The present material has on the front wings the internal triangle free (3 wings 3, 3 wings @ ) or 2-celled 
(13 wings $, 1 wing 9), the two post-triangular rows increasing to three rows near the level of origin 
of the subnodal sector or, in the Haytian female, near the level of the nodus.

i, Front wings with two post-triangular rows increasing to three rows at the level of origin of the subnodal 
sector, or 1—2 cells beyond, the internal triangle more often 2-celled but sometimes free, irrespective of 
locality (Misantla, Teapa, Pantaleon, Santa Lucia) or symmetry. Only one male, that from Guatemala 
in McLachlan’s collection, has a dark spot at the distal angle of the discoidal triangles.
