Female. Upperside similar to the Wet female, except that the discocellular 

 mark on foreiving is not visible, and the band on the hindwing is much narrower.

Laeva and Pupa. — Messrs. Davidson & Aitken write, " In describing the larva 

 and pupa of T. Eecahe (J. Bombay N. H. S. 1890, p. 360) we said that we had 

 once, in September, got fourteen black pupas all on one dry twig, and so close to 

 each other that tbey 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 pupse are not to be found on the ordinary food plants of T. Hecabe, 

 but on Wagatea spicata (N. 0. Leguminosas), 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 forewiug 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
