The niewly-hatched larva is nearly uniform gray in color, with small black tubercles and no visible evidence of striation. The head is round and prominent and nearly twice as wide as the body, and the hairs of the body are sparse and about as long as the width of the head. ThefuU-gwvjH larva.—The larva when mature is bluish-gray above, with conspicuous transverse black stripes. The head is yellowish or light brown, the thoracic plate mottled (fig. 12, f/), and each segment has three or more well-defined, nearl}' straight or curved, transverse stripes. (On the second and third thoracic segments the first stria curves forward between the anterior tubercles.) The dorsal tubercles,.

There is a wide stigmatal line of bright yellow extending from the second to the last segments, and above each spiracle there is a large prominent black tubercle. The ventral surface is green, somewhat mottled with jj^ellowish, and the tubercles bear each a long, black hair about half as long as the width of the body. In form the larva is subcylindrical, moderately slender, about six times as long as wide, and the segments of the body show strongly at the sides. The length of the mature larva is al)out six- tenths of an inch, 15""" in repose, 17"
