and 4. Light yellowish-brown spots behind it, smaller in front, from which black lines extend to the margin. 
The veins are edged with white on both sides. 38—40 mm. Transvaal. ■ 
M. actinophora Hmps. (8 k) resembles an ochreous brown typica, but the exterior line is finely double, 
black, the space behind it lighter. Larger dark spots at the margin. Hindwing of white, of $ brownish. 
25—35 mm. East Africa. 
M. heterochroa Poult. (8 1). Antennae of ^ more strongly pectinated, ciliated in the Forewing light 
bluish-grey, somewhat brownish at the costal and distal margins, the veins with dark stripes. Interior line 
fine, strongly dentate, coniform macula distinct. The reniform macula is a yellow spot. Exterior line fine, 
edged with yellow outside, brown inside above the inner margin. Blackish at the margin above and below 
the middle. $ tinged with red-brown. Ring-macula white, reniform macrda and the margin behind the ex¬ 
terior line intensely red. Hindwing reddish-broAvn. 30—35 mm. Somaliland. 
2. Antennae of finely serrate, of $ ciliated. 
M. hemileuca Hmps. (8 1). Thorax and the space below the cell of the forewing dark broAvn. A faded 
dark stripe in the base of the sub median fold. An interior dark line is traceable above the inner margin. Reni¬ 
form macida AA’hitish ochreous, rather indistinct in the light ochreous costal margin, only inside and beloAA^ it 
is someAA-hat edged blackish. The exterior line is recognizable from vein 6, and the submarginal line from 
vein 7, introangular in the submedian fold. HindAving Avhite, brownish at the apex. $ 32 mm. Sierra Leone. 
28. Genus: JDelta Saalm. 
Proboscis and palpi normal. Antennae of d ciliated. The tegulae form an edge in the middle, continued 
on the thorax. Very small tufts at the base of the abdomen. Neuration normal. Type: stolifera Saalm. 
D. intermedia Brem. This species occurs also in Siberia and has therefore been dealt AAoth in Vol. Ill, 
p. 202, and figured on pi. 42 c. Separated from the folloAving species by its lighter greyish-broAAm ground-colour 
and roAinder reniform macida. Ring-macula al)sent. 28—30 mm. Transvaal, Natal, Eastern Asia. 
D. stolifera Saalm. {= campyla Hmps.) (8 1). ForcAA'ing Adolettish-broAvn at the costal margin and often 
as far as beloAA' the cell, yelloAAdsh-broAAUi toAA'ards the inner margin, Avith a distinct dark line below the cell and 
aboA-e the inner margin. Ring-macula small, often very narroAv; reniform macula moon-shaped, terminating 
into a broad rusty red difLise spot. Black marginal arroAvs form the usual W beloAV the cell, Avith light dots 
in them near the margin. Saalmuller's figure is not A-ery good, but the W is expressly mentioned in the 
descrijAion. HindAA'ing hyaline AA'hite, broAvnish at the margin. 35-—38 mm. Sierra Leone, Togo, Nyassa Dis¬ 
trict, Madagascar. 
D. phoenicraspis Hmps. (81) is presumably only a form of stolifera. Costal margin of foreAA-ing redder, 
the ground-colour a purer yelloAv. Not rusty red behind the reniform macula. The tAvo dark radial lines are 
absent. $ 38 mm. Rhodesia. 
29. Genus : f^tomafroutia Hmps. 
Proboscis absent, palpi short, thin. Erons AA'ith a large pointed bump. Antennae of $ serrate. Thorax 
and abdomen AA’ithoAit a tuft. ForeAving: veins 7 + 10 +8+9 stalked, vein 3 far before the angle. HindAA'ing: 
ATeins 6+7 on a long stalk, 8 united AA’ith the cell almost to the middle. 
S. albifasciata Hmps. (8 1). EoreAving golden broAAui, AA'ith a AAliite radial band in the loAA'er half of the 
cell and above vein 4, bent up to the apex shortly before the distal margin, darker broAvn before it. HindAAing 
purely AA+ite. $ 38 mm. Cape Colony, Natal. 
30. Genus: Hacleiiella Hmps. 
Proboscis normal, ])alpi short, porrect. Erons Avith a projection. Antennae of ciliated. Metathorax 
A\ith a tuft, abdomen Avith a tuft at the base. Neuration of foreAvung normal, veins 6 + 7 of hindAAung stalked 
in the generic type. Vein 5 beloAv the middle of the cross-vein. Type: pergentilis Grote from America. 
H. rectiradiata Hmps. (8 1). EoreAving light violettish-grey AA'ith broAAm radial blotches. More distinctly 
dark streaks at the margin beloAV the costal margin, in the middle, and above the inner margin. Ring-macula 
large, Avdiite; reniform macula small, Avith a dark median streak. A Avhite spot at the interior angle. HindAving 
broAvnish-Avhite. $ 22—-24 mm. Natal, Betchuana Land, East Africa. 
31. Genus: Chiriplia Wkr. 
Similar to the folloAA'ing genus, but the d antennae shortly pectinated, dentate apically. Thorax AA'ith 
a tuft in front and behind. Type: involuta Wkr. from India.
