DETAILED DISCUSSION OF INJURIES TO THE SEED. 
1. Injuries by ants (Myrmicide), which hollow out the kernel, com- 
monly scattering the meal through the dirt. 
Injuries to corn by ants are of two kinds; one indirect but serious ; 
the other direct, but of little importance because quite rare. The former 
will be treated in connection with insects affecting the root, since it is 
by rearing, transporting, and fostering the root lice of corn that ants 
are most injurious; and the latter is given here in its place as an injury 
_to the seed in the earth. 
Occasionally in searching for the causes of the failure of corn to 
germinate, or to grow thriftily after making its appearance, a kernel 
may be found wholly or partly hollowed out, the mealy interior being 
not devoured, but scattered about in the earth, while the cuticle or outer
