• The fine structure of the prothoracic gland cells of the silkworm, Bomyx mori, was examined during metamorphosis from larvae to pupae using an electron microscope. The most conspicuous finding in the prothoracic gland cells of pupae was a disappearance of the circum cellular convering membrane, a kind of basement membrane, fuzzy or spongy in appearance. This covering membrane was developed and thick in the nymphal stages. Cytoplasm was abundant and the peripheral cytoplasmic processes were also prominent in the larval stages. At the pupal stage, however the cell surface became smooth. A great number of hemocytes were also observed with the electron microscope.
