A 1919 COLLECTION OF CICADELLIDiE IN THE 

 ENVIRONS OF BOSTON. 



By George W. Barber, 

 Cereal and Forage Division, U. S. Bureau of Entomology. 



The following list of leaf-hoppers represents a collection made 

 entirely during the second half of the 1919 collecting season in 

 towns usually nor further than fifteen miles distant from the State 

 House in Boston, Mass. It represents only very incomplete col- 

 lections, mostly specimens hastily taken at odd moments while 

 engaged in other work. 



Very little appears to have been done in determining the Cicadel- 

 lid fauna of Massachusetts in any systematic manner, and the 

 present list may be regarded as an introduction to a more complete 

 study of these insects in the state. 



It is well known that the years spent in actively combating 

 injurious insects such as the gypsy and brown-tail moths, the elm 

 leaf beetle, and the European corn-borer in this section have left a 

 very noticeable effect on the prevalence of the leaf -eating insects.
