Lecanium is found in Western Ontario, on Acer saccharinum. Just 

 recently Dr. Fletcher sent me specimens on white maple {A. dasycarpum) 

 from St. Catharines, Ontario. Although this is called the Peach Lecanium, 

 it is by no means confined to peach trees, as it is found on various species 

 of maple, plum, apple, Crataegus, sycamore, Brnvielia, linden, olive 

 and Vaccinium.

Lecanium cerasifex, Fitch, 1856. (Native.) Said to have been 

 found on plum at Queenston, Ontario, in 1894. and since that in many 

 places in the fruit district extending from Niagara to Burlington, Ont.

Lecanium pruinosum, Coql., 1891. (Native ) This was found on 

 peach at Niagara, Ontario. Received from Prof. Cockerell last year, sent 

 to him by Dr. Fletcher. 



Lecanium IVebsteri, Ckll. and King, 1901. (Native.) On black 

 and red currant in Nova Scotia and at Ottawa, Canada. The species 

 was for a long time supposed to be Fitch's L. ribis. It seems to be quite 

 a general feeder, as will be seen when reference is made to the literature. 



Bib. — Can. Ent., xxxiii. (1901), 108. 



Lecanium carya, Fitch, 1856. (Native.) This was found sparingly 

 on peach at Niagara, Ontario, by Dr. Fletcher in 1898, and since that 

 has been occasionally found by Mr. George E. Fisher on the same tree ; 

 but never in abundance. It is the largest species of the subgenus 

 Eulecaniutn found in North America. All that is known of the species 

 will be found in the literature cited below.

Lecanium. Species probably new; not sufficient for study; was 

 received with the above species ; also found at Niagara, Ontario, on peach. 



Lecanium armeniacum, Craw, 1892. (Native.) The apricot scale 

 was found infesting orchards at Sherbrooke, Quebec, in 1899; it is 

 common in California. 



Bib. — Ann. Rpt. Exp. Farms, 1899, p. 160. 



Lecanium cynosbati, Fitch, 1856. (Native.) Was received from 

 Mr. John Dearness in 1900 ; found at London, Ontario, on honey locust. 

 Dr. Fletcher states that he found this species abundant on honey-locust 

 trees in the streets of Dundas, Ont., in 1898.
