P. spurelli R. & J. is like retusus, the thorax without a dorsal streak, forewing somewhat broader, the 
apex less produced. In the copulation-organ very different. Gold Coast. 
P. barnsi Clark. Apex of forewing not produced. Fore wing cinnamon-coloured, with a small black 
subbasal dot. Stigma small, pink. Subbasal and antemedian lines feeble, irregular, between the two post¬ 
median lines a darker area, distally to the moon-spotted submarginal line the marginal area is darker, in it a 
series of vein-dots. Hindwing of a pinkish cinnamon-colour, at the anal angle darkened as in nigriplaga. 
Expanse: 60—70 mm. Escarpment, to the west of Boga, at an altitude of 3500—4000 ft., in July. 
P. nigriplaga R. & J . (63 g). Similar to submarginalis, with more distinct, browner markings, the 
discal lines in the fore wing united into a band, subbasal dot large and distinct; stigma pale brown. Hindwing 
brownish-grey, at the anal margin, distal margin and base lighter, with 2 dark spots before the anal angle and 
a dark longitudinal streak before the anal margin on the anal fold. Cameroon, Congo. $ still unknown. — 
kivui Clark, from West Kivu (at an altitude of 5—6000 ft.), is darker brown, with more distinct markings, 
wherefore the lepidopteron appears to be more variegated. Hindwing above distinctly darker; forewing at 
the apex more pointed. Expanse about 65 mm. 
P. pauperculus Holl. (63 g). Similar to submar ginalis in the forewing, but more brownish-grey, subbasal 
spot very large; hindwing pale greyish- ochreous with a broad brownish-grey marginal band and a similar basal 
spot. Niger to Congo. In the marking and colouring senniger Jord. entirely corresponds with it, but the valve 
is here broadly trilobate at the end. Senegal to Niger. 
P. hollandi R. <fb J. (63 g) is extremely similar to pauperculus , darker brown, the spot in the forewing 
at the tornus smaller. Hindwing darker, also in the dark marginal band. West Africa. 
P. inconspicuus Strd. (64 a) is presumably nothing else but a dark and sharply marked $ of P. paupercula 
Holl. Cameroon, Congo. 
P. mutatus Wkr. (= erubescens Wkr.) (64 a). Forewing greenish-grey. Transverse lines 'blackish, 
hindwing pink, at the margin greyer, with a red postdiscal line. Natal. 
P. meander Guen. (64 a) is an easily recognisable species. Hindwing yellow with a circular black spot 
at the end of the curved postdiscal line. Marginal area grey like the forewing, in the $ narrower. Madagascar. 
P. brevis Obthr. (62 f) is smaller than the preceding species, the hindwing of a purer yellow, with smaller 
dots, without a transverse line and grey marginal area. Madagascar. 
P. delicatus Jord. (64 a). Forewing ochreous, at the inner margin basally suffused with pink, transverse 
lines blackish, before the apex a silvery grey spot. Hindwing orange-yellow, at the tornus darker. Madagascar. 
P. kindunus Strd. is an undetermined species. Margin in both wings undulate, in the forewing almost 
straight, only projecting on vein 4. Forewing bark-coloured brown, with a narrow, slightly convex antemedian 
transverse band, basally bordered by a lighter band. Distally to it a faded parallel transverse line, then a more 
distinct black transverse band not extending to the margin, but contiguous with one situate farther distally, 
thus forming a V-shaped marking which encloses the indistinct stigma. Distally to it an undulating transverse 
line, distally bordered with a lighter colour. Marginal area darker, enclosing a light band which is distinct in 
front and encloses a dark costal-marginal spot. At the tornus a semicircular black spot which encloses two 
jet-black dots. Subbasal spot black, edged with light. Hindwing lighter than forewing, with a faded dark 
marginal band (beneath more distinct), at the tornus with 3 jet-black spots surrounded by light grey. Fringes 
of hindwings at the concavities pure white, at the convexities dark. Thorax with a dorsal dark stripe. Expanse: 
62 mm. Kindu, Belgian Congo. 
P. amabilis Jord. Forewing brown, a large spot distally to the cell-end and a smaller one at the apex 
yellowish ochreous, 4 blackish transverse lines present, dark is also a cross-vein streak and the edge of the 
apical spot. Apex not produced, margin below it hardly concave, then somewhat convex. Hindwing pinkish-red, 
at the distal margin and anal margin shaded with brown, with 2 indistinct brown discal lines and brown irroration 
at the distal and anal margins. Expanse: 62 mm. Belgian Congo. — In occidens Clark the antennae, palpi and 
thorax above are deep pink instead of brown, the abdomen is pink with a thin black median line and thin black 
segmental margins. Fore wing claret-coloured, the second pair of lines being curved like an S is forked only in 
front, behind fused. Hindwing deep claret-coloured with a dark longitudinal stripe at the anal margin. Beneath 
orange cinnamon-coloured instead of ochreous. Transverse lines feebler. Tanganyika. 
P. molitor R. J. $ reddish tan-coloured, sides of body almost white; forewing pointed, margin 
below the apex concave, in the centre convex; cream-coloured with 4 brownish-olive straight transverse lines, 
only the extreme line being slightly curved. Stigma pale. Hindwing with 2 feeble parallel transverse lines from 
the anal margin, disappearing in front. The $ is smaller, with narrower forewings, the apex more produced. 
Senegal, Nigeria. The South-African race: lautus Jord. is larger, more yellowish, paler than molitor, thorax 
with a median line, the interior one of the two discal lines is broader and distally faded, inner margin edged 
with orange tan-colour; hindwing paler than forewing. Transvaal. 
P. erlangeri R. & J. Thorax and forewing loam-coloured, the forewing with a small blackish-brown 
subbasal dot, two antemedian lines, curved at the costa, the space between them filled with brown, this 
colouring being extended to the discal lines; stigma very small. The double discal line is similarly situate as in
