As supplementary to my remarks on this pretty creature in the August number of the Can. Ent., I would say thaton June 6th a friend gave me a captured female Luna. For two or three nights I used her as a trap to entangle unwary males, but in vain as far as my cabinet was concerned; the weather was cold. On the 7th,8th and 9th, during the silent watches of the night, she deposited in her place of confinement, in all, about 100 eggs of a dark brown or chocolate color, flattened at the sides, smooth and about .005 of an inch in length: the sides were of a lighter shade.
