Abstract

On May 27, 1919, an American elm on the Iowa State College grounds at Ames was found to be infested with European elm scale (Gossyparia spuria). Since the above date several other Iowa records have been added to our list and a considerable amount of information has been obtained regarding the distribution of this species in the United States and Canada through correspondence with State Entomologists, the U. S. Bureau of Entomology and Agricultural Experiment Station workers in states in which scale was thought likely to occur.
