one rather variable species. It is somewhat aberrant in this group, 

 but serves to connect T. hippo and ada with T, nerissa.

^«/;. — Indian Peninsula, Philippine Islands (Coll. Wall., B. M.). 



The male is pretty constant and is well described by Boisduval. 

 The female is very variable, some specimens being nearly white, 

 with dusky costa, apex and connecting band, and the markings 

 beneath, nearly obsolete ; others are dusky brown, with patches on 

 the upper and lower wings and submarginal spots white or buffy- 

 vvhite, while beneath they are richly banded and margined with 

 chrome-yellow on a white and dusky ground. Innumerable varieties 

 connect these extremes. The Philippine specimens are smaller, 

 and the posterior band of the lower wings beneath crosses at the 

 end of the cell. The markings of the under side of the male are 

 sometimes nearly obsolete.

Female. — Above, blackish-brown ; upper wings with an oblong 

 white patch notched exteriorly, situate below the cell and the 

 second median nervule, and two small ovate white spots (the 

 upper much the largest) just beyond the end of the cell towards 

 the apex of the wings ; lower wings with a large ill-defined white 

 patch, occupying the disk of the vv'ing and reaching the anterior 

 and anal margins. Beneath, pearly white, with a broad rusty-brown 

 border, and the two subapical spots rather larger and more diffused ; 

 there is also a faint yellowish longitudinal stripe in the discoidal 

 cell of the uppers. 



Expanse of wings 2| — 2| inches.

This differs very little from T. lyncida in the male, while the 

 female is widely different.
