56* EMPEROR MOTH, 
end, and narrow at the other. The ca- 
terpilhir of the emperor moth makes its 
case somewhat in the last shape, as you 
may perceive from this empty one, which 
I have preserved since last year: and 
here are drawings* of the moth it pro- 
duced, and of the caterpillar and pupa. 
Lucy. Oh, what a pretty caterpillar! 
How very heautifal the moth is; and this, 
1 see^ is the outer case ! What a curious 
shape. It looks as if it had been gummed 
over ! But how could the caterpillar 
gum the outside of the case, after it had 
spun itself up withinside ? 
Mother, The outside was first formed 
with thinly woven silk^ glued together by 
a shining substance ; and within^ there 
is a thick web of silk, crossed in every 
direction ; now, observe the narrow end> 
do you see that it is jagged ? 
Lucy. Yes, and below this jagged 
edge is another row of jags, and under- 
neath that another and another.
