scales, the black largely predominating; femora mostly clothed 
with dark scales, a few white, and with a white ring round the 
apex and a few black chaetae; there are also numerous out¬ 
standing parti-coloured scales, black at the apex; tibiae of fore 
legs with dense shaggy jet-black scales on the basal half or two- 
thirds, the apical portion with pure white scales; in the mid and 
hind legs the black scales cover the greater part of the tibiae ; 
metatarsi and tarsi of the fore and mid legs not densely scaled, 
thin ochraceous in colour; in the hind legs there are scales 
standing more or less from the surface, the basal ones, on the 
second tarsal and partly on the first, white; ungues equal, 
uniserrated, thick, more curved than in M. scataphagoides, not 
nearly so blunt and thick as in M. cilternans. 
Wings with broad spatulate scales, mostly parti-coloured, 
those on the fork-cells and apical half of the third longitudinal 
black ; there are also a few dark scales dotted over the other 
veins amongst the paler parti-coloured ones, especially along the 
costal and first longitudinal vein; fringe mostly dark, very black 
at the apex,- with five irregular-sized pale patches, two small ones 
near the apex, between the third long vein and the upper branch 
of the second posterior cell, a longer pale patch on each side of 
the upper branch of the fifth, and another rather faint one nearer 
the base of the wing; first sub-marginal cell considerably longer 
and narrower than the second posterior cell, its stem equal to 
about half the length of the cell; stem of the second posterior 
cell as long as the cell; cross-veins normal, the posterior rather 
nearer the mid perhaps than usual. 
Length .—7 to 7*5 mm. 
Habitat. —Asaba, W. Africa (Annett). 
Time of capture .—August. 
Observations.—A. number of this species have been sent me 
by Dr. Annett. It can at once be told from others of the 
genus by the simplicity of the leg banding, the tibiae being half 
black scaled and half white. The nude appearance of the fore 
and mid metatarsi and tarsi is also characteristic, whilst the 
ungues and wing scales clearly differ from the other species. The 
wing fringe and the black-scaled apices to the fork-cells and 
third long vein are also very noticeable characters. Although 
the scales somewhat differ in form from the type, yet they present 
the same general appearance, and the wing venation clearly 
shows the species to come in this genus. It appears to be 
common in parts of the west coast of Africa.
