The Army-worm also appeared in some sections in considerable 

 numbers, injuring chiefly oats and meadows. Mr. Coquillett, who 

 was in the section visited by them, devoted considerable attention 

 to the study of their habits and life-history, in order, if possible, to 

 settle some hitherto disputed points in reference thereto. The result 

 of his observations has to a certain extent modified my opinion on 

 one point, to-wit : the number of broods in that northern section. 



It was my intention to have devoted a somewhat lengthy chapter 

 to the general subject of Remedies, but the desire to lessen the size 

 of the report this year has induced me to withhold it, and to devote 

 the space allowed to the papers of those who have assisted me in 

 my Entomological work the past season. Hence the report will con- 

 sist, this year, of papers prepared by Mr. D. W. Coquillett and 

 Prof. G. H. French. 



I take pleasure also in thanking Mr. S. D. Fisher, your Secre- 

 tary, and Mr. C. F. Mills, Assistant Secretary, for many favors, 

 and especially for complying so readily and promptly with my 

 numerous requests to send reports to parties requesting them. I 

 am also under obligations to W. R. Ackerman, Esq., President of 

 the Illinois Central Railroad, for an annual pass over the roads of 

 this company.
