FOREST AND SHADE-TREE INSECTS 
PERIODICAL CICADA ( Magicicada septendecin L.) 
Virginia. W. S. Hough (June 4): A small "brood of the seventeen-year cicada was 
reported from Fre-derick County. 
Pennsylvania. J. L. Kinter (June 11): Immense numbers of the plague in the 
vicinity of Homer City, singing and laying eggs. 
D, C. Washburn (May 28): Reported as appearing nightly in hordes 
near Lutzdale, Alleghany County. 
Ohio. G. T. Greer (June 5) '• Cicada septendecim observed in Wick Park, Youngs- 
town, Mahoning County, on May 27. Since that time they have increased to 
a normal number for any locust year, 
Georgia. Wm. F. Turner (June 1-5): Great numbers of the periodical cicada heard 
singing in the extreme southern part of Pike County. (These belong t o 3rood 
XX of the 13-year race, a small brood recorded 1 from northern Georgia. J.A.H. ) 
Kansas. R. II. 3eamer (May 15 & 28): A few specimens of the form cassinii Pish 
were observed at Leavenworth on May 15r an( i at Lawrence on May 28. ("These 
are possibly retarded specimens of 3rood XIX, but this brood has never been 
recorded from Leavenworth or Lawrence. J.A.H.) 
PALL CANKER WORM ( Alsophila pome t aria Harr.) 
Massachusetts, Connecticut; Rhode Island, and New York. J. V. Schaffner, Jr. j 
(June): Several reports have been received on the abundance of this pest' 
in eastern Massachusetts. The earliest spraying operations carried on by 
cities and towns against the gipsy moth and elm leaf beetle undoubtedly have 
prevented much defoliation by A. pome t aria . In the 31ue Hill section of 
Milton, Mass., from 50 to 100 acres of woodland and many shade trees of elm, 
oak, and ash were reported to be from 50 to 100 percent defoliated on June 6. 
C. E. Hood reported on June ik that many shade,- woodland, and apple trees in 
the vicinity of New Haven and North 3ranford, Conn., are quite badly infested. 
On May 31 many shade trees' and some woodland areas in the vicinity of Crans- 
ton, R. I., were from 25 to 100 percent defoliated. On June k to 6 severe 
infestations were noted on shade trees, particularly elm, in apple orchards, 
oak woodlands, and in wastelands growing up with wild cherry and other de- 
ciduous growths. Woodland stripping is quite prominent in many localities 
as far north as 3edford Township. Many large elm shade trees are completely 
defoliated. In the northern part of this area some of the stripping in the 
oak woodland is due in part to the abundance of Phi gal ia t itea Cram., 
Erannis tiliaria Harr. , and other native species. 
Connecticut. W. E. 3ritton (June 23): This insect has been unusually abundant 
and has defoliated unsprayed orchard and woodland trees in many small areas 
in Pairfield, Middlesex, and New Haven Counties. 
SPRING CANKER WORM' ( Paleacrita vernata Peck) 
New York. H. C. Hallock (June 2): In the vicinity of Locust Valley, 3rookville, 
and Old'Westbury, apple trees are 100 percent defoliated. At Hempstead Lake 
State Park (south of Hempstead) oaks are about 30 percent defoliated, and 
the annoyance caused by the v/orms has greatly reduced the number of people 
using the park.
