252 STATES OF INSECTS. 



regalis the channel is between the sixth and seventh, and 

 in B. imperatoria there are three, namely, a channel be- 

 tween the third and fourth, and fourth and fifth, and fifth 

 and sixth segments. The way in which insects with an 

 exserted sting fold it in the pupa seems not to have been 

 noticed ; but from an observation of De Geer upon one 

 species of Ichneumon, it appears to be turned up over the 

 back of the abdomen a . 



These little animals, thus swathed and banded, exhibit 

 no unapt representation of an Egyptian mummy ; though 

 Lamarck applies the term Mumia to incomplete pupae b , 

 to which it seems less happily applicable. 



Chrysalises, as to the modifications of their general 

 figure, maybe conveniently divided into two great classes : 

 Jirst, those that have no angular projections, the anal 

 mucroof some excepted, on different parts of their body; 

 and secondly, those which have such projections. Each 

 of these classes affords variations in its peculiar charac- 

 ters which require to be noticed. 



1 . The first of these are called angular pupae c , and 

 are confined to the Butterfly or diurnal tribes. In some 

 the head projects into one short conical protuberance : 

 this you may see in the chrysalis of the common cabbage 

 butterfly (Pieris Brassicce), and others of the same ge- 

 nus d ; in the brimstone-butterfly (Colias Rhamni% and 

 in the beautiful purple emperor or high-flier ( Apatura 

 Iris F. f ): though in this last it is not conspicuous. But
