by the first brood larave was rather prominent and on June 24 I visited 
Greenwich and Stamford, and crossed the State line into Port Chester, 
N. Y. Some apple trees in Greenwich, but many more in Port Chester, 
had been skeletonized, and the foliage was entirely brown. This had 
been done by the first generation larvae which had matured, pupated, 
and many adults had emerged by June 24. When disturbed, the little 
purplish brown moths flew out of these trees in swarms, and they were 
common, resting upon the daisies and other flowers about the field. 
During the season of 1921, this insect and its work was sent to the 
Station from many different points within the State, and Station ento¬ 
mologists observed it at other places, so that by the end of the season we 
had records of it from all counties except Windham County in the north¬ 
east corner of the State. This seemingly rapid spread was noted in the 
Station Report for the year. 5 
During 1922, the insect was very abundant about New Haven, 
particularly late in the season. Nearly all unsprayed apple trees were 
brown. The writer observed this condition in New Haven, Orange, 
Woodbridge, Milford, Hamden, Cheshire and along the automobile 
thoroughfare between New Haven and Springfield. Many inquiries 
about it were received at the Station and many specimens were sub¬ 
mitted for identification. One of the Assistant Entomologists ob¬ 
served the insect in Windham County, so that now we know that it 
occurs all over the State. 
In New York State, according to Dr. Felt, a rather serious infestation 
of this insect was discovered the past summer in the southern part of 
Albany County, near Albany, and at present the insect occupies a 
strip along the Hudson River valley but not extending more than 
four or five miles on either side from the River. It is believed to be 
present in northern New Jersey but no very definite records are at 
hand. 
During August the writer examined a number of apple trees and 
hawthorn bushes in the vicinity of Pittsfield, Mass., without finding any 
traces of the insect. Dr. B. A. Porter, however, later observed it at 
Huntington and Amherst, Mass. At Amherst, late in the fall, the adults 
were quite abundant, and as the infested trees observed would hardly 
produce them in such numbers, it has been suggested that they migrated 
northward from Connecticut, where they were very abundant in Septem¬ 
ber, October and November; even a few have been observed since
