The red color soon pervades the whole body, except the firgt two abdominal joints, which remain yellowish, and the members, which remain pale. After the Jtrst molt (Fig. le) the red is quite bright vermilion, contrasting strongly with the pale band across the middle of the body, the prothoracic joint is relatively longer, and the metathoracic relatively shorter. The head and prothorax are dusky and coriaceous, and two broad marks on mesothorax, two smaller oues on metathorax, two on the fourth and fifth abdominal sutures, and one at tip of abdomen are gen- erally visible, but sometimes obsolete; the third and fourth joints of anteunaj are dusky, but the legs still pale. After the second molt (Fig. 1/) the head and thorax are quite dusky, and the abdomen duller red, but the pale transverse baud is still dis- tinct ; the wing-pads become appai'ent, the members are more dusky, there is a dark red shade on the fourth and fifth abdominal joints, and, ventrally, a distinct circular dusky spot covering the last three joints.
