M. argentifera Wkr. (90 c). Forewing brown, more or less dusted with silvery, with a dull silvery argentifera. 
postmedian line which is bordered by a silvery line distally on the inner margin (entirely so in the $). Margin 
with silvery vein-dots. Hindwing varying from ochreous to dark brown. Expanse of wings: 35—45 mm. 
Larva green, with large appendages in front and behind, both pairs connected at the base by a red transverse 
stripe, and smaller subdorsal and lateral appendages between the others; it lives on Musa. Ceylon, India. - 
kwangtungensis stibsp. n. is distinguished by the abdomen being entirely red-brown, without any silvery A wang- 
marking in the forewing, only the marginal dots being present in the $ (only in the centre of the margin in lun t/ensns 
the $), the $ sometimes with traces of the postmedian silvery marking. Hindwing not lighter than forewing. 
Dr. Mell captured the species in April, August and October in the Province of Kwang-tung. $ type from 
Tsha-yun-shan, $ type from Lo-fao-shan (Berlin State Museum). 
M. metathermistis limps. (90 c) is similar to argentifera, margin without silvery dots, postmedian line metha- 
more intensely spotted silvery above the inner margin which is yellowish basally. Body yellow, forewing tlwrmishs 
brownish-red, with a dark cross-vein spot and postmedian line on which there are single silvery scales and 
which extends from vein 6 obliquely to the centre of the inner margin. Marginal line brownish-red. Hindwing 
red-brown. All the fringes with a yellow basal line. Expanse of wings: 30 mm. Bombay, Kanara. 
M. thermistis limps. Body light red-brown, vertex and tegulae yellow. Eorewing light red-brown, thermisiis. 
the spaces between the veins in the centre of the wing scantily scaled, a brown spot beyond the cell-end, and 
a feebly bent postmedian line. Hindwing red-brown. Expanse of wings: 24 mm. — Larva green, with a blue, 
black-edgecl dorsal stripe, 2 black spots at the anterior end and 4 black spots at the posterior end, on Buck- 
landia. Cocoon underneath a transparent paper-like web. Assam. 
M. exigua sp. n. (90 c). Antenna of with pectinations gradually decreasing in length towards the cxigmi. 
end. Forewing pointed, with an almost straight margin, broadly dull violettish silvery in the costal-marginal 
area and at the distal margin, ground-colour reddish-brown, reddish-ochreous at the inner margin below 
the cell as far as %, the indistinct postmedian line is followed by an ochreous zone, cross-vein with a dark 
brown transverse streak. Hindwing ochreous. Under surface ochreous, with brownish ochreous costal-marginal 
edges. Expanse of wings: 30 mm. Naga Hills, July—August, 5000—8000 feet. <$ type in the Tring Museum. 
M. sola Swh. Chocolate-brown, forewing with a gilt area at the base, bordered by a pale line from sola. 
the centre of the coital margin to the tornus, where it is united with a brown submarginal band bearing off¬ 
shoots towards the margin, this band likewise with a golden tinge. Cross-vein dot and hindwing dark brown. 
Head orange. Expanse of wings: 34 mm. Borneo. 
M. pyronota Hmps. (90 c). Head and thorax fiery red, abdomen yellow, with a slight red tinge, pyronola. 
Eorewing reddish-brown, somewhat lustrous silvery, somewhat fiery red and yellow on the basal half of the 
inner margin, some silvery scales at the upper cell-angle, and a triangular silvery spot distally to the lower 
cell-angle. A postmedian row of silvery vein-dots, marginal area scantily dusted silvery. Hindwing yellow 
with a reddish tinge and a thin silvery gloss. Expanse of wings: 38 mm. Ceylon. 
M. sibinoides sp. n. (90 c). Body dark brown, abdomen somewhat lighter, forewing dark brown, post- sibinoides. 
median line only marked at the inner margin with a slight violet shine. A pale golden spot outside at the 
lower cell-end, a similar dot below it on vein 2. Hindwing pale wood-brown. Expanse of wings: 36 mm. India. 
$ type from Kanara (British Museum). Separable from decedens (90 a) by the darker brown thorax and the 
absent postmedian line, from all the other species by the cellular spot not being purely silvery but pale golden. 
M. scotopepla limps. (= scotopipla Swh.). Body blackish-brown, strewn with silvery scales. Eorewing scotopepla. 
silky blackish-brown, strewn with silvery scales, posterior edge of cell and basal half of vein 2 reddish; a black 
streak at the cell-end, marginal area somewhat more brown. Hindwing blackish-grey, marginal area more 
brown. Expanse of wings: 28 mm. Sikkim. 
M. sobrina Drc. Eorewing dark brown, with 2 darker brown transverse lines, the first zigzag-like near sobrina. 
the base, the second beyond the centre. Hindwing pale brown, paler at the base. Body dark brown, abdomen 
reddish-brown, abdominal end darker. Expanse of wings: 38 mm. New Caledonia. (It probably does not 
belong to this genus.) 
M. canescens Hmps. (86 g). Body light brownish red. Eorewing silvery grey, with a slight reddish tinge, canescens. 
strewn with black scales. An indistinct reddish-brown line from the costal margin before the apex to the inner 
margin before the centre, an indistinct bent reddish-brown subterminal line from the costal margin to vein 3. 
Hindwing pale yellow, fringe brownish-red. Expanse of wings: 32 mm. Ceylon. — This species exhibits 2 pair 
of spurs on the hind tibia, vein 10 of forewing arises after 7 from the stalk of 8 + 9, for which reason another 
genus woidd have to be established for this species; it may be that also sobrina. and some of the following 
species belong to it. 
M. brunnea Smpr. (90 c). Unicoloured red-brown, forewing dusted somewhat darker in the cell and brunnea. 
between the veins 2 and 4, hindwing blackish. Expanse of wings: 17 mm. — Larva dark violet above, with 
a white longitudinal line, sides and ventrum dingy yellowish, green between them, striated white, with yellow, 
black-spined appendages; on Cassia. Philippines.
