The application of Mr. Adolph Biersach was received and referred 
to the Board of Directors. Designations were received from Mr. A. C. 
Katze-Miller and Mr. R. M. Phillip. 
Dr. Barth gave an informal talk on certain habits of the solitary- 
wasps. He outlined some observations made during the past summer, 
relative to the ability of certain species to recognize its prey after 
the prey has been taken away from the wasp. 
He had observed that nests of the digger wasps are not so num¬ 
erous and not so deep in wet weather as in dry. 
Messrs. Peckham, Monroe, Graenicher and Dernehl took part in 
the discussion. 
Mr. Russel read an article by Theodore Roosevelt on Protective 
Coloration, this article being a summary of a book by Thayer. 
Messrs. Monroe, Peckham,* Graenicher, Dernehl and Barth dis¬ 
cussed the subject. 
Mr. Monroe demonstrated a hybrid aster which had arisen from 
the crossing of two very widely different plants. 
The meeting then adjourned.

importation and interstate transportation of nursery stock and to
