Leaf-Folder Injuring Apple. In many parts of the state apple 

 trees were considerably damaged by a small larva which fed 

 upon the leaves and folded arid fastened the edges together. At 

 Stonington this pest seemed to be more injurious than around New 

 Haven. Though we did not obtain the adults, it was doubtless 

 the apple leaf-folder, Ancylus nuheculana Clem., a small moth 

 of the family Tortricidce, having a wing-spread of about five- 

 eighths of an inch, and brown and white in color. Ordinarily 

 this insect is not troublesome, but was injurious enough at 

 Stonington to warrant spraying. Lead arsenate is advisable for 

 this. 



Leopard Moth in Connecticut. This insect in its larval stage 

 is one of the worst pests of shade trees in the vicinity of New 

 York City, boring in the twigs and branches, the symptoms being 

 dead limbs projecting above the leafy branches. The leopard 

 moth, Zeuzera pyrina Fabr., was introduced probably by acci- 

 dent from Europe, and first noticed in this country near New 

 York about 1882. Since then it has been spreading northward, 

 but was not known to have reached Connecticut until July ist, 

 1907, when Professor H. W. Foote captured in New Haven two 

 specimens, which are now in the station collection. This insect 

 is also serious in the vicinity of Boston. The adult has a wing 

 expanse of about one and one-half inches, the wings being whitish 

 or transparent, marked with a large number of small dark gray 

 or black dots. The body is nearly black. 



Infested branches will often wilt, and can be cut away and 

 destroyed before the borers escape. Carbon disulphide may be 

 injected into the burrows, and the opening stopped with clay, 

 hard soap or putty, to kill the larvae. 



Appearance of Corn Ear-Worm or Boll-Worm, Heliothis 

 obsoleta Fabr. Some larvae and their work were brought to the 

 station from Bethany on October 28th. The writer saw this insect 

 in New Haven some twelve or thirteen years ago, but has never 

 happened to see it since. The larva attacks corn, eating the unripe 

 kernels at the tip of the ear, also tomato, cotton, and several 

 other cultivated plants, though in the Northern States it is not 

 a very serious pest. The adult is dull yellow, with dark markings, 

 and the larva appears in a variety of colors, such as green, brown,
