 termen curved, crenvdate; vein 5 of hindwing from close above vein 4. Type G. amata Brem. 



A genus without any apparent close affinity. 



C. amata Brem. ( = fuscum Btlr.) (68 a). Forewing of $ violet grey, of $ grey suffused with brown; amata. 

 markings in $ dark olive fuscous, in $ brownish; a broad outwardly bent fascia near base, limited by the 

 subbasal and inner lines; a large incompletely Y-shaped fascia beyond middle; its inner arm not reaching 

 above cell, where it forms a triangular mark; the outer very dark and broad on costa, often interrupted below 

 vein 6, angled externally above vein 3 and then deeply indented, outwardly edged by the subterminal line, 

 beyond which the termen is generally paler; a black spot in cell, and often two dark spots beyond the 

 triangular mark in cell; hindwing in <$ fuscous, hi $ blackish, with a broad orange fascia beyond 

 middle, narrowing towards and hardly reaching inner margin; a dull yellowish patch at apex and on 

 termen beyond submedian fold; Butler's fuscum appears to be merely the ordinary form of the 9, though 

 some examples of the $ occur showing the coloration of the <§ ; — ruf escens Btlr. (68 a) is a pale rosy brown rujescens. 

 form of the $, with the markings tawny olive. The species occurs in Amurland, where it was first discovered, 

 in China, Japan, Yesso, and Corea. 



C. flavomaculata Brem. (= maximowiczi Brem.) (68 a). Forewing pale violet grey, with darker clouding; ftavomacu- 

 the markings purpbsh fuscous; basal patch dark, deepest along its edges, limited by the wavy pale dark-centred lata - 

 inner line, which does not quite reach inner margin at %, and is then curved inwards to near base; an outer 

 Y-shaped fascia as in amata, but much narrower, closely preceded by a straight dark shade ; the end of the 

 shortened inner arm forms a black triangle, preceded by a large velvety black spot in cell; terminal area 

 paler, more violet grey, with blackish clouds and a black spot at apex; hindwing orange, with a large dark 

 cell spot, up to which the inner margin is fuscous; a black terminal border varying in width; the Japanese 

 form subsp. sericeum Btlr. (68 b) is darker, more purplish fuscous; — the ab. fuliginosum ah. nov. (68 b) is sericeum. 

 still deeper purple, the hbidwing wholly dark, except a short median orange band. Found in the Ussuri/ M %"'* S " OT - 

 district, Amurland, Dauria, and Japan. 



27. Genus: Aj*cte Roll. 



Tongue well-developed; frons smooth; palpi with closely appressed scales, upcurved in front of face, 

 the third segment short; antennae of $ simple; tibiae fringed with long hair, without spines; thorax and ab- 

 domen clothed with long hairy scales; the penultimate segment of dorsum of $ bearing a roughly ridged 

 brown horny plate at middle. A genus of large, stoutly built, moths with elongate forewings, occurring chiefly 

 in India and the Malay islands, one species only being found in Kashmir. The genus is closely related to Gocy-
