300 MACROGHTHON1A; MICROXESTIS; ARCYOPHORA; ACONTIA. By W. Warren. 



area beyond diffusely filled with dull greenish brown; a sinuous band of the same colour beyond outer line, 

 running into apex; the veins and folds dotted with dark; the eosta marked with larger and irregular spots; 

 subbasal and inner dark lines both bent in submedian fold, the latter thicker and more evident; outer line fine 

 and blackish, irregularly crenulate; the brown band beyond it succeeded by a narrower band of the pale 

 ground colour, outwardly limited by an irregular row of black lunules, those below vein 3 merely outlined 

 in black; termen somewhat tinged with brown, especially at anal angle; terminal line fine, blackish; fringe 

 pale grey; a black, slightly crescentic, streak on discocellular, edged with pale scales; hindwing didl whitish, 

 terminally greyish, especially towards apex. Nearest to K. multipunctata Moore from N. India, the ground 

 colour rather paler. Occurs in Japan and W. China; also in Mongolia andAmurland, whence Oberthur's type 

 of macroptera. 



(rrisea. K. grisea Hmps. (521, m). Forewing olive green; the costal half of wing and the area beyond outer line 



purplish; inner line dark, thick, oblique to submedian fold, then bent inwards; an oblique blackish streak below 

 vein 2 at base; outer line blackish, oblique and waved to submedian fold, bent outwards above inner margin; 

 subterminal line oblique, black, dentate, defining the outer edge of the purplish shade; terminal black spots, 

 the tufts of scales at middle and end of cell white; hindwing with the patch of androconia in <$ rufous and 

 more prominent; in $ grey, darker along termen. Yatong, Tibet; also from the Naga Hills, Assam.

 antennae of <$ bipectinate, of $ ciliated; thorax with triangular ridgelike crest; forewing with costa curved, 

 apex bluntly falcate; veins 7, 8 stalked; 9, 10 stalked, 9 anastomosing with 8 to form the areole; the retina- 

 culum a tuft of hair below median vein; wings smoothly scaled, the forewing with irregularly oblique markings. 

 Type M. fervens Btlr., the sole species of the genus. 



fervens. M. f ervens Btlr. (= falcata Graes., pyrausta Graes.) (521). Forewing brown or grey brown, paler, more 



ochreous, in the <$; lines dark; subbasal line obliquely curved inwards to base of inner margin; inner line 

 oblique, not reaching below median vein; median shade oblique, diffuse; outer line curved, concave outwards,

 apex to anal angle, marked by spots, followed by on olive shade below vein 6; some dark spots along 

 termen ; fringe concolorous ; hindwing fuscous grey in $, sometimes with a tinge of reddish ; pale luteous or greyish 

 white in (J. Japan and Central China; Graeser's types from Amurland. 



18. Genus: Microxestis Hmps.

 the third smooth and short; antennae of <$ shortly ciliated; thorax and abdomen smoothly scaled, without 

 crests; forewing with costa and termen evenly curved, the inner margin lobed at middle and bearing a tooth 

 of scales; vein 7 from upper angle of cell, 6 from below it; 7, 8, 9 stalked; no areole; hindwing with costal 

 anastomosing with subcostal to middle of cell; veins 3, 4 stalked. Type M. wutzdorffi Pilng. 



wutzdorffi. M. wutzdorffi Pilng. Forewing rufous ochreous ; the markings all obscure ; inner line shown by a faint 



pale oblique mark; outer line rufous, slender, bent outwards below costa, inangled beyond cell, and incurved 

 below vein 4 ; an angled rufous median shade ; a black dot at end of cell ; a small whitish subapical spot with 

 a black dot on its outer edge; hindwing white, the termen slightly rufous. Known only from Palestine; a small 

 species. 



19. Genus : Arcyophora Guen. 



Tongue present; frons smooth; palpi upcurved, smooth and slender, the third segment short; antennae 

 of c? typically subserrate, with fascicles of cilia; thorax and abdomen smoothly scaled, without crests; tibiae 

 simple; forewing with costa straight, apex prominent, termen well curved; the inner margin lobed, and with 

 tuft of hair scales near base and at outer angle. Type A. longivalvis Guen. from Africa. One species only from 

 the Palaearctic region. 



denlula. A. den tula Led. (= innubila Swinh.). Forewing pale ochreous, faintly grey tinged; the lines pale, con- 



versely grey edged; the inner line curved, not straight; subterminal faint, macular; hindwing dull white, greyer 

 angulifera. towards termen; angulifera Moore is a somewhat greyer form, but not confined to the <$<$. The type of anguli- 

 fera from the N. W. Himalayas, of innubila from Mhow; Lederer's denlula from Persia and Syria.
