 trunks and limbs. Sometimes these are open, and in early summer 

 large quantities of borings are expelled from the inhabited gal- 

 leries, and frequently occur in considerable piles about the base of 

 the trees. It is impossible to attempt to control this insect on other 

 than valuable shade or park trees. In such situations, digging out

Lake. Porter, Marion and Vigo coun- 

 ties, frequent; probably throughout the 

 State. May 31-July 16. This beetle, 

 known as the "poplar borer," is our largest 

 member of Saperda. It breeds in cotton- 

 wood, quaking ash, lombardy poplar and 

 other members of Populus, to which it often 

 does great damage. Three years are prob- 

 ably required to complete its life changes.
