Miss Mary E. Murtfeldt reports upon the insects of the season in 

 eastern Missouri, and also gives the results of experiments which she 

 has made with certain insecticides submitted to her from this office for 

 trial. She also presents descriptions of four Microlepidoptera, which 

 are new in the role of feeders upon Apple. 



Prof. Herbert Osborn reports upon the insects injurious to forage- 

 crops, meadows, and pastures in his State. His report last year was 

 mainly taken up with the consideration of the Leaf-Hoppers, to which 

 he gives some further consideration this year, adding some notes on 

 locusts and crickets. He presents also a series of miscellaneous obser- 

 vations. 



Mr. F. M. Webster devotes his report mainly to the Hessian Fly, dis- 

 cussing the number and development of broods, the effect of the larvae 

 upon plants, the effect of the weather on the development of the fall 

 brood, and preventive measures. He also gives some notes upon three 

 of the species of Plant-lice, found commonly upon wheat. 



In presenting this bulletin for publication, I desire to thank these 

 agents for the care with which they have followed out instructions and 

 for the intelligent manner in which they have conducted these investi- 

 gations.
