THE MAPLE-TREE BARK-LOUSE. 
BY EMILY A. SMITH. 
HE fruit and ornamental trees grown throughout the country 
are affected more or less by insects belonging to the Coc- 
cide family, or as they are commonly known, bark-lice. The elm 
and maple are among the number, the former infested with a 
Mytilaspis and the latter with Leca@nium acericorticis Fitch. 
The first account we find of this insect is from Dr. Asa Fitch, 
of Salem, New York, in the Horticultural report of that State, in 
1859, page 776. From that time nothing further was written un-

Lecanium acericola in 
the American Ento- 
mologist, vol. 1, page 
14, since which time 
it has been consider- j

name, but as Dr. Fitch

species, I would desire 
re-establishing the first 
name, Lecanium aceri- 
corticis of Fitch.
