N. ugandicola Strd. (19 a). at the costal margin of the forewing narrowly blackish-brown. The ugandicola. 
distal margin at the apex broader dark, so that the border-line goes beyond the base of vein 3 and an angle 
is produced above vein 2. In the $ the costal margin is not dark. Hind wing white, with a narrow uniform , 
dark margin. Expanse of wings: 35 mm. Uganda. — anomala Holl. may be a synonym of it. 
N. hemixaniha Aur. (19 a) is recognisable by the almost entirely yellow abdomen. The white ground- hemixan- 
colour is not so transparent as in the other species. On the forewing the proximal edge of the blackish-brown ,/ia - 
marginal band is slightly curved, therefore behind broader. <$ at the base of the wing with brownish rays. On 
the hindwing the dark margin in the S is narrow, in the $ frequently broken up into spots. This form is probably 
anomala Holl. 35 to 40 mm. Cameroon. 
N. itokina Aur. (= camerunica Strd.) (19 a) is quite different. Pale brown, thorax without white Ho kina. 
lines. Forewing with a narrow white subapical band; in the submedian fold faded or also distinctly light. 
Hindwing white with a broad brown margin. — In a specimen from Lake Victoria this margin is very narrow. 
25 mm. Cameroon. 
N. marcida Swh. resembles a large itokina (19 a). Abdomen black with white segmental margins, marcida. 
The streak of the submedian fold is on both ends pointed. 38 mm. Angola. 
4. Genus: Myi emera Btlr. 
Antennae of $ strongly pectinate. In the forewing vein 6 below the cell-angle, veins 7 + 8 + 9 forked, 
7 forming with 10 an accessory cell, 11 as a fork from 10 and 12. In the hindwing veins 6 and 7 not forked, 
8 near the base united with the cell. Type: tenuis Btlr. Most of the species in Madagascar. 
H. tenuis Btlr. White, semi-transparent. Eorewing at the base ochreous-yellow. The basal two fifths tenuis. 
are defined by a dark line which ends at the costal margin in a large black spot. At the cell-end a small black 
spot. Apex and distal margin broadly black. Hindwing with a small black spot at. the cell-end. Thorax black, 
abdomen white. 32 mm. Madagascar. 
H. Candida Btlr. Similar to tenuis. Snow-white. Forewing at the apex and distal margin broadly Candida. 
smoke-brown, proximad slightly angular; 5 white spots near the proximal edge of the marginal band. At the 
cell-end a smoky-brown spot. Base of wing ochreous yellow. 30 mm. Madagascar. 
H. puella Btlr. is silky white, semi-transparent. Forewing at the apex and distal margin broadly paella. 
blackish-brown, proximad forming an angle. At the base somewhat yellowish. Body greyish-white. 30 mm. 
Madagascar. 
H. nivea Btlr. is snow-white. Forewing on the cross-vein and at the apex greyish-black, therein a nivea. 
submarginal white streak. Base of wing saffron-coloured. 28 mm. Madagascar. 
H. fragilis Btlr. also resembles puella. A black costal patch on the forewing. Distal margin narrower fragilis. 
black than in nivea, strongly projecting at the veins. On the hindwing the cross-vein is not black. 30 mm. 
Madagascar. 
H. dexithea Drc. Forewing white. Apical third broad black, then the margin narrows down as far dexithea. 
as the anal angle. Hindwing white with a black dot at the apex. Thorax and abdomen yellowish white. 30 mm. 
Cameroon. 
H. melusine Strd. (19 b). Forewing white with a black marginal and costal band, similar to Girpa nolata melusine. 
Holl. Costal band narrower; the white spot in the marginal band is oblong, in front tapering. Margin of hindwing 
at vein 2 widened. All the black marking is edged with yellow. Thorax and abdomen orange-yellow. 30 mm. 
Upper Guinea. 
H. (?) fadella Mab. Forewing yellow, powdered with a greyish brown, more scantily in the central fadella. 
area, more intensely in the distal area which is set apart by a black, somewhat dentate line. Hindwing orange- 
yellow with a black margin. Body yellow. 17 mm. Madagascar. 
H. doleris Plotz, and the species neaera Drc., eurema Pldtz, and luteipes Mab., which were compared 
with doleris, are probably all Geometridae.
