10 LEPIDOPTERA INDICA. 



lilack, aud from the sub-median iiervure to the abdominal margin with greyish-black, 

 with a fine black anteciliaiy line, and immediately internal to this a very faint and 

 fine silvery-grey line decreasing from the anal angle and dwindling to nothing before 

 reaching the apical angle, with the cilia dark brown, evenly tipped with silvery- 

 white, aud with the tails black-brown, the unequal sub-median and second median 

 .shorter ones edged internally with silvery-white cilia, and the longer intermediate 

 first median one white-tufted at its inner extremity. Underside, both wings much 

 lighter. Forewing with a broad and prominent white band bordered both sides 

 with fuscous of a darker shade than the rest of the ground colour, passing oflF from 

 the greyish-white basal portion of the inner margin across the organ to within a 

 short distance of the costa, increasing in its course to a little beyond the first 

 median nervule, and thence decreasing to its anterior extremity (which is washed 

 with fuscous), so that its outline, while almost straight internally, is bluntly obtuse- 

 angled externally, and with the outer margin at the inner angle obsoletely trilineated 

 with white as in the hindwing. Hindioing with a narrower and less conspicuous discal 

 whitish band of uniform width throughout, not sharply defined, but on the contrary 

 dift'used externally, and bordered internally with a line of fuscous which is darker 

 than the ground, sharply bent inwards at right angles to itself to the abdominal 

 margin and externally margined with brassy at the posterior end, with the deep 

 black spot of the small anal lobe, a large grey patch of grey scales between the ends 

 of the sub-median nervure and the first median nervule, an intense black spot next 

 to and about half the size of this between the ends of the first and second median 

 uervules, and a very short and transversely elongated or narrow similar but incon- 

 spicuous black spot between the ends of the first aud second median nervules, all 

 internally margined with a discontinuous line of brassy scales which extends from the 

 point where the dark discal striga with its brassy edging reaches the abdominal margin 

 all alono' the outer maroin of the oro;ans, followino- the inner contours of the above 

 described spots, up to the second sub-costal nervule, and with the external margin 

 finely lineated wdth three regularly concentric silvery-white lines separated from one 

 another by the black anteciliary line and the brown bases of the cilia. (Wood-Mason 

 and de Niceville.) 



Female unknown. 



Expanse of wings, $ 1 to I-j-q inches. 



Habitat. — Andamans. 



We have not seen this species ; it is said to have no secondary sexual character ; 

 Ave give copies of de Niceville's figure ; it appears to be only separable from 11. rana, 

 de Niceville, in having no sex mark.
