emy, Jourdan, Siebold and others. They all agree that 

 Avliile parthenogenesis is rare in this species, it docs 

 sometimes occur, and it is known that the partheno- 

 genetic eggs give rise to fertile males and fertile females, 

 which may unite sexually and thus produce fertile eggs. 

 Dr. Kipp has reared another form, SmerintJius iwpuli, 

 from eggs fertilized by a male which hatched from a 

 parthenogenetic egg, and laid by a female which had 

 been reared in the same w^ay. 



In Bronn's Klassenund Ordmingen, Gerstaecker gives 

 the following list of moths in whicii par:henogenesis 

 has been observed, with the name of the observer. The 

 list might be greatly enlarged by the addition of cases 

 whicli have been recorded since its compilation, but 

 it is sufficient for our purpose, whicli is simply to show 

 that the fact has been verified repeatedly by many ob- 

 servers.
