RECAPITULATION, 
For the purpose of summarizing my observations respecting the 
relations of the tarnished plant bug to this strawberry injury, I have 
prepared the following table, dividing the fields in which actual 
counts were made into three groups, according to the amount of 
“buttoning” apparent, and giving the total results of the examinations. 
under each.

The fields covered by this table, nineteen in number, situated at. 
Anna, Villa Ridge, and Centralia, relate to so many kinds of 
plants, and to so great a variety of soil, circumstance and situation, 
that we may reasonably assume that all accidental differences cancel 
each other, and that the differences shown by the general averages 
exhibit only such results as are fairly attributable to the work of 
the insects. 
In the first group of eight fields, where the berries were injured. 
little or none, including Crescents and Wilsons, two hundred and 
ninety-five sweeps were made, capturing one hnndred and twenty of 
the insects, or forty-one to the hundred strokes of the net. In the 
second group, where the berries were injured, but not seriously, 
comprising three fields of Wilsons and one of Downings, one hundred 
and fifty sweeps gave one hundred and twenty-seven of the insects, 
being eighty-five to the hundred. 
In the last group of seven badly injured examples, including 
Downings, Sharpless, Crescents, Wilsons, and No. 2, two hundred 
and seventy sweeps yielded three hundred and eighty-three insects, 
amounting to one hundred and forty-two to the hundred sweeps. 
The totals of this table give seven hundred and fifty net strokes, | 
and the entire yield was six hundred and thirty bugs, an average 
of eighty-eight to the hundred strokes; we have, therefore, in the 
third group about three and a half times as many plant bugs to 
the hundred as in the first, while the average of those moderately 
injured is almost the same as the general average of the three. 
groups taken together.
