THURSDAY AFTERNOON. 
The Society was called to order by the president, Grimes, at 2 
o’clock: 
Mr. Fuller proposed to report final resolutions, but it was voted 
to proceed with the regular order of business, which was 
MR. MENDENHALL’S PAPER. 
Mr Mendenhall was called upon and read his paper, which was 
as follows: 
PLANT-LICE. 
In former papers read before this Society I have given accounts of most 
of the big bugs that plague the farmer and gardener, and to-day I propose 
to call your attention to some of their smaller, but by no means less import- 
ant relations. Among these minute pests are the well known plant-lice, 
bark-lice, thrips, and tingis. All of these insects belong in the order of 
true bugs (Hemiptera), and subsist exclusively on the sap of plants, which 
they obtain by puncturing the leaves, buds, and twigs with their tubular, 
needle-like beaks. When they have exhausted the sap and destroyed the 
vitality in one leaf or other part of the plant, they withdraw their beaks 
and seek fresh pasturage; proceeding in this way until a large part of the 
infested plant is blighted and either killed outright or very much retarded 
in its growth. 
As it would be impossible to treat of all these insects ina single paper, we 
will confine our attention, for the present, to a few of the most destructive 
species of plant-lice (Aphididae). 
The latter are found wherever vegetation fiourishes, and do great harm in 
a climate like ours, where the annual growing season is short and the plant, 
whether tree, shrub, vine, or herb, requires the healthy action of all its 
organs to perfect its flowers and fruit.
