(1) =Heliconius charitonius=, Linnæus, Plate VIII, Fig. 5, ♂ (The Yellow-barred Heliconian; The Zebra). This insect is a deep black, the fore wings crossed by three bands of yellow: one near the apex; another running from the middle of the costa to the middle of the outer margin; a third running along the lower edge of the cell, and bending at an obtuse angle from the point where the first median nervule branches toward the outer angle, at its outer extremity followed by a small yellow dot. The hind wings are crossed by a somewhat broad band of yellow running from the inner margin near the base toward the outer angle, which it does not reach, and by a submarginal curved band of paler yellow spots, gradually diminishing in size from the inner margin toward the outer angle. There are also a number of small twinned whitish spots on the margin of the hind wing near the anal angle. The body is black, marked with yellow spots and lines; on the under side both wings are touched with crimson at their base, and the hind wings have some pale pinkish markings near the outer angle. The caterpillar feeds upon the passion-flower. The chrysalis, which is dark brown, has the power when disturbed of emitting a creaking sound as it wriggles about, a property which is reported to be characteristic of all the insects in the genus. This butterfly is found in the hotter portions of the Gulf States, and is rather abundant in Florida, in the region of the Indian River and on the head waters of the St. Johns. It ranges southward all over the lowlands of Mexico, Central America, and the Antilles. SUBFAMILY NYMPHALINÆ (THE NYMPHS) "Entomology extends the limits of being in new directions, so that I walk in nature with a sense of greater space and freedom. It suggests, besides, that the universe is not rough-hewn, but perfect in its details. Nature will bear the closest inspection; she invites us to lay our eye level with the smallest leaf and take an insect view of its plane."--THOREAU. "My butterfly-net and pocket magnifying-glass are rare companions for a walk in the country."--WILLIAM HAMILTON GIBSON, _Sharp Eyes_, p. 117.
