First Instar : body dull black, covered with numer- ous jet black branching spines. Head, glistening black, covered with short simple vibrissae. The first thoracic segment bears three branching spines on each side, the two largest pointing some- what anteriorly. There are two white points close to the juncture with the head in the mid-dorsal line, and eight or ten similar points close to the posterior border of the segment, the remaining portions being black. The second dorsal segment has a few white points (6 or 8) close to its posterior border. This segment bears six large branch- ing spines, and two rudimentary spines near the middorsal area. The third segment is solidly black except for two minute points on the anterior border, frequently hidden by the segmental fold. 83.
