NYCTEMERA. By M. Gaede. 
seriatopunc- margined with black. At the hind-margin yellowish. Abdomen grey with black dots. 42 mm. — - seriatopunctata 
talci. A UTm (18 g) is smaller (38 mm); on the abdomen 2 rows each of black dots. Subapical band of forewing narrower. 
Ground-colour of hindwing purely white, not yellow. Congo. 
Group II. Hind leg,s of abnormal. 
insularis. N. insularis Bsd. greatly resembles rasana, but it is separated by the grey abdomen being above spotless 
proletaria. with a fine yellow lateral line. — In proletaria Strd. (18 g) the white subapical band also covers the whole central 
virgo. area. - virgo Strd. (18 h) may be a very extreme form of it. Ground-colour white, the subapical band indicated 
as a hyaline spot. Hindwing hyaline, at the margin narrowly white, more densely scaled. Without any marking. 
Madagascar. 
consors. N. censors Btlr. The subapical band is said to be more obliquely placed than in insularis, reaching 
the distal margin. Hind wing more broadly margined with black. Johanna I. A doubtful species which may 
be identical with seychellensis (IS f ). 
apicnlis. N. apicalis Wkr. (= fuscipennis Wallgr., antinorii Oberth.) (18 h). Thorax and forewing blackish- 
brown, between the veins black streaks. The subapical band is broad, with undulate margins. Hindwing with 
tricolor, a rather broad margin. — tricolor Fldr. has mostly a narrower subapical band which is more or less orange. 
persecta. A transition to it is bicolor Strd. ■ —- persecta Strd. The rather narrow white subapical band extends to the distal 
communi- margin. — communicata Strd. is a transition to it. As to gigantea, liliputana, albiciliata, and albinotica Strd., 
ca/a ' it suffices to mention them. — From the similar leuconoe the type is easily separable by the latter lacking the 
dorsal dots, and the intense yellow lateral line. 35 to 55 mm. Distributed almost everywhere in Ethiopian 
Africa. 
The following species are very large. 
acraeina. N. acraeina Drc. (18 li). Forewing similar to a large apicalis. Hindwing brown with a rather narrow 
pulverata. white median band behind which the ground-colour is lighter. — pulverata Strd. has a broader subapical band, 
togoensis. distally powdered with dark. - — togoensis Strd. has a narrower subapical band, but in the hindwing a broader 
auricolens. median band. -— auricolens Strd. has a narrow subapical band which is particularly proximad dentately defined. 
On the hindwing behind the typical median band no light area. In transitoria Strd. this lighter area is someAvhat 
more reddish than in the type. 60 to 70 mm. Togo, Cameroon, Spanish Guinea. 
chromis. N. chrortiis Drc. (18 c). Forewing as in acraeina though somewhat lighter. Hindwing as far as beyond 
tes&manm. the cell yellowish-brown, margin blackish-brown. -— lessen arm i Strd. (18 c) shows the subapical band proximad 
more dentately defined. On the hindwing the central area is intensely darkened. 65 to 70 mm. Cameroon, 
Spanish Guinea. 
usambarae. N. usasnbarae Oberth. (18 li) by the powdered subapical band resembles pulverata Strd. Hindwing 
white with a narrower black marginal band, proximad not sharply defined. 60 mm. Usambara. 
arieticomis. N. arieticomis Strd. (18 h). In the forewing similar to usambarae. The margin on the hindwing is 
only half as broad, with long rays on the veins. Beneath on the forewing below the cell as far as the hind- 
sulpliurana. margin of a pure white. -— sulphurana Strd. has yellowish-white, instead of white hindwings. 60 mm. Cameroon. 
Group III. All the legs of the normal. 
biformis. N. biformis Mob. $ (19 b). Fore wing smoke-brown, in the central area diaphanous. Hindwing in the 
central area narrowly white, diaphanous, otherwise also smoke-brown. Abdomen blackish. $ (= mabillei 
Btlr.) white. Forewing at the costal margin narrowly, in the apical area broadly, and at the hind-margin rather 
broadly blackish-brown. Hindwing narrowly black-margined. Abdomen white. Antennae of $ with short 
combs. 
The following species are very much alike, with finely dentate $ antennae. 
simplex. N. simplex Wkr. ( = xanthura Plotz, glauce Fawc.) (19 a). Forewing with a broad, curved, dark marginal 
band, the central area in the powdered with dark, only the veins being light. In the $ the central area is 
white without the radial basal lines of druna. Hindwing white, with a narrow black marginal band. Abdomen 
serrimargo. grey, dotted black. — serrimargo Strd. $ has a very narrow dentate margin on the hindwing. — paucipuncta 
paucipunc- yq /Y /. YS said to exhibit fewer dorsal dots. Cameroon, Togo, Sierra Leone. 
ta. ° 
ratirayi. N. rattrayi Swh. Forewing pale smoke-brown, in the central area thinly scaled and therefore lighter. 
Hindwing white with a narrow blackish-brown margin. Abdomen white with black dorsal dots. 35 mm. Uganda . 
druna. N. druna Swh. (19 a). Forewing white, at the costal margin narrowly blackish-brown. The dark 
distal margin is uniformly bent. Above the hind-margin some dark radial stripes. Hindwing white, margin 
narrow, rather equally broad dark. 40 mm. Ogowe.
