ravages in some of these localities may have been caused by the forest 

 tent caterpillar, CHsiocampa disstria Hiibn. 



I have found no record of serious injury to maples by this species, 

 though Dr H. G. Dyar, in a recent letter identifying the insect, informs 

 me that it is somewhat injurious to soft maples at Bellport, Long Island, 

 but that they were less common than usual the present season. This 

 insect, or closely allied species, has been known for a number of years 

 as injurious to apples and pears, and in 1896 and 1897 it caused con- 

 siderable damage in this state to these fruits, but this appears to be the 

 first record of serious injury to soft maples by a species of Xylina. 



An elm-leaf miner. This insect has been unusually destructive in 

 Albany and Troy the present season. For the past three years the 

 Camperdown elms in Washington park, Albany, have suffered rather 

 severely from this species. The present season the miner not only seri- 

 ously injured the Camperdown elms but extended its ravages to the

English, Scotch and American species. From half to two- thirds of the 

 leaves on certain English elms in Troy were nearly destroyed by this 

 insect (fig. 17), and many others presented a sorry appearance on account 

 of the numerous mines.
