of moment. The main difficulty lay in the 
fact that the early stage, during which 
the insect could be found in the leaf-stalk, 
was of very short duration, and if, in the 
pressure of other occupations, I forgot to 
note the unfolding of the buckeye leaves, 
or had not time to walk to the place where 
they grew, thechance for that year was 
gone. The buckeye unfolds very sud- 
denly and very quickly in the spring; 
consequently there are but a few days 
during which the caterpillar can be found. 
However, I have succeeded in obtaining 
some every year since, and in the two 
years 1880 and 1881 I reared a few to 
maturity. 
In the early part of May, usually about 
the second or third, I found the drooping 
leaves of the buckeye in great numbers. 
I gathered, 8 May, a quantity of the leaves, 
and, among them, a single specimen in 
which the caterpillar was in the main stem 
of the young shoot and not in the leaf-stalk 
— the only instance of the kind that I have 
met with. Taking the specimens home I 
placed them under a bell-glass im order to 
e 
determine the first point in doubt, the 
destination of the caterpillars after leaving 
the leaf-stalk. Two days afterwards, on 
sis 10 May, I found that the leaf-stalks were 
all empty and the caterpillars hidden in the 
faded leaf at the top of the stem in which 
they had previously burrowed. On 15 
May, five days later, the caterpillars were 
still in the dead leaves, and I went to the 
trees to try and find some more specimens, 
but was unsuccessful. However, on 21 
May, I found a few rolled-up leaves con- 
taining caterpillars, brought them home 
and placed them with the others. 
On 23 May the surviving caterpillars

were still feeding, but there were many 
dead ones. 
On 25 May I found the first chrysalis 
among the leaves. It was light red in 
color, with eight rings on the abdomen. 
The rolled-up leaf was lined inside with 
silk. These facts show nothing in any 
way peculiar, and the same description 
would apply to thousands of other chrys- 
alids. 
A caterpillar, examined on 13 May 1881, 
was one centimetre long, semi-transparent, 
yellowish in color with a yellow head, and 
this appearance was retained, except that 
the caterpillar became a little darker, until 
it went into the pupal state about 20 May. 
It was difficult to see what the caterpillars 
lived upon, as the fresh leaves that I put 
I have 
noted this point for several years and have 
with them were not attacked. 
come to the conclusion that the food of the 
larva is the dead, dry leaf in which it is 
rolled up. I have looked carefully on the 
trees and can find no eaten or nibbled leaves 
near those containing the caterpillars, so, 
apparently, its habit is the same, in this 
respect, both in captivity and in its native 
habitat. 
On 9 June, fifteen days after entering 
the pupal state, the first moth emerged. 
It was small, with a peculiar hopping 
flight, the fore wing mottled black and 
white, and the hind wing more uniform in 
color, dusky, and slightly spotted with black 
near the tip. 
It appears as if the second stage in the 
life of this insect is that in which it most 
frequently falls a prey to its foes. During 
its earliest existence it is sheltered in the 
tunnel it has bored in the stalk, and there 
seems no cause but the want of room to 
.
