Tho a StI? Or ¥y of, TNS ae TyS: 
tains the body of the creature, is again con- 
tracted, and therefore it is formed like a big- 
bellied cylinder. 
I have feen three forts of creatures produced 
from thefe Worms; for as one of thefe fmall 
creatures had, according to the fecond mode 
of the third order, been changed intoa Nymph, 
which aflumed the form of the future Butter- 
fly, I at length obferved a pretty little noctur- 
nal Butterfly or Moth, not much different from 
the Cloaths-Moth, fprung d out of it. Ifawa 
black Fly e with two horns, four wings, and fix 
legs, produced from another fimilar Nymph, 
which however fhewed before the form of a 
Fly, according to the firft {pecies of the third 
order. But the moft fingular event of all was, 
fix or feven very {mall f Flies, which, from 
more tender Worms, had been firft tranf- 
formed into Nymphs, iffued out of another 
Chryfalis of fuch a Vermicle as belonged to 
ror 
the fecond mode of the third order; Whether 
this be cgmmon, and conftantly happens an- 
nually, as is the cafe in other Caterpillars; or 
whether it be peculiar only to thofe that in- 
habit the bright brown cells, in which only I 
obferved it, I have not indeed yet learned from 
experience. And, indeed, what man can per- 
fectly inveftigate all the changes of parts which 
happen, even in one creature. I am, in- 
deed, every moment taught by experience; 
that nature is, in regard to thofe real caufes, 
by which animals and their parts increafe, in 
many particulars, perfetly impenetrable to 
man. , However, a firm and conftant diligence 
hath, by degrees, difcovered to. me more than 
_one could eafily believe ; though what we are 
ignorant of is, and, will remain, much greater 
than all we know. Hence, indeed, we have 
knowledge of many things; but our ignorance 
ftill prevails and predominates. 
Of certain Vermicles or We or ms, whofe eggs are lodged in the bags wherein 
miufk is brought to us. 
Should never make an end, if I attempted 
even to enumerate all the hidden changes 
of the Caterpillar and Worm kinds into winged 
infe@ts; fo fruitful and manifold is Nature in 
her genera and fpecies! For this reafon I fhall 
only add the following obfervation, and after- 
wards finifh this hiftory of the fourth order, 
with accounts of two Worms which live in 
tubes, one in the earth, and the other -in the 
water; for the water abounds as much with 
thefe infects as the land. 
On the roth of July I found a great many 
fmall white Worms, Tab. XLV. Fig. xxxir. 
in a bag, wherein mufk comes to us. All 
thefe had a reddifh brown head, and black 
teeth. Six.legs adhered to the breaft. The 
body was covered with fine hairs, ftanding 
ere€t. © This mufk-bag was in a little box, not 
very clofely fhut, the bottom of which was 
covered with white paper, through which thefe 
Worms penetrated into the wood of the box, 
by various holes which they gnawed through 
it. And indeed thofe holes, which are as con- 
fpicuous in the paper as in the wood, moved 
the admiration of the perfons who viewed 6 
them. As they were bit regularly into a round, 
oblong, or oval circumference. I further ob- 
ferved, that many of thefe Worms made them- 
felves in their caverns a pretty thick, oval, 
lemon-coloured web, whereon they had weaved 
many cotton-threads, after the bag of mufk 
had been placed in the cotton. 
When I opened thefe webs, I found real 
Nymphs in them, Tab. XLV. Fig. xxx11. d, 
which belonged to the firft mode of the third 
order; for each very diftinély reprefented the 
limbs. of a future Beetle. Some of thefe 
Nymphs were very white; but in others, 
which were older, the eyes were turned black, 
and, the whole Nymph, from white, infenfibly 
became tinctured with various colours; atid 
was, at length, changed e into a very beautiful 
little Beetle, after cafting its fkin. When thefe 
Beetles have newly caft their fkin, in which 
they appear like Nymphs, they are of a fnowy 
white colour: they afterwards grow yellow by 
degrees, till at laft they become of a dufky 
purplith hue, and afterwards always continue 
fo: fome of them, however, conftantly pre- 
ferved a colour between yellow and red. 
They are diftinctly divided into the head, 
_ thorax, and belly. They have two black eyes 
in the head, juft over which project two redith 
horns, thick fet with fine hairs of the fame 
colour. The thorax is likewife adorned with 
yellowith hairs, that glitter almoft like gold, 
and exhibit fix hairy legs of the fame colour 
with the horns, affixed to its lower region. 
The cafes or covers of the wings are divided 
with ribs; and the latter, together with feveral 
little depreffions, are every where fet, as it were, 
with fine hairs. ‘This obtains chiefly about 
the fhoulder-blades, and on the hinder part, 
where thefe cafes or covers are bent, near the 
extremity of the abdomen; for they have a 
tuft of whitifh hairs in the fore and hinder- 
moft parts. The under win gs are membrana~ 
ceous, and they very expeditioufly fold them- 
felves under the fheaths or cafes with which 
they are covered, notwithftanding their being 
twice the length of the abdomen. 
This fpecies of Beetles may, on account of 
the conftruction of the horns, be referred to 
the flying Capricorn kind. Ihave {een Beetles 
produced from fome other fpecies of Worms, 
that live on rotten and hollow wood; the horns 
of which were formed in the fame manner as 
the Silkworm Butterflies. The only difference 
was, that all their divifions or plates were fe. 
verally jointed together. This ftruture formed 
a very beautiful fight, and clearly demonftrated 
the wifdom and art of the Creator. This is til]
