the cross-vein an incomplete black V. Below the lower cell-angle a horseshoe-shaped dark spot, outside white- 
edged. Exterior line black, as far as vein 6 oblique, then straight to vein 2. Before the margin white streaks 
between the veins and dark marginal dots. Fringe speckled. Hindwing lighter. $ 26 mm. Transvaal. 
M. diodonta Hmps. (78 h). Body greyish-brown. Forewing brownish white, at the costal margin with 
blackish-brown dots. Interior line traceable. In the middle of the inner margin an irregular dark spot. At 
the two angles of the cell dark lines. Exterior line strongly dentate, band-shaped. Hindwing brownish-white. 
The 9 on both wings browner. 20—24 mm. East Africa. 
M. leucostigma Hmps. Body blackish-brown. Forewing brownish white, suffused with blackish-brown. 
Recognizable by a large elliptical white spot below the cell from near the base to vein 2, below black-edged. 
An oblique faded finely dentate black line from the apex to above the centre of the inner margin. Before and 
on the margin a series of black dots. Hindwing greyish-brown. Fringes of both wings speckled. $ 36 mm. 
Basutoland. 
M. sticticosta Hvvps. Body and forewing greyish-brown. Costal margin intensely spotted black. At 
the base a black narrow loop. Exterior line oblique, below vein 5 somewhat excurved and outside faded, at 
the inner margin on both sides with white scales. Before it at the inner margin a brown, white-edged spot. 
Before and at the margin small dark spots. Hindwing greyish-brown. £ 34 mm. Natal. 
M. iridescens Janse differs from sticticosta in the longer stalk of veins 8 + 9 in the forewing, vein 8 
of hindwing not being connected with the cell by a bar. Thorax silvery white. Abdomen and both wings 
cinnamon brown. Costal margin of forewing spotted. In the centre of the cell some black dusting, behind it 
white scales. Above the centre of the inner margin an irregular spot, anteriorly rounded, black-edged, at the 
base broader. Exterior line black, from the costal margin inward, as far as vein 5 broad, then narrower, 
before it white scales. Marginal area white-scaled, at the ends of the veins large dark spots. Hindwing with 
a dark hue. J 38 mm. Ti’ansvaal. 
M. tuckeri Btlr. looks exactly like a Psychicla and was also described so, besides conspicuous for the 
large spur of the anterior tibia and the stunted palpi. $ dark brown. Forewing with a bilobate black spot 
at the centre of the inner margin. Hindwing at the apex copper-brown. 9 somewhat less dark. 10 lin. Natal. 
Larva on Cryptocarya woodii and Oestrum aurantiacum. 
12. Genus: Arbclodes Karsch (non Hmps.) 
Fore wing with a straight costal margin, inner margin S-shaped. Veins 7 + 8 + 9 from the apex of 
the accessory cell, 10 from its anterior edge. In the hindwing vein 8 anastomoses with the centre of the cell, 
6 + 7 are stalked. Antennae of $ with very long pectinations (longer than in arcifera), in the 9 short-combed. 
Type: meridialis Karsch. 
A. meridialis Karsch. (78 h). Greyish-brown. Forewing at the costal margin with black dots from which 
indistinct dark transverse lines extend. At the inner margin behind the centre a dark brown erect spot almost 
to vein 2, behind it a white spot to vein 2, before it only some white scales. At the ends of the veins dark 
brown dots, the margin before it narrowly greyer. Hindwing greyish-brown, without markings. In the 9 a 
dark nebulous band from the costal margin near the apex to the white spot at the inner margin. 25—30 mm. 
Cape Colony, Natal. 
A. collaris Aur. (78 h). Thorax and forewing blackish brown. Tegulae and patagia partly white. 
Forewing at the costal margin with a row of black dots as far as the exterior line. Basal area black, strongly 
excurved, white-edged. At the centre of the inner margin black, behind it white, in the cell a triangular black 
spot. Behind it as far as the exterior line light. The latter black, almost rectilinear, somewhat undulating, 
inside white-edged. Margin grey. Hindwing blackish-brown. 28 mm. Transvaal. 
A. heringi Janse. Thorax olive brown, tegulae and patagia white-edged, mixed with white scales. 
Fore wing olive brown. Costal margin broad white, with dark dots, especially in the apical portion, in the centre 
projecting a little proximad. Veins behind the cell partly white. Distal half of median vein and vein 2 below 
broadly silvery white, despatching a branch to vein 1, so that a T-shaped marking is produced, which may 
be somewhat interrupted. The interior third of the distal area behind the cell darker, often dentately defined. 
At the margin fine black dots, before them white partly confluent dots, before them a few larger black ones. 
Hindwing greyish-brown. $ 25 —26 mm. South-West Africa. Type in the Berlin Museum. 
A. griseata Janse. Similar to meridialis . Body and wings pale greyish-brown. Forewing at the costal 
margin dark brown. Exterior line faded, irregular, behind it light-edged spots between the veins. Below the 
cell near the base black dusting forming a V. Similarly in the cell-end and at vein 2 a V, in one specimen the 
black dusting is continued to vein 7. An oblique white line from the median vein to the anal angle. <§ 27 mm. 
Transvaal.
