with two broad orange-yellow longitudinal lines, above white with a broad, orange-edged longitudinal band 
widening somewhat in the centre of each joint; the sides are clothed with long brownish-yellow hair; the magnifi¬ 
cent spots are relatively small, surrounded by brownish-yellow hair; dorsal band with black bristles and with 
a tuft of black bristles on the 11th joint; head with a light median line. Cape Colony and Natal. 
P. bifascia Walk, is unknown to me, but probably allied with P. capensis or only a form of it. The 
insufficient description runs as follows: Fawn-coloured, head and thorax grey; the former in front fawn- 
coloured. Forewing near the anal margin with a brown basal streak and with two very slanting, scarcely undu¬ 
lating whitish transverse bands; the first band near the costal margin almost rectangular; the second band at 
the costal margin on both sides widened and towards the base accompanied by a brown band; distal margin 
and the whole hindwing fawn-coloured.“ Expanse of wings: 55 mm. South Africa. 
P. obscura Walk. (= ferruginea Feld.) (33 d) differs from P. capensis in the dark brown or blackish- 
brown ground-colour of the thorax and forewing. The marginal portion is generally more greyish than in the 
figure, and the hindwing often shows a greyish marginal band as in capensis. $ unknown to me. — The larva 
differs from that of capensis in the upper surface and the sides showing a pure light grey ground-colour and 
light red lateral hair; the dorsal band is white, broadly bordered with orange-yellow. Natal. 
P. phoeea Drc. is likewise closely allied with capensis , if I have not mistaken the description. 
Forewing red-brown, at the apex and distal margin the darkest; a broad, dark brown band, which is centrally 
narrower, traverses the wing from the costal margin behind the middle almost to the middle of the anal margin; 
on each side of this band the wing is densely speckled with white scales; fringes red-brown. Hindwing monoton¬ 
ously yellowish fawn-coloured. Both wings beneath reddish fawn-coloured, speckled with a few grey scales. 
Head and thorax above coloured like the forewing; abdomen yellowish, at the apex red-brown. The whole 
under surface dark red-brown; tarsi curled white. Expanse of wings: 108 mm.“ It may be the $ of P. obscura ? 
Delagoa Bay. 
P. sericeofasciata Auriv. (33 e). d 1 unknown. The differences between the $ and that of P. capensis 
are shown in the figures. Sometimes the median band of the fore wing is very narrow or even interrupted in 
the areas 2 to 4. Natal and Congo District: Boko District. 
P. albofasciata Auriv. (33 f) is also a form closely allied with the preceding species. The $ is easily 
recognisable from the figure; the d is much smaller (length of forewing 23 mm) and darker coloured. Head, 
thorax, and forewing above dark chestnut-brown; thorax with a few fine grey lines in the centre and the patagia 
laterally grey-haired; the white transverse lines of the fore wing are very distinct. Cape Colony. 
The three following species are distinguished from the others by the fringes of both "wings, or at least of the 
forewing, being spotted light yellowish at the ends of the veins. In the $ the distal transverse line extends close at the 
distal margin and is distally convex. The $5 at least of the two first species have white hindwings with a very broad dark 
marginal band. 
P. morosa Walk. (= Richelmanni Weym., sopliax Drc.) (33 f). Both sexes are figured, for which 
reason it is unnecessary to describe the rather confused marking of the forewing. The colour of the dorsum 
and forewing varies in the d between fawn-colour and blackish-brown. Delagoa Bay to Kilima-Njaro. 
P. nilotica Auriv. d- Size and shape of wings exactly as in morosa -d, but body and forewing almost 
black; abdomen on the basal sides dark brown; fore wing at the distal margin somewhat lighter dark grey; 
its marking is hardly visible or only at the distal margin which is undulating with small yellowish spots at 
the ends of the veins. Hindwing above blackish-grey, at the hincl-margin and base brownish, and with an 
indistinct brownish postmedian transverse band; distal margin undulating; fringes blackish with a lighter 
basal line. Sudan. 
P, fulgurata Auriv. (35 c). d- Body dark red-brown, above on the head and thorax mixed with grey. 
Forewing above as far as the proximal transverse line light yellowish, behind it fawn-coloured or brown; both 
the transverse lines are double, dark brown or blackish and very deeply notched; the proximal line at the costal 
margin bent round far towards the base; but the distal line is parallel with the distal margin and terminates 
quite near the apex of the wing. Hindwing above dark brown, at the distal margin gradually changing into 
blackish. Both wings beneath dark brown, at the distal margin blackish with yellowish veins. — In the $ 
the whole under surface, the head, collar, and patagia are dark red-brown, the dorsum otherwise lighter brown 
and the abdomen above greyish with brown hair. Forewing above brown and marked as in the d> but with 
much thicker and more obtusely dentate transverse lines. Hindwing whitish, at the costal margin as far as vein 
6 and at the distal margin broadly violettish-brown; the marginal band is tapering posteriorly and ends in 
a point at vein 1 b. Expanse of wings about 85 mm. Ashanti to Kassai in the southern Kongo District. 
P. jamiesoni B.-Bak. is known to me only from the description. As Bethune-Baker compares his 
species with fulgurata , I place it here. ,,d- Head and thorax dark rusty brown; antennae lighter; abdomen 
also lighter rusty brown. Forewing dark rusty brown, the veins at the base and in the middle lighter; a very 
broad yellowish-brown postmedian band extends in a uniform bow almost from the apex to the centre of the
