 be at least five inches deep. The introduction of a fungus 

 which was fatal to the bug was tried extensively but without 

 success sufficient to warrant its recommendation as a reliable 

 measure of control.

squash bug is a very familiar species, a large dark colored 

 insect about three-fourths of an inch long. It hibernates 

 in adult form secreted around buildings or under debris on 

 the surface of the ground and in early summer deposits eggs 

 on squash or melon vines. The nymphs puncture the leaves, 

 and their attack upon the plant often results in a complete 

 withering, so that if the insect is numerous the crop may be 

 seriously affected. The eggs are small glistening objects 

 attached in loose clusters upon the under side of the leaf.
