of the Plum Ciirculio, than they do from the work of this 

 Apple Curculio ; and this was so much the case in my own 

 locality the past summer, that I found a dozen larva? of the 

 former in apples, where I found one of the latter. 



[ At the meeting of the Society, Mr. E. Daggy of Tuscola, 

 Ills., had on exhibition some pears that were very much 

 deformed and gnarled. After the reading of this paper he 

 informed me that this injury had been caused by the Apple 

 Curculio, which he recognized from my figure and from the 

 specimens in the lecturing box. Upon examining the pears I 

 found a little dark circular spot, which indicated distinctly 

 where the snout of the beetle had been inserted. This spot 

 was the center of a hard and irregular but generally rounded 

 knot or swelling, which was sunk in a depression of the softer 

 parts of the pear, thus indicating that the growth, by some 

 property of the puncture, was checked and hardened, while the 

 other parts went on growing and swelling. Some of the fruit 

 was so badly disfigured that it could no longer be recognized, 

 and Mr. Daggy informed me that his Vicar of Winkfield, and 

 " Sugar Pear " were most affected in this way, and that his 

 Duchesse pears were unblemished.] 



THE SEASON OF THE YEAR DURING WHICH IT WORKS. 



The beetles come from their winter quarters and begia to 

 work on the fruit about the same time as does the Plum Cur- 

 culio, — if anything, a little later. They have generally got 

 fully to work, and larvse may be found already hatched, by the 

 first of June, and they may be found in the fruit in one stage 

 or another all along through the months of June and July, 

 and the greater part of August. 



REMEDIES AND PREVENTIVE MEASURES. 



Notwithstanding we have had reports published, in the 

 columns of our agricultural i3apers, of the relative number of 

 Apple and of Plum Curculios captured from peach trees by 

 jarring with the Curculio-catcher, I am fully convinced that
