MOXI.MA. Bv W. Wahren. 



pallida, ab. pallida Tutt (22b) has a pale whitish ochreous ground colour; — in rufescens Tutt (22b) the reddish 



rufescens. cr rev tint is predominant: - in rufa Tutt the ground colour is red; — and in brunnea Tutt the rufous 



f a ' tints give place to purplish brown ; - - ab. hirsuta nor. (22 b) , apparently a dark powdered form of ab. 



hirsuta i»-'M'"l" • > s g re . v w 'th a faint rufous tinge, plainest, as usual, at base of vein 2, thickly dusted with dark 

 grey; the lines black, the inner preceded, the outer and subterminal followed, by a thick fuscous blackish 

 shade; the black mark on submedian fold before outer line slight, and the black of the cell reduced to 

 two narrow spots, one horizontal, pointed outwardly, touching inner line, the other narrow, oblong, and 

 vertical, before reniform: hindwing pale luteous grey with broad fuscous terminal border, the whole dusted 

 with darker; the cellspot well-marked; the fringe pale rufous. 1 o" 1 from Silvaplana, the Engadine, Switzer- 

 land, received with several of the pallida form and others of typical coloration. Like the examples of 

 pallida, the underside of this specimen has the cellspots and outer lines strikingly black and thick. Generally 

 distributed in Europe and through • Central Asia to Amurland and Japan. — Larva green dotted all over 

 with yellow; dorsal and subdorsal lines yellowish white; spiracular line broad, white, with dark upper edge; 

 head pale green : on various shrubs and trees. 



castanei- M. castaneipennis I lamps. (20 g). Forewing deep rufous striated with fuscous; the cell darker; 



pennis. orbicular and reniform stigmata mixed with fuscous, their edges pale; postmedian and submarginal lines 

 nearer than usual, the interval striated with fuscous; hindwing reddish grey. Described from a single cf 

 from Narkundah, Kashmir. 



ferrosticta. M. ferrosticta Hamps. (20 g). Forewing pale lilac grey, faintly flushed with brown; the lines in- 



distinct, the outer lunulate-dentate, the teeth marked dark on the veins; a diffuse brownish median shade 

 bent in middle; orbicular and reniform stigmata with obscure yellowish edges and defined below by curved 

 reddish brown marks; marginal area brown, the submarginal line marked by dark teeth on the veins; 

 hindwing brownish grey; the fringe white. Described, like the preceding species, from a single cf from 

 Narkundah, Kashmir; it appears to much resemble M. rorida ab. sieversi Christ, from Tiflis, Armenia. 



munda. M. niunda Esp. (= gemina BkTi., geminatus Haw., bimaculatus Haw., lota Dup.) (22c). Forewing 



brownish grey, not much dusted; the lines generally obscure, the outer line marked by dark vein-dashes; 



the submarginal pale with black spots before it, two, the usual number, beyond cell, the others more rarely 



expressed ; orbicular and reniform large, with pale outlines, the latter often blackish in lower lobe ; one, or 



the other, or both may be obsolete; the median shade is equally variable; hindwing dull brownish grey; — 



immaculata. the ab. immaculata Stgr. (22 c) shows the submarginal line without any black spots. The ground colour 



pallida, also varies as much as the markings: thus ab. pallida Tutt (22c) has the ground whitish, and ab. grisea 



grisea. f u fi (22 c) has it grey, without brown or rufous admixture ; — ab. rufa Tutt (22 c) is uniform rufous with 



, r y°" the markings slight: — in striata Tutt there is a black streak from near base alone subcostal vein and 

 striata . 



another along median to the lower lobe of reniform stigma. Widely distributed in Europe, Britain, France, 



Germany, Switzerland, Hungary and Russia; Amurland and Japan. The Japanese specimens are, as usual, 



larger than European, and all of a dull brown grey, with few markings, one ? of the immaculata form being 



all but unicolorous; but the black spots of the submarginal line are, as a rule, well-developed. — Larva 



pale ochreous, much mottled with dark; the tubercles white; dorsal line pale, brown-edged; spiracular line 



pale, edged above with blackish, and partially with white; segment 12 with a transverse pale line and two 



brown spots before it. On various trees and shrubs. 



lizetta. M. lizetta Btlr. (22 d). Forewing dull greyish brown, like the tint of the Japanese miniosa, rarely 



rufous-tinged, often sprinkled with dark scales; inner and outer lines marked only by blackish vein-dots; 

 submarginal pale, preceded by patches of rufous scales in the folds and at costa, and followed by a rather 

 prominent blackish shade beyond cell; stigmata obscure, with faint pale outlines; orbicular often obsolete; 

 pallescens. reniform with lower lobe always dark fuscous; hindwing dingy fuscous, paler in o 71 ; — in ab. pallescens 

 hoc. (22 d) the ground colour is pale ochreous stone colour, the thorax and abdomen the same, the only 

 dark markings being the lower lobe of reniform, the shadings of the submarginal line, and the series of 

 marginal black spots; the hindwing the same colour or slightly darker. From Yokohama, Japan, and 

 Kiu-shiu Island. 



populi. M. populi Strom. (= populeti F., subplumbeus Haw., ocularis Frr., tremuleti Teteiis) (22 d). Fore- 



wing dull brownish grey in <?, darker, purplish fuscous, in ?; the lines indistinct, but plainer in the darker ??; 

 stigmata large, of the ground colour or darker, always with pale rings; submarginal line pale accompanied 

 by rufous or dark spots between the veins; median shade generally visible; hindwing greyish fuscous; — 

 obsoleta. ab. obsoleta Tutt represents the palest and least-marked form of all; — in intermedia Stcph. the darker 

 intermedia, purple tints prevail, the majority being probably ¥?; — nigra Tutt is a rare perfectly black form; — in 

 "'£'"■ donasa Esp. the stigmata and the surrounding area are described as rufous. A somewhat rarer and local 

 species, occurring in Britain, France, Germany, Switzerland, Scandinavia, Livonia, and the Urals. — Larva pale 

 green; the lines whitish; head greenish, marked with black; feeds on poplars only.
