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
