136 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



Should the insect become very abundant, it may be destroyed by the 

 methods used for the control of the Colorado potato-beetle, viz.: The 

 application of Paris green or London purple. 



As most of the many enemies which have acquired the habit of prey- 

 ing upon the Colorado beetle during the several years of its excessive 

 prevalence will, in all probability, as readily feed upon the three-lined 

 leaf-beetle, we need not apprehend, for some time to come, serious 

 ravages from it in our potato fields.
