Saturniidae 
each joint than the posterior pair. The genus is quite large, but 
only one species occurs in temperate North America. It is better 
represented in the Old World. 
(i) Actias luna Linnaeus, Plate XII, Fig. 7, $. (The Luna 
Moth.) 
This common and well-known insect has an extensive range 
from Canada to Florida and westward to Texas and the trans- 
Mississippi States as far as the region of the great plains. The 
larva, of which we give 
a representation, feeds 
upon the various species 
of walnut and hickory, 
the sweet-gum (Liqui- 
dambar), the persimmon 
(Diospyros), and other 
trees. In North Caro¬ 
lina it appeared to be 
particularly fond of the 
persimmon. The cocoon 
is thin and papery, spun 
among leaves, and falls 
to the ground in autumn. 
In consequence it is not 
nearly as often found as those of some other species, which 
have been described in the preceding pages.

Genus TELEA Hubner 
This is a very small genus, including only two or three 
species. It is confined to the New World. The only represen¬ 
tative in our faunal limits is the well-known species, which we 
figure.

Polyphemus Moth.) 
Syn. paphia Linnaeus; fenestra Perry; oculea Neumcegen. 
This very common moth feeds in the larval stage upon a 
great variety of trees and shrubs. I have found the caterpillar 
upon various species of oaks, upon the two species of Juglans , 
which grow in the Eastern States, upon hickory, basswood, elms, 
maples, birches, chestnuts, the sycamore (Platanus), wild-
