Abstract
THE follicular epithelium in insects is said to secrete the chorion after the egg is fully formed. According to Snodgrass1, the follicular epithelium secretes a substance which is discharged over the fully formed egg and there hardens to form the chorion. Wigglesworth2 is also of similar opinion. The subject has also been touched upon by Biedermann3, Cappe de Baillon4 and Beament5.
