dark brown : the outer margins dark brown. Anterior wing with the costal margin brown : 

 the discal spot small, round, rufous. Posterior wing with one tail. 



Underside rufous and grey. Both wings crossed beyond the middle by a linear band of 

 small indistinct white spots bordered with brown. Posterior wing with a small indistinct 

 spot of white and brown near the middle of the costal margin, and some submarginal brown 

 spots near the anal angle which has the lobe black crowned with scarlet, and a scarlet spot 

 marked at its base with black. 



Exp. 1| inch.

Upperside. Male. — Brilliant glossy blue. Anterior wing with the costal margin and 

 apical half dark brown : the discal spot small, round, rufous. Posterior wing with one tail : 

 the costal and outer margin brown, rather broad. 



Underside rufous, spotless, except near the anal angle of the posterior wing, where it is 

 crossed by two short bands of white spots bordered with brown : the lobe, the space between 

 it and the tail black. 



Exp. 1^ inch.

Probably only a variety of T. punctum, with a very slight trace of the transverse bands of 

 white spots, and no trace of the spots at the anal angle. In this species there is a black spot 

 between the lobe and the tail, which does not occur in T. punctum.

Upperside. Male. — Green-blue. Anterior wing with the costal margin and outer half 

 dark brown : the discal spot small, round, rufous. Posterior wing w r ith one tail : the apex and 

 outer margin dark brown. 



Underside dark rnfous and grey. Anterior wing crossed near the outer margin by a 

 linear band of five white spots bordered inwardly with brown. Posterior wing with a white 

 line before the middle : crossed beyond the middle by two bands of linear white spots bordered 

 with brown : anal angle with the lobe and a spot near it brick -red marked below with black, 

 the space between them irrorated with grey : a submarginal white line. 



Exp. 1^% inch. 



In the Collection of W. C. Hewitson, from Rio de Janeiro. 



This is nearly allied to T. punctum, but of different form ; the white spots on the underside 

 of the posterior wing are differently placed, and the male has the white spot below the base 

 which is only on the female of T. punctum.
