1. In Table 1, the variation in number of articles of antennae of L. pachypedatus in all hemianamorphic stadia is presented. a) So far as the present study is concerned, the variation of articles of antennae occurs commonly at epimorphic stadia, and the variation is a normal individual variation at the stadium of immaturus, while it is one-sided at the others. b) At the stadia from praematurus to maturus, the variation takes an exclusively plus direction. This phenomenon seems to suggest a differentiation of articles of antennae. c) In this species, typical numbers of antennae are 20 (20-26) articles. 2. As summarized in Table 2, the numbers of coxal pores and the extent of its variation in variation in each growing stadium increase and enlarge gradually from the fourth stadium of larva. But the increase does not always correlate to the number of passed molting (Table 3). The coxal pores of this species usually are 5, 5, 5, 4 (3, 4, 4, 3-6, 7, 7, 6) in number.
