On the evening of the 31st July, 1899, while collecting moths at the electric light, close to the entrance to the Central Experimental Farm, I was fortunate enough to secure a female of Euprepia Caja, L., var. Americana, Harr. I enclosed her alive in a small box over night, and by the morning she had laid nine eggs. From these eggs five larvæ hatched, and as I have succeeded in bringing two of these through all their stages, my notes may be of interest to some of the readers of the Canadian Entomologist.

Egg.—Semi-ovoid, about .75 mm. in width, at widest part; pale yellowish, smooth, shiny.
