g Another of the third pair of legs, joined 
under the fourth ring. | 
5. The fifth ring, on the other fide of which 
there appear three prickly hairs. 
b A prickly hair placed in the middle of the 
Caterpillar’s body, like that which is placed 
on each of the twelve rings. 
3 The firft and largeft prickly hair, placed on 
the other fide of the body ; under and near 
which is feen a fecond, and under it another 
breathing hole. 
k A third prickly hair under the belly. 
6 The fixth ring, formed like the fifth, con-

II/1 Four of the middlemoft legs, together

~ claws; joined in the bending part of the 
body, each with its ring. 
11 The eleventh ring, formed like the former, 
~ in which is placed another of the eighth pair 
of breathing holes. 
12 The twelfth ring, differing from the reft 
in the number of its prickly hairs. The reft 
of the nine breathing holes above it, are 
feen placed in this fide of the body. 
13 The thirteenth ring, adorned at leaft with 
two prickly hairs. 
mm The tail and the laft pair of legs, placed 
in the extremity of it.

are the clofed inteftines, conftituting, as it 
were, twelve little inteftines. 
Jf The place, in which thefe inteftines, below 
the pylorus, are produced from the inteftine 
~ next the ftomach. 
gg The manner in which the fame is bent into 
fix little tubes, and turned back towards the 
ftraight gut, again{t which they are folded 
_ and curled. 
4 Their windings and foldings, 
z One of the thick inteftines, in which the 
excrements receive their form; fo that it is 
not unlike the colon. 
k The ftraight gut. 
Brig ay: 
Two veffels hitherto unknown, which lie in folds 
near the ftomach 
aa Two tubes, which might very well pafs 
for filk bags. 
6b The origin of thefe tubes, afcending to- 
wards the brain ; they are very narrow in 
this place. ue 
c Swellings in thefe tubes. : 
d Their {harp extremities, inferted lower down 
near the blind guts.

bb 6, &c. Mutcles fituated on each fide of 
the heart, which they ferve to dilate.

c The firft nodule of the fpinal marrow. 
dd Two pair of nerves, arifing immediately 
from the fpinal marrow, which produces 
three pair more in the fame manner. 
e The fecond nodule of the {pinal marrow. 
fj The fourth and greateft cleft or flit of the 
{pinal marrow, below the third nodule. 
gb The fourth and fifth nodules, with the 
fingle nerves {pringing from them, | 
tkhilmn The fixth, feventh, eighth, ninth, and 
tenth nodules of the {pinal marrow, with the 
four nerves iffuing from each nodule.

Ibe web formed by the Caterpillar, when about 
to enter the Nymph late. 
a The Caterpillar’s web, in which it fixes the 
nails of its hinder feet, and fo remains fuf- 
pended head downwards. 
6 The third and fourth tings of the thorax, 
confiderably diftended by the blood and air, 
that dilate the latent wings and legs. 
c Eight intermediate legs, which lofe their 
fkins by degrees, and are at length flipt off 
towards the tail. 
d The firft order of legs, which are likewife 
about to fhed their fkins, and roll off one
