Abstract
The subspiracular glands as found in Lepidoptera are the subject for this investigation.The embryonic origin from the ectoderm is described.Details of the cytology and morphological development of these glands in the egg are reported. Before hatching of the eggs, the glands undergo a nuclear secretion. The number of cells in each gland remains constant throughout the intraovular period.The development of the glands is related to the development of other tissues.
