 outer margin from apex to first median branch blackish ; a black spot on the inner margin 

 near external angle ; basal tuft rosy : secondaries rose-colour, becoming ochraceous at outer 

 margin ; two large black snbanal spots : thorax brownish lilacine, with a broad black-brown 

 central longitudinal stripe, widening behind ; abdomen brownish lilacine, darker in the middle

Nearly allied to the preceding species, Ijut larger, greyer, with the outer margin of the 

 primaries less strongly dentated, the spot near external angle smaller, and the dusky lines 

 different in direction; the secondaries altogether deeper in colour, with broadly diffused 

 smoky brown outer border, and smaller black spots at anal angle ; thorax darker, with less 

 distinctly defined central blackish stripe : wings below altogether darker and greyer, the 

 bordei-s and lines smoky brown ; body below darker. Expanse of wings 3 inches 9 lines.

Differs from T. roseipennis in the same degree as do the other species of the genus.
