and soft pupa, it seems they know, that 

 in such a state it has not the power to 

 prevent them from doing it, by a strong 

 motion or throwing about ; and as the 

 females of these insects have no sting* 

 for laying eggs, they cover the pupa 

 with them, which stick so fast to it, that 

 they do not fall off by the increasing 

 hardness of the pupa. If after a short 

 time the little maggots want more nourish- 

 ment, they creep into the inside of the 

 pupa. 



The eggs are exceedingly small, and 

 hardly visible to the naked eye, and, 

 through the microscope, have nothing 

 uncommon with other eggs, therefore I 

 did not think it necessary to give a mag- 

 nified figure of them. The maggots, 

 when just crept out, are of the same size, 

 but as soon as they arc in the pupa, they 

 begin to feed upon the papilio, which 

 lays in a half liquid substance in it. This 

 now putrefies, and is at last totally con- 

 sumed, so that the skin of the pupa only 

 is left filled with maggots. Fig. 27. shews
