Mr. E. B. Soutliwick, Entomologist to the New York Park Com- 
missioners, says that this is the most troublesome of all the insects 
infesting the New York City parks. Wagon-loads of twigs and 
branches are trimmed off in Central Park annually, and the insect 
seems now to have been somewhat checked. The openings to the 
burrows made by the larva: are easily seen by the trained eye, and 
where they are in the trunks of valuable trees or shrubs, or in 
branches that cannot be easily spared, a few drops of Bisulfide of 
Carbon are forced into the burrow by means of an ordinary cil can 
holding half a pint, such as is used by mechanics, and a little dab of 
putty closes the opening. The vapor of the Bisulfide will peuetralc 
the full length of the tunnel, and will kill the larva wherever it may 
be in it, without injury to the tree.
