Greatly enlarged. (Original.) rather short, all about the same length, situated in the positions of the spines of the first stage, each with several short branches or notches bearing fine setae; the sub- dorsal spines on joints 3 and 4 have several of these branches modified into quills with short sharp points, which are the urticating spines. They are developed in this stage only on the subdorsal spines of joints 3 and 4 (mesothorax and metathorax), and only three on each spine.
