ments. In Ceracampa regalis the channel is between 
the sixth and seventh, and in C. imperatoria there are 
three, namely, a channel between 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 ob- 
servation of De Geer upon one species of Jchneumon, 
it appears to be turned up over the back of the abdo- 
men *. - 
These little animals, thus swathed and banded, ex- 
hibit no unapt representation of an Egyptian mummy; 
though Lamarck applies the term Mumia to incomplete 
pupze », to which it seems less happily applicable. 
Chrysalises, as to the modifications of their general 
figure, may be conveniently divided into two great 
classes : first, those that have no angular projections, the 
anal mucro of some excepted, on different parts of their 
body; and secondly, those which have such projections. 
Each of these classes affords variations in its peculiar 
characters which require to be noticed. 
1. The first of these are called angular pupze‘, 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 cab- 
bage butterfly (Pontia Brassice), and others of the 
same genus‘; in the brimstone-butterfly (Gonepteryx 
Rhamni*), and in the beautiful purple emperor or
