OCINAROPSIS; ODONTOGAMA. By Dr. C. Aurivillitts. 
much shorter and equally long almost to the apex. Femora and tibiae hairy; tarsi with appressed scales. Margin 
of both wings at the ends of the veins dentate or notched. Hindwing at the end of the discal cell with a hyaline 
spot. Costal margin of hindwing in the centre deeply emarginated. Forewing: veins 4 and 5 separate, 8 from 
the apex of the discal cell or from the pedicle of 6 and 7, 9 and 10 shorter than their pedicle, 9 into the distal 
margin. Hindwing: veins 4 and 5 separate or forked from the anal angle, 8 touches 7 in one place; basal 
cell small and narrow with basal accessory veins. Type: ,,Gastropacha il ’ knoblauchi Deiv. 
knoblauchi. M. knoblauchi Dew. (35 a). Red-brown; discal area of forewing and basal portion of hindwing darker 
brown; marginal area in the <$ lighter, greyish-brown. Discal spot of forewing yellowish without white dots; 
the subbasal transverse line is almost smooth and erect; the discal line is slanting, almost parallel with the 
distal margin, feebly undulating; the submarginal line of the forewing is coherent, in the areas 4 and 5 deeply 
bent towards the base. Hindwing at the end of vein 6 with a long sharp apex, above with two transverse 
lines; the hyaline spot rounded off. — The larva is, according to Tessmann, 8 to 10 cm long, with reddish hair 
exhibiting laterally on the rings a slight silvery reflection, the hair being extremely long, silky fox-coloured. 
Head dark fox-coloured. On the head two shorter tufts. Pupa fastened on trunks and branches. Cocoon tenacions. 
Cameroon to Congo. 
tripundata. M. tripunctata Auriv. (35 a) is much smaller and darker than knoblauchi. Dark greyish-brown, 
median area of fore wing a little deeper brown, bordered by two notched dark lines, the proximal one of which 
is transverse, the distal one very slanting; at the end of the discal cell a brownish-yellow spot decorated with 
three white dots. Hindwing at the end of the discal cell with a rounded hyaline spot and close behind the 
latter with a dark, notched and strongly curved transverse line being distally bordered with light; this 
transverse line is beneath more distinct than above. Hindwing at the end of vein 7 as well as of vein 6 with 
a long tooth. $ unknown. Nigeria. 
gerstaeckeri. M. gerstaeckeri Dew. (34 f). Body and wings with a pure ashy-grey ground-colour; discal area of 
forewing above quite or for the greatest part rust-coloured brown or at least with such a discal spot; this spot 
often shows in the $ three white dots. Transverse lines notched or the subbasal one only undulating; the 
submarginal line is represented by separate dark spots and often interrupted by the absence of the spots in 
the areas 4 and 5. Hindwing only at the end of vein 6 with a long tooth. — Cocoon large, oblong, 
posteriorly pointed and scantily clothed with black stings. The larvae live in colonies; then' hairs are highly 
developed burning hairs. Nigeria to Congo. 
cinerascens. M. cinerascens Holl. is closely allied with M. gerstaeckeri in its size and the shape of its wings, but 
it has monotonously ashy-grey wings without the brown discal area of the forewing. The pupa is relatively 
long, black, smooth, and without a cremaster. Expanse of wings: q 65, £ 95 mm. 
bnjki. M. bryki sp. n. (40 c). Similar to the of M. gerstaeckeri, but smaller, much darker, blackish- 
grey, and particularly distinguished by the upper surface of the forewing, the marginal portion of the hindwing, 
and partly also the thoracal dorsum being strewn with yellow scales (which are very distinct under the lens). 
Fore wing with a hyaline spot at the end of the cell, with dentate transverse lines being filled or bordered with 
yellow, and a very indistinct submarginal line composed of black spots. Abdomen above black and blackish- 
grey with yellowish hairs. Expanse of wings: 50 mm. Elgon; captured by F. Bryk. 
25. Genus: Ocinaropsis Auriv. 
Palpi stout, projecting beyond the frons; last joint short, pointed. Antennae in both sexes with almost 
equally long pectinations which are much longer in the basal portion. Tarsi with appressed scales; anterior 
tibiae unarmed; posterior tibiae without spurs. Fore wing narrow; its distal margin at vein 5 feebly angular; 
veins 4 and 5 rise separately, 8 from the pedicle of 6 and 7, 9 and 10 much shorter than their pedicle, 9 into 
the distal margin. Hindwing: costal margin long, almost quite straight; apex rounded; distal margin as far as 
vein 2 almost straight, at this vein with a short apex and somewhat angular; veins 4 and 5 rise from the same 
place or very shortly forked. 
obscura. 0. obscura Auriv. (35 b). Dark blackish-grey ($) or blackish-brown (<^). Thorax and forewing in the 
$ hued with reddish. Forewing above with a tiny white discal dot and with a double submarginal row of 
indistinct black and yellowish dots. Hindwing lighter grey, in the anal region blackish. Expanse of wings: 27 to 
33 mm. Natal (discovered by G. F. Leigh). 
26. Genus : Ocloiltogailia Auriv. 
Neuration quite the same as in the genus Taragama and only distinguished by the obtusely dentate 
or angular distal margin in both wings. Distal margin of forewing between the veins 2 and 5 emarginated, and 
angular at these veins; distal margin of hindwing at the anal angle and at the end of the veins 2 and 3 obtusely 
lobate or dentate.
