The Cecropia Moth, Sainia cecropia (Sa'mi-a ce-cro^pi-a).— This is the largest of our Giant Silk-worms, the wings of the adult expanding from five to six and one half inches. The ground color of the wings is a grizzled dusky brown, espe- cially on the central area. The wings are crossed beyond the middle by a white band, which is broadly margined without with red, and there is a red spot near the apex of the fore wing just outside of a zigzag line. Each wing bears near its center a crescent-shaped white spot bordered with red. The outer margin of the wings is clay-colored. The larva is known to feed on at least fifty species of plants, including apple, plum, and the more common forest trees. When full grown it measures from three to four inches in length and is dull bluish green in color. The body is armed with six rows of tubercles, extending nearly its entire length, and there is an additional short row on each side on the ventral aspect of the first five segments follow- ing the head. The tubercles on the second and third thoracic segments are larger than the others, and are coral-red. The other dorsal tubercles are yellow, excepting those of the first thoracic and last abdominal segments, which with the lateral tubercles are blue ; all are armed with black bristles. The.
