472 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 



on Mount Kaba, 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 epicles, Godardt [sic]. 



Habitat: Battak mountains, N.-E. Sumatra. 



Expanse : 6", 1*4 to 1*5 ; 2 , 1*5 to 16 inches. 



Description : Male. Uppb;rside, foreioing differs from typical 

 I. epicles, 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. Hiudiving 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. epicles. Female. Upperside, foreioing differs from typical I. epicles 

 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, both wings as in the 

 male. 



It is possible that " Thecla " 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 I. epicles, 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 I. epicles. 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. 



I. 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 loug series of 

 both sexes. 



43S. Dacalana vidura, Horsfield. 



Grose Smith. Hagen. Distant. Occurs in the plains and on the 

 outer bills. Is common at Selesseh in April. The collectors brought 

 in perhaps five or six males to one female.
