1895.] L. de Niceville — Species of the genus Eurytela. 109 



Eurytelas appear to be always rare, never occurring in large num- 

 bers anywhere. Captain E. Y. Watson lias noted that their flight is 

 like that of Neptis, as they fly with wings extended flat, parallel with 

 the ground ; they settle on the tips of leaves with open wings, and then 

 raise their wings slowly over their backs. This note I can confirm, 

 having seen JE. horsfieldii alive in the forests at Selesseh in North- 

 Eastern Sumatra. The females of all the oriental species of Eurytela 

 on the wing remind one at once of tawny Neptes, or more closely of 

 species of Ergolis, which is, I believe, a protected genus, and of 

 which the very differently-coloured females of JEurytela are prob- 

 ably mimics. 



1, Eurytela castelnaui, Felder. 



E. castelnaui, Felder, Wien. Ent. Monatsch., vol. iv, p. 401, n. 26 (1860); idem, 

 id., Eeise No vara, Lap., vol. iii, p. 450, n. 739, pi. Ixi, G.gs. b, 6, male (1866); id., 

 Wallace, Trans. Ent. Soc. Lond., 1869, p. 331, n. 1 ; id., Distant, Rhop. Malay., 

 p. 136, n. i, pi. XV, fig. 10, onale (1883) ; p. 441, pi. xliii, fig. 10, female {] 886) ; id., 

 de Niceville, Butt, of Ind., vol. ii, p. 13 (1886); id., Staudinger, Ex. Schmett., 

 p. 105, pi. xxxix, male (1885). 



Habitat: Malay Peninsula (Felleo-) ; Singapore; Borneo 

 (Wallace); Perak, Malay Peninsula (Distant)-, Sumatra (Snellen); 

 Nias Island (Kheil) ; Palawan, Philippine Isles (Staudinger) ; Daunat 

 Range, Tenasserim, Burma ; Taiping and Perak, Malay Peninsula ; 

 N.-E. Sumatra; Nias Island (coll. de Niceville). 



Male specimens taken in December on the Daunat Range, Tenas- 

 serim, have on the upperside of the hindwing a prominent discal black 

 line extending from the costa to the abdominal margin. This black line 

 is also present in one specimen from Sumatra in my collection. 



2. Eurytela fruhstorferii, n. sp. 

 Haeitat : Central Java, 1500 feet. 



The male of this species may be known from the same sex of 

 Tj. castelnaui^ Felder, on the upperside of both wings in the blue colora- 

 tion being of a different shade, distinctly lighter, with a strong gloss, 

 which in some lights causes the surface to present a distinctly glossy 

 green appearance. In figuring E. castelnaui, Felder quite correctly 

 portrays the upperside " without gloss," and Dr. A. R. Wallace notes 

 the same thing. The only difference in markings noticeable is on the 

 upperside of the hindwing, E. castelnaui having the submarginal black 

 line very narrow and clearly defined, E. fruhstorferii having it many 

 times broader, and the edges somewhat diffused. 



3. Eurytela horsfieldii, Boisduval. 



E. horsfieldii, Boisduval, Faun. Ent. Madagasc, p. 54, n. 1, male fl83,S); id.,
