be much lighter this spring than- a yecx ago. During February an 
excess of rainfall and frequent cold spells have held back the early 
growth of cane, but sprouting of cane in the fields has been unusu-

MISCELLANEOUS FEEDERS 
MITE-MARKED TUSSOCK MOTH ( Hemerocampa la uco sti gma 3. L A J 
Ohio E. W. Mendenliall (February 16): The egg masses are very plentiful 
on many of the shade trees and in crevices of buildings and fences. 
At Columbus and throughout southwestern Ohio the egg masses of the 
tussock moth are ve ry . numerous . 
BAGWORM ( Thyridopteryx ephemeraeformi-s Haw. ) 
Ohio E. V. r . Mendenhall (February 16); The winter cases of the bagworm are 
very numerous on shade trees and shrubs in and' about Columbus and 
southwestern Ohio. Some of the public schools have a campaign to 
collect the bags. (February 25): The bagworm cocoons are very abun- 
dant on nearly all shade trees and many kinds of shrubbery in and 
about Dayton, This is a real pest in Dayton and Cincinnati „ They 
are very destructive to many kinds of trees and especially to the 
conifers . 
Missouri L. Haseman (February 24): Through southern Missouri and through 
central Missouri a real infestation of this pest developed last 
year but recent inspections of the overwintering bags show that a 
heavy infestation of parasites is present and breeding experiments 
are 'under way to determine what species of parasites are present. 
SPRING CANKER V/OEJ i (Paleacrita vernata Peck) 
Kansas H. B. Hunger ford (February 15): Considerable emergence of both 
sexes was in progress on February 6. Males have been appearing on 
the tree bands since about the middle of January. 
JA W. McColloch (February 25): Canker worms are on the increase, 
and the possibilities are that there will be some damage to shade 
trees and fruit trees this year. Moths have been out at various 
times from early in January. 
OYSTER-SHELL SCALE (Lepidosaphes ulm i L. ) 
Ohio E. W. Mendenhall (February 25): The oyster-shell scale is quite bad 
in Dayton and vicinity on soft maple, Carolina poplar trees, and 
lilac bushes and, as far as I have discovered, it is bad on poplar, 
ash, soft maple, lilac bushes, and some others, all through the south- 
western part of the State.
