liquely outward as far as vein 6, then undulated, straight, somewhat inward. Submarginal line slightly angled 
at vein 7, straight, faded. Hindwing pale brown as far as the middle, then narrowly orange, broadly black 
behind it, narrowly orange at the margin. 52—60 mm. West Africa. — zanzibarica Hrnps. (26 b). described zanzUmrlra. 
from East Africa, occurs also in the Cape Colony and Xyassa Land. The colour of the forewing varies a little 
as also in catocalina, the scheme of markings is quite the same. Very different, however, is the aljdomen and 
hindwing which are orange, while of the large black spot of catocalina only the middle part of a narrow short 
band is left. The band is not so strong as Hampsox figures it in any of my (JrJ or 2$. 50—55 mm. 
H. euryplaga Hynps. (26 c). Thorax orange, abdomen pale brown. Forewing light red-brown, the lines miri/jihir/a. 
dark brown. Interior line oblique, double, undulate, faded. Reniform macula grey, faded, with black marginal 
dots. Median line double, faded, undulate, inward close behind the reniform macula, above and below it. 
Exterior line distinct, notched, shaped as in catocalina. Submarginal line notched, faded, light, brown before 
it as far as the exterior line, whitish at the margin. Hindwing orange with a large round black subapical spot,

H. klugii Bsd. (26 b). Thorax and forewing reddish orange, abdomen orange. The lines on the forewing ktut/;}. 
faded, dark brown. Interior line double, undulate, the interior branch more or less faded. Reniform macula 
small, edged with dark. Median line also double, notched, undulate, encircling the reniform macula at a greater 
distance from it than in euryplaga, vertical from the lower cell-angle, the exterior branch often extinct. Ex¬ 
terior line shaped as in catocalina. Submarginal line of extinct spots, with a silvery violet hue over it, before 
it traces of another row of spots. Hindwing orange with a black spot between veins 6 and 2, narrowly prolonged 
to the anal angle. — In rivularis Btlr. the thorax and forewing are more yellow, the spot on the hindwing rivulari<i. 
slightly undulately edged. — maculilinea Strd. (26 c) is a less superfluous name. The shape of the lines is not macuUUnea. 
different, only the mediair line seems to be always single, but they consist of mostly much darker sjrots, and 
the reniform macula is blackish, too. A row of black spots extends from the apex to the submarginal line, the 
white shine at the submarginal line is absent. — croceipennis IT/rr. differs little from niaculilinea. The median crocelpenms. 
line is feeble, single, slightly S-shaped. Black marginal dots on the hindwiirg between veins 5 and 2. — varians variam. 
2Iab. is a subordinate form of it, in which the interior line is accompanied inside by black spots, as in maculi¬ 
linea; croceipennis is without them. The apical row of spots is absent in varians as well as in croceipennis. 50 
to 60 mm. Vest to East Africa, Madagascar. 
H. xanthoptera Hmpjs. (26 c) is probably also oirly an extreme form of klugii. Body and wiirgs pale xanthoptera. 
orange, the lines pale brown. Interior line single, a blackish spot before it in the submedian fold. Reniform 
macula present, median line single. Exterior line feebly double. Of the apical spots of the form maculilinea 
only that below vein 6 is present, very large and black, a smaller one below it The margin is narrowly red- 
brown, except at the apex. Hindwing quite orange, somewhat brownish only near the anal angle. — demacu- demaculaia. 
lata Strd. has lost also the spot before the interior line and the spot below vein 6, and is thus the very con¬ 
trary to maculilinea. 6(i—65 mm. Vest Africa, Delagoa Bay. 
33. Genus: Tolua ITAr. 
16 species, all of them Ethiopian, form this genus; throughout very large, robustly built lepidoptera 
with a rather bright marking to the varied designs of which the names vzrsicolor, meandrica, variegata etc. 
refer. — Metathorax with a tuft, also the basal segments of the abdomen tufted. Tibiae of rj long-haired. 
Posterior tibiae with spines. Forewing with a round a|)ex. Xeuration normal. Type: versicolor ITA’?'. 
T. versicolor ITA’r. (— versicolora limps.) (26 c). Thorax and forewing blackish bro’Am. Interior line versicolor. 
ligther brown, projecting outward below the costal margin, then somewhat inward, slightly introangidar in 
the submedian fold, dusted bluish white. Exterior line from ® b costal margin to vein 4 as a thick white beam, 
then finely bluish white undulated as far as the submedian fold, from there straight to the inner margin. 
Before the exterior line another indistinct bluish white parallel iindulate line, a black spot close behind it 
above and below vein 3. The apical line is distinctly white at vein 6. bent down before the distal margin and 
more feebly to the costal margin, the apical area dark rusty brown. Abdomen and hindwing dark rusty brown. 
60—70 mm. Vest Africa. 
T. sypnoides Btlr. (= daedalea Mab., meandrica Saalm.) (26 d). ^ body from reddish brown to greyish sypuoidc.s. 
brown. Forewing olive brown at the base and apex, median area white, dusted brownish green. Interior line 
black, notched, vertical. Two fine black dots at the cross-vein. From a black spot above it at the costal 
margin the fine dark median line proceeds, outward as far as vein 4, then inward. Exterior line intensely 
black, dentate, outward as far as vein 3, then more feebly inward. tSubmarginal hne indicating the exterior 
border of the apical spot, forming long waves, disappearing below it in the light margin. Hindwing reddish 
brown like the abdomen or whitish as far as behind the middle of the wing, where there is a fine dark median 
line, the rest brown. The smaller $ shows the median area of the forewing dusted brownish black or greenish 
black. A black square at the cross-vein, filled with olive brown, in white surroundings. The median line more 
distinct than in the S- The white submarginal line more distinct in the lower part owing to the dark surround¬ 
ings. The under surface is also very elegantly coloured. 52—65 mm. Vest and Soidh Africa. (Madagascar.
