covers both is orifices of its little cafe, and caft- 
ing of its old fkin within, Tab. XLV. Fig, xxx1. e, 
is changed into a Chryfalis, which is properly re- 
ferred to the fecond mode of our third order ; 
becaufe it does not very clearly exhibit the limbs 
of the infect to be produced from thence: this is 
a nocturnal Butterfly, or Moth. When this in- 
fect is firft changed, all its parts are beautifully 
white, but they afterwards grow infenfibly yel- 
lowith, and at length acquire a faint red, which 
they finally preferve. In the head, particularly 
the eyes, which are feen through the fkin, firft 
acquire their colour and perfection; afterwards 
the whole body finally appears through the fkin, 
of the fame colour with the noGurnal Butterfly, 
to. be produced from thence, 
July 13th, the Butterfly appeared, f, after it 
had lain twelve or thirteen days under the form 
of a Chryfalis, without food or motion, and its 
tender limbs had, by the evaporation of the fu- 
perfluous humours, infenfibly acquired fufficient 
ftrength to break open the outmoft fkin. This 
Butterfly was provided with four wings, fix legs, 
two horns, and two black eyes. Its wings and 
body had many fuperb fcaly feathers, which very 
beautifully adorned the creature with various and 
agreeable colours. ‘Thefe colours being viewed 
witha naked eye, refemble fine flour, and may be 
eafily reduced to fuch a powder with the fingers : 
and therefore, frail man, as mentioned in {crip- 
ture, is very properly compared to a Moth. 
This little creature, the Butterfly, is com- 
monly called a Moth; though it is noxious on 
no other account, but that it lays thofe {phe- 
roidal eggs out of which the real Moths, or 
eating Worms, are at length produced, in 
hangings and cloaths, in like manner as the 
Flies producing Maggots lay theirs in meat, 
fith, cheefe; and meal. When thefe creatures 
fly or flutter about, thofe who would preferve 
treafure from Moths, mutt be careful to keep 
them from it; for otherwife their neglect will 
be a great hurt to them, and caufé much lof 
andconcern. Thefe are the confequences that 
commonly attend floth and negligence. 
When this Moth hath broken out of its 
woven cell, it is always obferved, Tab. XLV. 
Fig. xxx. g, to hang a little out of one ex- 
tremity of the {kin, which the Chryfalis had 
caft. But if the cafe itfelf be then opened, 
one may diftinctly fee how even and {mooth it 
is woven, 4 I fhould never finith, if I at- 
tempted to defcribe and delineate all the fpecies 
of Moths, fince there is a great number and 
variety of them. I fhould think, that what 
hath been hitherto faid is fufficient, fo that + 
there is no need of more; for it is eafy to know 
a Lion by his paw. 
Of certain Worms that, like the Moths, lve in cells, feeding on the leaves of 
Pear-trees, Apple-trees, Plum-trees, and Cherry-irees.

] Preferve, in my colle€tion, various and par- 
ticular {pecies of thefe Worms, fome of 
which form their cells of bits of wood, which 
they bite off; and hence are properly called 
Ligni perde: but of thefe I fthall hereafter 
treat in another place. The firft fpecies of 
thofe, of which I am to treat here, was fhewn 
me on the leaf of a Cherry-tree, by the very 
experienced and celebrated Dr. Luke Schaght, 
profeflor of the Materia Medica in the univer- 
fity of Leyden. I afterwards found it likewife 
on the leaves of the Willow and Alder-tree. 
The cell which this Worm inhabited was black 
as pitch, Fig. xxxIll. a5 and confifted of a 
fubftance, as it were, of bark, and woven into 
wrinkles.. Its hinder part was thicker than the 
fore part, and divided, as it were, into two 
lobes, Its foremoft extremity terminated fome- 
what acutely, and out of it crept its inhabi- 
tant, carrying this little cafe entire, obliquely 
on its body; but when the Worm refted, the 
cafe ftood perpendicular on the leaf. 
This Worm was, in régard to its ftructure, 
{carce different from the Moth. When it has 
eat enough, it fixes itfelf to the leaf, near the 
opening of its cell, and is changed within it 
into a Nymph of the firft mode of our third 
order, which 4 grows at length into a very 
beautiful Fly. On the head of this Fly, which 
is black, are placed two redifh horns. Its tho- 
rax and abdomen are partly red, and partly 
black. It has four beautiful membranaceous 
wings, which fhine like very fine Mother of 
Pearl; and are likewife variegated, nearly in 
the middle, with two black fpots. It has more- 
over fix red legs, which are divided into joints, 
each having two claws at its extremity. This 
creature is alert and fprightly, and flies very 
{wift.

Found a fecond fpecies of thofe Worms, 
which carry their cell with them, on the 
leaf of the Alder-tree. This creature fed on 
the inward coat of the leaf, and therefore con- 
famed it all unto the nerves of that external 
coat. It does not differ much from the former, 
except in refpect of its habitation, which it car- 
ries every where on its body: but in this there 
is a confiderable difference ; that is, it is of the 
colour of the leaves that fall in autumn, tho’ 
fome of thefe cells are alfo found of a ftronger 
colour. This cell is triangular, Tab. XLV. 
Fig. xxxiv. ¢, at the upper extremity: it {wells 
a little in the middle ; but the part that con-
