Data upon the first four instars of Thermobia domestica (Packard) appeared in a previous paper (Adams, 1933b). The rapid growth of the sensory appendages was emphasized. Nothing was written, however, about the duration of these early instars or the variations to be found in the dimensions of individuals within a given instar.
