each wing cover. It usually follows Saperda attack in much the same way as does 

 Magdalis. 



Distribution. The elm borer has been recorded from the following localities : 

 Provinces of Ontario and Quebec and from Massachusetts, Rhode Island, New York, 

 New Jersey, Kentucky, Illinois and Michigan. It probably occurs in a number of 

 other states. 



Remedies. Badly infested trees should be cut and burned before the 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 process was carried out on a lot of 1500 elms 

 at Buffalo, N. Y., by Mr M. F. Adams, who reports that the trees were benefited in 

 a most gratifying 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 one pint of crude car- 

 bolic acid, or one-half pint of the refined, and allow it to set over night. The next 

 day add eight gallons 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.

The elms of New York state are unfortunate in suffering from the attacks of two 

 imported insects. The elm bark louse has proved itself a worthy second of its 

 predecessor, the elm leaf beetle, and though it may not of itself be quite so injur- 

 ious as this pernicious leaf feeder, still its constant sapping of elms already weak-
