and is redder than the + 35—50 mm. Cameroon, East Africa. 
Pr. splendida Warr. Forewing light ochreous, the reticulated lines and veins light rusty red, costal splendida. 
margin darker. The interior line is slightly curved from % of the costal margin to the centre of the inner margin. 
The median line from the centre of the costal margin excurved to the interior angle. The exterior line from 
% of the costal margin, almost touching the preceding line behind the cell, to the distal margin above the 
angle where it bifurcates. Subapical line forked at the costal margin. Hindwing similar. $ 34 mm. Natal. 
Pr. ansorgei Warr. Dark ochreous with blackish-brown reticulated lines. Costal margin dark with ansorgei. 
darker spots. Interior line from % of the costal margin to the centre of the inner margin, behind it two 
parallel lines enclosing a brown area and united at the lower angle of the cross-vein. Exterior line from % of 
costal margin, curved above vein 6, to the inner angle. Hindwing in the marginal area reddish, with a blackish- 
brown spot at the cross-vein. $ 54 mm. East Africa. 
Pr. viftiferalis Gaede (= medjensis Holl) (75 i). Ground-colour ochreous with fine and coarser red-brown vittiferalis. 
reticulate lines which are partly confluent and thereby form an interior and an exterior band on the forewing. 
On the hindwing a feeble interior and broader median band. In the forewing veins 7+8 only shortly stalked, 
d 35 mm. East and West Africa. 
Pr. tessellata Warr. Ochreous, densely covered with dark reticulate lines, and with triangular brown lessellata. 
spots at the costal margin of the forewing. Of the brown main lines two near the base are vertical, behind them 
two at the costal margin are slightly excurved, the following two above the cell-end unite at the black spot at 
the cross-vein and again in the submedian fold, being separated between these places. Behind them a notched 
line to the inner angle, and the subapical line. On the hindwing 3 exterior lines and a spot at the cross-vein. 
d 1 40 mm. Nyassa District. 
Pr. orbiferalis Gaede (75 i). Red-brown, with a violet gloss. Both wings with small yellow spots and orbiferalis. 
larger white somewhat diaphanous ones. Marginal line red-brown. 24—28 mm. Togo. 
10. Genus: Tridesmodes Warr. 
Forewing at the costal margin typically somewhat concave, apex pointed. Veins 7 + 8 + 9 stalked, 
10 free, approximating 9. Hindwing somewhat triangular. Veins 6 and 7 separated, 8 close next to the cell. 
Type: ramiculata Warr. The species are wdiite and all very much alike. They may not all be distinct species. 
Tr. ramiculata Warr. Wings somewhat diaphanous, with numerous brown reticulated lines and very ramiculata 
fine striae. On the forewing two median lines more distinct with a brownish spot between them at the costal 
and inner margins. The last line bent towards the distal margin. Hind wing similar, with brown veins. <+19 mm. 
East Africa. 
Tr. elephantinalis Karsch (76 h). Costal margin of forewing violettish-brown with short striae. The two elephanti- 
median lines only form a spot at the inner margin. The faint lines generally run parallel and vertically to the 
inner margin. Hindwing only with few (about 3) lines. 26—30 mm. Cameroon. 
Tr. ansorgei Warr. (76 i). Costal margin of forewing blackish brown. Lines more or less reticulated, ansorgei. 
two interior lines being undulated, two exterior ones strongly curved, and a cruved submarginal line ending 
at the inner angle and despatching 2 branches to the distal margin. Below the apex 1 or 2 black dots in distinction 
of all the other species. Marginal line black. Hindwing with less prominent single lines. 22—24 mm. Uganda. 
Tr. cymaeasticha B.-Bak. Costal margin of forewing reddish-brown. Lines lilac grey; from them cymaea- 
about parallel lines cross the wing. Hindwing similar. £ 30 mm. Niger District. 
Tr. phricosficha B.-Bak. Lines greyish ochre, undulated. Traces of a cellular spot. Exterior line more phrico- 
prominent, as well as the double submarginal line with pink scales. Behind it black streaks which begin at the 
costal margin with 2 black apical dots. This mark also occurs in Rhod. nudicornis , but it by no means infers 
their identity. $ 32 mm. Niger District.

slicha 
11. Genus: Iflatlioris Gn. 
The two species, especially the first, resemble Striglina, but differ in the long-stalked veins 9 + 10 of 
forewing. Type: vocata Wkr. from South America. 
M. lenistrialis Hmps. (= monotonicata Strd.) (75 i). Fiery red-brown, with numerous though rather lenistrialis. 
indistinct dark striae. On the lighter underside a dark median band on the forewing, very feebly continued 
on the hindwing. Tarsi with distinct white rings. 22—25 mm. Gold Coast, Togo, Niger District. Spanish 
Guinea. The <$ {— nigranalis Wrr.) has a black anal tuft. 
M. magica Gaede (75 i). Blackish-brown with indistinct lighter brown bands on the forewing except in magica.
