M. puncticiilcta Holl. (3 c). The hyaline spots almost occupy the whole wings. On the forewing only puncticiru- 
the costal margin, a narrow stripe from the cross-vein and a marginal triangle at the tornus, and the apex, 
costal margin and distal margin of the hinclwing are narrowly black. West Africa. 
M. notoplagia Hmps. (3c). Thorax and basal half of abdomen marked orange; hyaline spots of notoplayia. 
forewing very large, in the hindwing only a median spot traversed by the veins. From the Gold Coast and 
Sierra Leone. 
M. ochsenheimeri Bsd. (= ponga Plotz) (3 c). Thorax orange with a black centre, abdomen orange ochsenhci- 
with a black apical part. On the forewing the dark patches extending towards the margin are broad, particularly 
the one at the lower median branch; apex of forewing broadly black. Hindwing with a broad blackish distal 
band. From the Congo. 
M. xanthopleura Holl. (3 c) differs from notoplagia in the anal half of the abdomen being orange- xanthoplcu- 
spotted, the basal half, however, black. Hindwing quite hyaline, only the costa and apex are quite narrow 
black. West Africa. 
M. xanthosoma Hmps. (3 c). Body quite orange-yellow, only the thorax marked dark. Wings quite xanthoso- 
hyaline, only from the cross-vein to the dark margin a narrow dark streak, and above the proximal angle 
a dark marginal triangle. Hindwing at the distal margin irregularly defined blackish. Uganda. 
M. blandina Oberlh. (3 c) is larger than xanthosoma. Body orange, marked dark. Forewing with blandina. 
large hyaline spots; easily recognisable by the orange-yellow hindwing showing a broad black apical area that 
encloses a small orange postcellular spot. From Madagascar. 
M. idda Plotz (3 d). Rather small, body orange, abdomen with black subdorsal lines. The hyaline idda. 
areas of the wings are large, that in the submedian space extending almost to the base. In the hindwing a 
large central hyaline area, all the margins dark, the hindmarginal edge orange. West Africa. 
M. vicforina Plotz (3 d) is larger than idda ; body dark, with a bluish-green reflection, not orange, victorina. 
Wings quite hyaline, in the forewing only the apex is broadly blackish, as well as a thin streak from the cross¬ 
vein to the margin and the space between the lower median branches. Hindwing likewise quite hyaline. 
Cameroon. 
M. nervalis Strd. is quite similar to victorina, but with a white frons, a white antennal apex, and a nervalis. 
small black apical spot of the forewing. Alen (West Africa). 
M. elachista Holl. (3 d) is one of the smallest species of the genus. Black, with a slight gloss, abdomen elachista. 
in the centre with a narrow yellow ring, forewing with a black margin, hindwing all black with small hyaline 
spots at the hind-margin and before the centre of the distal margin. West Africa. 
M. alluaudi Oberth. (3 d). In the forewing the hyaline spots are united into one large vitreous spot, alluaudi. 
like in elachista , but the basal and hindmarginal areas remain blackish-brown. Hindwing in the proximal half 
golden yellow, in the distal half black. Abdomen golden yellow, base, apex, and a narrow belt dark brown.

5. Genus: Tricliaeta Swh. 
Of the numerous species of this genus only 5 occur in the Ethiopian Region, the others being distributed 
over Southern India and particularly the Malayan Archipelago. As was already mentioned in Vol. X (p. GO), 
some African species also differ somewhat in the structure from the general type of the genus; for instance, 
the of pterophorina has a fissure below the apex of the forewing and plain antennae, fulvescens has fine short 
bristles on the antennal joints etc. As to further particulars about the genus cf. Vol. X 1. c. 
T. pterophorina Mob. (3 d). Forewing with yellowish hyaline spots, 2 of which are in the distal area, pterophori- 
1 large one below the cell, and 1 small one in the cell, being quadrangular in the $. Hindwing yellowish-hyaline 
with a narrow margin. The $ is at once recognisable by a fissure in the distal margin of the forewing, whereby 
the wing has the shape of a plume-moth (Pterophorus). Mashona Land. 
T. fulvescens Wkr. (= caffrariae H -Schaff., thyretiformis Wallgr.) (3d). With an orange abdomen fulvescens. 
and large hyaline areas on the wings; the hyaline spots in the cell and before the apex are very oblong. Hindwing 
with a broad brown distal margin and costal margin. From Cape Colony to the north as far as Congo and 
Natal. 
T. bivittata Wkr. (3 d) is smaller, with an orange body, marked dark; forewing brown with 4 not bivittata. 
very large hyaline spots. Hindwing hyaline with a blackish-brown margin proximally edged with yellow. West 
Africa. 
T. burtti Dist. (3 e), from the Island of Pemba (to the north of Zanzibar) is dark brown, the anal half burtti. 
of the abdomen orange. In the forewing the proximal spots are yellow, the distal ones white-hyaline; the 
hindwing is relatively large, quite brown, only on the centre of the hind-margin there is a large irregular yellow 
spot. The species has recently been mentioned as Syntomis. 
T. schultzei Aur. (3 e) is much smaller; abdomen orange; the proximal third of the forewing is schnitzel, 
hyaline except the margins, in the brown distal part there are 2 minute hyaline spots; hindwing hyaline with 
a narrow dark margin, Nigeria,
