a row of small black dots from the apex of the wing to the hind-margin near the anal angle; a small 
white, black-curled dot at the end of the discal cell. Hindwing reddish fawn-coloured, the darkest at the base 
and hind-margin; a fine indistinct black line traverses the hindwing from the costal margin, near the apex, 
almost to the centre of the hind-margin without reaching it completely. The under surface of both wings is 
reddish fawn-coloured with the transverse lines and dots as above, but red-brown, and with submarginal dots 
also on the hindwing. Head, thorax, abdomen, and antennae reddish fawn-coloured. — Forewing and hindwing 
uniformly light whitish fawn-coloured, with a reddish hue, densely speckled with black scales; forewing from 
the costal margin to the hind-margin traversed by two bent black lines, the first near the base, the second 
behind the middle; a submarginal row of spots as in the The transverse line of the hindwing is very indistinct. 
The under surface is much paler than the upper surface and exhibits on both wings a submarginal row of large 
black spots. Head, thorax, and abdomen of the same colour as the wings. The anal pencil is very large and 
somewhat darker than the abdomen. Antennae and legs reddish fawn-coloured. Delagoa Bay“ This description 
proves that in the $ of the typical Ph. rosa the first transverse band of the forewing on both sides and the 
submarginal dots of the hindwing above are absent and that above in the $ both the transverse lines of the 
fore wing are present, whereas the submarginal dots of the hindwing are absent. An almost cpiite similar d 
is before me from Kigonsera in East Africa; it only differs in the postdiscal line of the forewing not being distally 
bordered with light. — In montibia Strd. (31 a, b) £ the first transverse line of the forewing above is distinct, 
almost straight, and the second on both wings distally accompanied by a brownish nebulous band. There is 
still uncertainty about the question whether and how the $ differs from the $$ of the other forms. Kilima- 
Njaro. — natalica var nov. I denominate the form of which several specimens are before me from Natal. It 
is evidently closely allied to the typical form, but above it has a distinct subbasal transverse line of the 
forewing and submarginal dots of the hindwing at least in 4 to 6. From montibia it only differs in the ground¬ 
colour above being uniform as far as the margin and not darkened outside of the distal transverse line. The 
latter is towards the distal margin very finely bordered with whitish and is continued on the hindwing in an 
entirely straight line at least to the centre. The discal spot of the forewing is small, white, blqnk-curled. On 
the under surface the discal line is brown, almost parallel with the margin, and is continued at least to vein 
2 of the hindwing. Both wings with submarginal dots. The $ which I received together with the dc? 
has an expanse of wings of 90 mm, but in the marking it corresponds exactly with the $<$ an d only differs 
in the much lighter greyish-white ground-colour and the upper surface being speckled with dark scales. -— 
squamata Strd. ( ? = flavescens Wichgr.) (31 b). Forewing above light fawn-coloured, at the base somewhat 
lighter, with black transverse lines the distal one of which is rectangularly broken at the costal margin and 
posteriorly for a short distance continued on the hindwing. A minute black discal dot of the fore wing. Both 
wings without submarginal dots. Under surface of both wings dingy light greyish with a faint ochreous hue 
and without any other markings but a dark median transverse line; at the costal margin of the hindwing there 
are traces of one or two dark spots. East Africa near Langenburg. Tanganyika. — ochrascescens Strd. 
(31 1)). Both wings above light greyish-yellow; forewing with a black discal dot and a black postdiscal line, 
but without submarginal dots. Hindwing and the under surface of both wings without markings. Body ochreous; 
tarsi dark. East Africa. Probably the $ of squamata. — The larva of var. natalica is before me owing to 
the kindness of Air. E. L. Clark from Natal. It is cylindrical with a blackish or blackish-brown ground-colour 
which, however, is only distinctly prominent beneath and on the segmental margins, and everywhere clothed 
with long brown hair. The dorsal side is bluish-grey and by the black segmental margins divided into large 
quadrangular areas; on the sides the segmental margins and the surroundings of the black spiracles of the joints 
4 to 10 are densely clothed with short white silky hair; sides of the head red-brown, frons light yellow with 
two black spots; clypeus black. 
Ph. clara B.-Bak. is described as follows: Head, thorax, and abdomen pale creamy. Both 
wings pale creamy, feebly lined with reddish. Forewing with a fine dark, slanting, prediscal transverse line and 
a similar postdiscal line which is bent towards the base at the costal margin; these two lines approach each 
other at the anal margin. Traces of a small dark dot at the end of the discal cell. Hindwing without markings. 
Expanse of wings: 79 mm. Rhodesia.“ — To this species may also belong a d from the Nyassa Land, which, 
however, differs in the distal transverse line being at least continued to the centre of the hindwing, and the 
expanse of wings being only 66 mm. 
Ph. rufescens Wichgr. is unknown to me, but probably to be ranged here. The description says: 
,,Upper surface: fore wing: ground-colour a silvery lustrous creamy yellow turning reddish yellowish-brown 
towards the base by being more and more densely haired. Costal margin yolk-coloured. Fringes reddish yellow. 
The spot at the cell-end is white, somewhat oval edged with black. Discal band strigiform red-brown, extending 
from the second third of the costal margin obliquely almost to the centre of the anal margin, rather straight 
with a slight proximal bend from veins 7 to 9. Hindwing: ground-colour as above, but the intense fur-like 
hairing of the base is not so dark as in the forewing. The slightly bent discal streak extends from the centre 
of the costal margin to the centre of the anal margin, gradually disappearing hindward. Fringes reddish-yellow. 
Under surface: forewing and hindwing uniformly creamy without the least trace of a spot or band. Antennae 
yolk-coloured like the head, palpi, feet, dorsum and the beginning of the abdomen, as well as a comb of bristles
