Proterpia
Butterfly.--Even deeper orange than the preceding species. The hind wings are, however, less pointed; the veins and nervules are black at their ends, and the costal margin of the fore wings is evenly bordered with black, which does not run down on the outer margin as in T. gundlachia. Expanse, 1.50-1.75 inch.
Early Stages.--Unknown.
Proterpia is found in Texas, Arizona, and Mexico.
