Duration of individual instars, accumulated time at the end of instars, duration of the brooding periods, and the number of young released during each instar for the animals primiparous during the fifth instar. The duration of each instar is given with respect to the ordinate in hours. The average duration is the point where the bars intersect while the length of the vertical bar represents two standard devi- ations, one on each side of the mean. The point of intersection also represents the accumulated time with reference to the abscissa and the length of the horizontal bar represents two standard deviations from the mean. The duration of the brooding periods is in the same terms as the duration of the instars with the solid circles denoting the means. The number of young is given with respect to the right ordinate. Here also the vertical length represents two standard deviations and the open circles the means. so 70 60 50 } i '40 30 20 10 DURATION OF INSTAR 6 / 8 9 10 II 12 13 14 15 16 // IB 19 20.
