exterior band almost straight, the light space behind it ending taperingly. Hindwing also with black veins, 
eyespot as on forewing. Exterior line, as far as it is visible, almost straight, distal margin dark. The eyespot 
of the hindwing is absent beneath. 95 mm. Madagascar. The cocoon is double, reticulate, pale golden yellow. 
— reticolens South, (non Btlr.) seems to be a form of Leucopteryx ansorgei Rothsch. 
C. cribelli Btlr. (== mucida $ Saalm.) (57 c). $. Pale brown, almost white. The two bands on the 
forewing slightly darker. The inner one hardly bent, the outer one incurved at the costal margin. Eyespot 
pale yellow, margined with black, beneath more distinct. On the hindwing the exterior band is far from the 
margin. Eyespot the same, but beneath absent. $ 120 mm. Madagascar. Cocoon of silvery white silk, more 
dense, with holes as in Cricula trifenestrata. If the difference of the cocoon were not, one might combine at 
least the latter two species (as Saalmuller has done) and besides regard them as forms of apollina. 
18. Genus: Usta Wallgr. 
Antennae with fine double pectinations in both sexes. Shape of wings and marking similar to Heniocha. 
also the neuration. 
Type: wallengreni Fldr. 
U. wallengreni Fldr. (57 b). Body whitish ochreous, mesothorax brown. Interior line of forewing 
introangular at the median vein, exterior line with strong points at the veins, the posterior dents somewhat 
stronger. Between chocolate brown, only before the eyespot and in the submedian fold wdute, also at the base 
at the inner margin. The dents of the exterior line are outside white, then dusted with brown as far as the 
white marginal lunae. On the hindwing the exterior line is similar, before it a brown hue, behind it as on forewing. 
Eyespot in both wings grey with a white crescent towards the base, with dark orange-yellow and black rings. 
60—70 mm. South-West and South-Africa. According to Rothschild, terpsichorina Westw. is synonymous 
with it. bipliga Rbl. is probably also hardly different. Felder’s figure is rather bad. 
U. angulata Rothsch. Very similar. The notched exterior line on the forewing is not curved parallel 
to the distal margin. The dents are at the inner margin about thrice as strong as at the costal margin. Eyespots 
larger. 80 mm. East Africa. According to the figure in Nov. Zool. II, it seems to be an aberrative specimen 
at most of the common Hen. terpsichore. 
19. Genus: Pseutlapliellsi Ky. 
Palpi thin, somewhat upturned. Antennae in both sexes with fine, long, double pectinations. In the 
forewing vein 10 is also absent, 7 -f 8 stalked and 8 bent far towards the costal margin. 
Type: apollinaris Bsd. 
P. apollinaris Bsd. (= balanoal Guer.) (57 a) is a most variable species. Ground-colour mostly white, 
hyaline. On the forewing 2 orange-yellow eyespots margined with a smoky brown. The exterior smoky brown 
line is very luniform, its points fused with the marginal band in which there are large orange spots at the ends 
of the veins, apex broad smoky brown. Hindwing corresponding to it, but only 1 eyespot. — paleacea H.-Sch. 
has the same marking, but an orange-yellow ground-colour. — barotsina Rothsch. is a white form in which the 
exterior line of the hindwing is absent. 55—75 mm. Nyassa District. 
P. roseibrunnea sp. nov. (57 d). Apex of forewing more pointed in the 3 $$ before me. Pale yellow, 
costal margin of fore wing and distal margin in both wings as far as the exterior line being situate as in apollinaris 
pinkish-brown. The latter line distinct, dark. The small yellow eyespot on both wings with a fine hyaline 
spot, margined with black and pinkish-brown. In the type the second eyespot of the forewing is smaller though 
distinct. 55—65 mm. East Africa. 
P. ansorgei Rothsch. Milky white. The two eyespots of the forewing are absent, but behind the base 
of vein 5 there is a black spot. Apex above darker than in apollinaris. The yellow marginal spots are very 
small, not margined with blackish-brown. On the hindwing the exterior line is nearer to the cell than to the 
margin. East Africa. 
P. flavomarginata Gaede. Ground-colour white. The eyespots of both wings indicated by a slight 
yellow shine. Distal margin and fringes of both wings narrow yellowish, not spotted. Without a distal arcuate 
line. 55 mm. East Africa. A less extreme specimen shows the scheme of markings almost similar to apollinaris. 
The yellow eyespots are more distinct than in flavomarginata, the apex is broad pale yellow, but the distal margin 
is in both wings the same as in flavomarginata, not broad and with yellow spots. The distal arcuate line of 
both wings is slightly visible. 
P. simplex Rbl. (57 d) differs from apollinaris in the opposite direction. Milky white v ith smoky 
brown veins. Apex of forewing broad smoky brown, the distal margin below it narrower smoky brown, on the 
veins the darkening extends somewhat proximad in the not so in the The distal arcuate line and the 
yellow marginal spots are absent. — rebeli Gaede. The marginal darkening projects inwards also in the $ of 
both wings, and there are small yellow spots at the margin of the hindwing. 60 — 65 mm. Cameroon, Congo. 
A very much damaged, very large (80 mm) $ from the Congo also shows traces of the distal arcuate line. - 
Broader dark is the distal margin, almost as far as the exterior line in apollinaris, in marginilutea Bouv.
