Slightly larger than T. phhyyas, with the black markings more heavily indicated. 



M.-VLE. — Primaries similar to those of T. dijficilis, but with the magenta-coloured 

 apical band narrower and more purplish in tint, this band being restricted to five

 nervule ; a small dark spot visible between the second and third median nervules. 



Expanse 2'1 inches. {Spec, ex Mcdverti, Natal ; Cecil H. Barker ; Triincn Coll.)
