Applying the factor analysis to the values standardized from the measured values for instars in seven body parts of A. dallasi, it is summarized as follows: 1. All seven aspects are found to have the four growth factors. 2. The first factor is acceptable as a general factor and a growth promoting factor, whereas the rest three factors are indicated as a group factor in most cases. 3. The seven aspects are classifiable into three groups- the first group of the body length, the middle leg and the hind leg, the second group of the forg leg, and the third group of the width of pronotum, the antenna, the rostrum. But the second group is similar type to the first group in the influence of the factors. 4. The communality of the middle leg is the highest, while that of the body length is the lowest. The uniqueness of the middle leg is the lowest, while that of the body length is the highest. 5. The contribution of the growth factor tends to inrease according to the development of the instars. 6. The correlation for a young instar larva has a tendency to become low, but that for an advanced instar larva tends to become high.
