remedies. 
The standard remedies for the devastations of plant-lice are pyre- 
thrum and the kerosene emulsion, the first of which may be applied 
at anv time and the second whenever the plants aie not bearing 
rineninefruit If the plant-lice should occur on the leaves m con- 
siderabfe numbers after the fruit is picked, it would doubtless be 
easy to control them by mowing and burning the field as for the 
Tn case the Aphis which I have described should be found upon 
the crowns in fall, it would be decidedly imprudent to use plants 
from tMs fi“d for setting new fields the following spring, as many 
ofThe crowns would be almost certain to contain the eggs I think 
that it is entirely probable, however, that such plants could be freed 
from” either the eggs or the lice by dipping them in water upon 
which was a thin film of kerosene, care being taken, ot course, that 
kerosene enough was not used to injure the plants. 
The False Chinch-Bug.

This insect is one of the many causes of the circular ®P§ 
with which the leaves of strawberries become discolored during tb 
summer, and it occasionally becomes abundant enougb to locoD 
siderable mischief. It is commonest in autumn m p fields; which u 
overgrown with purslane, upon which it seems to feed by p^ieterence 
hut of course under these circumstances, it is little injurious to tm 
strawberry. I have found it especially abundant m strawberry field 
at Centralia; and it is probable that the following item from t | 
Western Rural for 1870, by a fruit grower of Centralia, refeis 
this species: 
“A new insect, to us here, lias appeared on our strawberries b 
the first time the past season, damaging the crop very muob._ 
resembles somewhat the chinch-bug, so destructive to our wheat ar 
corn and judging from the peculiar odor they emit on being masne 
I should think them very nearly related. Some claim that they a 
of a different species altogether. Whether this be so or not the 
interested in the cultivation of the strawberry are anxiously look 
forward to another season to see if they are to continue th 
depredations.” 
It has also been known to injure seriously the tohage o f 7^ 
grapes, of potatoes, turnips, beets, cabbages, etc. T e , 
broods maturing is not known. In November, the adults, m g 
with a few pupae, may be found abundant among hibernating ms
