as far as the anal tuft. Rest of abdomen lighter yellowish, though still darker than the reddish creamy 
colour beneath. Expanse of wings: 75 mm.“ East Africa: Kigonsera. 
Ph. rermei Dew. (40 b). The species is based upon the figured whether the $ which is also figured rennet. 
belongs to it, is not cpiite certain. The $ is described as follows: ,,Upper surface of the wings white with a 
somewhat yellowish tint. Forewing strewn with dark scales, with a broad grey marginal colour which is dentate 
on the hind-margin, and two dark transverse bands from the costal margin to the anal margin. On the hindwing 
above the broad grey marginal colouring is also present, though much feebler than on the forewing. The under 
surface is still somewhat lighter than the upper, with a row of blackish spots along the margin. The two narrow 
transverse bands of the forewing are not visible beneath, but the distal band is continued on the hindwing 
beneath from the costal margin to the centre of the wing. Head, body, legs, palpi whitish, partly yellowish.“ 
— The,A was described according to a badly preserved specimen. In well preserved specimens the colouring 
of the wings is said to be yellowish-grey, particularly at the base darker. The dispersed black scales in the 
forewing are more densely arranged than in the $, particularly outside of the discal black transverse stripe; 
the latter is distinct and is more vertically placed than in the $, whereas the basal transverse stripe is rather 
indistinct. The discal stripe is continued on the anterior part of the hindwing; the grey marginal band is very 
indistinct. Right outside of the discocellular there is a distinct white dot proximally edged with black. Cape 
Colony and Damara Land. 
Ph. frianguligera sp. n. $. By the shape of the wings and the colouring it resembles the races of trianguli- 
Ph. rosa ; but from all the forms of the genus hitherto known it differs in the two dark transverse lines of the (jero 
fore wing being more slanting and united at the anal margin, bordering on a triangular discal area. Body 
fawn-coloured, beneath somewhat darkened. Forewing above dark fawn-coloured or reddish-brown, at the 
base of the anal margin light yellowish, everywhere clad with black scales; the first transverse line is straight, 
the second bent; submarginal spots small and indistinct; marginal portion somewhat more densely strewn 
with black scales, whereby traces of a marginal band are produced. Discal dot absent. Hindwing above fawn- 
coloured with blackish-brown foggy sub marginal spots, but without a transverse line. Both wings beneath 
whitish with a reddish hue and light reddish fringes, a feebly bent reddish discal band and black submarginal 
dots. Expanse of wings: 57 mm. Masbuna Land: Salisbury. 
Ph. media Auriv. (40 b). A- Light fawn-coloured. Wings above with the usual black markings, media. 
Forewing with a straight first transverse line being placed vertically against the costal margin; the second 
transverse line is almost straight, at the costal margin rectangularly broken; the submarginal spots are irregular, 
indistinctly defined, united to a nebulous band. Hindwing with a complete discal band and a nebulous sub¬ 
marginal band as in the forewing. Under surface of both wings whitish-yellow with distinctly defined, separate, 
black submarginal spots. Hindwing besides with a bent discal line. 57 to 60 mm. Nyassa Land. 
Ph. grisea Auriv. Body and wings above dark grey. Wings beneath yellowish-grey. Forewing grisea. 
above: the first transverse line is slightly curved, blackish, towards the base convex and bordered with light 
grey; the second transverse line is almost straight, at the costal margin bent towards the base, blackish, towards 
the margin bordered light grey; a white discal dot; the transverse lines almost touch each other at the anal 
margin; an irregular submarginal row of blackish streaks or dots, towards the base accompanied by grey nebulous 
spots. Hindwing above with a bent dark median line. Both the wings beneath with a dark dentate discal 
line which is strongly bent on the hindwing and almost reaches the base of the hind-margin, and with traces 
of dark submarginal spots. Expanse of wings: 66 mm. Separated from all the species mentioned so far by 
the dark grey ground-colour. Kilima-Njaro. 
Ph. fuscescens Hmps. (30 f). Only the is known of this large species. Head and thorax grey, hued fuscescens. 
with brown. Antennal pinnae red-brown. Abdomen grey, liued with red-brown, and with a dark brown lateral 
line. Forewing grey, suffused with a greyish brown; the first transverse line is blackish, rather indistinct, twice 
curved; a small light discal dot; the second transverse line is blackish, curved as usual at the costal margin, 
then somewhat slanting to the centre of the anal margin, distally bordered with light and accompanied by 
a dark nebulous band; the black submarginal spots form a twice curved row. Hindwing grey, suffused with 
dark brown, in the centre with a broad nebulous, feebly curved transverse band and outside of this band with 
an almost straight transverse row of large black submarginal spots. Fringes blackish-grey. On the under surface 
the markings are less distinct. Expanse of wings: 92 mm. Congo: Katanga. 
Ph. thoracica Bull. (31b) is known to me only from the description and figure; it has a somewhat thoracica. 
different shape of the wings, but in the marking it exactly corresponds with the species of this group. Only 
the $ is known. ,,Costal margin and veins of forewing dark; the proximal transverse line of the forewing is 
transverse, slightly curved; the distal transverse line is oblique, at the costal margin bent towards the base; 
both the transverse lines are grey, broader than in Ph. rennei (40 b); the sub marginal dots are well defined, 
nearer to the margin and also on the hindwing distinct. Thorax and basal portion of the fore wing light 
ochreous. Anal wool above pale ochreous. Abdomen beneath ochreous-yellow, on the ventrum with a row 
of grey transverse streaks. Expanse of wings: 65 mm. Ruwenzori.
