METANASTRIA. By Dr. K. Grunberg. 395 
M. aconyta Cr. (= quaclricincta F., opponens WJcr., trifascia Wkr., substrigosa Wkr., subparallela 
Wkr.) (34 c). Light brown, on the wings with a slight reddish tint, the forewing between the bands and before 
the marginal part very much intermixed with white scales, whereby these parts turn greyish; 2 prediscal and 
2 postdiscal transverse bands distally bordered with dark and converging towards the proximal margin, the 
former rectilinear, the latter in the <$ distinctly, in the $ more feebly curved. Of the irregular submarginal 
line only 2 small black spots close at the proximal margin are always distinct. In the $ the ground-colour of 
the forewing and the marginal part of the hindwing are sometimes very much darkened. Under surface with 
2 indistinct dark transverse bands extending across both wings. North India: Sikkim (Darjeeling), Bengal, 
Canara. 
M. deruna Mr. (34 d). Brownish-yellow, the darker prediscal and postdiscal line of the forewing edged 
with partly undulate blackish lines. Of the submarginal line 3 white, black-margined spots below the apex 
of the wing and some angular markings before the proximal margin are distinct. Java. 
M. nanda Mr. (34 b) differs from M. aconyta Cr. by the more strongly bent proximal postdiscal 
band touching the distal prediscal line at the proximal margin, and by the larger dark spots at the anal angle. 
Basal part of hindwing red-haired. Sikkim. Perhaps only a form of aconyta. 
M. latipennis Wkr. (= placida Mr., vulpina Mr., cheela Mr., fasciata Mr.) (34 b, c). The species is 
of a very variable ground-colouring and was therefore repeatedly described. If it occurred in Europe, it 
would certainly have caused the establishment of quite a number of species, and also here it seems to be justified 
in restituting at least 2 of the names as sufficiently characterized forms. The is mostly of a beautiful dark 
copper-tint, in the forewing with a distinct white discal spot or a more or less distinct ferruginous-yellow spot 
behind the base as well as 2 prediscal and 2 postdiscal, blackish, not always distinct transverse bands, the two 
latter generally distinctly dentate; the space between the two median bands and the marginal area exhibit 
a distinct grey hue. The series of the white submarginal spots distally bordered with black begins with a large 
spot at the proximal margin. The <$<$ occur also in a lighter, even light greyish-brown colouring, in which case 
the discal and marginal areas of the forewings are more distinctly grey than in the darker specimens. On the 
under sm - face both wings exhibit 2 nearing dark transverse bands, the proximal one of which in the hindwing 
extends exactly across the middle of the wing almost rectilinearly from the costal margin to the proximal margin. 
The are much larger than the Q,d\ dark or lighter greyish-brown. The transverse bands of the forewings 
and of the under surface are broader and more diffuse, in the submarginal spots the distal black spots are predo¬ 
minant. — An especially lighter form is grisea Mr., in which the whole forevdng and the costal part of the 
hindwing are densely intermixed with white scales, thus creating a monotonously grey tint only interrupted 
by the dark bands and spots. The abdominal hairing is also very light. — In variegata Mr. from Ceylon, however, 
the thorax is grey-haired, and the basal part of the forewing is lighter, whereas the abdomen and hindwings 
are darker. —- Larva at the thorax with dense, long lateral hairing, on the abdomen with basal lateral and dorsal 
hair-tufts of light and dark hair. Pupa on the broadly obtuse anal end with a corona of bristles. — In the whole 
of India from the Himalaya to Ceylon, Burma, Sunda Islands (Java, Borneo). 
M. fulgens Mr. (34 b). Allied with latipennis. The <$ bright dark copper-red, the forewing somewhat 
more slender with a more bevelled border, the white discal spot minute, like a dot. On the distal half of the 
proximal margin an extensive, bright dark yellow spot. The transverse bands irregular, dentate, blackish, 
and indistinct like the submarginal spots being in the middle confluent with the distal band. Sikkim. 
M. ampla Wkr. (= ferruginea Wkr.) (34 c). larger than in latipennis, copper-red, greyish-brown 
or dark brown. The white discal spot often small, punctiform, the light spot behind the base of the forewing 
usually distinct. Transverse bands and submarginal spots similar as in latipennis, the postdiscal ones somewhat 
more strongly dentate. Hindwing with 3 often indistinct dark transverse bands. Under surface of both wings with 
3 distinct, dark transverse bands, the proximal one in the hindwing exhibits on the median part a broad inden¬ 
tation proximally, whereby the species is easily distinguished from latipennis. The reddish-brown or greyish- 
brown attain a very large size (expanse up to 130 mm). The bands of the hindwings are generally very 
obsolete, those beneath also being less distinct. India and Sunda Islands, as far as the Philippines. 
M. lidderdalii Btlr. (32 d). light copper-reddish with a distinct white discal spot in the forewing 
and 3 dark transverse bands, the 4th (proximal one) for the greatest part quite indistinct. The submarginal spots 
rather dense at the distal band. Discal area between the two proximal bands and the marginal part behind 
the submarginal spots with a grey lustre. Hindwing without distinct bands, under surface in the forewing and 
hindwing with 2 indistinct dark bands. — In the $ of the typical form the discal spot is absent, whilst in the 
aconyta.
