21 ] 
Distal margin of hindwing concave between veins 2 and 6, so that it looks as if the distal-marginal part in tlie 
middle of the hindwing had been lost. Vein 5 somewhat more remote from 4 than usual. Only 1 species. 
Met. excavata B.-Bak. (21 h). Body and wings brownish grey. Interior line of forewing thick, dark <:.rrijaii,i. 
brown, somewhat undulate, oblique. Behind it a black dot replacing tlie ring-macula. A faded black luna at 
the cross-vein and a black dot below it, 2 black streaks above it from the costal margin. Median line fine un¬ 
dulate, black, somewhat concave at vein 2, otherwise vertical. Exterior line double, the exterior branch broafl 
as far as vein 3, vertical below the costal margin, introangular at vein 4, excurved from there to the submeflian 
fold, then vertical. Whitish behind it at vein 4 and above the inner margin. Black submarginal lunae. Hind¬ 
wing with 3 light undulate bands extending from the centre. 48—52 mm. Uganda, Togo. 
4. Genus : Clielecala Hmps. 
This genus was based upon 1 $ from Voi in British East Africa and differs from most of the preceding 
species in the absence of a distinct marginal band on the hindwing. — Pi’oboscis absent, palpi short, thick. 
Antennae of $ ciliated. Prothorax with an expanded tuft. Front tibiae with a large claw inside, hind tibiae 
with few spines. Neuration normal. Only 1 ^ known. 
Ch. trefoHata Bilr. Thorax greyish brown, abdomen brownish white. Forewing greyish white and ircjolhibi. 
reddish brown. Traces of a dark interior line. Ring-macula represented by a small black ring in the centre 
of the cell. Reniform macula large, lobularly projecting behind and below the cell and pointedly prolonged 
inward at the median vein. Exterior line marked by a faded spot at the costal margin, then from below the 
reniform macula to the inner margin. Submarginal hue indistinct, concave behind the cell and a little at 
vein 2. Hindwing brownish white, browner at the margin. $ 56 mm. East Africa. 
5. Genus : Taeliosa Wkr. 
Proboscis normal, palpi obliquely erected. Antennae of ^ tufted. Hind tibiae little spined. Forewing 
elongated. Neuration normal. Only 1 species. 
T. acronyctoides Wkr. (= Anabathra una Mschlr.) (21 h). Thorax brownish white, abdomen greyish acronycUn- 
brown. Forewing brownish white. Interior line dark, edged white inside, pointed in the cell and very far 
outward, forming two bows below it. 1 or 2 black dots at the cross-vein. A broad reniform spot below the 
cell, light or dark, edged with white and outside with black. Exterior line uniformly bent, black, finely den¬ 
tate, edged with white on both sides in front, then only outside. Black streaks from the notches inward. Sub- 
marginal line white, distinct, more dentate. Hindwing reddish brown. A d' before me is intensely dark¬ 
ened from the interior line to the margin and to the cell. 38—40 mm. Niger District, Cameroon, East Africa. 
6. Genus: rioplioticlia Hmps. 
Proboscis normal, palpi obliquely porrect, frons with a horny plate. Antennae of S tufted. Anterior 
tibiae slightly spined, hind tibiae altogether with spines. Neuration in both wings normal. Only 1 species. 
L. trisema Hmps. is somewhat similar to Crypsotidia conijera (21 h) in its size, habitus, the light loam- irlscma. 
coloured yellow forewings and the white hindwings. Thorax light brown, abdomen whitish ochreous. Fore¬ 
wing brownish white, browner at the costal margin as far as the cell-end. Interior area except at the base and 
the marginal area except at the apex dusted with blackish. Interior line white, projecting below the costal 
margin and above the inner margin, incurved between them. A little black lima at the cross-vein with a streak 
from the costal margin above it. An 8-shaped white, black-edged spot before it from the centre of the cell to the 
submedian fold; from there a dark line to the inner margin. Exterior line double, dark, filled with white, uni¬ 
formly bent, finely dentate. A small black spot outside of it at the costal margin, below it as far as vein 7 
brownish ochreous as far as the margin. Submarginal line fine, white, undulate. Hindwing white, narrowly 
brown at the margin. U 28 mm. East Africa. 
7. Genus : Hypotacha Hvips. 
Proboscis normal, palpi obliquely erected, frons with a projecting hair-pencil. Antennae of U tufted. 
Front tibiae without spines, hind tibiae with spines at the end. Forewing elongated. Neuration of both wings 
normal. Type: retracta Hmp)S. The 4 species known occur in Africa and Arabia. 
H. nigristria Hmjjs. (21 g). Body and forewing violettish brown. Interior line black, oblique as far as nlgriairki. 
the submedian fold, undulate, then inward. A blackish spot at the middle of the costal margin and an intense 
streak in the cell-end. Exterior line black, excurved from % costal margin to vein 3, then inward to the streak 
at the cell and further obliquely outward to the inner margin. Submarginal line pale, edged dark inside, extra- 
angular at vein 7, otherwise undulate, uniformly bent. Hindwing whitish, somewhat reddish at the inner 
margm, violettish brown at the distal margin. $ 38 mm. Cape Colony.
