A 1919 COLLECTION OF CICADELLIDE 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.

19201 Barber-A 1919 Collection of Cicadellidce 147 It is interesting, therefore, to notice that the effect on sucking insects is evidently not so marked for the accompanying list of fifty-five species and varieties, representing twenty-six genera, taken so unsystematically during but half of one season, cannot nearly represent the total fauna, in this group, that are present. Two European species, Deltacephalus striatus Linn., and Allygus mixtus Fabr., are herein reported both taken in the Town of Med- ford.
I am indebted to Mr. E. H. Gibson, U. S. National Museum, and especially to Mr. D. M. DeLong of Harrisburg, Pa., for kind as- sistance in determination of species unknown to me. 1767-Agallia sanguinolenta (Prov.) .
