 III. History of the nomenclature. IV. Times of appearance. V. Evidences of 

 growing scarcity in this country. VI. Experiments in breeding. VII. Varia- 

 tion : 1. General characteristics; 2. Lines of variation; 3. Sexual variation; 

 4. List of aberrations (striking aberrations are very rare) ; 5. Geographical 

 races. VIII. Suggested questions for further investigation. Mr. Gibbs discussed 

 some of the same points, especially referring to his own observations of the 

 growing scarcity of the species. Mr. Piatt Barrett gave his experiences of the 

 species for the past .50 years. Dr. Chapman, Messrs. Gibbs, Curwen, Piatt

 egerides from S. Devon, sent by Dr. Perkins, and read a long series of notes on 

 the characteristics, habits, and dates of the various broods. In the discussion

 growth, the species could pass the winter as a pupa. The Report of the Field
