PHEOSIA; MICROPHALERA; NOTODONTA. By M Gaede. 
vivida. D. chaonia Hbn. (Vol. 2, p. 297, pi. 45 e). —- vivida Zerny is a more extreme form of lunula Grunbg. 
Iii typical vivido.i also the inner part of the median area is white, but the dark central line penetrates right 
through. Further the margin is white from the pale subterminal line to the checked fringes. Hindwings white 
argentea. with indications of a dark band at anal angle and at apex. — argentea Class is “pale grey-white and faintly 
illunulata. marked . - - illunulata Did. is described as “pale specimens that would otherwise be classified with albisignata, 
albisigna- but with absent cell spot”. — This albisignata Lenz is widely white on forewings before the outer dentate 
line. This occurs predominantly in the $ sex. Probably differs little from lunula Grunbg. (Vol. 2, p. 297, 
pi. 45 e), in such specimens as w r ere mentioned by Grttnberg, where the dark intermediate marking is ab¬ 
sent. — A pair in the Pungeler collection is white at base of forewings before the basal line and similarly 
between the white margins of the inner and outer lines. Both these usually dark lines are absent and also 
the central line, which is still present in vivida. On the other hand the marginal area remains dusky. We 
are illustrating the $ of the vivida aberration (14 f). 
powelli. D. powelli Oberth. (15 e). I am including this species here, which was described as Hypocampa (Ho- 
plitis), despite the fact that the antennae are not pectinated right to the tip. Its place is certainly not under 
Hoplitis, whilst it has certain resemblances to chaonia. Ground colour similar to same. The subbasal line is 
less oblique and the space before same yellowish grey. A clearly marked black central line, slightly incurved. 
From same to somewhat beyond the dentate postdiscal line again yellow-grey. There is no trace of a paler 
subterminal line. Hindwings are grey-brown and the subdivided dark mark at anal angle reminds one some¬ 
what of that of milhauseri. $ 42 mm. Lambese. 
ntermedia. D. trimacula Esp. (Vol. 2, p. 296, pi. 45 f). — intermedia Schaiv. denotes a form with wide wdiite 
central band, i. e. like the type form from Mostar, but having the margin and base pale grey. In typical 
specimens of trimacula these patches are a yellowish grey, in dodonea they are blackish. 
D. basalis Wilem. & South (15 e). Similar to trimacula and with the brownish ground colour of same. 
The pale prediscal line consists of 3 curvatures, obliquely outwards and in a straight line. In trimacula it is 
somewhat excurved in the centre. The dark patch of the discal area is more indefinitely outlined against 
the paler patch. The width of the two patches presumably varies somewhat. The pale postdiscal line is 
narrower, clearer and more dentate. At vein 4 it is scarcely angulatecl but proceeds straightly to the sub- 
median fold and is more definitely angulated below same. The veins are finely marked with black in conjunction 
with the outer line. The subapical spot is narrower and more clearly marked. The marginal area is somewhat 
paler than the ground colour. Fringes are just as dark as those of dodonea or darker. On the grey-brown 
hindwings the hairs at inner margin are slightly reddish brown. $ 38 mm. Gifu (Japan), Sedanka (Ussuri). 
D. mandschurica Oberth. (Vol. 2, p. 297, pi. 49 b). This was classified in Vol. 2, p. 297 as the last species 
of the Genus Drymonia, but according to a specimen in the Pungeler collection, it certainly does not be¬ 
long here. Antennae of the G plumose, palpi short. In forewings vein 3 and 4 separate, 5 situate far in front, 
6 from centre of accessory cell, 7 with short stalk and with 8 + 9 from tip of accessory cell, 10 arising 
shortly before same. In hindwings vein 3 to 5 as on forewings, 6 + 7 with short stalk. As the old illu¬ 
stration w r as inexact and also that of Oberthur might be better, we are giving a fresh illustration (14 d). 
18. Genus: I*lieosia Hbn. 
Ph. tremula Cl. (\ ol. 2, p. 298, pi. 45 f). Specimens from Thian-shan have the ground colour of forewings 
a purer white and this is also more extensive. On costa the central one-thircl is quite a pale grey and this colour 
scarcely extends to vein 5. Also hindwings are pure white. Specimens from Uralsk form a transition to this form. 
Ph. buddhista Pnglr. (Vol. 2, p. 298, pi. 49 c). The dark band on forewings is rather too dark in the 
illustration and the edges are a bit too clear-cut. — In a specimen from Ta-tsien-lu there are dark rays 
inwardly above vein 3—5, which conjoin with the lowest apical streak. On hindwings the dark anal patch is 
gclukpa. more prominent. The general impression reminds one somewhat of tremula. It is named gelukpa form. nov. 
Type in the British Museum. 
20. Genus: Microplialera Btlr. 
styxana. M. styxana Schs. Bodies and wings blackish brown and silky. At disco-cellular a finely marked jet- 
black line. Inner and outer lines dark grey. The latter excurved at costa, undulate. Before same on vein 1 
a short white streak and behind same on veins 2—4 fine grey striations. Traces of a pale submarginal line 
near the costa. Hindwings brownish white with dark band before the pale margin. 38—44 mm. Omei-shan. 
21. Genus: Notodonta 0. 
tristis. Ah ziczac L. (\ ol. 2, p. 300, pi. 45 g). tristis Masl. (- lapponica DM.) denominates small specimens. 
Centre of costa of forewings is not pale grey, but dark violet-grey. Outer area devoid of markings, dark grey- 
montion. brown. Lapland, Poland. — mention DM. The form from the Tyrol mountains is uniformly reddish yellow 
in basal and discal areas. The discal lunule is distinct, band markings diffuse.
