Egg.—Globular, slightly flattened above, more decidedly so below; lower half smooth; upper half deeply grooved, the interspaces rounded and marked with fine transverse impressed lines ; whitish, the upper half sometimes dotted with dark brown ; transverse diameter nearly ½ mm. [The top of this egg closely resembles that of the unarmed Rustic (Agrotis saucia) figured in Riley's 8th Report, page 37, fig. 24.]
