A/enlum fleshy, narrow at base, broadening toward the rounded tip. Apparently no ligula. Head small, yellowish with a small aspersion of black pigment on occiput. The hody-inttgiiment exhibits under the micror scope a beautifully arranged black pigmentation with fine canals between them. I-fgs, the mid- dle and posterior pairs slightly longer than the anterior. The coxal supports are prominent, coxje short, trochanter very short and apparently connate with the former, but the cast-off skin plainly shows a ring of the former going over one of the latter, thus lacking the internode of the other articulations; femur and tibia with long thick bristles, both pieces compressed, the latter slightly shorter than the former; claw simple and with two spines at middle. ProlJiorax gradually getting broader toward base, as long as two of any of the other segments together, an impression along the margin, the anterior transverse line of which reaches the middle of the segment. A/esothorax a little wider than the preceding. Metathorax, the widest of all the body-seg- ments. About four times wider than long. The abdominal segments gradually diminish in width toward pygidium. The three thoracic segments and the first eight abdominal segments with a short bristle at base of marginal scute and one such bristle at tip, the latter bent back and downward. Ninth dorsal segment at tip with a cylindrical, immovable spine of the length of any of the terzal scutes. Spiracles, nine pair; first and largest near base of prothorax a little behind and above the anterior coxa. Second to inclu- sive fifth spiracle in the pleurites anteriorly of each of the first five abdominal segments, the last three spiracles are much smaller and corres- pond with the sixth, seventh and eighth seg- ments ; ninth segment witliout spiracle.
