2O PIRDANA. 



Female. All the wings above and below paler and duller and glossed 

 with purple, the anterior ones spotted. Anterior wings suffused with 

 purple on the disc, which bears three semi-transparent yellow lustrous 

 spots of the same size, relative proportions, and shape as in C. [Unkana] 

 attina, Hewitson, with a fourth smaller and elongate yellow opaque spot 

 placed just in front of the submedian vein rather beyond the middle 

 of the organs. 



*o. 9 . Eyes blood-red. 



Antennae purplish brown with the club bright luteous below. 



Expanse, 9 , 2-65 inches. 



Hab. Andamans. 



The patch of setae on the upperside of the anterior wings, the yellow 

 tuft (which probably serves as a scent-fan) on the underside of the same 

 wings, and the lines of modified scales (which probably cover the scent- 

 glands as they seem soiled as if by some exuding fluid) on the upperside 

 of the posterior wings are structures peculiar to the male sex." (Wood- 

 Mason and de Niceville, I. c.) 



u P. lebadea, var. andamanica differs from P. lebadea, Hewitson, described 

 from Borneo, in the male being larger, the cilia of the forewing pale 

 yellow instead of white ; and in the presence on the underside of the fore- 

 wing of a prominent oblique powdery patch of violet scales extending from 

 the end of the discoidal cell to the apex of the wing." (de Niceville.) 



GENUS IX. PIRDANA. 



Pirdana, Distant, Rhop. Malay., pp. 369, 376 (1886). 



" This genus principally differs from the preceding Padnka in the 

 following characters : the upper disco-cellular nervule of the anterior wing 

 is longer than the lower ; the first and second median nervules of the same 

 wing are emitted moderately close together and remote from the lower 

 median nervule ; and there is a complete absence of the glandular patches 

 and pouches as found in Paduka. 



This genus will also contain the Hespevia ismene, Felder, a Celebesian 

 species." (Distant, I. c.)

Pivdana mdolphii, Elwes and de Niceville, J. A. S. B., 1886, p. 438, n. 

 150, pi. xx, fig. 6 "o. 



" Male. Upperside, both wings rich brown, tinted with vinaceous. Fore- 

 wing with the cilia concolorous with the rest of the wing. Hindwing with 

 the cilia orange from the anal angle to the first median nervule, broadest 

 in the middle, from the first median nervule to the apex concolorous with the 

 wing. Underside, both wings with the ground-colour as above. Forewing 

 with the inner margin broadly to the first median nervule pale ochreous, 

 the costa and upper half of the cell and all the veins except the median
