ARTICLE X.—The European Corn-borer and some Similar Native 
Insects. By Westey P. Fiint anp JoHN R. Mattocu. 
The recent discovery in the eastern part of this country of the 
European corn-borer (Pyrausta nubilalis Hubner) and the possibility of 
its spread westward, has caused much alarm among farmers through- 
out the corn belt. The present publication is intended to give a few of 
the more important facts concerning this insect and some of the closely 
related native borers, and to supply a means of distinguishing them.

DiscoVERY OF THE CORN-BORER AND AREA INFESTED 
This borer was first discovered in this country in a field of corn 
near Boston, Mass., during the summer of 1917. It had probably been 
imported from Europe: in shipments of broom-corn some eight or ten 
years before. In January of 1919 it was found near Schenectady, N. Y., 
and late in the summer of 1919 in some of the lake counties in western 
New York.
