackish. At the costal margin 6 or 7 round spots. A strongly bicurved line in the disc, interrupted 
in the middle and connected with the inner margin by 3 or 4 streaks. At the distal margin small spots. Fringe 
speckled pink. Hindwing grey with dark spots. Fringe also speckled. 26 mm. Cape Colony.
