Thereafter at weekly intervals, each pupa was checked for the initiation of adult development, as judged by the retraction of the leg epidermis. In the experimental results summarized in Table I, it will be observed that a considerable period was required for the initiation of adult development at all of TOP 60- 50 40 30 LJ I- < 20 10 INITIATION OF DEVELOPMENT. 50 — 40- LJ LU h- < CC 20 10 COMPLETION OF DEVELOPMENT.
