Underside grey-white. Both wings crossed beyond the middle by a linear band of white 

 bordered outwardly with brown, both with a submarginal brown line scarcely seen on the 

 anterior wing : anal angle of posterior wing with two brick-red spots, one touching the lobe 

 which is black, the other marked with a black spot.

 the apical half dark brown. Posterior wing with the costal margin broadly rufous-brown, 

 polished where the wings meet, and green in a bright light : the outer margin dark brown, 

 narrow : aual angle with two tads (one very short) and a red spot on the lobe. 



Underside. Grey-white, rufous at the base of both wings. Both wings crossed beyond 

 the middle by an undulated linear band of white bordered inwardly with brown : both with a 

 submarginal brown line scarcely seen on the anterior wing. Posterior wing with the shoulder

This species is very nearly allied to the last two but differs from both in the brown base of 

 the underside. Like T. Elika it is without the discoidal spot and differs from it in the 

 greater extent of brown on the upperside of the anterior wing, and in the position of the band 

 of the posterior wing which is lower down at the costal margin.
