mentions this character in his description of C. orina in the following 

 words : " les deux lignes medianes fines, blanches, disposees en trapeze 

 plus ouvert par le bas que chez Trapezina." Except that the hind wings 

 are paler, I hardly see any other difference and I do not see the discal 

 point beneath. In one specimen the " points terminaux " are " bien 

 marquds," as in the var. A of trapezina, but the wings are not " teint^s de 

 rouge — brique clair."
