86 HATCH EXPERIMENT STATION. [Jan. 



REPOET OF THE E:N^T0M0L0GISTS. 



C. H. FERNALD, H. T. FERNALD- 



The work of the entomological division of the experiment 

 station during the past year has followed the lines of pre- 

 vious reports. The amount of correspondence has been 

 much larger than ever before, being due in a great measure 

 to the appearance of the elm-leaf beetle in the eastern por- 

 tion of the State in such numbers as to do great damage, 

 and also as an indirect result of the appointment of tree 

 wardens. These officials in the course of their duties have 

 watched the trees and the insects upon them closely, and 

 have frequently communicated with the station concerning 

 their observations. Correspondence of this kind has in- 

 creased nearly ten per cent, over that of former years, which 

 is of itself a testimonial of the value and success of the tree 

 warden law. 



The entire edition of a former publication of the station 

 upon the elm-leaf beetle having become exhausted, a new 

 bulletin on this insect was prepared and published during 

 the summer. This was the only paper from the entomolog- 

 ical division published by the station, but others were pre- 

 pared by the division and published during the year by the 

 secretary of the Board of Agriculture of Massachusetts. The 

 most important of these was a paper on " Three common 

 orchard scales," with figures and half-tones, published in the 

 Crop Report for May, 1901, and which has been in much 

 demand. 



The station was represented at the meeting of the Official 

 Horticultural Inspectors of the United States, held at Wash- 

 ington, Nov. 11-13, 1901. At this meeting much uniform- 

 ity of practice among the nursery inspectors of the different 

 States was established and many results of value obtained.
