PHI ALA. By M. Gaede. 299 
It may be that pulverea Dist. was a $ of this species without any bands. In this case this name would be prior. 
G 38 mm. South-West Africa. 
P. albidorsata sp. n. (47 e). Head orange-yellow, thorax white, abdomen orange-brown. Wings albidorsata. 
white with few black scales. The fine black apical line on the forewing is similar as in niveociliata Strd. The 
dots on the hindwing are arranged as in flavina. Beneath only at the margins and particularly at the apex 
of the forewing ochreous brown. S 38 mm. Betchuana Land. Type in the Berlin Museum. 
P. bistrigata Aur. (41 h). Wings white, strewn with black scales. Forewing with a broad band from bistrigaia. 
near the apex to the centre of the inner margin, slightly excurved below the centre of the wing. Before the 
distal margin a somewhat feebler narrower band. On the hindwing a uniformly curved median band and a 
very narrow one almost at the margin. 40 to 50 mm. Cape Colony. — eurvistriga Strd. is much more eurvistriga. 
intensely dusted with dark in the cell and shows a mostly distinctly undulating marginal band. $ 50 to 60 mm. 
East Africa. 
P. unistriga sp. n. (41 g). Head and thorax light brown, abdomen orange-brown. Wings white. Apical unistriga. 
line similar as in bistrigata, but the distal line is absent. The patch in the cell is much feebler. Hindwing at 
the base somewhat ochreous. No traces of a band. Beneath slightly brownish. G 40 mm. Nyassa District. 
Type in the Tring Museum. * 
The three following species are somewhat allied to venusta. 
P. simplex Auriv. (47 e). Head and tegula yellowish. Thorax white. Wings pure white. The band simplex. 
on the forewing is fine, beginning vertical at the inner margin as in venusta. On the hindwing it is slightly waved, 
its end near the anal angle. Beneath white with slightly yellow veins. 46 mm. East Africa. 
P. pretoriana Wichgr. (44 f). Compared by the author in the shape of the marking with marshalli, pretoriana. 
by Strand, who sarv the type, with venusta. According to a specimen of the Berlin Museum, probably an 
aberrative simplex, in which the row of dots on the hindwing bends distally from vein 6. 50 mm. Transvaal. 
P. cutokularis Strd. (44 e) may be the form of simplex corresponding to venusta-angulata. The cubicularis. 
indistinct band of the hindwing extends distinctly less curved. On the forewing there are besides traces of a 
marginal band to be noticed. 50 mm. East Africa. 
b) flavipennis- group. 
Not white species. Wings more or less densely dusted in the median area or across the whole surface. 
Fore wing without a median band. 
P. flavipennis Wllgr. (41 i). Thorax and forewing yellowish-white. Fringe orange yellow. A band flavipennis. 
of black scales from the apex in the direction to the centre of the inner margin as far as the median vein and 
along the latter farther inwards. Before the distal margin a band-like accumulation of scales. Hindwing orange- 
yellow, at the distal margin dusted with blackish. 38 to 40 mm. Transvaal. 
P. polita Dist. (41 h). Also the thorax and forewing orange yellow. On the median vein and between polita. 
the veins 2 to 6 dusted with black of a variable intensity. Hindwing with but single black scales. 40 mm. 
Transvaal. 
P. dasypoda Wllgr. (41 i). Wings slightly brownish. Near the distal margin of both wings a row of short dasypoda. 
blackish-brown streaks, centrally excurved. Behind it on the forewing sometimes a brownish undulate line. 
On the hindwing dark scales before the margin. S 45 mm. Transvaal, Natal. 
P. fuscodorsata Aur. (41 g) is similar to a small somewhat greyish-yellow dasypoda. In the forewing fuscodorsa- 
the row of streaks is fused into a band. The median vein and partly veins 2 to 4 with an accumulation of dark ta - 
scales, also towards the inner margin dusted with dark. 34 mm. East Africa. 
P. abyssinica Aur. Thorax and forewing greyish-brown, forewing densely dusted with dark brown, abyssinica. 
so that only the veins remain light. From near the apex to the centre of the inner margin a broad dark brown 
band, behind it somewhat lighter. Hindwing similar, on the veins blackish-brown streaks. $ less intensely 
dusted. 50 mm. Abyssinia. 
P. tanganyikae Strd. Similar to abyssinica. Band of forewing straighter. Hindwing without the tanganyi- 
black streaks. 50 mm. Tanganyika District. kae - 
P. patagiata Aur. Very similar to vaninia. Patagia with black hairs. Ground-colour of forewing darker, patagiata. 
but also with white veins. Hindwing grey with a black postmedian band and a marginal band. $ 44 mm. Cape 
Colony. 
P. vaninia Stoll. (44 f). The whole body orange-brown. Patagia whitish with a few brown hairs, vaninia. 
Forewing dark ochreous brown, veins broad white. Hindwing the same, but paler in the S', in the only $ whitish, 
only at the margin somewhat brownish. 44 mm. Cape Colony.
