LEPIDOPTEBA INDIGA. 
Female. Upperside. Forewing with the basal portion irrorated with dark greyish- 
brown scales, the white patch very large, occupying more than two-thirds of 
the wing, its outer margin very irregular, the patch sometimes intersected by the 
veins; basal half of costal band broadly greyish-brown, the remainder black, 
extending round the apex and outer margin, and running in on the hinder margin, 
where in the middle it joins the grey irrorations, this outer band at the apex is very broad 
and is black throughout. Hindwing greyish-brown, sometimes very pale, costal margin 
very broadly blackish, a white patch in the middle of the wing which is sometimes 
more or less suffused with grey and varies much in size. Underside, much as in the 
male. Forewing with the white patch as large as it is above. Hindwing v T ith the 
discal sinuous brown line more pronounced, a short brown shade through it from the 
abdominal margin, and both wings with lunular sub-terminal brown marks. Antennae, 
head, thorax and abdomen brown, paler beneath, palpi and thorax beneath white.

Imago.— Male. Forewing, upperside, dark brownish-black at the base, a white 
transverse band, which commences with a sub-costal streak near the base, and descends 
outwardly before the middle of the wing, is crossed by a broad bar from the basal 
brown space which becomes nearly pure black ; then the white band expands inwards 
on to the hinder margin very broadly, its inner and outward edges being very 
irregularly sinuous ; all the broad black marginal band being pure black, being very 
broad at the apex and gradually narrowing to the hinder angle. Hindwing of a 
uniform very dark brownish-black colour, without markings. Underside. Forewing 
chocolate-brown, the white band much reduced, macular, and almost continuous, with 
blackish suffusion inside it, on the centre of the wing and some similar suffusion 
outside the band, above its middle ; the outer portion of the wing with pale streaks. 
Hindwing of a uniform rather pale chocolate-brown, some obscure mottlings of a darker 
brown, and a brown, obscure band from the abdominal margin beyond the middle, 
which becomes more or less obsolete inwards. 
Female, like the male. The white band slightly narrower hindwards.
