that the males of Locufts only make this noife, 
not the females: indeed fome {pecies make this 
noife with their wings only, and others by 
ftriking their wings and legs together. 
The Locufta Pulex, or Flea Locuft, follows. 
This little creature is found hid in that fpumous 
matter, which we fometimes fee lying indif- 
criminately on the furface of all kinds of plants*. 
In this {fpume + it acquires in time four 
tubercles on its back, wherein the wings are 
enclofed. I have two fpecies of this infect, 
and it was likewife known by Mr. Ray, who 
defcribed the plants growing about Cambridge. 
It has not teeth like the Locufts, but has 
only a fubtle fharp-pointed probofcis or trunk, 
like Grafshoppers, on its breaft. 
Werefer alfoto this fecond clafs the Gryllus 
Sylveftris, or wood Cricket ; in which infect 
we alfo obferve that the male only fings, or 
makes a noife. I remember that I once fawa 
‘whole field full of thefe finging Crickets, each 
of which had dug itfelf a hole in the earth, 
two fingers deep, and then fitting at the en- 
trance thereof, they made a very difagreeable 
noife with the crafhing and tremulous motion 
of their wings; when they heard any noife 
they immediately retired, trembling, into their 
little caverns. 
The houfe Cricket is the next to be reckoned 
in this fecond clafs; fince this, like Locufts, 
has alfo its wings enclofed in little cafes, as long 
as it remains in the habit of a Nymph. 
We likewife rank the common Grafshopper 
in this clafs. For although the larger Grafs- 
hoppers are not found in our part of the Ne- 
therlands; we, notwithftanding, by inference 
from the lefs to the greater, refer them to this 
place ; and the rather, becaufe the very diligent 
Aldrovandus hath left us a delineation of this 
Worm, with its tubercles on its back, wherein 
the wings like a flower in its cup are enclofed ; 
as this Worm is called Tettigometra by him, 
it is the real Nymph of the Grafshopper. I 
preferve a very rare and curious exotic Grafs- 
hopper, the head of which is formed like a 
long and deep epifcopal mitre, fo that it ap- 
peared four fifths of an inch above the eyes, 
. exhibiting us a wonderful work of God in the 
theatre of nature. We mutt alfo obferve again, 
that the male Grafshoppers only can fing, and 
we can fhew their tympanum, and alfo the little 
part that modulates or tunes the voice, or im- 
pels the air againft the tympanum, 
The Gryllo Talpa or Mole Cricket, or the 
Talpa Ferrantis Imperati, likewife belongs to 
this clafs; fince, like the infects hitherto def- 
cribed, it has four tubercles on its back, where- 
in the wings are enclofed. We have the Worm 
of this infect with and without tubercles, as 
ame 
alfo the infects themfelves, with their wings 
difplayed. The induftrious Goedaert has dei= 
cribed the egg of this infe@. We can alfo 
fhew its teeth, and the manner wherein the 
wings lie complicated in their tubercles. 
In this I alfo reckon a little creature, which 
is found in the tubercles of the leaves of the 
black poplar, though I might have defcribed 
it in the fourth order or clafs, becaufe it has a 
more fecret method of changing. It is deli- 
neated in figure xxiv. of Tab. XLV. To 
this order I likewife refer another infect, which 
is likewife reprefented in fig. vir. of Tab. 
XLIV. and is found in the tubercles or fwellings 
of willow trees. 
The next we exhibit is the Indian infect, fuf= 
ficiently known by the name of Kakkerlak, 
which we think likewife belongs to this fecond 
clafs. As we have obferved the tubercles before- 
mentioned in its wings, though not having 
attained their full bignefs their wings did not 
appear perfect ; for the fame reafons, we think 
we fhould refer to this order that {pecies of 
Beetles which are commonly found about 
bakers ovens, and, according to Fabius Co- 
lumna f, in kitchen dirt. They agree alto- 
gether with the infects juft now mentioned, 
called Kakkerlak, and are the fame that are 
defcribed by Mouffet under the name of Blattz. 
We preferve two {pecies of them, together with 
their Nymphs, wherein the tubercles fcarce 
began to {well. 
Next follow the flying or land Bugs, which 
we find in fields and trees. I preferve twenty~ 
fix {pecies of them in my mufeum, together 
with a larger Indian one, which are very beau- 
tifully adorned by nature with variety of co- 
lours ; and as with their luftre and gaiety they 
wonderfully pleafe the eyes, fo they are very 
difagreeable to the fmell. Hoefnagel alfo has 
figured eleven kinds. Among thefe which are 
in our cabinet, we reckon the cruciate, the 
fcarlet, the red marked with black lines, the 
green, the black, the yellow, the globular, and 
that which has a {harp-pointed breaft. 
To this clafs we likewife refer the flying 
water Cimices or Bugs, of which we preferve 
four full-grown ones, and one Nymph. Thefe, 
like all the reft, carry their weapon in their 
mouth, and fting vehemently therewith, as I 
have fometimes experienced myéelf, though I 
fuffered no injury thereby, | 
We refer alfo to this order or clafs fome in- 
fects that are very tender and flow-paced, hav- 
ing fix flender and admirable legs, and long and 
acute horns, and a confiderable thick body; 
from the hinder part whereof, about the tail, 
{pring two briftly and fharp-pointed hairs, and 
they have likewife a fharp fting, as the Cimices 
* This is a fpecies of the Cicada or Cigale. The characters of that genus are very obvious on it: they are, that the beak is 
under the breaft, and is bent downwards; the antennz or horns very fhort; the wings four, and placed crofs-wife, the back con- 
cife, the breaft cylindrical, and the legs made for hopping. The Cicada of Italy, which the Roman poets mention, and which 
their tranflators render Grafshopper, is of this genus. We have alfo one on the rofe, and others on various buthes. ‘ 
_t This fpume is not exfudated, as fome fuppofe, from the plant, but from the mouth of the animal; and if it be well 
wiped away, without injuring the creature, more will be immediately feen iffuing out of its mouth, till there is as large a 
quantity of it as before.
