’8e of this fly kept in confinement, pupated during the first 
: August, and the flies emerged between the fifteenth and 
-fifth of September. During this period the larvae were ob- 
j among the lice in the fields, a fact which indicates several 
during the summer. The only dies obtained were accident- 
stroyed, and their species can not therefore, be definitely de¬ 
ed. The larvae creep like leeches, and when they have seized 
t louse, raise the anterior part of their bodies so as to pre- 
le struggles of the prey freeing it from their grasp. A Euro- 
pecies is said to devour as many as one hundred plant lice 
hour. I have watched our species on several occasions, 
en when hungry they did not finish one louse in less than 
nutes, and three or four lice at one time seemed to satisfy 
Generally but one or two larvae occur in a colony of lice. 
Smaller Two-Spotted Lady Bug ( Hyperaspis signata, Oliv.)— 
ady bug has a reputation as a destroyer of the destructive 
jmse of the maple trees. It occasionally occurs also among 
:*ds of corn plant lice in the com fields. 
Plain Lady Bug ( Cycloneda sanguined, Linn.)—The adult of 
:ly bug is also found among colonies of lice. It is less com- 
5 a rule than the following species, but in some fields in the 
Dart of the State which we visited, it was the more abundant 
two. 
jj Spotted Lady Bug ( Megilla maculata, DeG.)—This lady bug is 
[jin in all its stages upon corn and destroys great numbers of 
n the autumn and winter great numbers of the adults, some- 
i housands in a heap, may be found under boards at the edges 
fcorn fields. 
other lady bugs, Hippoclamia glacialis and Coccinella 9-notata 
>een observed in the fields but neither occur in sufficient 
■s to be of any great service. 
Lace-wunged Fly ( Chrysopa sp.)—The larva of one or more 
of these Hies are frequently seen devouring the aphides, and 
nally are locally abundant in the fields. 
Artificial Piemedies. 
•tificial remedies but little can be said. The corn fields are 
3 that an application of any of the insecticides which can be 
uccessfully for smaller crops would be impracticable. The 
bs and predaceous insects may be depended upon to prevent 
neral increase in the numbers, and where local outbreaks 
more than one season’s serious damage can probably be 
by burning off old fields in the fall as soon as the corn is 
and to some extent also by planting on ground which has 
n in com. For garden corn the use of a solution of kerosene 
; >n thrown upon the corn from a garden engine carried on a 
uld be sufficient to destroy the lice.
