Abstract
SUMMARY: A histochemical and fine structural study of the vitelline membrane and chorion was carried out. Following the uptake of protein at the oöcyte plasma membrane during yolk synthesis, the egg membranes are laid down in sequence in the intercellular space between the oöcyte and the follicle cells. The follicular epithelial cells alone contribute towards their formation. The structure of the chorion is much simpler than that of Bombus, the only other hymenopteran previously investigated.
