INSECTS AFFECTING PARK AND WOODLAND TREES 7 1 



beetles have had an opportunity to emerge in the spring, that is before the 

 latter part of May, in the latitude of New York. And in a like manner 

 infested portions of others should be cut away and burned. This latter 

 treatment was given a lot of 1500 elms at Buffalo X. \., by Mr M. V. 

 Adams, who reports that the trees were benefited in a most gratifymg 

 manner. 



Protecting the trees during the period of oviposition with a carbolic 

 acid wash has been frequently recommended but it is of doubtful utility. 

 Where this insect is very abundant and its injuries correspondingly serious, 

 it would do no harm to try the effects of a wash. One of the best may be 

 prepared as follows : thin a gallon of soft soap with an equal amount of hot 

 water and then stir in i pt. of crude carbolic acid, or j4 pt. of the refined, 

 and allow it to set over night. The ncNt day add 8 gal. of soft water and 

 apply to the parts to be protected, which in the case of this insect would be 

 the trunk and base of the lower limbs. The bark should be kept moist 

 with this substance from the latter part of May through to the end of July. 



Removing portions of the bark has also been recommended. The 

 badly infested portion should be cut away and the grubs destroyed and 

 where a few are working in living bark, it might be well to remove the 

 upper layers till the grubs are nearly exposed and then brush over the 

 shaven surface with strong kerosene emulsion or whale oil soap solution, 

 finally covering the wound with a paste formed of a mixture of fresh cow 

 dung and lime or with a coat of cheap, red paint.

Neoclytus erythrocephalus Fabr. 

 A small reddish beetle about H i'^-h long and prettily marked with three yellow, 

 nearly transverse lines on each wing cover, is rather frequently bred from elm, hickory, 

 and some other woods affected by borers.
