margin before the middle : crossed near the outer margin by some white spots, more distinct 

 as they approach the anal angle, commencing, like the other band, by a minute white spot 

 on the costal margin : the anal angle irrorated with black and white : the lobe black.

Very near T. Atena, from which it differs in the straighter costal margin of the anterior 

 wing, in the different colour, in the straight band on the underside of the anterior wing, and in 

 the band of the posterior wing, which approaches much nearer to the subbasal white spot.

Upperside. Female. — Cerulean-blue, the nervures black. Anterior wing with the costal 

 margin and outer margin (where it is very broad) dark brown. Posterior wing with two tails :

Underside rufous-brown. Both wings with a linear white spot at the end of the cell, 

 both crossed by a linear band beyond the middle and by two submarginal bands of white. 

 Posterior wing with a luuular spot near the base : crossed by a band of pale blue spots at the 

 middle and beyond the middle by a broad rufous band bordered with white : the lobe and

Underside pale brown. Auterior wing (where it meets the posterior wing) black irro- 

 rated with blue and grey : crossed beyond the middle by a linear band of pale blue. Posterior

This species resembles T. platyptera of Felder, and shows the near relation which Trichonis 

 Theanus bears to Thecla.
