Mull.) was present this year in enormous numbers in the village of 

 Saratoga Springs, and would have caused serious injury had it not 

 been for the thorough and systematic spraying conducted by village 

 authorities. This species has also been reported as being present in 

 very large numbers at Schuyler ville, only a short distance from Sara- 

 toga Springs. The depredations of the white-marked tussock moth 

 (Xotolophus [Hemerocampa] leucostigma Abb. & Sm.) have not been 

 so excessive as usual, though the pest was generally present in the 

 city of Buffalo and partially defoliated thousands of trees. 



Mr. Felt remarked, after reading his paper, that a bulletin concern- 

 ing the grape root- worm was now in the hands of the printer, and 

 would be distributed at an early date. He had found that where 

 poison was applied to foliage which made a rapid growth, as is the 

 case with grape vines in the spring, that it was not effective in hold- 

 ing this insect in check. 



Mr. Gillette stated that during the past year apple and cherry trees 

 in Colorado had been badly infested with aphides. He had found 

 from observation, however, that many of the eggs which were deposited 

 in the fall failed to hatch during the following spring. He estimated 

 that not one in 1,000 of the eggs laid in the fall of 1902 hatched last 

 spring. In spite of this fact there was an abundance of plant-lice 

 present in June. 



Mr. Cooley had observed the same fact in Montana, and remarked 

 that man}' growers were inclined to give up apple culture because of 

 the serious damage to } 7 oung orchards caused by the apple aphis. 

 He had observed that a lad} T bird (Hippodamia 5-signata) was very 

 abundant and destroyed many of the lice. 



At this point two papers sent by Mr. Slingerland were read by the 

 secretary. They were entitled "Some Serious Insect Depredations 

 in New York in 1903" and "Notes and New Facts about some New 

 York Grape Pests." 



SOME SERIOUS INSECT DEPREDATIONS IN NEW YORK IN 1903. 



By M. V. Slingerland, Ithaca, N. Y. 



The year 1903 may be recorded in the entomological annals of New 

 York as one noted for an excessive and unprecedented development 

 of plant-lice and the pear psjdla, which were generally destructive 

 throughout the State. 



PLANT-LICE. 



The foliage of shade trees, especially maple, el'in, cut-leaved birch, 

 and purple beech, swarmed with plant-lice in many localities. Young- 

 fruit trees — apples, quinces, plums, pears, and cherries — in nurseries
