THE CANADIAN ENTOMOLOGIST. 141 



(35) Lecaniuin Kingii, CV.\\.; 189S-1898. N. 



Quite frequently found on high-bush blueberry, Vciccinium corym- 

 bosum, L.; at Lawrence, Mass. 



(36) LecaniuJti tarsale. Sign.; 1873, var. 1898. N. 



On dogwood, Cornus alteniifolia, at Lawrence, Methuen, and 

 Andover, Mass. Generally found on the trunk of the trees, seldom on 

 the limbs. It is parasitized by Blastothrix longipetmis, How, 



(37) Lecanium Fletcheri, Ckll.; 1 893-1 898. N. 



At Lawrence, Mass., on Arbor vitce. It is found at New York by 

 Mr. Pettit and was described from Ottawa, Canada. Found there by 

 Dr. Fletcher on cedar. 



(38) Lecanium nigrofasciatum^Ytxg.; 1898-1897. N. 



Found at Methuen, Boston, Springfield, Holyoke, and Deerfield, 

 Mass., on Acer rubrum and Acer saccharinuin ; also found at Washing- 

 ton, D. C; Maryland, Georgia, Tennessee, Pennsylvania, New Jersey, 

 New York, Delaware, Ohio, Missouri, Illinois, and Florida. It is para- 

 sitized by Aphycus flaviceps. How. Dr. Howard, who has had all the 

 parasites reared by me for study, reports to me (in li-tt.) that these 

 specimens were badly shrivelled, so he could not make the determination 

 with absolute certainty, and that the parasite has been previously reared 

 from Lecankim by Prof W. G. Johnson at Champaign, 111. Dr. 

 Dimmock informs me that some of the trees were very badly infested by 

 this scale, which has been nearly exterminated at Springfield by a parasite. 

 The food plants in other localities are olive, vaccinmni, plum, apple, peach, 

 birch, maple, Buraelia and LiiuJera benzoin. It also occurs in Western 

 Ontario, Canada, on maple. 



(39) Lecanium pa/lidior, Ckll. and King; 1S99-1898. N. 



On a young native white cedar, Cliamcecyparis iJiyoides, at Methuen, 

 Mass. 



(40) Lecanium caryce, Fkch ; 1856-1898. N. 



At Lawrence and Methuen, Mass.; on pignut hickory and wild red 

 cherry. The writer has endeavored to find the original type of Fitch's 

 species. At present it looks as though there are none to be found. 

 Prof. Cockerell will in the near future redescribe the species, as it is very 

 much confused with many others, owing to the very short and incomplete 

 description by Fitch. The unrecognized Lecanium platycerii described 

 by Dr. Packard in 1869, said to be common in greenhouses in 

 Massachusetts, was probably Lecatiium coffece, Walk.
