LEPIDOPTERA INDIO A. 
Underside with more defined ordinary markings. Forewing with a brown subapical 
streak ; two cell-marks only visible. 
Female. Upperside similar to the Wet female, except that the discocellular 
mark on fore wing is not visible, and the band on the hind wing is much narrower. 
Underside similar to male, the subapical streak on forewing being somewhat 
broader ; three marks within the cell. 
Expanse, $ 1^, ? 2 inches. 
Dry form (fig. 1, d, e). Male. Upperside. Forewing with the black outer 
band somewhat broader apically and narrower posteriorly than in the Intermedb 7 
form, its lower end smaller and inwardly-oblique. Hindwing with the band 
narrower. Underside. Forewing with ordinary marks, an incompletely-formed 
apical patch, and three cell-marks. Hindwing with similar ordinary markings. 
Female. Upperside paler yellow than in same sex of Intermediate form. 
Forewing with the outer band somewhat broader apically, its lower end smaller. 
Hindwing with a narrow marginal band. Underside* Forewing with darker ordinary 
marks, and completely-formed apical patch. Hindwvng with darker ordinary marks. 
Expanse, S 1 ? 2 inches. 
Extreme Dry form (fig. 1, f, g). Male. Upperside. Forewing with the outer 
band similar to male ordinary Dry form, its posterior end somewhat narrower. 
Ilmdiving with a slender marginal line. Underside similar to ordinary Dry form ; 
the apical patch on forewing more completely-formed. 
Female. Upperside. Forewing with the outer band somewhat narrower 
posteriorly than in ordinary Dry form. Hindwing with slender, completely-formed 
outer band. Underside. Both wungs similar to the male.

Larva and Popa. —Messrs. Davidson & Aitken write* tf£ In describing the larva 
and pupa of T. Hecabe (J. Bombay N. H. S. 1890, p. 360) we said that we had 
once, in September, got fourteen Mach pupae all on one dry twig, and so close to 
each other that they almost touched. We made no attempt at the time to sort the 
butterflies, when they emerged, from T . Hecabe. We have since discovered, however, 
that these black puprn are not to be found on the ordinary food plants of T* Hecabe , 
but on Wagatea sgoicata (N. 0. Leguminosm), and that they result from a gregarious 
larva with a black head. This leaves no doubt that they belong to a distinct 
species, and, having compared the butterflies which emerged from a large number 
of both kinds, we find that those produced from the black-headed larva and black 
pupa had a large red-coloured patch at the apex of forewing beneath, and bear 
the three dark streaks or spots in the cell in addition to the reniform spot on 
the discocellular nervules on the underside of the forewing, by which Silhetana is
