species. In the study of the mites attacking apple and pear leaves 
in this State, all but Eriophyes malinus have been identified. Erio- 
phyes pyri is the most abundant and is responsible for the recent 
conspicuous injuries to apple and pear foliage. Lpitrimerus pyri 
and Phyllocoptes schlectendali have been quite numerous and appear 
to be more common here than on the Continent. The behavior of 
these two species in the future is a matter of interest as both seem 
to have possibilities of developing to greater economic importance. 
In addition to the above list of mites attacking pomes, another 
species, which is new and which has been designated Eriophyes 
malifoliae, is recorded for the first time. The known species of 
mites upon apple and pear may be separated by the accompanying 
table.
