JANUARY. 



Pupa incompleta, inactive, but withrudimental legs and 

 wings : example. Apis, the Bee. 



Pupa obtecta, the thorax and body distinct, enclosed in 

 a scaly covering, and either naked or in a cocoon : example 

 Lepidoptera, the Butterfly and Moth. 



Pupa coarctata, enclosed within a cae formed of the 

 skin of the larva : example, Musca, the Fly. 



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- 

 ticularly Latreille ; but leaving these somewhat intricate 

 questions, we will endeavour rather to gain a general idea 

 of this state of the insect world, which 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 development of the 

 perfect insect shall not take place till its proper sustenance
