534 L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. [No. 3, 
Mabille ( —subfasciatus, Moore, and ulunda , Plotz), occurs in South 
India, Burma, the Malay Peninsula, Java, Borneo, the Sulu Isles, 
and the Philippine Isles. In Sumatra it is common on the outer 
hills and plentiful near Namoe Oekor throughout the year. 
645. Koruthaialos xanites, Butler. 
Grose Smith. I sent a long suite of specimens of this genus allied 
to K. xanites to Captain Watson, who pronounces that amongst them 
are several undescribed species from Sumatra, to be discriminated by 
the length of the palpi and the greater or less prominence of the 
orange markings on both sides of the forewing. As this latter feature is 
apparently extremely variable I hesitate to describe any of these 
supposed new species, as before doing so I think that critical examina¬ 
tion of the prehensores of the males of all the species of the genus 
should be made. 
646. Koruthaialos verones, Hewitson. 
Astictopterus verones , Hewitson, Ann. and Mag. of Nat. Hist., fifth series, vol. i,

Hewitson. Grose Smith. Originally described from Sumatra 
thus :—“ Both sides rufous-brown. Underside of the anterior wing 
marked by a subapical rufous spot.” This is one of the well-marked 
forms of the genus, which I possess also from Java. It occurs in 
Sumatra not uncommonly with K. xanites , Butler. 
647. Koruthaialos kerala, de Niceville. 
K. Icerala, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. x, p. , n. 33, pi. T, 
fig. 48, male (1896). 
Somewhat rare, occurs in the mountains in May. 
648. Koruthaialos kophene, de Niceville. 
K. kophene, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. x, p. , n. 34, pi. T, 
figs. 49, male-, 50, female (1896). 
A rarer species than the one last-named, we possess three or four 
specimens only from Sumatra. All the species of the genus are inhabi¬ 
tants of the forest, where they are chiefly found on grassy forest paths 
and on low flowers. They occur more abundantly at higher elevations 
south of Namoe Oekor. 
649. Suada swerga, de Niceville. 
8. swerga, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. ix, p. 372, n. 1 (1895). 
This species has a wide range, occurring in Sikhim, Burma, the
