pearance of net-work. In the’ others, as in a common 
butterfly (Hipparchia Atgeria) and moth (Ennomos cra- 
tegata), the whole surface is covered with hexagonal re- 
ticulations *. Others, as those of another butterfly (Hzp- 
parchia Hyperanthus), are beset with minute granules or 
tubercles. Others again, like those of the cabbage and 
hawthorn butterflies (Pontia Brassice and Pieris Crateg?), 
are remarkable for beautiful longitudinal ribs, often con- 
nected by elevated lines crossing them at right angles‘; 
and in some, as in another butterfly (Azpparchia Janira), 
crowned by imbricated scales ‘4. Many other minor dif- 
ferences in this respect might be noticed, but these will 
suffice to give some idea of the infinite variety exhibited 
in this respect by these little atoms. If the Creator has 
wrought them with so much art and skill, can it be be- 
neath his reasonable creatures to examine and admire 
them, that they may glorify those attributes which they 
serve to illustrate ? 
Some eggs after exclusion occasionally become slightly. 
corrugated: Malpighi supposed that this occurs only 
when the eggs are barren, having observed that those of 
the moth of the silk-worm which preserved their plump- 
ness always produced caterpillars, while those which lost 
their original rotundity and became wrinkled were con- 
stantly unprolific. Bonnet, however, found exactly the 
reverse take place in another moth®, so that these ap- 
pearances are scarcely to be depended upon. Kuhn as- 
serts, that a virgin female of the puss-moth (Cerura 
Vinula) having begun to lay eggs, which were yellow | 
above, green below, and depressed, he introduced to her
