 stroyed by use of poison. Bran, sugar and arsenic were mixed 

 and left where the insects could gain access to the mixture. 

 Whether this can be made available in fields to protect grass, 

 oats, etc., is yet to be decided by actual trial.

 the same family as the bee moth, and to the same genus as the 

 corn-root web Avorm, Crambus zeellus Fernald, which has done 

 considerable damage in Illinois the past summer (1885).
