On the middle line of both the ninth and tenth segments is an orange or coral- red retractile tubercle. In about eight days the caterpillars shed their skins or molt, after which they are about two fifths of an inch long, the body hairs are relatively longer, though the tufts on the fourth and fifth segments are not so large. About the middle of May (15th to 20th), the second spring molt occurs. The cater- pillar is now about three fifths of an inch long, the yellow markings of the body being more apparent, and the brown tufts on the back less prominent. In this stage the upper hairs of the tubercles along the sides of the abdo- minal segments are a distinct white color, forming a band of white dashes along either side of the cat- erpillar, which is so.
