The name of William Stark Smith was proposed for membership by Mr. 
Clarence Allen. The nomination was referred to the board of directors. 
Dr. S. Graenicher gave a discussion : The Influence of the Color and 
Odor of Flowers on Insect Visitors. He gave a brief discussion of the 
more important experiments by various entomologists and their results, 
up to date: Muller’s experiments with bees, moths and butterflies by 
which he concludes : that color is the influencing agent in flower visitation. 
Plateau thinks color is of little significance; according to his observations 
odor is the principal influence. Insects have little color sense. Peckham 
by his work finds that food is the chief factor. Dr. Graenicher gave a 
very interesting and detailed account of his own experiments, in which he 
finds abundance of evidence in favor of the conclusion that it is not color, 
nor odor, but the food quality of the food furnished by the flowers; and 
that the return to a particular plant was determined by memory of the kind 
of food and of its place, made known by an extended environmental exami- 
nation. 
In the discussion which followed Mr. Russel gave an interesting obser- 
vation in regard to environmental observation by insects. 
Dr. Peaslee followed, presenting a number of beautiful colored slides of 
wild flow’ers. 
On motion the society adjourned.
