The first of these is now inadmissible, as the creatures 

 composing it are no longer classed with insects. More 

 modern entomologists have altered these arrangements, par-

 questions, we will endeavour rather to gain a general idea 

 of this state of tJie insect world, whicli is interesting from 

 its being prior to the imago or perfect condition. 



Pupae are generally of a dirty white colour, when their 

 habitation is underground ; some however are of a dark 

 bright brown, and those which have more exposure to the 

 action of light are variable in their tints, some being of 

 bright colours and gilded, as in the chrysalides of many 

 Butterflies. The period passed in the pupa state depends 

 greatly on the temperature of the atmosphere, as Provi- 

 dence has wisely ordained that the developement of the 

 perfect insect shall not take place till its proper sustenance
