[For an account of experiments conducted in England by Dr. Wallace, which 

 unfortunately were a complete failure as far as rearing the moth went, see an essay 

 by that gentleman in " The Transactions of the Entomological Society of London," 

 3rd series, vol. v. pt. 5. Longmans and Co. The results of an experiment which 

 give the greatest hopes of success, will be found in "The Entomologist" for 

 October, 1867. ED.]
