May 7. 
Massachusetts, A, I, Bourne (May 23); Eound hatching in Amherst on May 
Observations in Plymouth County showed first larvae appearing about May 1, 
Along roadsides webs were beginning to be quite conspicuous but, although 
numerous, apparently not quite so abundant as last year or the year before. 
New York, E, P. Eelt (May 23): Somewhat common in New York State west to 
Syracuse, 
R. E, Horsey (May 23): Although a considerable number of nests are to be 
seen, especially along neglected fence rows of wild cherry and apple, there 
are not as many nests at Rochester as in the last 2 years. Observed on 
Japanese quince, crab apple, and cherry. 
New Jersey, E, A, Soraci (May 5 ) '• Very abundant in spots in New Jersey, south 
of a line from Phillipsburg to Elizabeth. Practically no injury in the * 
northern part of the State, Hatching began about April IS in the Trenton

Pennsylvania. C. W, Collins (May 22): Present in considerable numbers on wild 
cherry in one or two localized areas in the northern part of Bucks County 
the first week of May, 
Virginia, A, M. Woodside (May 22): Most of the wild cherry trees in the vicinity 
of Danville defoliated by May 5* Much less common in the Shenandoah Valley,

Wisconsin, H, J, MacAloney (May l6): Common on pin cherry ( Prunus pennsylvanicum ) 
along fence rows in eastern W is cons in. Near Milwaukee tents and caterpillars 
larger than at the Menominee Indian Reservation, : 4o miles north. This is due 
to the more advanced stage of foliation,' 
Correction: The apple tree tent caterpillar reported by S. E. Bailey in Insect 
Pest Survey Bulletin, May .1,1939, page 89 , is M. calif ornica Pack., instead of 
M. americana E. • ■ ■ ■
