St. Paul, Minneapolis & Omaha, the Great Western, the St. 
Paul & Duluth, the Northern Pacific, the Minneapolis & St. 
Louis, the Great Northern and the Minneapolis, St. Paul 
& Sault Ste. Marie Railroad Companies also deserve thanks 
for their liberality in furnishing free transportation over

The descriptions of many of the insects given are taken 
from a number of sources, but mainly from the excellent 
works of Saunders, Smith, Comstock, Fernald, Beuten- 
mueller, Forbes and of the Annual Reports of the Division 
of Entomology. Most of the illustrations are old, and 
many were kindly loaned by Dr. L. O. Howard, Chief of the 
Entomological Division of the Department of Agriculture. 
The Art Engraving Co., of St. Paul, prepared some of the 
illustrations for the printer, and deserves credit for its good 
work.
