On eggplant the greater number of the eggs have been found on the underside of the leaves, although they are also placed on the surf ace and some- times on other portions of the plant. "While as many as four eggs have been found together, they are usually placed singly or in groups of two or three eggs each. Where more than one egg occurs they are placed one above another. Surrounding the egg and extending from it in the plane of its greatest circumference, to form a more or less rectangular flake, is a thin, transparent layer of membranous substance having a brownish tinge. Covering this, almost without exception, is a second, larger flake of the same material. These are attached to each other at the end where the flake inclosing the egg is attached to the surface upon which it is placed. Eggs were first noted in the field at Baton Rouge, La., on May 11 and were present as late as September. PERIOD OF INCUBATION. During June the period of incubation of eggs kept in the insectary was quite constan
