ly enlarged. The first segment has two, a quarter of an inch long, 
the second and third segments have each four prominent orange horn¬ 
like prominences two or three times as long as those on segment one. 
The eleventh segment has one horn larger than the rest on the seg¬ 
ment. It feeds on black walnut, butternut, hickory, persimmon and 
sumach. 
Eacles imperialis, Hub.—The Imperial Moth. 
The wings of this species are broader than the preceding, the lar¬ 
ger specimens expanding five and a half inches. They are a rich 
yellow color, spotted with purple brown and each ring crossed by 
bands of the same as follows: one oblique from the apex to the hind, 
margin merely straight, the other wavy arcuated near the base. 
The caterpillar, which feeds on the buttonwood, is when full grown 
“from three to four inches in length, and more than half an inch in 
diameter, and, for the most part, of a green color, slightly tinged with 
red on the back,” there are a few very short hairs scattered over the 
body. It is but slightly tubercled. 
Dryocampa rubicunda, Fab.—The Rosy Dryocampa. 
This delicate moth with rosy fore wings crossed by a broad yellow 
band is the parent of a caterpillar that occasionally proves very 
destructive to the red and silver maples. This caterpillar, called the 
Green-striped Maple Worm, is striped longitudinally with two shades 
of green lines. On the top of the second segment there are two black 
horns projecting backward on the eleventh segment. The posterior 
part of the body is rose colored. There are two broods of the worms in 
a season, the first in June or July, the second in August and Septem¬ 
ber, the latter passing the winter in a crysalis state. The cry- 
salids are subterranean. The moths expand from an inch and 
three quarters to two inches and a quarter; the fore wings 
are rose colored, crossed obliquely by a broad yellow band, 
with, at times, some of the yellow in the outer margin. The 
hind wings are pale yellow with a short rosy band beyond the 
middle; the body is yellow, antennae, short, broadly pectinate in the 
male. It is subject to the attack of several parasites so that it is sel¬ 
dom numerous more than a single season in a given locality. Ihere 
is a variety of this species with the wings nearly w r hite. 
Dryocampa (Anisota) senatoria, Smith—The Senatorial Dryocampa. 
This is somewhat larger than the preceding and the wings are ; 
broader. It is of an ochre yellow color, the wings tinged with purp¬ 
lish brown, and a narrow oblique band of the same crossing each
