 The difliculty met with in controlling flea-beetles on potatoes by means of in- 

 secticides led the author to construct the trap here described. This consists of 

 a box the inside of which is covered with a thin coat of tree tanglefoot. As 

 the vines pass through the box from one end to the other the flea-beetles leave 

 them and are caught by the tanglefoot. 



Counts made of the number of insects caught by this trap showed flea- 

 beetles to the number of 1,357 from one-twentieth of an acre, or at the rate of 

 over 25,000 per acre, and the apple-leaf hopper at the rate of 40,000 per acre.
