NOTES OF THE SEASON. 



THE LESSER APPLE LEAF-FOLDER. 

 {Tortrix. malivorana, LeB.) 



A brief account of this insect was given by the writer in his first 

 annual Report. We refer to the subject now merely to add that the 

 apprehensions which were naturally entertained of its increase and dif- 

 fusion, have not been realized in the experience of the present year. 

 Whether it be that they have been destroyed by natural enemies, or 

 what seems more probable, in the absence of any known enemies of this 

 kind, that they are very susceptible to the vicissitudes of the weather, it 

 is a gratifying fact that the hosts of last year have entailed a very 

 scanty progeny upon the present. I visited Mr. Wier's place this 

 season, at about the time of my last year's observations, and though 

 there were marks of damage by the early spring brood, the second 

 brood seemed, for some reason, to have proved abortive. I could find 

 but few specimens, and the nursery trees had made a good growth and 

 presented none of the blasted aspect which they exhibited the previous 

 year. 



OYSTER SHELL BARK-LO0SE. 

 {Mytilaspis conchiformis.) 



In treating of the remedies for the Apple Bark-louse, in the author's 

 first Report, reference was made to the various applications which have 

 been used for the purpose of destroying the eggs under the scales, it 

 being very desirable that some such remedy shall be found, inasmuch 

 as it can be applied in the early spring, when the farmer is more at 

 leisure, and when the foliage, being yet in the bud, is not exposed to 

 injury.
