18th REPORT OF THE STATE ENTOMOLOGIST 



1902 



To the Regents of the University of the State of New York 



I have the honor of presenting herewith my report on the 

 injurious and other insects in the State of New York for the year 

 ending Oct. 15, 1902. 



General entomologic features. The season of 1902 was com- 

 paratively poor for the development of many insects, and as a 

 consequence relatively few species destructive to staple crops 

 were brought to notice. The elm leaf beetle, Galerucella 

 luteola Miill., has continued its ravages in the Hudson river 

 raliey, is gradually extending its range, and is worthy of particu- 

 lar mention because of its having become established in force 

 at Schenectady and Saratoga Springs. The white marked 

 tussock moth, Notolophus leucostigma Abb. & Sm., is 

 a well known pest of city shade trees, and serious depredations 

 by it have been recqrded from time to time. Thousands of horse 

 chestnuts in the vicinity of Buffalo were practically defoliated 

 by this insect during the past season, and it is not improbable 

 that the same would have been true of other cities in the western 

 part of the State had it not been for persistent efforts to check 

 the insect in earlier years. The fall webworm, Hyphantria 

 t e X t o r Harris, is a common pest which is generally destructive 

 to many trees. It was unusually abundant and injurious in the 

 douthern part of the vState, particularly in Orange county, and 

 also to a lesser extent in some of the western counties. The 

 black banded Lecanium, Lecanium nigrofasciatum
