is the European quercus. In the marking the same, and also in the colouring similarly variable, but the anal- 
angular spots on both wings more intense and darker; the tint of the forewings is either earth-brown or bark- 
coloured, the hindwings are cinnamon-coloured. - On the whole the total colouring varies between sand-colour 
and a deep smoke-brown; particularly pale specimens in which the marking is also rather inconspicuous were 
called: plana Clark. — Specimens from Java and the Philippines, presumably also from other Sunda Is., as a plana. 
rule are deeper dark brown, with less grey on the forewing; this is javanica Btlr. (=- dryas Mr., dyras limps., javanica. 
sperchius Piep.). — Larva likewise quite similar to that of quercus, varying from a dull green or brownish-grey 
to yellowich-brown, coarsely granulated, with very straight oblique streaks which may be lighter or darker. 
Recognizable by a light stripe on the sides of the head, extending from the vertex to the mouth. On Stercu- 
liaceae (Sterculia, Biittneria aspera, Pterospermum heterophyllum); also on Grewia microcos. The imagines 
are rather common near the light. 
Mo andamana Mr. (62 a) is so closely allied to the preceding species that it was often regarded as the andamanu 
geographical form of it; it chiefly differs in the augmentation of the transverse stripes on the forewing, which 
is produced by the broad transverse bands of dyras not contrasting by the colour against the ground of the wing 
and exhibiting merely contours, which doubles their number. But also the ground-colour is more constant 
than in dyras , the forewings are darker and the hindwings more of a chestnut than cinnamon colour. Andamans. 
M. amboisiicus Fldr. (66 b) is likewise only a geographical representative of dyras ; more unicoloured amboinicu- 
dark brown, with a yellow tint; the dark distal area of the forewing is more extensive, the postdiscal transverse 
line above the anal-angular spot produced towards the margin and forming another sling. Southern Moluccas. —

shows a dentate margin of the forewing. rofhschildi Huwe, from Batjan, is somewhat smaller, the costal rothschildi. 
margin is more curved towards the apex, the distal margin somewhat more distinctly notched; the transverse 
lines through the disc — judging from the figure — seem to be more convergent towards the inner margin. 
M.nympha R.&J. is closely allied to amboinicus ; slate-coloured, with a light claret-coloured hue; nymphci. 
forewing with 4 transverse lines between the base and the apex of the cell, all rather straight, the 3rd and 4th 
nearer together than in the preceding species, with a white central spot, but without a dark streak on the cross¬ 
vein as gigas and juvencus show. The 4th line is not double, parallel to the 3rd; the anal median spot is surrounded 
by a line. Hindwing umber-brown, behind the darkest, in the anal portion with a grey hue. The subanal spots 
are separated. Beneath similarly coloured as above. From Karwar near Portuguese Goa in India. 
M. timora R. db •/., from Timor, resembles the following sperchius, but it is smaller, deeper coloured timora. 
and without the dark median stripe across the body. The distal transverse stripes through the forewing are 
also less prominent. Typical specimens from Timor show a more ashy grey base of the fore wing, and the 
marginal area is darker than the space between the discal and antemedian transverse lines. laoterssis R. <k J. laotcnsis. 
has quite unicoloured fore wings, and the hindwings are broader and have a rounder apex; Tenimber. The 
species is still rare in collections. 
M. sperchius Men. (= piceipennis Btlr., michaelis Oberth., dryas Orza, dyras Hmps. nec Wkr.) (Vol. II, sperchius. 
pi. 38 a). The species described in Vol. II, p. 241 chiefly occurs in the palaearctic region, but also in North 
India and South China; in Kwan-tung in the form handelii Med, which however may be only an aberration; handelii. 
it lacks the dark oblique streak at the anterior edge of the tegulae, the outermost transverse line in the disc 
is in front double, and the hindwing beneath exhibits between the thick antemedian line and the postmedian 
line another dull double line. - North-Indian specimens are considerably lighter owing to their bright whitish 
tint; these are albicans Btlr. — gigas Btlr. (= dyras Wkr.) (66 b), from Assam, is considerably larger than albicans.

very coarsely granulated white, with long thin light yellow oblique stripes in the sides. On oaks and chestnut- 
trees. — Apparently not common in the Indian region. 
M. scotti Rothsch. is most similar to gigas (66 b), but smaller, grey, without the sand-coloured or tan- scoiti. 
coloured tint. Besides another transverse stripe extends from the costa of the forewing across the stigma, 
meeting the 4th stripe on the submedian vein, where it stops short. The dark brown colour of the hindwing 
is suffused with grey, and the margin of the wing is less strongly notched. — Larva green, often very light, 
almost whitish, granulated white, sometimes with red-brown spots. On the front part whitish lateral stripes, 
on the segments 5—11 lateral oblique stripes. On chestnut and oak trees; the larvae were often found covered 
with flies which, however, had not infected them, since they yielded sound imagines. Assam. 
M. juvencus R. <£- J. (66 b) is very similar to sperchius, particularly to its form gigas, but smaller, and juvencus. 
the outermost transverse line of the forewing extends almost quite straight from before the apex into the 
distal margin below its centre. Borneo (Sarawak).
