Monotarsobius nihamensis MURAKAMI is a species described by the author in the VI Report of this series. The adult female of this species lays more than 30 eggs in summer. Egg is milky white in color and shows a spherical form of 0.4-0.5mm in diameter. The incubation period of the egg at room temperature of 18-31℃, was about 25-40 days. The foetus usually attained complete maturity on the third year. The hemianamorphic development of this species is divided into twelve growing stadia which have such morphological characters as are shown in Table 1. 1. Leg-buds of larvae of this species have two characteristics: (1) Large leg-buds of the first larval stadium are not so long as that of L. pachypedatus TAKAKUWA or B. asperatus KOCH, and (2) The first three pairs of leg-buds in the second to fourth larval stadia always curve slightly towards the inside (See Fig. 1, A-C and Report III). It is not evident whether these characters are general or specific. 2. Number of articles of antennae is related to the growing stadia as summarized in Table 1. Extent of variation in two stadia of Agenitalis is shown in Table 2. 3. As shown in Table 3, spines on the legs in each growing stadium increase in number and enlarge gradually from the third larval stadium. Among the spines, VFm, VTim, VPp and DTia appear at the earlier stadium, and 1.-6. DPp, 1.-4. VPp and 12.-13. VFp do later. The relation between spinulation and growing stadium is clear from Table 3. 4. Number of coxal pores in each growing stadium and extent of variation are as shown in Tables 1 and 4.
