term of years. A recent note’ by Prof. M. V. Slingerland states 
that this species occurs in small numbers at Ithaca N. Y. 
White marked tussock moth, Notolophus leucostigma 
Abb. & Sm. This is one of the well known serious enemies of 
our shade trees in some of the larger cities of the State; and it 
is not unusual to see a number of horse-chestnut trees defoliated 
by the caterpillars. The cities of Albany and Troy have been 
comparatively free from this species in recent years, because in 
all probability, of the active measures employed for the control 
of the elm leaf beetle, which naturally resulted in other insects 
receiving the same treatment when their unusual abundance ren- 
dered it necessary. The work of this insect was exceedingly 
prevalent during the past season in the city of Buffalo, where 
it defoliated thousands of horse-chestnut trees over a considerable 
portion of the city. It was an exception to find one which had 
escaped injury, and the foliage of practically all of the trees was 
destroyed. 
This species occasionally produces two generations a year in 
the vicinity of Albany, a fact which has not been previously 
recorded. The writer’s attention was drawn to a number of the 
caterpillars of this insect on a small, soft mapletree in Albany 
in the early part of September. These were undoubtedly a second 
generation, and occasionally individuals of the same species have 
been met with here and there during the latter part of the sum- 
mer. This is very interesting, since this species is known to 
produce two generations normally in Boston and New York, while 
at Albany and probably some distance south a single brood is the 
rule. 
Fall webworm, Hyphantria textor Harris. This is one 
of the injurious general feeders, which is usually present each — 
year in greater or less numbers in some section of the State. It 
was unusually abundant and destructive in the southern counties, 
particularly in Orange and Rockland, where its nests were very 
conspicuous in many trees. It was also reported as quite abund- 
ant and destructive in some of the western counties, specially in 
Genesee, where it was stated to be more numerous than Mr J. F. 
Rose had even seen before. This species is such a general
