Butterfly.--Easily distinguished from all other species in our fauna by the pointed hind wings, margined on the outer border with black, and by the heavy black border of the fore wings, deeply excised inwardly, recalling the fore wing of the species of the genus Meganostoma. Expanse, male, 1.75 inch; female, 1.85 inch.
Early Stages.--We do not, as yet, know much about these.
T. mexicana is very common in Arizona, and occurs also in Texas. It is abundant in Mexico.
