1881.] Lopidoptera of the Andaman Islands. 255 



Posterior wings purple-glossed, with two subparallel raised discal 

 longitudinal lines of modified scales attached to the apparently thickened 

 bases of the first and second median veinlets, and with the cilia pale orange. 



Anterior wings below bronzy-brown with a patch of brilliant amethyst- 

 purple sparsely irrorated with white scales and extending from the end of 

 the cell nearly to the apex of each organ, and with the basal portion of 

 the wing-membrane behind the median vein and its first branch whitey- 

 brown passing to ashy posteriorly, and with a tuft of brown-tipped yellow 

 setae arranged longitudinally upon and on each side of the basal half of 

 the submedian vein. 



Posterior wings below purple-glossed, darkest over the scent-glands, 

 with an interrupted transverse discal band of white scales from near the 

 abdominal margin to the middle of the organs, where it diffuses itself 

 widely over a diffused patch of amethyst-purple. 



$. All the wings above and below paler and duller and glossed with 

 purple, the anterior ones spotted. 



Anterior wings suffused with purple on (he disk, which bears three 

 semitransparent yellow lustrous spots of the same size, relative proportions, 

 and shape as in G. attlna, Hew., with a fourth smaller and elongate yellow 

 opaque spot placed just in front of the submedian vein rather beyond the 

 middle of the organs. 



«J . 9. Eyes blood -red. 



Antennae purplish brown with the club bright luteous below. 



Length of anterior wing $ 1'25, $ 1*25 ; whence expanse = S 2'65, 

 ? 2 65 inches. 



The patch of setse 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 upper- 

 side of the posterior wings are structures peculiar to the male sex.

9 . Differs from the male only in the absence of the sexual streak in 

 the anterior wings. 



In both sexes of this species the anterior wings are tipped with paler 

 on both sides.
