and broader forewing the transverse line of which almost terminates into the apex of the wing and in the uni¬ 
coloured hindwing. — The pupa rests in a tenacious and dense though thin web. Cameroon and Congo District.

the forewing is still more slanting than in the abovementioned species, beginning near the apex of the costal 
margin and ending at the base of the anal margin. Cameroon and Northern Congo District.

dark red-brown ground-colour of the forewing and the marginal band of the hindwing, as well as in the basal 
portion of the hindwing being dingy white, and the middle segments of the abdomen being above white.

captured in copula, nobody would believe them to be homogeneous. In the <$, which otherwise corresponds 
with the two $<$ described above, the hindwing is uniformly rounded off. The $ recalls that of P. mesoleuca 
(32 f), but it has a blackish-grey ground-colour of the forewing with a black discal dot and entirely lacks the 
dark oblique band. Mashona Land. 
P. lineata Auriv. (— choerocampoides Holl.) (33 d). The $ is easily recognisable by the figure. The lineata.

scantily clothed with yellowish bristles. Cameroon and Gabun. 
P. tligrescens Auriv. (33 d). <$. Blackish-brown or smoky black. Upperside of head and of thorax dark nigrescens. 
red-brown. Antennae yellowish-brown; apex of palpi narrow yellowish. Forewing above dark red-brown with 
four feebly bent or almost straight blackish transverse lines extending from the costal margin near the apex 
of the wing to the centre of the anal margin; the middle ones of these transverse lines almost form one line 
sharply separated from the two others by the ground-colour exhibiting here a slight violet reflection. Fore wing 
beneath blackish, at the anal margin lighter. Hindwing on both sides almost black. Congo District.

lineata (33 d), but it is particularly distinguished by the two double transverse lines of the forewing being almost 
entirely broken up into black dots, situate on the veins; the lines themselves are sharply broken in a zigzag 
shape, forming an angle on each vein and in the centre of each area, though often so finely and indistinctly 
that they are hardly to be seen; particularly the proximal transverse line is only noticeable by the dots being 
arranged in two rows. Thorax reddish-grey a little mixed with violet. Abdomen above yellowish. Forewing 
with the same ground-colour as the thorax; the proximal double line is very indistinct, apparently only composed 
of two irregular rows of dots, beginning a little behind the centre of the costal margin and terminating at the centre 
of the anal margin; the distal double line is almost parallel with the proximal line and proceeds from the costal 
margin near the apex of the wing; the submarginal line is dark, irregularly broken, the space between it and 
the distal margin is darker than the ground-colour; the base of the wing shows a few small and fine longitudinal 
streaks parallel with the veins. Hindwing at the distal margin rounded off, above monotonously reddish-yellow, 
with a darker marginal band. Wings beneath darker fawn-coloured; the distal transverse band of the forewing 
is blackish and straight, and the submarginal line dark brown, only interrupted by the lighter veins; hindwing 
at the costal margin narrowly darkened. — The $ is much larger (length of a fore wing 42 mm), fawn-coloured; 
the proximal transverse band is slightly bent, towards the base bordered with light, the distal one is straight, 
distally broadly bordered with light, and extends from the costal margin near the apex of the wing to the 
hind-margin at the end of vein 1; marginal portion darkened, but the submarginal line indistinct. Senegal.

Second Group of Species. 
This group comprises the species being most closely allied with P. capensis L. The characteristica have already been 
mentioned above (p. 242). 
P. capensis L. (= pithyocampa Cr., ? aluco F.) (33 c). Head and thorax above light grey or brownish- capensis. 
grey; collar and dorsum sometimes with a brown longitudinal line. Abdomen above fawn-coloured, brownish- 
grey or yellowish. The whole under surface is darker, red-brown. Fore wing above very variable; its ground¬ 
colour is fawn-coloured grey, at the base and distal margin usually lighter; transverse lines double, filled with 
whitish, in the £ notched, in the $ undulate, slantingly extending from the costal margin to the anal margin 
and bordering on a broad median band being widened at the costal margin and generally darkened in the $; 
submarginal line irregular, formed of brown spots, in the areas 3 and 4 curved towards the margin, narrow 
or almost interrupted. Hindwing above fawn-coloured or brown; almost invariably with a pale greyish marginal 
band. Wings beneath brown, at the distal margin more or less lighter. — The beautiful larva is beneath black
