S L. dc Niceville — Butterflies of Hongkong in Southern China. [No. 1, 



while ordinal a is the wet-season form. I have ventured to put Walker's 

 two species hubneri [recte huebneri] and argns under avanta, as I do not 

 believe that either of them are found in Hongkong, and that they have 

 been wrongly identified. T. avanta is found in the "Western Himalayas, 

 in the plains of the North-Western Provinces, at Ranchi and Bholabat 

 in Maldah, botb in the plains of Bengal, in the Eastern Himalayas, 

 in the Ganjam district of Eastern India, throughout Burma, and on the 

 West River in Southern China. It has not been bred, but the larva 

 will be found on grasses. 



17. Melanitis ismene, Cramer. 



Papilio ismene, Cramer, Pap. Ex., vol. i, p. 40, pi. xxvi, figs. A, B, male, dry- 

 season form (1775) ; Melanitis determinate,, Butler, Proc. Ent. Soc. Lond., 1885, p. 

 vi, Melanitis leda, Walker, Trans. Ent. Soc. Lond., 1895, p. 449, n. 18. 



This species in seasonally dimorphic, tbe dry-season form being 

 ismene, tbe wet-season form is determinata. The larva feeds on rice, 

 Oryza sativa, Linnaeus, on large, coarse grasses, all of tbe natural order 

 Graminese. 



18.* Melanitis bela, Moore. 



Melanitis bela, Moore, Horsfield and Moore, Cat. Lep. E.I.C., vol. i, p. 223, n. 

 465 (1857); Cyllo asioa, Moore, Proc. Zool. Soc. Lond., 1865, p. 769; Melanitis aswa, 

 Walker, Trans. Ent. Soc. Lond., 1895, p. 449, n. 19. 



This species is also seasonally dimorpbic, bela being the wet-season 

 form, aswa the dry-season form. Walker records one specimen taken 

 at Kowloon late in 1891. I have not seen it from thence, but do not 

 doubt tbe correctness of the record. It occurs in Western China, and 

 as far westwards again as Kashmir. It has not been bred. 



Subfamily AMATHUSIIN^. 



19. Discophora tullia, Cramer. 



Papilio tullia, Cramer, Pap. Ex., vol. i, p. 127, pi. lxxxi, figs. A, B, female (1775) ; 

 Discophora tullia, Standinger, Ex. Schmett., p. 189, pi. \xiii, female (1887) ; Walker, 

 Trans. Ent. Soc. Lond., 1895, p. 449, n. 20 ; Moore, Lep. Ind., vol. ii, p. 197 (1895) ; 

 Fruhstorfer, Berl. Ent. Zeitsch., vol. xlv, p. 13 (1900). 



As far as is known, tbe larvse of all the species of this genus feed on 

 Bambusa sp., Natural Order Graminese, and are gregarious, very hairy, 

 and are frequently mistaken for the larvae of motbs. 



20. Clerohje eumeus, Drury. 



Banais Festivus eumeus, Drury, 111. Ex. Ins., vol. i, p. 4, pi. ii, figs. 3, male,
