western part of the city, where the trees are somewhat abundant, 
was badly injured by the insect, and it was in this section of the 
city where the moths were most numerous. It is probable that there 
were comparatively few extensive flights. The causes for this ex- 
cessive abundance are probably to be found in the scarcity of bird 
life, in the temporary reduction of native parasites and possibly in 
part to unusually favorable climatic conditions. 
_ The extensive defoliations by this species, recorded in our report 
for last year,’ have been continued and large areas in the Catskills 
have suffered severely. Reports of injury in the towns of Harden- 
burg, Shandaken and Ladleton, Ulster co., indicated defoliation of 
extensive tracts of beech. There is also a record of severe injury 
by this pest from DeBruce, Sullivan co. This species was like-

Woodruff reporting that the beeches on the John Brown tract num- 
ber 2, ranges 12 and 13, lots 3 to 8 were defoliated, the stripped 
area being about 3 miles long and having a width of % mile at 
one end and 1 mile at the other. The caterpillars fed at first 
upon young beeches, then stripped the older beeches, practically 
skeletonizing the foliage, and then turned to birches and maples, 
eating holes in the foliage of the latter. The lower limbs of the 
trees on the defoliated area bore numerous empty pupal cases in 
September, and irregular egg masses occurred in abundance upon 
the bark of beech, birch and maple. The eggs of this species are 
deposited at an oblique angle to the supporting surface, are about 
I mm in length, barrel-shaped and light brown, with a conspicu- 
ous dark salmon ring at the extremity. They occur in irregular
