as larvae, they descend at the end of the second summer to pupate. They 

 are then caught, and thrown into a pile of hot earth. After partial cooking 

 they are dried in the shade, and thereafter will keep indefinitely. The 

 specimens shown were eleven years old. There is but one brood, and cater- 

 pillars can be taken only in alternate years. 



Mr. David Fairchild spoke upon the edibility of certain borers with 

 which he had experimented. 



Prof. A. S. Hitchcock reported progress toward agreement among the 

 various botanical codes. The desire is to unite the American and Vienna 

 Codes and to agree upon the principle of types.

L. O. Howard: Some views of the fight in southern France last summer 

 against the Moroccan locust. (Illustrated.) 



This locust lives all around the Mediterranean coast, and at times is threat- 

 ening to vegetation; it was especially so in 1920 in southern France in the 

 sheep pastures. The government detailed soldiers to assist farmers in the 

 campaign against the locusts, the farmer furnishing lodging, food, and all 

 materials. In early morning when the locusts were comparatively sluggish, 

 they were driven to the center of the fields where a flame was played over 

 the mass of insects. A poisoned mash could not be used on account of the 

 scarcity and expense of materials. Views were shown of the farm quarters, 

 the fields and locusts, and the methods of fighting the insects. 



Dr. Howard also availed himself of the opportunity to visit the home of 

 Henri FabrE, at Avignon. The home is kept by one of his daughters 

 exactly as left by Fabre at his death, five years ago. Fabre was very active 

 to the time of his death, and in his garden there remain many plants which 

 he brought from the Alps. Views of the house, garden, and the medal 

 which was struck in commemoration of the esteem in which Fabre is held 

 by the French were shown. 



S. F. Blake: Sexual differences in coloration of the spotted turtle. 



This paper will appear in full in the Proceedings of the U. S. National 

 Museum. It was discussed by Drs. Shufeldt and Howard.

Brief Notes and Reports of Literature 



Dr. C. L. Shear called attention to an article in Science concerning the 

 formation of a committee of 14 by the British to aid men of science in Russia, 

 the main idea being to provide literature for Russian scientists. The meet- 

 ing instructed the Executive Committee to give attention to the matter of 

 providing scientific literature to Russian scientists, and instructed the So-
