472 L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. [No. 3, 
on MounPKaba, 5,200 feet, in South Sumatra. He saw seven or eight 
specimens, but caught only one male, which Dr. Martin has seen. 
437. Ilerda ila, de Niceville, n. sp. 
Hagen as epieles , Godardt [sic]. 
Habitat : Battak mountains, N.-E. Sumatra. 
Expanse : cf, 1*4 to 1*5; 2 , 1*5 to 1'6 inches. 
Description: Male. Upperside, forewing differs from typical 
L epieles , Godart, from Java, in the iridescent deep purple colour being 
of greater extent, approaching much nearer the costa and the outer 
margin; never with a diffused yellow patch beyond the end of the dis- 
coidal cell. Hindwing with the purple coloration of greater extent 
also, the orange lunules on the margin greatly reduced in size and 
fewer, confined more to the anal angle. Underside, both wings as in 
I. epieles. Female. Upperside, forewing differs from typical I. epieles 
in having the orange area much larger, almost reaching the base of the 
wing. Hindwing differs in having a very large continuous orange 
area occupying the outer half of the wing, instead of a series of con¬ 
joined broad marginal lunules, with sometimes a small indistinct 
diffused orange patch on the disc. Underside, loth ivings as in the 
male. 
It is possible that “ Tliecla ” phoenicoparyphus, Holland, described 
from Hainan Island, (the type being said to be a male but probably 
actually a female) is the name which will have to be applied to the 
Western Chinese and Indian form of J. epieles, as from the figure and 
description of the type of that species, the orange areas on the upper- 
side of both wings appear to be of about the same extent; the fore¬ 
wing, however, has the orange area (though it is variable in extent) 
always less than half as large as it is in true J. epieles. I. ila differs 
from both in the female by the orange area on the upperside of the 
hindwing occupying fully half the surface instead of being confined to 
a marginal band. 
J. ila is not very common on the Central Plateau, but occurs 
throughout the year, as there are specimens in Dr. Martin’s collection 
taken in every month. I have described it from a long series of 
both sexes. 
438. Dacalana vidura, Horsfield. 
Grose Smith. Hagen. Distant. Occurs in the plains and on the 
outer hills. Is common at Selesseh in April. The collectors brought 
in perhaps five or six males to one female.
