moth, named hy the fancy the Glory of Kent 
( Endromh versicolor), which are bright yellow on 
their first exclusion, and then become successirely 
green, rose-colour, and black. 
The profuse fertility of most insects is well knoivn, 
and the subjects of the present notice partake largely 
of this general attribute of their race. The Silk- 
worm-moth, for example, lays about 600 eggs, the 
Goat-moth 1000, and the Tiger-moth 1600. They 
are deposited either singly or in groups, and in the 
latter case are often arranged in a uniform symme- 
trical order by the parent moth, a process in which 
she manifests great ingenuity and prospective care, 
both for the preservation of the eggs and the welfare 
of the future young. The insoluble gum ^vith which 
they are usually covered, protects them from the in- 
fluence of the weather when they are left exposed. 
But in many cases they are placed under some kind 
of shelter, and several species cover them mth down, 
which they pluck from their ovra bodies by means 
of a pair of anal pincers 'with which they are pro- 
dded apparently for this express purpose. 
The caterpillars of moths arc much more varied 
in their general forms and in the structure of their 
parts than those of butterflies, and indeed they may 
be said to be formed on a greater variety of models 
than most other animals. Their clothing and ap- 
pendages are likewise extremely various ; every kind 
of the former found in butterfly-larvae being ob 
served among them, besides several others peculiar 
to themselves. One of their most important varia-
