RECAPITULATION. 
For tile purpose of summarizing my observations respecting the J 
relations of the tarnished plant bug to this strawberry injury, 
nrpnared the following table, dividing the fields m which actual | 
counts were made into three groups, according to the amount o| I 
“buttoning” apparent, and giving the total results of the examination^ I 
under each.

The fields covered by this table, nineteen in number, situated at 
Anna! Villa Ridge, aid Centralia, relate to so many km I 
plants, and to so great a variety of’soil, circumstance and situation;, 
that we may reasonably assume that all accidental differences cance 
each o 6 th“t y and that the differences, shown by the general averjgj!, 
exhibit only such results as are fairly attributable to the work || 
msects 
In the first group of eight fields, where the berries were injure, 
little or none including Crescents and Wilsons, two hundred an. 
ninety-five sweeps were made, capturing one hundred and twenty C 
the insects, or forty-one to the hundred strokes ofthe jk lu™ 
second group where the berries were injured, but not senousij 
comprising three fields of Wilsons and one of Downmgs one huudre, 
and fifty sweeps gave one hundred and twenty-seven of the mse 
being eighty-five to the hundred. _ ■ 
In the last group of seven badly injured examples, 
Downings, Sharpless, Crescents, Wilsons, and Iso. 2, two hundre 
and seventy sweeps yielded three hundred and eighty-three insect 
amounting ^to one hundred and forty-two to the hundred sweeps 
The totals of this table give seven hundred and fifty net stroke 
and the entire yield was six hundred and thirty bugs, an ave 
of eighty-eight to the hundred strokes ; we have, therefore, 1 
third group about three and a half times as many plant bug 
the hundred as in the first, while the average of those moderate 
injured is almost the same as the general average ot the tor 
groups taken together.
