".'. P. Flint (June 19): This insect is being reported from 
several localities in the central part of the State, and is 
apparently increasing generally in Illinois. No serious in- 
jury to trees has been reported, although a number of elms in 
the vicinity of Chicago and Urbana show a rather heavy infes- 
tation. 
M. H. Swenk (May 15-June)15): An additional report of the 
European elm scale was received from Redwillow County (McCook) 
during the first week in June.

caused disfigurement of a number of hickory trees on an es-

LARCH CASS BEAKER ( Coleophor a laricella Hon. ) 
H, 3. Peirson (June 6): A heavy infestation on larch near 
Augusta has been reported, we have not been able to raise 
any parasites. Climatic conditions seem to have a strong 
influence on the abundance of this pest. 
LARCH SAWFLY ( l-Tematus erichsoni Hartig) 
J. A.I.dunro (June 25): June 20 a planting of larch at Man- 
dan, Norton County, was found to be infested with the larvae 
of the larch sawfly. The following day an arsenical spray 
was applied with the result that most of the worms were 
killed. Horticulturists at Mandan told me that they knew of 
no other larch plantings within a radius of 150 miles and 
that they waro Gt a loss as to how the insect became estab- 
lished there. 
"70CLLY LARCH APHID ( Chermes strobilobius Kalt.) 
R. 3. Friend (June 3): This insect is more abundant than 
usual on European larches at i.iddleburv.
