New York Agricultural Experiment Station. 577 



United States. In Bulletin 83, Cornell Agricultural Experiment 

 Station, page 685, Mr, M. V. Slingerland states that the scale may- 

 be identical with a species observed in Yermont in 1886 and also 

 with a Lecanium scale found on plum at Queenstown, Canada, by 

 Mr. James Fletcher. 



In Bulletin 32 of the United States Department of Agriculture, 

 Division of Entomology, pages 41-44, Miss M. E. Murtfeldt, of 

 Kirkwood, Mo., records her observations upon the life history and 

 habits of a Lecanium scale, found upon both peach and plum trees, 

 which resembles the New York species in many respects. 



In the annual report of the New Jersey Agricultural Experiment 

 Station for 1894, page 502, Prof. J. B. Smith mentions a Lecanium 

 scale, under the name L. cerasifex, which he considers identical 

 with the New York species, and states that he has found it in small 

 numbers " at several points " in New Jersey. 



The writer has had his attention called to a Lecanium scale which 

 was quite abundant on plum trees in Lapeer county, Michigan, 

 during the season of 1894. In one plum orchard in particular the 

 scales were very abundant, and it is reported that several trees were 

 badly injured by them. This scale has the appearance of being the 

 same species as the New York Lecanium, although we have not yet 

 examined it in its different stages with sufficient care to be positive. 



The scale has also been observed on plum trees by the writer at 

 Hector, Lodi, Geneva, Rochester, Syracuse, and Castleton Corners, 

 Staten Island. In all of these places, with the exception of Syra- 

 cuse and Castleton Corners, the scales were present in sufficient 

 numbers to cause serious injury to trees and fruit. 



As before mentioned, specimens of the scale have also been sent 

 to the Station from various other localities in the western part of 

 the State, 



The above indicates that the scale has a wide range in this State, 

 and that it may be well known in widely distant localities in the 

 United States. Thus far, however, it seems to be doing the greatest 

 damage in western New York. 



History in New York. 



From reports received from fruit growers it appears that the scale 

 is not a new comer in western New York. One fruit grower states 

 that he has occasionally seen the scale in his plum orchard for 

 twenty years past.
