Lithobius pachypedatus TAKAKUWA, which comes under the subgenus Archlithobius STAUXBERG, is one of centipedes found commonly in Japan. This paper deals with its larval stadia. 1. This species has five anamorphic stadia, each of them showing such morphological characters as summarized in Table 1 and Figures 1-9. 2. Antenna of larva in the third stadium consists of 17 articles and this article number is not variable. 3. Larva of the first stadium has 2+2 teeth and the tooth number is constant during its life. 4. The order of the anamorphic development of leg-bearing segments of this species is given in Table 2. A morphological importance was found by studying the eight tergites from the last. Namely, the 8th, 10th, 12th and 14th tergites have each stage as an embryonal tergite, while each of the others (the 9th, 11th, 13th and 15th) has not it. This remarkable difference between the two groups of those tergites arises from that in the size of the tergites.
