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 has 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 E. 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 Eurytela are prob¬ 
ably mimics. 
1. Eurytela castelnaui, Felder. 
E. castelnaui, Felder, Wien. Ent. Monatsch., vol. iv, p. 401, n. 26 (1860); idem, 
id., Reise Novara, Lep., vol. iii, p. 450, n. 739, pi. lxi, figs. 5, 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, male (1883) ; p. 441, pi. xliii, fig. 10, female (1886); id., 
de Niceville, Butt, of Ind., vol. ii, p. 13 (1886); id., Staudinger, Ex. Sehmett., 
p. 105, pi. xxxix, male (1885). 
Habitat: Malay Peninsula (Felder)) 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. 
Habitat : Central Java, 1500 feet. 
The male of this species may be known from the same sex of 
E. 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 hind wing, 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 (1833); id., 
de Niceville (part), Butt, of Ind., vol. ii, p. 12, n. 302 (1886); E. horsfieldi, Wallace,
