of fight under the prefent infects fein. 
aa Its two antenne or horns. 
5b The two thanks of the probofcis. 
cc Parts like forks. 
dd The eyes. 
ee The upper and lower pair of wings, be- 
tween which are to be feen the legs growing 
from the thorax. 
Ff The tings of the body. ' ¢ The tail. 
E TGs ill. 
The natural difpofition of fome of the latent limbs 
reprefented by the laft figure, as appears through 
the microfcope. 
aa The place where the horns or antennz are 
jointed with the head, and from thence are 
regularly turned back, and folded in a fer- 
pentine manner. 
66 ‘The two fhanks of the probofcis, difplaced 
a little from their natural fituation. 
ec The forky particles in their natural fituation. 
dd The eyes in their natural fituation. 
e A portion of the fkin, that lay over the mid- 
dle of the fkull, which is in this place re- 
moved. 
Jf The root of the probofcis. 
g The forks, between which the infec, 
when become a Butterfly, curls up its pro- 
bofcis. 
Pr teGe lV, 
The Caterpillar beginning to fhed its fein. 
aa The eight intermediate legs rolled off to- 
wards the tail, and fhedding their fkins. 
b The fix fore feet, feparating from each other, | 
and flipping forwards. 
¢ The fkull divided into 'three parts, the 
middlemoft of which is here reprefented. 
d Another portion of the divided fkull. 
e The third portion. 
Ff The forky particles, which are the parts of 
the future Butterfly, that appear firft. 
Ge 
The Caterpillar in greater forwardnefs towards 
the Chryfals flate. 
aa The eight intermediate legs now driven 
higher towards the tail. 
4 Four of the fore pair of legs rolled off as far 
as the middle of the body. 
ed The forky particles entirely divefted of their 
fkin; and the divided fkull; and the firft

7 FIG. VE 
The Caterpillar after it has quite thrown off its 
Sein; fo as to acquire the name of Chryfalis. 
a The wings, horns, probofcis, and legs, all - 
of them extended, and of another form. 
4 The rings of the abdomen ftripped of its 
fkin: Thefe are now more ‘comprefled to- 
wards each other than heretofore. It here 
appears in what manner the Chryfalis, by 
means of the nails in its tail, continues fuf- 
pended by its web. 
FIG. VII 
All the parts or limbs juft now mentioned, as they 
appear through the microfctope. 
aa The forky particles, which are no longer 
to be feen in the Butterfly. The third figure 
exhibits them under the letters ¢ c, in their 
natural fituation. . 
6 The middle portion of the head, which 
heretofore lay under the fkull, and is repre- 
fented in the laft mentioned third figure, 
under the letter ¢. 
cc ‘The root of the probofcis reprefented in the 
fame place under the ietters ff. 
dd The probotcis itfelf denoted by the let- 
ters 5b. 
e The extremity of the probofcis fo much ex- 
tended, as to reach the rings of the abdo- 
men, and placed between the antennae. 
Sf The firft pair of legs. 
&g The fecond pair. 
6 The antenne or horns, whofe origins or 
rudiments are exhibited by the third figure 
under the letters a a. 
zz Their extreme ends, which are very thick. 
kk ‘The eyes, under which the horns lie bent. 
Thefe eyes are reprefented by the letters dd 
of the third figure. 
111 The wings placed in each fide of the 
body. 
mm The nervous divifions of the wings. Thefe 
divifions are in reality no more than pulmo- 
nary tubes. 
nn The rings of the abdomen clofed and 
folded one over another. 
oo Some prickly hairs like papille, divefted 
likewife of their {kins and feated on the in- 
fect’s back, from which they project a little. 
More forwards may likewife be feen four 
breathing holes. : 
p The tail freed from its fkin, as likewife the 
anus. 
q The nails of the tail, and the manner in 
the infect ufes them to faften itfelf to the 
web.
