Studies in Variation, inelnding breeding- experiments, can 

 be carried on with several of the groups. This line of re- 

 search is specially attractive here, for six or more generations 

 mav be had per year. 



Of these special subjects, those with reference to Hymen- 

 optera have several of the members of the Society specially 

 interested in them: the Aculeates — Messrs. Giffard, Williams, 

 Timberlake and Bridwell ; the Parasitica — Messrs. Pullaway, 

 Timberlake, Bridwell and Swezey. 



In the Lepidoptera, Mr. Swezey has been carrying on re- 

 searches in most of the lines mentioned. 



In Coleoptera. Messrs. Giffard, Bridwell and Swezey are 

 especially interested in certain problems, and Dr. Perkins is ' 

 still doing systematic work with the beetles. 



The Diptera are receiving less attention than some of the 

 Orders. They have been considerably neglected in the past.
