B. continua Auriv. Costal region of forewing sometimes darkened by blackish lines. The transverse 
lines of the forewing are dark brownish-grey and coherent or only interrupted by the white veins; the postdiscal 
line is directed towards the apex of vein 8 and almost quite straight; the submarginal line is often indistinct. 
Costal margin of forewing narrowly ochreous-yellow. Antennal shaft white, pectinations yellow. Palpi ochreous- 
yellow, outwards black. Body and wings white, or in the $ grey; veins of forewing white, lighter than the 
ground-colour. German East Africa. Uganda. — niphoessa Strd. (30 d) only differs in its somewhat smaller 
size and in the absence of the submarginal line of the fore wing. Mkalamu. Sudan. 
B. bistrigata Strd. (30 d) differs from the species mentioned last, as the figure shows, only in both 
the transverse bands being distinct and almost straight, and particularly in the postdiscal band being directed 
towards the apex of the wing. The ground-colour is whitish-grey. Mkalamu. — canofusca Strd. (30 d) I can 
only regard as a dark form of bistrigata. German East Africa. — senegalensis Oberth. is probably also only a 
dark $ of bistrigata. Senegal. 
B. pura Warr. & Rothsch. (30 e). In the the wings and body are of a pure white. Antennae and 
palpi yellow, the latter outwards blackish. Costal margin of forewing narrowly ochreous-yellow. Forewing 
above only with a postdiscal line which is indistinct and directed towards the apex of the wing. It is similar 
to B. niphoessa (32 d), but larger (expanse of wings: 40 mm) and deviates by the postdiscal line directed towards 
the apex of the wing. Sudan. 
B. pulla Strd. (30 c). A small (expanse 23 to 24 mm) brownish-grey species in which, as in all the 
preceding species, the costal margin of the forewing is narrowly ochreous-yellowish. Under surface uni-coloured, 
of a colour like the hindwing above. Antennae light brown, at the base with a small light ochreous-yellowish 
hair-tuft. Palpi ochreous-yellow, outside with black hair. East Africa: Yringa District. 
The two following species differ from all the preceding species in the costal margin of the forewing and the palpi not 
being coloured yellow. 
B. wallengreni Auriv. (= obliquata Wallengr.) (30 e). A. Body, wings, palpi, antennal shaft and 
legs white or whitish; palpi outside brownish, antennal pinnae light yellowish; tarsi with black rings. Eorewing 
elongate, postdiscal line cpiite straight, light brownish, coherent, beginning close at the base of the forewing 
and terminating at the apex of vein 8; it is thereby almost quite parallel with the costal margin; the submarginal 
line is very indistinct. $ unknown. Damara Land: Kuisip River. 
B. bettoni Auriv. (30 e). Body, hindwing above and beneath, as well as forewing beneath, blackish- 
grey without markings. Forewing above dark grey with somewhat lighter veins, a blackish longitudinal streak 
in the discal cell and blackish transverse bands, the first of which is broad and extends from the centre of the 
anal margin to the apex of the wing; the second extends along the distal margin and is composed of roundish 
spots. British East Africa. 
Second Group of Species. 
The few species of this group differ from the forms of the first group in the uni-coloured, not black-ringed tarsi, 
and from those of the third group in the absence of the white discal spot of the forewing. The species are very different 
from each other and hardly more closely allied. The first species approximates B. wallengreni by the colour and marking 
of the forewing, and the two others deviate from all the other species of Beralade in the discal area being on both sides bordered 
by almost erect transverse lines. 
B. signinervis Strd. <$. ,,Forewing dark greyish-brown with a yellowish reflection and a blackish 
longitudinal streak extending sub parallel to the costal margin, beginning on the apex of vein 8 and extending 
towards the base of the anal margin which, however, it does not quite reach; behind this band there is an 
indistinct dark line parallel to it. Costal margin straw-coloured. Fringes at the ends white, of a silvery lustre, 
at the base greyish. From the base through the cell a darker indistinct stripe. Hindwing grey with a feeble 
brownish hue; fringes as in the fore wing. Marginal line in both wings hardly traceable. Under surface dark grey, 
in the forewing with lighter veins. Body above like the hindwing, head in front very slightly brownish. Antennal 
shaft whitish, pinnae brownish. Palpi yellowish. At the interior margins of the eyes there are black hairs. 
Expanse of wings: 23 mm. The $ is larger (about 28 mm) and lighter. Forewing straw-coloured; the posterior 
dark band is rather distinct and almost as broad as the anterior band. Hindwing pale straw-coloured. Antennae 
and palpi yolk-coloured. ,,The species is particularly distinguished by the dark longitudinal line extending 
from the base of the fore wing to the postdiscal line. In the specimens I have seen this line was quite distinct. 
B. simplex Auriv. (30 d), as the figure shows, differs from all the other species of the genus in the 
yellowish-brown colour and the dark brown transverse lines, two in the forewing and one in the hindwing. 
Forewing with a minute brown discal dot. In the neuration the species differs in vein 8 being united with vein 7 
already at the base of it. Natal.
