The investigation work of this office during the past two 
years has been very largely directed. to the study of the in- 
sects found on sugar beets in Illinois and to those infesting 
trees, ornamental shrubs, and the other street, park, and gar-— 
den vegetation of our cities and towns. Our study of the beet 
insects has been presented in a bulletin of the Agricultural 
Experiment Station under the form of a monographic account 
of the economic entomology of the sugar beet for the whole 
United States.
