FOREST AND SHADE-TREE INSECTS 
GYPSY MOTH Cgorthetria dispar L. ) 
Maine. J. V. Schaffner, Jr. (July 16): N. Urafton reports defoliation of 
hundreds of acres of woodland in Kennenec, Sagadahoc, and Lincoln 
Counties. The infestation is the heaviest on record for these three 
counties. Defoliation was spotty and local in the northern part of 
York, southern Oxford, Androscoggin, and Cumberland Counties, 
Portland Press Herald (June 29) : Officials of the State depart- 
ment of agriculture report the worst gyptyy moth scourge ever to sweep 
southwestern and central Maine. Occurrence of the moths in devastat- 
ing numbers is reported as far as Kennehec and Knox Counties, and in 
less serioue intensity eastward along the Oastal counties to .Washing- 
ton County. 
Massachusetts. J. V. Schaffner, Jr. (July 6): Thousands of acres of wood- 
land in the eastern part of the State are completely defoliated. The 
defoliation within 25 or J>0 miles of Boston is more extensive than it 
has "been for many years. 
A. I. Bourne (July 23): The defoliation this year was much more 
general and widespread than in any recent year. There are "beginning 
to he many centers of rather serious defoliation just west of the 
Connecticut River. Throughout central and eastern Massachusetts are 
similar large areas of very serious foliage strippings; however, in 
the Cape district, from Buzzard's Bay to Province tov:n, conditions are 
apparently "better than for several years. 
Rhode Island. A. E. Stene (July 23): Prohably the most outstanding note 
regarding insect prevalence during the past month is the increase in 
gypsy moth infestation. We have had large areas heavily infested 
with this insect in the past, "but there were a greater numher of * 
places involved during the past season and the aggregate area where 
defoliation has taken place is quite large. 
Pennsylvania. A. P. Burgess (July 17): The interest of. a former W.P.A. 
worker resulted in the discovery of a larval infestation near the 
Coolbaugh-Paradise Township line in Monroe County. This man, now 
employed "by the Delaware, Lackawanna, & Western Railroad Company, 
observed an egg cluster Of the gypsy moth while working along the 
railroad right-of-way and reported to the field supervisor in charge 
of that district. Numerous larvae have since "been discovered in a 
rather restricted area. Intensive treatments will "bo applied in an 
effort to eradicate the infestation. 
BROWN- TAIL MOTH ( Nygraia phaeorrhoea Donov. ) 
Maine. N. Trafton (July 26): Only a few larvae were seen this season and 
these were scattered through the towns of Bath, Hehron, Raymond,
