*' In the study of the beet insects it was found that the most common 

 species that are usually known as ' weed-feeding' forms were the first 

 to attack the beet. All these that attack the common garden as well as 

 field weeds also attack the beet. These are such as feed upon the ^ pig- 

 weed,' the Amarantus, the purslane, ' tumble-weed,' etc." 



In closing, Mr. Bruner requested that all entomologists assist in the 

 further study of these beet insects by sending him the names of, or any 

 notes in relation to, such species as are not included in his list given 

 above. He expects to continue the study the coming: year with a view 

 of publishing results in the form of a special bulletin from the Nebraska 

 Agricultural Experiment Station. 



Mr. Fletcher asked whether there was any practical remedy for the 

 Anthomyia attacking beet-root leaves. 



Mr. Howard asked whether Silpha opaca has been found feeding on 

 beets in this country ; it is a well known enemy to this crop in Europe. 



Mr. Bruner did not know that this was so from personal observation. 



Mr. Fletcher expressed interest in the habits of Collops, He had

Mr. Smith had found it commonly on golden rod. 



Mr. Smith related the following :
