parchia Hyper an thus), are beset with minute granules or 

 tubercles \ Others again, like those of the cabbage and 

 hawthorn butterflies (Pieris Brassiccs and Cratagi), are 

 remarkable for beautiful longitudinal ribs, often connected 

 by elevated lines crossing them at right angles' 3 ; and in 

 some, as in another butterfly (Hipparchia Furtina), crown- 

 ed by imbricated scales . Many other minor differences 

 in this respect might be noticed, but these will suflice 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 beneath his 

 reasonable creatures to examine and admire them, that 

 they may glorify those attributes which they serve to il- 

 lustrate ? 



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 d , 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 

 an hour afterwards a male, and some minutes subse- 

 quently to the union, she again deposited eggs, which 

 were m holly of a dark brown and convex e .
