URAPTEROIDES; ACROPTERIS. By M. Gaede.

Chr. prometheus Drap. is certainly only a bad specimen of croesus and the statement of its patria, St. 
Helena^, is wrong. 
2. Subfamily: Microniinae. 
The following subfamily contains only medium-sized and small species of a mostly very feeble structure, 
with a white ground-colour and a pale brown, rarely darker marking. 
This subfamily shows no external resemblance whatever with the preceding subfamily. The 5 genera 
represented in the Ethiopian Region are decidedly like Geometrids; in their habitus they recall either the 
palaearctic or Indian Ur apteryx, or certain South-American Saturnidae from the genus Asthenicha. 1 he African 
species are very closely allied to their Indian relations, thus Ur. malagasaria, (67 d) resembles a small Indian 
astheniata (Vol. X, pi. 72 a), Acropt. costinigrata (67 e) reminds us of the Indian striataria (Vol. X, pi. 72 d), 
Ur. fasciata (67 d) of the Indian eaudiferaria (Vol. X, pi. 72 c) etc. 
Nothing particular is known of the larvae. The imagines, wherever they occur, are mostly very common, 
like to fly to the light, and in daytime they rest on leaves with their wings spread and sometimes very slightly 
raised (similar to Urapteryx sambucaria): on being scared up they only fly few yards. The colouring of all the 
African species is more or less white. 
1. Genus: IJrapteroitles Mr. 
Palpi short, porrect, antennae of thickened, of $ plain. Forewing broad, veins 3-j-4, 6 + 7, and 8+9 
stalked. Hindwing with a short, broad, small tail at vein 4. In the Indian genotype: asteniata Gn. veins 3 + 4 
of the hindwing are stalked, not so in the African species. 
U. falcifera Weym. (= recurvata Wrr., piperita Oberth.) (67 e). Forewing white with 3 pale brown falcifera. 
transverse lines from % anc l % °f the costal margin, all three extending obliquely distad. On the cross-vein 
a short streak. Hindwing with 2 lines from the costal margin at % and %, both nearing each other and dentate 
above the small tail. 45—50 mm. East Africa, Madagascar. 
U. malagasaria Mab. (= antsianakariae Oberth.) (67 d). Forewing white with 3 pale brown transverse malagasa- 
lines from %, y 2 , % of the costal margin. Hindwing with 2 lines, the distal one of which extends into the tail, TU 
the interior one being parallel with it. 50 mm. Madagascar. 
U. fasciata Mab. ( — suavis Oberth.) (67 d) is quite differently marked, slightly resembling an Indo- fasciata. 
Australian species of Cyphura. Forewing white. Costal margin narrow blackish-brown, apical area at about 
Y 3 of the length of the wing and towards the anal angle more narrowly blackish-brown. Hindwing at the tail 
with a brown spot, in front of it a broad submarginal band and behind it 2 spots blackish-brown. 40 mm. 
Madagascar. 
2. Genus: Acropleris Hbn. 
Palpi delicate, bent upward. Antennae of thickened. Costal margin of forewing bent, apex pointed. 
Veins 2+3 stalked in the + in the $ veins 3 and 4 from the cell-angle, veins 6 + 7, and 8 + 9 + 10 stalked. 
Hindwing at the base of the costal margin with a projecting lobe. For further particulars on the genus cf. Vol. II, 
p. 275. 
A. costinigrata Warr. (67 e). Forewing white, costal margin with black spots. Marking similar to the costinigra- 
Indian striataria Clerck. (Vol. X, pi. 72 cl). A straight faded shadow in the cell, a double line from y 3 and % 
of the inner margin, and a double submarginal line formed of streaks, united near the apex. Hindwing with 
an indistinct basal band, a broad median one and a narrow distal one, all of them formed of small streaks; 
behind them a dissolved submarginal band. Beneath: greyish-brown, $ white. 30—38 mm. Ogowe, Togo, 
Cameroon, Spanish Guinea. 
A. nigrisquama Warr. is likewise similar to striataria (Vol. X, pi. 72 d). Beneath there are black scales nigrisqua- 
at the base of the forewing, the distal margin is slightly pressed in. 34 mm. Niger District. In my opinion 
this may be the $ belonging to the 2 described of costinigrata. 
A. insticta Warr. is also similar to striataria (Vol. X, pi. 72 d). Distinguished by the absence of bands insticia. 
which are replaced by brown nebulous stripes. A broad stripe from y 3 , a narrow one from 2 / 3 of the inner margin, 
and a very narrow submarginal stripe. All of them meet near the apex. On the hindwing the third band is 
connected with the distal margin by irregular striation. 32 mm. 1 A from Madagascar. 
A. illiturata Warr. (= deprivata Pagenst., vacuata Warr.) (67 f). White with few pale brown scales, illiturata. 
Median vein of $ strongly bent forward, distal margin rounded. The 3 bands similar as in the species of
