some systematist is liable to put the insect into another genus any 

 day. We like the name of ' ' ribbed cocoon-maker of the apple " better 

 than any other we have been able to get, for it is suggestive of that 

 phase of the insect which is usually the first to attract the orchardist's 

 attention. 



THE APPLE-LEAP BLISTER MITE. 



The pear-leaf blister mite is now a well-known pest in many sections 

 of the country, but never before until last summer had we seen or 

 heard of a similar pest in apple leaves. Scattered through central 

 New York there were many apple trees with many of their leaves 

 showing the corky blisters characteristic of these mites. We have 

 not yet made a careful study of the mites to determine if they are the 

 same as the pear species. The blisters in the apple leaves differ 

 slightly from those in pear, but this may be due to the different food- 

 plants. 



CABBAGE AND ONION MAGGOTS. 



Much loss resulted in the large cabbage and onion sections of New 

 York last season from these maggots. Apparently no one made any 

 effort to check the pests. 



GRAPE PESTS. 



The ravages of three grape pests in Chautauqua County have been 

 discussed in another paper in these proceedings. 



THE PLUM CURCULIO. 



Many New York plum and cherry growers have long desired a less 

 laborious method than the " jarring" process for fighting this pest. 

 Poison sprays have been recommended and tested for many years, 

 and some think they succeed in controlling the insect in this way. 

 Last season several growers made thorough tests of arsenate of lead, 

 and the results were very gratifying on both plums and cherries. It 

 was used at about 2 pounds in 50 gallons of water or Bordeaux mix- 

 ture and applied thoroughly two or three times soon after the blos- 

 soming period. Recent experiments in other States show that this 

 poison is more effective than Paris green and similar poisons in fight- 

 ing the codling moth. Thus the indications are that arsenate of 

 lead will come into more general use. 



AN HISTORICAL NOTE ON THE CODLING MOTH. 



We insert this note simply to place on record some observations on 

 the eggs of this insect which were recorded in Italy in 1857. The 

 account was overlooked in some unaccountable way when we made 

 an exhaustive survey of its early literature in 1898. In 1857 A. Costa 

 published an important work on the insects infesting fruit trees and
