cxtensa. P. extensa sp. n. (68 i). Similar to brunnea in the scheme of marking, though not with such a reddish 
tint, of a purer brown. Tegulae darker, colour of body and wings more like that of the following olivacea. In 
the $ the light area extends at the inner margin to vein 3 at the distal margin, farther in front only to the 
submarginal line. The oblong maculae light and edged with dark. In the $ belonging to it the interior area 
is lighter as far as vein 4, the area above it not. Hindwing brown. In the $ the apex and the angle at vein 
3 are very sharp. 32—38 mm. L. Kiwu. Type: <^2 in the British Museum. 
olivacea. P. olivacea sp. n. (68 i). Thorax with a long hair-pencil. Angle on forewing not very sharp. Head and 
tegulae blackish-brown. Thorax and forewing dark olive brown. Subbasal and interior lines dark, edged with 
light, uniformly curved. Ring-macula and reniform macula oblong. Apical line vellowish-brown, edged with 
light. Distal area with a strongly notched submarginal line, the posterior half of the area lighter. Hindwing (<$) 
pale brown, in a from Fernando Po lighter, at the inner-margin more reddish. Forewing of the much larger $ 
lighter, reddish-brown, distal margin feebly angular. $ from Spanish Guinea more greyish-brown, 2 as dark 
as the A from Cameroon, between the ring-macula and reniform macula with a yellow spot. 34—48 mm. 
Cameroon, Fernando Po, L. Kiwu. 26—29 mm. The <$ from Spanish Guinea, perhaps a separate species or 
ochrea. form: ochrea /. n. 
biarculinea. biarculinea B.-Bak. Thorax red-brown, abdomen paler. Forewing pinkish-brown, at the margin paler 
and more pink. Traces of a fine excurved and incurved basal line. A dark double line from before the apex 
to before the centre of the inner margin, filled with grey. In the centre of the distal area an indistinct gold- 
brown band. Before the margin dark lunular spots between the veins. Hindwing pale brown. $ 40 mm. 
Cameroon. 
obliquali- p. obliqualinea B.-Bak. Body brown, tegulae dark violettish-brown. Forewing claret-brown, below 
nea ' the cell lavender-brown. A fine irregular median line is traceable and a very oblique double line from the apex 
to the inner margin. The area behind it paler with traces of small nut-brown spots. Hindwing (<$) creamy white, 
at the anal margin grey. 42 mm. Lokoja District. 
ardipennis. P. arctipennis Holl. Thorax dark nut-brown. Abdomen blackish-brown. Forewing nut-brown with 
2 indistinct rings on the centre and at the end of the cell. Before the margin dark dots. Hindwing blackish- 
brown. 30 mm. Benito District. 
heterogyna. P. heferogyna Hmps. (68 i). Thorax with a long tuft. Thorax and abdomen ochreous white. Forewing 
pale red-brown, interior area and at the inner margin as far as vein 3 pale greyish-brown. Subbasal and interior 
lines brown, outside edged with white. Ring-macula and reniform macula in front open. Apical line double, 
dark, filled with light. Submarginal line undulate. Hindwing whitish, at the inner margin brownish, the $ 
more reddish brown. 32—46 mm. Natal, Rhodesia. 
spissicomis. p. spissicorilf s Mab. was perhaps only a bad specimen of heterogyna. The maculae are not mentioned 
in the description, nor is the basal line. Exterior line faded. Hindwing yellowish. Madagascar. 
In the following species the $ exhibits dense anal wool. 
albiplagiata. P. albiplagiata sp. n. (68 i). Thorax and abdomen violettish-brown. Forewing reddish-brown. The 
dark subbasal line and interior line in the submedian fold introangular. Before the centre of the w T ing pale 
pinkish-brown as far as the ring-macula which is surrounded by black and separated from the reniform macula 
by a black spot. At the base of vein 2 a light circle. Median line double, dark, from + 3 of the costal margin 
to the centre of the inner margin. A submarginal line to vein 3. From vein 4 the distal margin is narrow pinkish- 
brown. At the costal margin between both lines a silvery white spot. Hindwing reddish-brown. 34 mm. Gold 
Coast. Type: 1 $ in the British Museum. 
bella. P. bella B.-Bak. Thorax greyish-violet, tegulae ochreous brown, abdomen pinkish-grey. Forewing 
with a dark costal margin, reddish-brown, posteriorly pinkish-brown, in the cell cream-coloured. The distal 
area at the apex narrow, quickly widening to vein 2 dark red-brown, inner margin below vein 2 reddish-grey. 
In the middle of the distal area a light olive-brown dentate line. Hindwing creamy. $ less distinctly marked. 
Distal area more pink. Hindwing dark brownish-grey. Anal wool ash-grey. 34—48 mm. Lagos. 
mhnica. P. mimica Avr. 2. Thorax and abdomen dark brownish-grey, anal wool light grey. Forewing with

behind the cell whitish. From the apex a notched violettish-white submarginal line, edged with red-brown. 
Hindwing blackish-grey, from the cell to the anal margin lighter. 45 mm. South Cameroon. 
3. Genus: Pygaera 0. (Ichtyura Hbn.) 
Proboscis very short, palpi obliquely upturned, antennae rather short, in G and 2 pectinate, legs short, 
thorax with a short pencil. Forewing broad. Vein 5 very far in front. 7 + 8 + 9-1-10 stalked, mostly also 
6 stalked besides. Hindwing rounded. Vein 5 absent, 6 + 7 on a short stalk, vein 8 at % of the cell nearing
