5. Athtma eufula, de Niceville. 



A. rufula, de Niceville, Butt, of India, vol. ii, p. 181, n. 474 (1886). 



Habitat : South Andaman Isles. 

 Expanse : ^, 2'6 inches. 



Description : Male. Upperside, both ivings black. Forewing M^ith 

 a prominent oval white spot at the end of the discoidal cell, and an 

 indistinct broken basal narrow white streak ; three snbapical oval white 

 spots divided by the discoidal nervules, the upper the smallest, the lower 

 rather larger, the middle spot the largest ; an oblique discal series of 

 three white spots, the upper in the first median interspace large and oval 

 touching its bounding nervules, the one below in the submedian inter- 

 space quadrate, filling the interspace, slightly constricted at each side, 

 the lowest spot below the submedian nervure elongated ; an indistinct 

 pale rufous marginal and submarginal macular band, the latter ending 

 anteriorly in a prominent bright rufous spot as in A. cama, Moore. 

 Hindwing with the first subcostal nervule and that portion of the costal 

 nervure between the bases of its branches pure white ; a broad discal 

 white band from the submedian nervure to the first subcostal nervule, 

 with a small oval spot in the costal interspace in continuation ; a 

 narrow pale marginal band, and a broader more distinct submarginal 

 band. Underside, both wings dull ochreous more or less marked with 

 black between the veins. Forewing with the bluish-white discoidal 

 streak formed of four equal portions ; a bluish- white spot near the base of 

 the submedian interspace bearing a prominent w^edge-shaped black 

 spot ; otherwise marked much as on the upperside. Hindwing with a 

 curved subcostal white streak, and a discal series of decreasing black 

 spots between the veins from the first median nervule to the costa ; the 

 abdominal margin broadly bluish ; otherwise marked much as on the 

 upperside. 



I have at last received a male of this species from Mr. R. Wimber- 

 ley ; the first female was caught as far back as 1872, and is now 

 in the Indian Museum, Calcutta. The male is nearest to that sex 

 of A. cama, but may at once be known on the upperside by the cell- 

 streak - and spot being white, not rufous ; the white snbapical spots 

 and discal band are also differently formed ; in the hindwing the discal 

 white band ending in a small well-separated oval spot in A. rufula 

 is also a distinguishing feature. The colour of the ground on the under- 

 side is a good deal different too, and the streak in the cell of the fore- 

 wing of A. rufula being divided, while it is entire in A. cavia, will 

 readily distinguish between these species.
