under favorable conditions. A number of eggs 

 are deposited on the side of the kernels. In 

 four to seven ,days they will hatch, and the 

 larva will then burrow into the kernel and 

 begin to feed on the inside of it. In about 

 three weeks it is full gi-own, when it is about 

 one-fifth of an inch long. Then it burrows 

 towards the outer end of the kernel, leaving 

 only a thin cap to cover the cavity. A small 

 white cocoon is then made in the burrow, and 

 the larva in this soon changes to pupa, acid 

 after a short time emerges in the moth form. 



This insect is especially injurious in the 

 South, where stored corn is often seriously 

 damaged, North of Kentucky little injury may 

 be expected from it, as it is a warm climate 

 insect. At the New York State experiment 

 station the writer had considerable experience 

 with it, as it occurred in a collection of corn in 

 the. museum. These insects were brought to 

 the museum in specimen ears shipped from the 

 South and before their ravages could be stopped 

 nearly the entire collection was ruined. 



In the field there is no known method of 

 combating it. To destroy the insect in the 

 seed, place the grain in a comparatively tight 

 room and pour a little bisulphide of carbon in 

 among the corn. This soon changes into a 

 deadly gas and will destroy all insects inhaling 

 it. But to save the seed the operation should
