feret to have to add another species to the already alarming 
f insects which attack the foliage of the apple. On the ‘26th 
te my attention was called by the owners of the Home Nur- 
it Normal, to an injury to the fresh and tender foliage of 
young apple trees; and, upon investigation, I found that a 
3 leaf-hopper of the family JassidiP was partly responsible for 
schief. _ This species occurred upon the leaves in such numbers 
n walking between the rows, one would drive them upwards 
ids. A careful examination showed that from two to six or 
were present upon every young leaf, with their beaks inserted, 
g the leaves to curl, and shrivel, and turn first yellow and then 
. At this time nine-tenths of the specimens were in the larval 
ial stages, only a very small number having yet acquired their

ant upon young apple trees at Centralia. The majority of 
were now fully developed adults, but all the stages are repre- 
: in our collections. The effect at Centralia was as apparent 
| Normal, in the curling and discoloration of the leaves.
