Economic importance.—Mealy-bugs are capable of inflicting 
injury to the host plant in a manner similar to scale insects by 
sucking the sap from the bark and leaves. A number of species 
work upon the roots of plants. In the infested quince orchard 
some injury was undoubtedly done, as the insects sucked the sap 
from the limbs and twigs often from near the base of the buds. 
In this case the amount of injury is only-a question of numbers. 
Treatment.—As the insect is soft bodied, similar to the plant 
lice, and during the spring and early summer lives openly on 
the twigs, one or two applications of whale-oil soap, one pound 
to five gallons of water, would quickly check it. Scraping the 
trunk and large limbs during the winter where there is loose 
bark and painting with a strong solution of whale-oil soap, one 
pound to the gallon of water, would have a similar effect. 
IV. TWO APPLE LEAF MINERS. 
The minute caterpillars that mine into leaves are among the 
most common of the insect pests. A number of species work in 
the foliage of apple trees, but seldom in sufficient numbers to do 
Serious injury. ‘The past season, however, has been an excep- 
tion in Western New York with at least three species, two of 
which are briefly discussed here. The two species have occurred 
in sufficient numbers to cause apprehension on the part of fruit- 
growers in .the western part of the State. Fortunately they 
do not appear in very large numbers until late summer or fall 
when most of the leaves are mature, thus making less injurious 
the work of the caterpillars. |

This species is probably widely distributed in Western New 
York, but judging from the few references in the literature of
