the beginning of March next, may cause them to emerge in their perfect state ; but 

 should they pass over that time unchanged, they will remain so until the following 

 spring: indeed, Mr. House, of Messrs. Garraway's nursery, Redland, who has been 

 very successful in the breeding of insects, assured me that he has had this moth break 

 its chrysalis after the almost incredible period of six years. My young friend, Philip 

 H. Vaughan, of Redland, has a chrysalis of Sphinx Ligustri, which has passed by the 

 period of its final change, and probably awaits the warmth of another June. Many 

 of your readers are no doubt acquainted with the length of time that frequently elapses 

 from the formation of the cocoon to the appearance of the moth of Cerura Vinula. I 

 have kept them for three years before I have been gratified with the sight of their trans- 

 formation into the winged fly. The pages of ' The Zoologist ' record the captures of 

 some specimens of Colias Edusa and C. Hyale most years, while frequently they are 

 seen in great numbers. May not similar (atmospheric ?) causes affect these, which have 

 affected Eriogaster lanestris, Sphinx Ligustri and Cerura Vinula ?
