like that in arcuata, but not so acute; its lower arm with only a slight protuberance between veins 3 and 4; 



the median pale band more or less Riled up with grey brown; the terminal area pearl grey; hindwing as in 

 algira; the oV 1 are apparently rather darker than the ??. China and Japan. 



0. algira /.. (= achatina Sulz., triangularis Hbn) (61b). Forewing brownish fuscous, with a purplish algira. 

 tinge when fresh; a whitish median band narrowed in middle, edged inwardly by Ihe creel but slightly oulcurved 

 inner line, outwardly by the similarly incurved median line: outer line acutely angled outwards on vein (! 

 and bluntly bent between veins 3 and 4. then sinuous to inner margin near median line; a black apical 

 streak of two spots; the terminal area violet grey: hindwing fuscous, with a diffuse whitish median band: the 

 terminal area grey at middle: fringe grey, below apex whitish; the ab. mandschuriana Star is more '"/"" / - s ' t- '"<- 



uniformly purplish or slaty grey, with the median band only slightly paler, not white. Larva yellowish grey, 

 darker on dorsum, with tine black longitudinal lines; venter and feet pale grey; spiracles black; head yellowish 

 grey; feeding on Rubus. A European species, but occurring only in the South: Switzerland, the Tyrol, Austria, 

 the Crimea: in Algeria and the Canaries; in Asia Minor. Syria, Ferghana; Amurland, Corea, China, and Japan. 



0. arcuata Moore ( = joviana Gtten. nee ('ram., gueneei Snell) (61b). Distinguished by the inner line arcuata. 

 uf forewing- being sinuous: the median line limiting the pale median band very strongly concave, meeting Ihe 

 extremities of outer line on costa and inner margin; the outer edge of the oblique black apical streak excised. 

 Leech records a single example of this common Indian species from Gensan, Corea. 



0. albivitta Moore (61b). Always larger than algira, with the median band always whiter and generally albivittu. 

 much broader; the inner line more evenly aud gradually curved; the dark area between median and outer 

 lines broader: hindwing with the white median band more prominent. Described originally from India; occurs 

 also in Arabia, in Syria, and in Egypt; examples from these last localities, Haifa and Biskra, have the median 

 pale band much broader. 



0. analis Gaeit. (61b). Forewing olive fuscous, deepest in postmedian space between middle and outer analit. 

 lines: inner line straight, outwardly oblique, followed by a line white line: median line less oblique, approaching 

 inner line on inner margin, preceded by a broad white space; area between the lines dusted with iron grey; 

 outer line obliquely concave outwards to below 6, then wavy, parallel to termen, to below 4, then incurved 

 to touch median line on inner margin, its costal curve edged by a pure white curve with diffuse outer edge; 

 subterminal line hardly visible: termen greyer: fringe white; costo-apical area deep fuscous, its oblique outer 

 edge roughly angled; hindwing olive fuscous, paler basewards; a bluish white straight median band; a fine 

 bluish white streak from anal angle to vein 2 where it is followed by a small black, inwardly white-spotted, 

 blotch: extreme termen bluish grey; fringe white, except at apex. Recorded from China; the insect occurs 

 throughout India, in Burma, Ceylon, and Java. 



0. arctotaenia Guen. (61c). Larger than analis, more brownish; instead of the grey tinged median krclotaenia. 

 band with converging sides an evenly wide white band, with only slight dusting at each end; outer line 

 below vein 6 sinuous, not wavy; two black subapical blotches, externally pale edged, with a sinus between 

 them: the pure white edging of outer line at costa concisely bounded externally: termen and fringe greyish 

 white: hindwing with median band whiter; a dark subterminal cloud above anal angle; no black spot on 

 vein 2: terminal line finely dark; termen and fringe whitish. An Indian species, extending into China and Japan. 



0. stuposa F. (= festinata Walk) (61c). Forewing deep olive brown in basal area and between middle sluposa. 

 and outer lines: the intermediate space- whitish dusted with pale olive brown, thickest at costa and inner 

 margin: terminal area suffused with brownish and peppered with bluish grey: inner line uniformly outcurved 

 in middle and incurved at each margin, rarely outbent in middle and not incurved below, edged by a white 

 line; median line irregularly sinuous; outer line angled on vein 6, then incurved, with a slight outward pro- 

 jection between veins 3 and 4, edged by a white line: subterminal line acutely dentate, limiting a darker 

 shade, and ending at apex in two black white edged blotches: teeth of the line often produced as pale streaks 

 along veins to termen: a small black cellspot; hindwing blackish fuscous, traversed by a straight diffuse whitish 

 band; the termen greyish or whitish towards anal angle; fringe white in apical half, fuscous below: Lhe form 

 occurring- in China — subsp. tumefacta subsp. nov. - - has the small projection between veins 3 and 4 in tumefacta. 

 the outer line swollen into a more or less prominent rounded protuberance: the Japanese specimens agree 

 with the typical Indian form. 



0. praetermissa spec, nor, (61 c ?; 63c cf). Hitherto confused with the following species crameri Moore, which '^J/ ' 

 it much resembles, but from which it differs as follows; the broad white band of forewing contains a small 

 black cell dot, never present in crameri; lhe dark area beyond it is not so wide, the costal arm of outer 

 line is curved not straight, more finely and often interruptedly marked with white, Lhe lower arm below the
