vein 6, angled inwards on discal fold and outwards at vein 4, then strongly incurved, defined by yellow on inner 

 side, and followed bj a similar red line ; subterminal line yellow defined by red, minutely dentate, angled inwards 

 on the two folds; veins of terminal area red; bindwing with base and costal area white, the rest of wing yellow; 

 terminal area rufous below vehi 6; fringe rufous except at apex; in the $ the oblique dark band from middle 

 of costa is absent ; the lines in costal half are separate and dentate, the outer line sinuous below vein 4, and 

 the line beyond it defined by yellow on the dark area. Japan; also occurs in N. India. 



Sect. II. No ridge of metallic scales between antennae. 



S. sanguinolenta Moore (53 g, h). Forewing with basal half and costal area to apex bright yellow, the sanguino- 

 rest of whig greyish irrorated with black, more strongly in the <J; a crimson point at base of cell, and some lmta - 

 crimson and white scales at base of inner margin; a crimson ring on costa before middle and double waved 

 line, filled in with blackish, from it to inner margin; a waved crimson median line from below costa to median 

 vein, with points before and beyond it below costa and two conjoined rings on inner marginal area; the 

 dark terminal area with waved edges defined by crimson; the lines indicated on costal area by crimson points; 

 two small yellow dots beyond cell followed by a waved crimson and black line between veins 6 and 3; subter- 

 minal line dentate, crimson edged inwardly with blackish, with some yellow dots on it above middle; hindwing 

 with basal half and the costa white; terminal half brown grey; fringe purplish pink. Recorded from Omei-shan 

 West China; originally described from N. India. 



4. Genus: Ckionoiiiera Btlr. 



Tongue well developed; frons smooth; palpi obliquely upturned, closely scaled, the third segment 

 half as long as second; antennae of $ ciliated; thorax and abdomen smooth; forewing with prominent apex, 

 the termen oblique, curved and even; veins 8, 9, 10 stalked; in the hindwing veins 3, 4 and 6, 7 are stalked; 

 the costal anastomoses with the subcostal at base only; the retinaculum of <§ bar-shaped, from subcostal vein. 

 Type C. superba Moore. 



C. argentea Btlr. (53d). Forewing silvery white; the markings orange; a subbasal spot on costa; an argentea. 

 inner band, expanding at costa, outwardly black edged; an outer slightly curved band from costa to tornus, 

 swollen at costa into a large triangular blotch with white centre, inwardly black edged; a terminal band from 

 apex to submedian fold, inwardly black edged; fringe yellowish except towards tornus; hindwing silvery white; 

 in the ab. obliterata ab. nov. (== ab. 1 Hmps.) the markings of forewing are all but obliterated. Japan. oblUerata. 



C. chinensis Swinh. (53 d). Forewing pure white; the costal edge blackish; the markings orange; a chinensis. 

 spot at base of costa joined by a band to an inner band with sinuous edges slightly black edged; the apical 

 area from costa beyond middle to inner margin before tornus, its sinuous inner edge defined by black; a white 

 spot on it just below costa, and a lunulate spot before termen from below vein 3 to submedian fold, both in- 

 wardly black edged; an oblique quadrate white patch with uneven edges from below costa at apex to above 

 vein 4, black edged except towards apex; fringe orange at base, blackish at tips; hindwing pure white. West 

 China. 



5. Genus: Tyana Walk. 



Tongue present; frons smooth; palpi obliquely upturned, slender and smooth, the third segment long; 

 antennae of <J almost simple, with enlarged basal segment; thorax and abdomen smoothly scaled, without 

 crests; forewing ample, the costa strongly arched, the apex prominent; vein 6 from below upper angle; 7, 8, 9, 10 

 stalked from the angle; hi hindwing veins 4 and 5 are coincident, sometimes shortly stalked with 3; costal and 

 subcostal anastomosing to middle of cell; retinaculum of <$ a tuft of hair from below median vein. Type T. calli- 

 chlora Walk. 



Sect. I. Hindwing of $ with large fold on inner margin, holding a mass of flocculent 

 hair. 



T. falcata Walk. (= pustulifera Leech nee Walk., acypera Hmps. <J only) (53h). Forewing yellow green falcafa. 

 the costal edge brown and white ; brown dots at angles of cell, sometimes also one at origin of vein 2, and another 

 below it on submedian fold; the termen and fringe yellow; hindwing white; — in ab. literata Wilem., from literata. 

 Formosa, the discocellular of forewing bears a sinuous brown bar. Described from Sikkim and occurring in 

 Formosa; the $ type of acypera Hmps. was from Omei-shan, West China. 



T. monosticta Hmps. (= acypera Hmps. $ nee <?) (53k). Forewing yellow green; costal edge white, nwnostwta. 

 with yellow below it towards base ; the inner margin yellow ; a reddish discoidal spot, usually with white centre ; 

 fringe white with the apex pink; hindwing pure white. Described from 2 £$ from Pu-tsu-fong, West China. 



In these two species the apes of forewing is acutely produced and the termen nearly straight.
