0. nigronervata sp. n. (15f). Thorax deep red-brown. Fore wings somewhat paler. Below the cell nigroner- 
and on lower median nervure to the outer line, darker, almost black on inner margin. Outer line black 
and dentate. Veins beyond same black. Below each of veins 4 and 6 a black spot. Abdomen of same 
shade as forewings. Hindwings somewhat paler brown. 40 mm. Tze-ku. Type in the British-Museum. 
28. Genus: liopliontosia 8t.gr. 
L. pryeri Btlr. (Vol. 2, p. 307) should be classified here and not with the Bophopteryx. It is very 
similar to cuculus Stgr. (Vol. 2, p. 306, pi. 46 d, 49 b), but differs in the shape of the prediscal line, which 
forms 3 arcs ; only the sinus below submedian nervure is identical in both species. The species is not similar 
to Oil. sieversi as seemed to be implied in Vol. 2, owing to the insufficient original description. It varies 
quite considerably. — japonica 0. B.-Haas denotes specimens having a pale basal area on forewings, the japonica. 
marginal area beyond the postdiscal line is dark whilst the margin itself is pale and distinct, similar to 
Boph. cuculla (Vol. 2, p. 307, pi. 46 h). 
L. draesekei O. B.-Haas. Similar to cuculus (Vol. 2, pi. 49 b), but the colouration is grey. The inner draesekei. 
line projects very far forward in the submedian fold, the central area is not paler. The postdiscal line is 
faintly angulated on vein 6 and in the submedian fold; it is white with a black inner edge. The discal and 
outer areas are dark and clouded. Tooth or lobe large, rounded and dark grey. Hindwings grey, paler at 
base. 30 mm. Peking. The species should almost certainly not be classified here.

and at base. The wide black-brown discal band excurved on vein 4 and terminating before the tooth or 
lobe on inner margin. In front of same widely dusky. The black-brown inner line is sharply dentate and 
only distinct on inner margin. Hindwings marked like the other species. 42 mm. Hokkaido. 
L. sounkeana Mats. Similar to robusta. Forewings of dark brown. The inner and outer lines are sounkeanct. 
wider, the radial streaks behind the cell are more numerous and prominent. Hindwings dark grey with usual 
markings, the black anal spot is wide. 44 mm. Hokkaido. 
L. nikkoensis Mats. yellowish brown, $ dark brown. Fore wings of with wide black-brown band nikkoensis. 
from centre of inner margin to near the apex on costa. Towards the base from this band, a few short black- 
brown radial streaks. Forewings of $ have a violet sheen. Anterior to the tooth or lobe there is a dentate 
black-brown inner line, which is only distinct on the widely dark inner margin. Thorax of <§ with ashy 
grey triangle, which is whitish in the Q. 44 mm. Nikko.

form by its striking grey colouration, also the body being grey. The name is not happily selected, as 
there is already a “species” grisea Brem. which only differs from european specimens, as so often happens 
in East Asia, by its size. — In the grey-brown lapponici Teich (14 e) it is stated in Vol. 2 that the pale 
“median band of hindwings is absent”. In the numerous <§ and $ of the Pungeler collection from Gelli- 
vare, the hindwings are almost white. We are giving an illustration of a <$. — obsctira Hoffm. denotes very obscura. 
dark specimens from cold localities. Also hindwings are grey-brown with grey-black margins. Except for 
the hindwing therefore it seems to be identical with lapponica. 
33. Genus: Ptilopkora Steph. 
P. plumigera Esp. (Vol. 2, p. 309, pi. 47 g). The pale and dark forms of this species have been 
denominated many times, pallida Hoffm. denotes pale buff specimens with reduced markings. — A pale pallida 
form with very faint markings has been named extincta Galv., berolinensis Strd. and pallida Closs. If is 
doubtful whether the latter two are distinct from the first named form. — The counterpart obscura Schwing. obscura. 
is a fairly uniformly blackish dusted form. — schaffgotsdii Marschner is described as dark grey, only the schaffgot- 
abdomen retaining the normal colour and besides there are a few sparse yellow scales on both wings. 
Intermediate forms are as follows: saturatior Phi. (obscura Gloss, plumigerella Strd.) is a striking reddish, saturalior.
