the underside of the forewing is cut off straight distally. — hewitsoni Doumet (26 d). The under surface with. heu-Usoui. 
sharply prominent, black eye-spots with yellow rings and white pupils, two of equal size on the forewing in 
cellules 2 and 5, and 6 on the hindwing in cellules 1 c, 2, 4, 5 and 6, of which those in cellules 2 and 6 
are the largest; in cellule 1 c are placed two eye-spots, of which, however, the posterior one is small or 
indistinct. Cameroons, Gaboon and Congo. — subocellata Bartel (26 c) only differs in the small, paler mbwdlatu.

M. bicolor Bartel (26 d) only differs above from hewitsoni in having the blue transverse band of the bicolor. 
forewing broader and placed nearer to the distal margin ; on the underside of the forewing the dark basal 
part is not cut off straight distally, but projects ventricosely distad, the distal area of the forewing is whitish 
and has only two small eye-spots (in 4 and 5), the large eye-spot in cellule 2 being entirely absent. In the 
hinterland of the Cameroons. 
A third similar species is M. nanodes Sm., which is unknown to me in nature, but according to the nanodes. 
description agrees with bicolor above; beneath the dark basal half is distally bounded by a narrow, light 
violet band; the marginal area on the underside of the forewing is violet-brown and has two small eye-spots 
in cellules 4 and 5 and a larger one in cellule 2; the hindwing with eye-spot also in cellule 3, consequently 
with 7 altogether, of which those in cellules 2 and 6 and the first in cellule 1 c are the largest. Is probably 
only a form of hewitsoni or bicolor ; the shape of the distal edge of the basal area on the forewing beneath 
is unfortunately not mentioned in the description. In the forests on the Aruwimi River.

from the middle of the costal margin to the hinder angle and enclosing the eye-spot in cellule 2 which shows 
through from beneath; the hindwing above unicolorus black-brown, at the anterior margin of the cell in the 
c? with a glossy elongate spot, which is almost entirely covered by the forewing; on the under surface this 
species differs from all others in having the slightly darker basal part distally bounded by a broad, sharply 
defined, almost straight, white transverse line; the eye-spots are black, with yellow rings and white pupils; 
there are 4 on the forewing (one in cellule 2 and three joined together in cellules 4—6) and 7 on the hindwing, 
of which two are in cellule lc; the first of these and those in cellules 2 and 6 are larger than the others. 
The larva is above quite naked and smooth, with very short, tine hairs on the sides, green with numerous 
dark transverse lines, which are interrupted by the upper lateral lines; at the hindmargin of each segment 
are placed 4 dark dorsal dots in a transverse line; the head is rough, finely granulated and fine-haired, with 
4 large black spots; behind on the neck there are two smaller black spots; the horns on the head are obtuse 
and have two dark rings; the anal fork is rudimentary and only consists of two obtuse protuberances, 
obliquely directed upwards; in the markings, the shape of the body and the horns on the head the larva 
strongly recalls a slug. Pupa unicolorous green with quadrate, very sharply angled cremaster.

M. iccius Hew. (26 d) is larger than the preceding species and above similarly marked, but with the iccius. 
transverse band of the forewing curved and posteriorly narrowed; the whole under surface is dark grey and 
is divided into four parts by three dark brown transverse lines; between the second and third transverse lines 
are placed the yellow-ringed and white-pupilled eye-spots; in the cell of the forewing there are three black- 
brown transverse streaks, of which the outermost is united posteriorly with the first transverse line; the first 
and second transverse lines are almost straight and parallel, the third on the forewing diverges posteriorly 
and approaches the hinder angle; the third on the hindwing is feebly curved at vein 5: just before the distal 
margin runs a dark brown undulate line. Old Calabar, Cameroons, Congo, Uganda. — ephorus Weyrn. only ephorus. 
differs in having the eye-spots on the under surface small or punctiform and is probably only a seasonal 
form of iccius. Cold Coast. In ab. transiens Bartel the blue band of the forewing is scarcely more than half transient.

M. sebetus Hew. differs above from the preceding species in the blue-violet transverse band of the sebetus. 
forewing not being sharply defined and reaching at most to vein 2; beneath the wings are marked much as 
in iccius , but differ in having the third transverse line absent on the forewing and on the hindwing irregularly 
angulated and indistinct ; the eye-spots are small. West Africa from Liberia to Angola. — una Plots (26 e) una. 
only differs in having a white dot in cellule 5 on the upperside of the forewing and still smaller eye-spots on the 
under surface. Gaboon. — kochi Griinb. is probably also only a form of sebetus-, it is described as follows; kochi. 
Upper surface deep velvety black-brown, the blue subapical band on the forewing reaching posteriorly to just 
before vein 2; the white dot in cellule 5 which is characteristic of una is entirely wanting; under surface 
olive-coloured, strongly mixed with brown; basal part of the hindwing white; forewing from the middle part.
