A SURVEY OF THE ZOOCECIDIA ON SPECIES OF
HICORIA CAUSED BY PARASITES BELONGING
TO THE ERIOPHYIDÆ AND THE ITONIDIDÆ
(CECIDOMYIIDÆ).[1]
Bertram W. Wells.
This paper is primarily an attempt to present adequate descriptions of the types of 30 itonid (cecidomyid) and 2 eriophyid (mite) galls, collected by the writer on hickory leaves. It is believed to contain sufficient new material to warrant its publication in advance of a general survey of N. E. United States zoocecidia, of which it will form a part. The data is based on collections made in Connecticut, Ohio and Kansas, most of the material however, being taken in Ohio.
In addition, those forms (few in number) previously described which have not been seen by the author, have been added, so as to give a character of completeness to the survey of the two groups of galls.
