WILEMANUS; MELAGONINA; ODONTOSIA; ODONTOSINA. By M. Gaede. 
S. nivea Mats. Forewings white with a few browm scales, veins yellowish. Near base of costa a row 
of blackish streaks and above the centre of inner margin a few black scales. Hindwings wdiite, yellowish 
at margin and on veins. Antennae and body yellowish, ochreous on upperside of abdomen near base A 
30 mm. South Saghalin. ' ° 
26b. Genus: Wilemanus Mats. 
Thorax like in Ochrosiigma. Palpi short, densely haired. Antennae of pectinated almost to their 
extremities, shorter pectinations in $. On forewings veins 3 and 4 arise separately, 6 laterally from the ac¬ 
cessory cell; 7, 8 + 9 and 10 separated from apex of same, vein 11 free. On hindwings veins*3 and 4 arise 
from same spot, 5 is more weakly, 6 + 7 with short stalk. 
W. bidentatus Wilem. (14f). The main form was erroneously described by the author as S taw opus 
and therefore enumerated in Vol. 2, p. 290 as such. On the other hand the form ussuriensis Pnglr was dealt 
with as Ochrosiigma in Vol. 2, p. 305, pi. 49 b. It differs from bidentatus by the absence of the bold black 
streak in the submedian fold, whilst on the other hand the black lunule at disco-cellular stands out more 
prominently. Ground colour of both forms is white-grey, coreanus Mats, is identical with ussuriensis. In 
Nanking the form bidentatus occurs and not ussuriensis, according to specimens in the collection of Hoene. 
We are illustrating one of these specimens.

Similar to Wilemanus. Thorax as in Ochrosiigma. At base of abdomen 2 small tufts. Palpi densely 
haired, somewhat longer than in Wilemanus. Antennae of $ pectinated somewhat nearer to extremity On 
fore wings veins 3 and 4 arise separately, 6 closely below upper angle of cell, 7 just below apex of accessory 
cell, 10 + 8 + 9 from apex of same. On hindwings vein 3 is somewhat separated from 4, 5 is weaklv 
6 + 7 with short stalk. 
hocnei. M. hoenei sp. n. (14 f). Somewhat like Ochrosiigma melagcna (Vol. 2, p. 305, pi. 45 c). Thorax and 
forewings greenish brown. The inner band with black edge and dusted with black. Its inner edge projects 
far below the cell, its outer edge about vertically at y 3 rd of costa, with small interruption above submedian 
nervure.. At disco-cellular a faint light streak. The finely drawn outer line is white, dentate and only dis¬ 
tinct at its commencement and extremity. Behind same on costa there is a triangular mark of dark dusting 
and a similar but quadrate mark on inner margin. The latter is outlined on upperside by a black line. Be- 
sides the inner band is intersected by a black line. Hindwings grey-brown. $ 40 mm. Nanking (Kiano-su). 
Type in the collection of Hoene. 
27. Genus: Odontosia Hbn. 
O. carmehta Esp. (Vol. 2, p. 305, pi. 46 g). nocturnalis Stick, is much darker than type. On fore wings 
tie otherwise extensive white dusting is only present as a faint grey hue at inner angle. As it is also 
described from Lapland, it will probably scarcely differ from the older nordlandica Strd. form ml 14 + 
saucrmanni. mentioned in Vol. 2, p. 306. An illustration of the latter is now being given here. - sauermanni O. Bang- 
Haas (14 f) is as uniformly dark as nordlandica, but as reddish brown as is otherwise only the costa. The 
pale grey colour is also concentrated at the anal angle, from below lower median nervure. Hindwings are 
fairly typical without the grey sheen. This form was bred. 
• S' sievers *‘ Mm. (Vol. 2, p. 306, pi- 46 g). Around Konigsberg and probably also throughout the 
Baltic Provinces a form is found that is dark in both sexes. In the $ forewings are black-brown, only the two 
transverse lines and a few spots near the margin are pale. In the $ marginal area is paler: strlngei Stick. 
IT In con trast to this there is the pale form grotei Stick, which is found everywhere among this species. 
It, has more profuse white dusting with reduced markings. In the cj the outer transverse line is completely or 
almost obsolete, marginal area very pale. In the $ only the costa and inner margin are pale brownish' all 
the rest is whitish, markings being very faint, schellenbergi Simla with indistinct and diffuse markings” 
is probably the same. — The indication in Vol. 2, p. 306 that the type form occurred in the Amur and 
Ussuri districts must be cancelled. There patricia Stick. (= arnoldiana Karel.) (15 e) occurs. According to 3 
specimens before me, it is larger than sieversi. The colour of forewings of $ is a dark reddish brown from 
costa to median nervure, as well as in the discal band. The yellowish lunular line at the outer edge of the 
discal area is more distmet. On hindwings the pale central line is longer than is generally the case in sieversi. 
lUe y also has obscurer markings and is similarly a darker brown than type. Vladivostock, Sedanka. — 
japombia Mats, will not vary much from same and a denomination appears scarcely justified.
