Since the apperarance of a paper in the May and June, 1903, numbers of the Canadian Entomologist, the writer has received for study either eggs or larvæ of several species of Apantesis, information as to the earlier stages of each of which was limited. The past three seasons in Canada have not been remarkable as to the abundance of material to collect, and Arctians, like many other kinds of moths, have been very scarce. Consequently not as many species have been received for study as had been hoped.
