MEETINGS OF THE ENTOxMOLOGICAL BRANCH. 



Meeting No. 20 was held at Dr. Fletcher's rooms on Feb. 



2nd, 1905. The chairman, Dr. Fletcher, opened the meeting 



with an address on the use of Insects in Nature Study, pointing 



out the difficulties of using and preserving such small and fragile 



objects. He advocated the examination of specimens out of class 



and the teaching in class from enlarged charts. He opposed 



strongly the passing of specimens around an audience while a 



speaker was delivering an address, on account ot the confusion 



thus caused. Suggestions were made as to species of common 



insects which would be particularly suitable for study by students, 



each of whom should have the same insect under consideration 



at the same time. Insects mentioned were the Clouded Sulphur 



butterfly [Colias philodice) of which eggs could be obtained easily 



by enclosing a female in a gauze bag over a plant of white clover, 



planted in a flower pot. Each students could easily provide the 



food plant and secure the e^^ laying female. The Camberwell 



Beauty, the Small Tortoise-shell, the Graptas and Cabbage White 



butterflies, all of which could be easily obtained and all of which 



had short life-histories were also recommended. 



Mr. D. A. Campbell in discussing the address gave his expe- 

 rience of ten years in teaching natural science and nature study. 

 He had noticed the same difficulty of confusion in the class but be- 

 lieved in making the students examine the specimens very carefully 

 and thought that they did this better when in class at a specified 

 time than outside whenever opportunity arose. Another difficulty
