According to the writer's microscopic observations from the latter part of July of 1954 to the early part of August of the same year, the male A. Yamamai moth ejaculates in the Bursa Copuatrix of the female moth about half an hour after copulation and the shift of the spermatozoon to the female receptaculuin seminis follows for 6-7 hours thenceforth. The ejaculation of the male A. pernyi moth, on the contrary, is 25 minutes after copulation and the shift of the spermatozoon to the receptaculum seminis is 4-5 hours after the incident. In comparison with the rapid process seen in Bombyx mori, in which the ejaculation takes place 15-20 minutes after copulation and the shift of the spermatozoon is only one and a half hours henceforth, the extinguished retardation should be considered characteristic to these wild silkworms.
