Genus EUPTOIETA Doubleday
PL. VII
There are two species of this genus found in the United States. The butterfly has the cell of the fore wing closed by a feeble veinlet and the cell of the hind wing open. The antennæ and palpi resemble those of the genus Argynnis. The under sides of the wings are not spotted with silvery marks.
(1) Euptoieta claudia (Cramer), The Variegated Fritillary. [Plate VII], Fig. 1, ♂; Fig. 2, under side.
The caterpillar feeds upon the leaves of Passion-flowers and violets. It is reddish yellow in color, with black spines on the segments, white spots on the back, and dark brown bands running the long way on the sides. The chrysalis is pearly white mottled with black spots and streaks. The insect ranges from southern New England south and west, and is reported from as far north as Alberta. It goes as far as Argentina in the south. Expanse ♂, 1.75 to 2.25 inches; ♀, 2.25 to 2.75 inches.
(2) Euptoieta hegesia (Cramer), The Mexican Fritillary.
Very much like the preceding species, only the wings, especially the hind wings, have very few dark markings, except about the borders, and the insect is smaller. Expanse ♂, 1.6 to 2.25; ♀, 2.25 to 2.5 inches.
Found in Texas, Arizona, and southward.
