Destroy larvae as soon as the tents appear ; do this 

 early in the morning or late in the evening, when they 

 are all in their tents. (3, III., 117; 4, II., 181 ; 5, II., 

 143)- 



The Tent-caterpillar of the Forest, Clisiocampa 

 sylvatica Harris. — Note habits, and compare with the 

 preceding species. (3, III., 121). 



The Fall Web-worm, Hypliantria textor Harris. — 

 Eggs laid in a cluster on a leaf; they hatch during 

 June, July, and August. The larvae spin a web under 

 which they live and feed, increasing the size of the 

 net as they require more food. They are found on 

 many kinds of trees, but especially ash. This species 

 is generally single brooded, and winters in the pupa 

 state. The moth emerges during May or June, and 

 is pure white. 



Compare this species with the Apple-tree Tent-cat- 

 erpillar, and note differences in habits. 



Remedy. — Destroy the larVc-E as soon as the webs 

 appear. This may be done at any time of the day. 

 (3. HI., 130). 



To the old genus Attacus belong several very large 

 common moths. The larvae live on various fruit and 

 forest trees, and spin dense silken cocoons, which, in 

 some instances, at least, might be utilized in the man- 

 ufacture of silk. The following species are found at 

 Ithaca. 



Telea {Attacus) Polyphemus Linn. — The moth is 

 brown with large transparent eye-like spots in the 

 centre of the wings. It expands five inches. The 

 larvae feed upon oak, walnut, hickory, bass-wood, elm, 

 maple, hazel, apple, rose, quince, thorn, plum, choke- 

 cherry, sycamore, poplar, birch, honey-locust, blue-
