I have obtained many egg-masses of this species the present season, and have had them deposited by moths reared in confinement. Even in a state of nature they are deposited quite irregularly, some fastened on one of the compressed sides, some piled on top of others, but most of them on the small end as in the closely allied Maia. The average length is 0.07, largest width 0.05, and greatest thickness 0.03 inch. They are compressed on two sides, and flattened at the apex, the attached end smallest. when first deposited they are pure cream color, with a translucent yellow spot on the flattened apex.
