ROESELIA; ARCHINOLA; CELAMA. By D. A. Seitz. 
G3 
2. Genus: Koesella Hbn. 
In Vol. II, p. 45, in describing this genus, it was stated that at that time no Roeselia except two 
from Madagascar were known from Continental Africa. To the 50 forms of the genus known at that time many 
have been added up to this day (quite a number have been newly described in Vol. VI, p. 230 to 239), and 
in addition to them there are also 4 African, so that together with the two forms from Madagascar the genus 
now consists of 0 Ethiopian species known. The neuration has been dealt with at large in Vol. X, p. 110. 
Including a considerable number of species recently described from New Guinea the genus comprises more 
than 100 forms to-day. Still the genus is difficult to circumscribe, because its characterization is chiefly foun¬ 
ded upon the neuration which is frequently of no use as a systematic resource in the Arctiidae, already on 
account of the structural anomalies of the wings which are sometimes entirely distorted by scent-organs. 
Thus it occurred that specimens of one species ( lugens from Australia) were placed to different genera ( Urdba 
Wkr., Coe-sa Wkr.) by the same author, and that even the next author (Felder) who did not recognise the 
bisect, established again a new genus ( Toxoloma ). The separation of the Roeselia from the Nola is neither 
universally acknowledged (Kirby, Saalmuller uniting both), whereas Hampson separates them, combining 
here, partly contrary to his former dispositions, species from the genera Mecjanola, Callinola , Proneca, Evo- 
nima, Mimerastria, Cy photo psyche etc. 
R. in can a Saalm. (8 c). This rather strong species somewhat recalls a brightly coloured Kola chia, incana. 
but the fore wing instead of being chalk-colourd is intensely irrorated with brownish, the median costal-marginal 
spot extending farther into the forewing, of the antemedian and postmedian stripes there are distinct traces, 
and darker median shadows extend through the brown hindwing. Madagascar. 
R. bryophiloides Btlr. (= respersa Saalm.) (8 c) is smaller, greyer, the forewing shows 4 irregularly IryopMloi- 
running, nebulous transverse stripes. Madagascar. des ' 
R. infuscata Hmps. (8d). Size of the preceding, the basal half of the forewing intensely irrorated infuscata. 
and smeared over with dark brown; in the whiter distal half only scattered undulate markings are noticeable. 
Hindwing of a dull white. Mashona Land. 
R. melanostkta Hmps. (8 d). On the chalk-coloured forewing there are 4 complete and 1 incomplete, melanostic- 
deeply dentate transverse stripe, in the cell there is a distinct dark punctiform spot. The dark stripe in the ia ‘ 
marginal area encloses a chain of small white spots. Hindwing whitish. East Africa. 
R. crefacea Hmps. (8 d). Forewing chalk-coloured, only the antemedian and median, strongly curved cretacea. 
transverse streaks are distinct, the anteterminal streak being divided into different parts. Hindwing brown. 
Gold Coast. 
R. costiplagiata Hmps., from British Central Africa, is not dissimilar to the palearctic albula (Vol. II. costiptagia- 
pl. 10 c), but the dark markings are not so distinctly arranged as transverse bands through the wing, but they ia ' 
are more confined to the costal region; the median stripe only extends to the cell-end, and the apical region 
of the -—- the $ is apparently not yet found — is dark. 
3. Genus: A rcSiiiiohi Hmps. 
This genus is based upon a very small species discovered by Nurse in Aden. Separated from most of 
the Roeselia by the entirely stunted proboscis, from the Indian Zia by the longer palpi. 
A. pyralidia Hmps. (8 d). Grey, strewn with a darker brown. Only the straight antemedian transverse pyralidia. 
line and the postmedian line, which is curved S-like, are distinct. Hindwing pale brownish. South Arabia. 
4. Genus: Celania Wkr. 
With this genus w r e have dealt at large in Vol. II, p. 47, and Vol. VI, p. 239. From Africa about 20 
mostly very small forms are known now, some of which are very similar to the Indian species. One of the 
species occurring also in the Ethiopian Region, is the very variable C. squalida being distributed over the whole 
of the Old World. 
C. omphalota Hmps. (8 d) is very small and almost entirely white, only at the base, the centre omphalota. 
of the costal margin and at the distal margin slightly brownish. Two rows of nebulous dots denote the 
antemedian and postmedian transverse lines. Hindwing in the apical part feebly darkened. Congo, Nigeria. 
C. microlopha Hmps. (8 cl) is still smaller and whiter, the forewing only before and behind the centre microlopha. 
very feebly tinted yellowish-brown. West Africa (Accra).
