1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 483 
taken in May, June, July and October. The males vary greatly in 
size, the smallest measures ‘95 of an inch, the largest 1*35 inches. 
The markings aud coloration of the underside remind one of those of 
Lampides , which is considered to be a protected genus, and may perhaps 
to some extent account for the scarceness of specimens of R. deliochus 
in collections, as they are passed over for the common species of 
Lampides which they may mimick. 
500. Rapala rhgecus, de Niceville. 
B. rhoecus, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. ix, p. 319, n. 35, pi. P, 
fig. 47, male (1895) ; idem, id., l.c., vol. x, p. , n. 27, pi. T, fig. 40, female (1896). 
Taken at Bekantschan and in the Battak mountains, where this 
fine species is fairly common in May and July, rarer in March, April 
and October. The female on the upperside is somewhat marked with 
red on both wings, on the inner margin of the forewing, and near the 
anal angle of the hindwing, an unusual feature in this genus. 
501. Rapala schistacea, Moore. 
A few specimens only from Selesseh taken in May and June. 
502. Rapala scintilla, de Niceville. 
Hitherto known from Sikhim only. Its occurrence so far south 
is very interesting. It is quite a distinct species, which can always 
be discriminated in both sexes by the peculiar coloration of the under¬ 
side alone, though as regards the male the restriction of the blue 
gloss to the upperside of the hindwing best distinguishes that sex. 
In Sumatra it is commoner than R. schistacea , Moore, and is found 
from Selesseh to Bekantschan from March to June. 
503. Rapala orseis, Hewitson. 
Hewitson. Grose Smith. Kirby. Distant. Originally described 
from Sumatra, certainly the commonest species of the genus, and 
found from Bindjei to Soengei Batoe throughout the year. 
504. *Rapala chozeba, Hewitson. 
Hewitson. Grose Smith as var. chozeba. Hagen as Beudoryx [sic] 
chozeba. Kirby. Originally described from Sumatra. We have failed 
to recognise it. It is very near to R. orseis , Hewitson. 
505. Rapala nissa, Kollar. 
Only two females taken in the Battak mountains in October, 1893.
