§. Hindwing beneath at the margin with a coherent, narrow, black marginal band or marginal 
line. M. marshalli. 
§§. Hindwing beneath at the margin between the veins with triangular, yellowish spots bordered 
with black. 
1. The white subapical band of the forewing is large and touches the reddish-yellow spot 
of the posterior margin at vein 4. Expanse of wings: 60 mm. M. costleyi. 
2. The white subapical band of the forewing is smaller and does not reach the spot of the 
posterior margin. Expanse of wings: 50 to 54 mm. 
a. Subapical band of the forewing straight and coherently formed of 4 spots of the areas 
4 to 6 and 9. Area 2 without a white submarginal spot. M. slcoptoles. 
b. Subapical band of the forewing at vein 6 almost interrupted; its spot in area 4 puncti- 
form or indistinct. A white submarginal spot in area 2 near the reddish-yellow spot 
of the posterior margin. M. gelinia. 
B. Hindwing above at the base black and then with a yelloiv or reddish median band and black marginal 
band. 
a. Hindwing beneath with an equally broad, yellow median band separating the black-spotted basal 
area from the radiantly black marginal part. 
*. The spot of the posterior margin of the forewing plain, leaving above the discal cell free. 
1. Median band of the hindwing above about 8 mm broad, towards the base indistinctly defined. 
The spot of the posterior margin of the forewing posteriorly strongly expanded, almost reaching 
the base of the areas 1 a to 3. Subapical band of the forewing purely yellow. 
M. poultoni. 
2. Median band of the hindwing above only about 5 mm broad, sharply defined. Subapical 
band of the forewing ochreous-yellow. M. neavei. 
M. flavofasciata. 
**, The spot of the posterior margin of the forewing separated by black transverse streaks of the 
areas 1 a to 3 into an almost equally broad distal part and a proximal part formed of spots at 
the base of the areas 1 a to 4 and in the discal cell, M. lerausei. 
(3. The hindwing beneath without a yellow median band, but in the marginal part with very long light 
and dark rays reaching or nearly reaching the discal cell. M. masindae. 
M. pulverulenia. 
M. graeseri. 
M. charmian Smith <£• Ky. (62 b). Forewing above black with a curved reddish-yellow transverse 
band beginning at the costal margin somewhat behind the middle, extending behind the apex of the discal cell, 
leaving free the base of the areas 1 a to 6 and being expanded in the areas 2 and 1; beneath like above, but 
with a yellow transverse band and an apical part traversed by light and dark rays. Hindwing above reddish 
with a narrow, black marginal band tapering anteriorly and posteriorly, and a somewhat darkened base; 
beneath with a red-brown basal area spotted black, reaching the small discal dots, and outside of the latter 
with very long, light and dark rays. Cameroon. 
M. laeta A. Schultze (62 c) is very closely allied to the preceding species, but it deviates by the very 
extensive reddish-yellow transverse band of the forewing, being distally almost uniformly rounded, covering 
the base of the areas 1 to 3 and 8, extending even into the discal cell, and reaching the costal margin in 10 and 
11; ,,of the basal part of the black ground-colour thus only remains a slight dusting at the base of area 1, 
the greater anterior part of the discal cell, a spot outside distinctly defined in area 4, reaching the discal cell 
anteriorly as well as the distally sharply defined base of the areas 5, 6, 9 to 11 and the basal third of the 
costal margin. Hindwing bright reddish-yellow, at the base with few, small black scales, and a similarly coloured, 
proximally irregularly dentate marginal band of an average width of 3 mm, disappearing posteriorly in the area 
1 c. On the under surface the species resembles M. fulvaria, but it shows the following differences: on the forewing 
the ochreous-yellow transverse band already in 3 reaches the distal margin and proximally in 1 or 2 the base; 
on the hindwing the light internerval rays are towards the base defined by small, black lunae distally opened. 
Expanse of wings: 48 mm.“ South Cameroon. ,,The small insect slowly and cautiously flies during noon round 
thin poles of the brush-wood in the openings of the primeval forest.“
