NOCTUIDÆ.

This extensive assemblage of moths, commonly known as noctuas, and locally as "millers," "owlets," and "buzzards," has been divided by Staudinger into five sub-families—Acronyctinæ, Trifinæ, Gonopterinæ, Quadrifinæ, and Hypeninæ. These divisions are here adopted, and the arrangement of species is adhered to pretty closely, except in the Trifinæ, where it has been considered necessary to make sundry alterations so as to fall more in line with later classification, at least so far as concerns genera.

The eggs of species in this family are round and somewhat flattened in shape, and the shell is fluted or netted. Some few examples of these have been figured.

Most of the larvæ conceal themselves during the day, in the ground, among low herbage, or in spun-together leaves, and only leave their retreat at night to feed. Most kinds change to the chrysalis state underground, but some pupate among leaves or in chinks of tree bark, etc.

With some few exceptions the moths fly only at night, by far the larger number will visit the sugar patch, and others come readily to flowers or to light.

Distribution abroad will only be referred to where this is restricted in Europe, or extends far beyond European limits.
