New York M. D. Leonard (August 25):' Mrs. 0, J. Spahn reports that a sir all 
tree about 4 feet high at Pleas antville contained hundreds of the 
larvae and the needles were stripped off, a^so that many larger 
pines were heavily infested. (August 20) : A spray of pine 
twigs was received bearing numerous full-grown larvae and several 
pupa cases. 
R. E. Horsey (September): A few larvae were found on white pine, 
September 6, at Highland Park. Except for a Dad outbreak in 
August, 1918, which was promptly controlled by arsenate of lead 
spraying, we have had no trouble with this, a few only being found 
each year since. 
Bureau of Entomology Monthly Letter, No. 113: Dr. K. E. Burke re- 
ports considerable damage to the native forest of Monterey pine at 
Pacific Grove, Calif., by a defoliating sawfly. S. A. Rohwer has 
determined the sawfly as Itycorsia brunnicans Nort . , stating that 
the species has not been reared and that practically nothing is 
known of its habits. Further study by Doctor Burke has yielded 
the eg?-s of the species, the habits of the young larvae, and the 
fact that nicotine dust promises to be more effective in control

H EMLOCK 
FLAT-HEADED HEMLOCK BORER ( Melanophila fulvoguttata Harr.) 
M. D. Leonard (August 25): Bark was reported infested with grub- 
at Upper Saranac, Franklin County, with a statement that many fine 
old hemlocks were found infested upon being felled. 
POPLAR 
TENT CATERPILLAR ( Malacosoroa ainericana Fab.) 
H« B. Pierson (July): The tent caterpillar assumed alarming pro- 
portions in several sections of the State, and it is safe to state 
that probably at least 60,000 acres of poplar and white birch were 
stripped. As several areas were stripped this year, there is a 
danger of large areas being killed, owing to repeated defoliations. 
Tne worst areas are in the vicinity of Stacyville, Eagle Lake, 
Fort Kent, Mt. Chase, Masardis, and Moro Plantation. (October 3): 
One area in which the eggs and pupae were heavily parasitized last 
year proved to oe even more heavily infested this year. Somerset, 
Piscataquis, Penobscot, and Aroostook Counties are reported infested 
by this insect. It is found in greater abundance than in an 
average year.
