Moth.—This is our most common pug-moth, and may be distinguished by the pointed 
fore wings, with the numerous transverse lines angulated sharply outward, the extra- 
discal line forming a sharp angle opposite the discal dot, and notched inward on the 
subcostal vein; by the distinct submarginal wavy white line ending in a large white 
twin-spot at the inner angle; by the fine dark lines on the hind wings, and by the

2. THE JUNIPER WEB-WORM. 
Dapsilia rutilana Hiibner. - 
Order LeEpIporpTERA; family TORTRICID£. 
Ravaging imported junipers, webbing the leaflets, and living within a more or less 
perfect silken tube, in which the caterpillars hybernate, the twigs and branches present- 
ing a seared and brown appearance. 
The following account is taken from 
Professor Riley’s report to the Depart- 
ment of Agriculture for 1878, with the 
accompanying illustration. 
This leaf-roller has been found to 
seriously injure the imported Irish and 
Swedish junipers (Juniperus communis 
var.) in nurseries on Long Island, hav- 
ing first become known in this country 
in 1877; it has.not yet been found on 
our native juniper. It is a well-known 
English and German moth. There is 
one annual brood of worms. The insect 
hybernates at different stages of larval 
development, and the chrysalis is found 
throughout the spring months. ‘The 
moths begin to appear as early as April, 
but continue to issue during the sum- 
mer. The worm from birth webs the 
leaflets together, and, lives within a 
more or less perfect silken tube, this 
tube being more complete around the 
hybernating individuals. The sprigs Fie. 96.—The Juniper web-worm; a, sprig of
