May 4, 1921 proceedings: entomological society 217 



Among the experiments performed with these parasites several were con- 

 ducted to obtain information on the longevity of the adults, with the following 

 results : 



Sixty-five adults were placed in vials without food, all the males dying 

 within 3 days and the females within S days. 



Forty adults were place in a vial with a piece of cotton soaked in sugar 

 water; all the males died within 3 days but all the females, except 1, were 

 living on the 13th day and all were not dead until the 17th day. 



This experiment would seem to indicate that either the female alone took 

 nourishment or at least they were the only ones to benefit by food with in- 

 creased length of life. 



Mr. RoHWER reported for the Executive Committee that the committee 

 had decided on the National Museum as the meeting place, at least tempo- 

 rarily, and asked for an expression of opinion by the members. Several 

 members expressed themselves as pleased with the arrangement.

The 335th meeting of the Society was held December 2, 1920, in Room 43 

 of the new National Museum building. Vice-President Gahan presided and 

 there were present 36 members and 3 visitors. 



The Corresponding Secretary reported that he had been advised that the 

 collection of cavern coleoptera secured from Austrian entomologists in ex- 

 change for food parcels had been sent. The collection contains 100 species 

 representing many interesting genera not represented in the National Museum 

 collection. The Secretary stated that these insects are to be accessioned as a 

 gift to the National Museum through the Entomological Society. 



Dr. H. E. Ewing, of the Bureau of Entomology, and Mr. C. F. W. Muese- 

 BECK, of Cornell University, were elected to membership.

Regular program 



E. R. Sasscer: Quarantine work on the Mexican border. 



Mr. Sasscer prefaced his paper with some remarks concerning the early 

 history of the Pink Bollworm in the Laguna District of Mexico, and the place- 

 ment of inspectors at the main avenues of entrance along the Mexican border 

 to prevent the entry of this insect in cotton seed concealed in freight cars 

 and other vehicles, and in passengers' baggage. It was pointed out that at 

 the present time the Federal Horticultural Board has twenty-four inspectors 

 located at various ports on the Mexican border, and that fumigation houses 

 of sufficient size to fumigate freight cars are located at Browns\alle, Laredo, 

 Eagle Pass, and El Paso. Two of these houses will accommodate from one to 

 fifteen cars, one from one to six cars, and one from one to eight cars. At 

 Del Rio, where there is at present no railroad connection between the United 

 States and Mexico, a small house has been erected to fumigate wagons, 

 automobiles, etc., requiring such treatment. He stated that steps were now
