with black; both wings with a fine, black marginal line, and the grey fringes have black spots at the end of 
the veins.“ Expanse of wings: 30 mm. Ogowe Valley near Kangwe. 
Ps. tessmanni Griinb. (63 e) is closely allied to the two species mentioned last. <$. Eorewing above tessmanni. 
black with a red spot on the posterior margin, reaching vein 3 at most and being 6% to 8 y 2 mm broad at the 
posterior margin. The spot of the hindwing is large, semicircular, leaving free the anterior part, filling up the 
posterior, greater half except a narrow border. Beneath similar as in favillacea, in the forewing the spot of 
the posterior margin is absent or it is only faintly indicated at the margin, the subapical band extends 
across the areas 3 to 6; in the hindwing the two broad, basal transverse stripes are usually fused at the anterior 
margin of the cell; the basal stripe in area 8 is broad, ferruginous; discal band broad and distinct in the areas 
1 b to 7; beside the discocelltilar spot 5 to 7 black basal spots. Subapical band of the forewing and discal 
band of the hindwing show inside and outside distinct, black borders and are besides accompanied on the outside 
by rather distinct, white submarginal spots. Forewing with a distinct black discocellular spot. — $. The spot 
on the posterior margin in the forewing broader, extending somewhat beyond vein 4, in the cell likewise traces 
of a red spot. The spot of the hindwing is oval, extending less towards the base than in the <$. Forewing beneath 
with an extensive, yellowish-red spot on the posterior margin, the other marks as in the <$. Spanish Guinea. 
Ps. russulus Ham. Druce (63 e). Wings above black; forewing with a large, distally arcuate, proximally russulus. 
almost straight red spot on the posterior margin, which is about 9 mm broad at the posterior margin and 
reaches anteriorly vein 6; hindwing with a large, red discal area covering the apical half of the cell and the 
proximal part of the areas 2 to 7; marginal band about 2 mm broad. Forewing beneath dark yellowish- 
brown, speckled with black, with some black dots in the cell and black veins; the spot on the posterior margin 
as above, but much lighter and in the areas 3 to 5 distally bordered with black. Hindwing beneath yellowish- 
brown, dusted dark, with 7 or 8 large, black dots at the base (2 in 1 c, 2 in the cell, 3 in 7 and one at the 
cell-apex) and with two undulate, black, arcuate antemarginal lines enclosing moon-shaped white submar¬ 
ginal spots and yellowish marginal spots. The species deviates from all the species similarly coloured above 
by the hinclwings being without the red spots beneath. Congo District on the Upper Cassai. 
Ps. cornucopiae Holl. was described as Durbania, but it probably belongs to the genus Pseuderesia. cornuco- 
The species has an expanse of only 24 mm and is described, as follows: Antennae, head, thorax, and ,IU " 
abdomen above black, beneath grey; the ground-colour of both wings above intensely red, on the forewing 
confined to a curved transverse band gradually growing broader posteriorly and extending from the middle 
of the costal margin to the anal angle and the middle of the proximal margin; the transverse band thereby 
almost has the shape of a cornucopia; the forewing is otherwise dark brown; hind wing with an irregular, dark 
marginal band and at the proximal margin densely speckled dark. Forewing beneath with the same red trans¬ 
verse band as above, the red colon 1 ’, however, not so bright; costal margin and apex broadly violettish-grey 
with a small, fine brown dot, the base and a subapical transverse band sooty-brown; hindwing with the same 
violettish-grey ground-colour as the apex of the forewing, and speckled with small brown spots; behind the 
middle with an irregularly curved, narrow, black transverse line and at the border with almost spear-shaped 
brown spots between the ends of the veins.“ Ogowe Valley. — If this description was really taken from a 
male, the species is probably most closely allied to Ps. russulus. 
Ps. isca Heiv. (62 f, g). <$. Forewing above jet-black, behind the middle of the posterior margin with isca. 
a minute, red spot of only about 1 mm width, reaching the fold of area 1 b. Hindwing above black with a large 
red costal-marginal spot being narrow at the base, gradually widening distally, and distally rounded off 
in a bow, reaching posteriorly vein 3 and forming also a small, triangular spot in 2; the proximal margin is conse¬ 
quently very broadly (as far as into the cell and to vein 3) black and the black marginal band gradually tapering 
towards the apex of the wing. Wings beneath blackish-grey; forewing with a large, orange-red spot on the 
posterior margin reaching vein 4 and continued almost to the costal margin by small red spots; 2 or 3 fine 
red transverse streaks in the cell and some indistinct, red spots in the apical part. Hindwing beneath dark 
grey with 4 or 5 red dots at the base and an almost coherent, curved transverse band across the middle, consist¬ 
ing of 7 red spots bordered with black of the areas 1 c to 7; marginal part with some indistinct red striae. — 
The $ only deviates by the markings above being lighter, reddish-yellow, the forewing above exhibiting a 
large spot on the posterior margin, which is broad as far as vein 4 and is then continued almost to the costal 
margin as a narrow stripe, the forewing showing at the base tivo red transverse streaks in the cell and one in 
1 b and the red spot of the hindwing above covering almost the whole cell, except some black spots. A very 
common species, occurring from Old Calabar to the Congo River. 
Ps. minium Ham. Druce (62 g) is very much like Ps. isca, but in both sexes it deviates by the minium. 
red area of the hindwing above being much larger, since it is extended to the bt\se and vein 1 b; the base with 
several black dots. Besides the forewing of the $ is above unicolorously black without markings, beneath 
without a spot of the posterior margin, and the spot on the posterior margin of the forewing beneath is in the 
$ parted by a black transverse streak of the areas 1 b and 2. Cameroon, near Bitje.
