REPORT OF STATE ENTOMOLOGIST, 1898 235 



An interesting feature in the latter city was the more extended injury 



sustained by the American elms. In Troy comparatively few of this 



species appear to have suffered much. The same was true of Albany 



two years ago. Last year considerable injury was inflicted and the 



present season much more in spite of the spraying. It should be stated 



that rainy weather just after the larvae hatched marred the efficiency of 



the work seriously. A few of the American elms in Albany have lost 



nearly every leaf and hundreds have been so affected that they present a 



more or less browned appearance. In Watervliet, where American elms 



abound, the ravages have been frightful, including practically all the 

 elms. 



Galerucella cavIcoUis LeC. In his nth report Dr Lintner noticed 

 this insect briefly and gave its earlier history. The species is one 

 that is apparently changing its habits and becoming destructive. Mr 

 Tupper, of Corning, N. Y., submitted examples of this insect and leaves 

 from his cherry-trees, with the statement that they were injuring the trees 

 seriously and might kill them. This is the second record of a recent 

 attack on cherry in New York state by this species. 



Notolophus leucostigma Sm,-Ahb. The larvae of this species were 

 unusually destructive in Albany this season. Not only were a large 

 number ot horse chestnuts defoliated, as frequently occurs from year to 

 year, but many of the maples and lindens were seriously injured. On 

 some trees the caterpillars were so abundant as to cause an unpleasant 

 odor. It appears nearly impossible to secure adequate protection for 

 trees along the streets, unless it is undertaken by the municipal authori- 

 ties. The private individual who inquires what he should do to protect 

 his trees after two-thirds of the foliage is destroyed, usually neglects to 

 take proper precautions to prevent trouble another season. 



The injuries by this species in Buffalo have been so general as to excite 

 considerable attention from the public and have led to the issuing of 

 a special circular by the board of public works, giving directions for 

 controlling the insect. It was also reported as very abundant at Flush- 

 ing, L. I. 



Ravages by tent caterpillars. In early spring a number of reports 

 came to me of the extraordinary abundance and destructiveness of the 

 apple-tree tent caterpillar, Clisiocampa aijiericana Fabr. In many 

 localities the larvae stripped the trees and nearly covered the naked limbs 

 with their webs. Such work was clearly the result of neglect and yet 

 Mr S. D. Willard, of Geneva, who cares for his trees each year, informed 

 me that this insect caused him considerable trouble last spring, notwith- 

 standing his efforts to keep it under control.
