PL. V
The butterflies of this genus mimic the Heliconians in form; their fore wings are long and narrow. The cell in the hind wing is open. There are a number of species, two of which are found in the hot parts of the Gulf States. The larvæ resemble those of the genera, Dione and Euptoieta, and, like them, feed on the Passifloraceæ.
(1) Colænis julia (Fabricius) (Julia). [Plate V], ♂.
The figure on the plate obviates the necessity for a description. The insect occurs sparingly in Florida and in Texas, especially about Brownsville. It is very common in Mexico, and thence southward. Expanse 3 to 3.5 inches.
(2) Colænis delila (Fabricius), Delila.
Imagine all the dark markings shown in the figure of Colænis julia on [Plate V] effaced, and replaced by the lighter ground-color, only all of the wing a shade paler and yellower, and the fore wings a trifle more pointed at the tip, and you have a mental picture of this species, which has the same range as the one shown. Expanse 2.75 to 3.3 inches.
