M. constabilis Wilem. i. 1. ? (15 g). There is a pair under this name in the Pungeler collection. They 
are from Yokohama and resemble the reddish form of stabilis, with more sharply marked and paler subterminal 
line on forewings. The main difference from stabilis is in the stigmata. Orbicular is small and round, with pale 
circumscription and about as large as in the much smaller cruda. Reniform is narrower and more crooked than 
in stabilis. 
M. aoyamensis Mats, somewhat resembles the japonica form of stabilis. but has serrate antennae. Fore¬ 
wings grey-brown, sparsely peppered with black and with reddish brown transverse lines having paler edges 
on averted sides. The oval orbicular stigma is delicately circumscribed by yellowish and is indistinct. The 
large reniform stigma similarly with blackish centre in lower lobe. Between the two there is an angulated 
median line. Subterminal line is yellowish with dark shade on inner edge. Hindwdngs dark grey with obso¬ 
lete discal spot and yellowish fringes. Wing expanse: 44 mm. Japan (Hokkaido) in May and June. 
M. angustipennis Mats. Forewings dark brown, peppered with reddish. Transverse lines extinct with 
the exception of the yellowish subterminal line which has a reddish brown inner shade. The round obsolescent 
orbicular stigma with pale surround, the large somewhat dusky reniform stigma similarly has a pale circum¬ 
scription. Posterior to subterminal line, marginal area is widely paler. Fringes dark grey with paler base line. 
Hindwings of same shade as forewings. Wing expanse: 36 mm. Japan (Hokkaido). 
M. albolineata Mats. Forewings dark brown with obsolete dark transverse lines. The anterior line un¬ 
dulate, twice excurved, the posterior line oblique, barely undulate. The small round orbicular stigma is grey- 
white with dark surround, reniform yellowish white with similar black-brown circumscription, claviform distinct, 
deep brown. Veins dusted with black-brown. The narrow subterminal line snow-white with distinct “W” in 
centre. Hindwings dark grey, paler towards base, with white fringes and dusky brown discal lunule. Wing 
expanse: 34 mm. Hokkaido. 
M. pulverulenta Esp. (Vol. 3, p. 91, pi. 22 g). — nigropunctata Wehrli is a form with distinct dark 
transverse lines and dots. Described from Switzerland. 
M. fluvilinea Mats, has narrower forewings, grey with faint leaden gloss, transverse lines obsolete with 
exception of subterminal. The latter distinct, reddish brown with paler line outwardly. The round orbicular 
stigma with yellowish surround, the large reniform similarly, with slightly reddish centre. Apex faintly dusted 
with white. Hindwings dark grey with blackish discal lunule. Wing expanse: 32 mm. Japan (Hokkaido). 
M. nigrolinea Mats. Forewings grey, peppered with black-brown. Both central transverse lines ob¬ 
solete. The large oval orbicular stigma indistinct, slightly dusky with fine pale surround. It extends at top 
almost to costa, as does also the obsolete reniform stigma. The wide subterminal line is black and bold, inter¬ 
spersed with orange scales, terminating at top in a triangular costal spot. Fringes vellow-grey with dark divid¬ 
ing line. Hindwdngs grey with yellowish metallic gloss and obsolete dark subterminal- Wing expanse: 35 mm. 
Japan (Hokkaido). 
M. incerta Hufn. (Vol. 3, p. 91. pi. 22 h). Further forms of this exceedingly variable species have been 
described: fasciata Lenz with .dark median band, — obscura Lenz unicoloured brown, not sooty blackish 
like atra; — melaleuca Lenz unicoloured brown-black with stigmata with pale outlines and pale line before 
margin. - picata A. B.-H. somewhat resembles the form pallidior Stgr. from Ferghana, but apex of forewdngs 
is more pointed, it is not so greyish yellow, rather more unicoloured pale brownish, scarcely mottled and espec¬ 
ially the hindwings are much paler than in european specimens. From Karagai-tao. 
M. opima Him. (Vol. 3, p. 92, pi. 22 k). — virgata Lenz has very dusky median area. - obscura Lenz has 
additionally dark grey basal and marginal areas. — griseor Strd. denotes outspokenly grey specimens, with no 
suffusion of reddish in central area of forewings and with an indistinct median shade. — rufofusca Strd. are 
dark brown suffused specimens flushed with reddish hue. 
M. puengeleri Stfs. is classified close to populi (Vol. 3, p. 90, pi. 22 d) but the outer margin of forewdngs 
is rather more undulate. Colouration varies considerably from that of the other species, consisting of a mixture 
of greenish with pale and dark grey shades, similar to those of Polyploca ridens. Median and narrow outer 
marginal areas darker than the rest of the w ing. Transverse lines quite indistinct and only vestiges left. Orbi¬ 
cular stigma a somewdiat compressed oval shape with dark centre and encircled by a pale and very clear sur¬ 
round. Reniform stigma oblique, pale with alternate dark and pale surrounds, lower lobe with dark centre. 
Subterminal line is of peculiar formation, a faint. “S" shape with deeper concavity in centre, almost devoid 
of dentations. Heavy black spots on outer margin. Hindwings pale grey with faint subterminal shade. The 
A is of much more monotonous colouration than the $ which has very contrasting markings. Algeria (Blidali 
les Glacieres). Mid April. 
M. gracilis F. (Vol. 3, p. 92, pi. 22 k). — obscurior Strd. has forewings suffused with dark brown. - 
nictitaras Lenz has very prominent stigmata with bright pale surrounds. — cruda Lenz with clearly out¬ 
standing transverse lines outlining median area. - fasciata Wehrli with wide dark median shade. — Further we
