As the second of the al^ve-named insects is of a scientific rather 

 than a practical interest, we have not thought it worth while to make 

 it the subject of a separate article, but to treat of it in connection with 

 its congener, the well-known Leaf-crurapler of the apple-tree. We have 

 been confirmed in this course, we will not say by the opinion, but 

 rather by the suspicion that these insects may ultimately prove to be 

 only plant-varieties, or, to use Mr. Walsh's more expressive term, 

 phytophagic varieties of one and the same species But this point we 

 shall treat of more fully in the sequel. 



Phycita nebulo is the scientific name of the little gray moth whose 

 larva forms those tufts of dead crumpled leaves which adhere to the 

 twigs of apple and plum trees all winter, and with which every or- 

 chardist is familiar. The first account of this insect was written by 

 the author of the present Report, and published in the September num- 

 ber of the "Prairie Farmer" for the year 1853. As this account gives a 

 brief and comprehensive outline of this insect's history, we here re- 

 prodjj&e it :
