BUG 
tyes, a little prominent; befldes two feelers with 
three joints, underneath which there is a crook- 
ed trunk, it's inftrument of annoyance, and which, 
when in motion, lies clofe upon the breaft. The 
breaft is a kind of ring, in which are placed the 
firft pair of legs. The belly confifts of nine 
rings, under which are placed tv/o more pairs of 
legs; each leg has three joints; and the feet are 
armed with crooked claws, refembling hooks. 
The body is fmooth, except a few fhort hairs 
about the vent, and on the two laft rings, which 
may be feen through a microfcope. It's .motion 
is flow and unwiddy; but it's fight is fo exquiftte, 
that, the moment it perceives the light, it generally 
makes good it's retreat, and is leldom caught, 
thougli the bed may fwarm v/ith the breed. 
If internally examined, we ihall find the great 
artery, which in all infedls performs the lunftions 
of the heart; we fliall likewife difcover the aper- 
ture of the lungs, on the right fide and on the left, 
through which the animal breathes ; and we fliall 
find a ftomach and inteftines running from the 
mouth to the anus. If the infeft has failed for any 
confiderable time, it's body will contain a mucus 
like the white of an egg; iDut, if cruflred after a 
full meal, the human blood which it has drained 
v/ill appear a little darkened by having paffed 
through it's body. 
The parts of generation in thefe animals are fuf- 
ficiently obvious; they are often found coupling 
tail to tail, and in that Hate are very eafily deftroy- 
ed. The female has an oviary filled with eggs, 
joined together like a bunch of grapes ; each egg 
being oblong, almoft cylindrical, inclining to 
white, and pretty tranfparent. In about two days 
after impregnation by the male, llie depofics her 
eggSj to the number of an hundred and fifty, in 
fome convenient place v/here they are likely to 
remain undifturbed: there they continue for fome 
months; during which time, neither heat nor cold, 
moifture nor fumigation, can in the leaft retard 
their exciufion ; but they come forth aftive, and 
endowed with the noxious qualities of the fpe- 
cies. This hardnefs of the Ihell feems to continue 
the breed, which might otherwifebe annihilated, as 
the old ones die every winter, or are eafily deftroy- 
ed by a fumigation ufed for that purpofe : but the 
eggs feem. incapable of defcruftion ; and even thofe 
who profefs to kill thefe naufeous infe£ls, though 
they may anfwer for the parent, can never make 
certain of the egg. 
The manner of deftroylng Bugs, notwithftand- 
ing the various prefcriptions v/hich have been pub- 
lifned, and the noftrums v/hich have been applied 
by individuals, feems rather the efte£l: of affidui- 
ty than of 3ntidote. Cleanlinefs is the moft efft^ftu- 
al preventative, and that alone will tend to exter- 
minate them. They are, however, of themfelves, 
an effeflual antidote againfl: other fpecies of ver- 
min, particularly fleas, which tJiey never fail to de- 
ilroy. 
llinnasus enumerates about forty fpecies of Bugs, 
to which, he gives the general name of cimex. 
Bug, Acolalan. An infe£t refembling the 
comm.on Bug, but lefs naufeous in it's fmell. It is 
very fmall; and, when full grovs'n, begins to aflTume 
wings. It is extremely mifchievous among cloaths, 
where it often comiiiits it's depredations unper- 
Ceived. 
Bug, Catep-Tillar. A name given by Bon- 
net to a fm?dl fpecies of caterpillar v/hich fmells 
cxadiy like a Bug. Tliis, however^ is not the only 
fpecies which yields a fenfible fmell ; for there h 
one of the middle-fized, fnooth kinds, which, at 
the time of it's change into thechryfalis fl:ate, emits 
a very pleafant rofe-like fcent ; and their exuvia; 
retain that fmell for years together. There is alfo 
another which fmells fl:rongly of muflc. 
Bug, GpvEEn and Yellow. This infe6l is 
about the fize of the common fly. The body is of 
an oval fhape, confiderably deprefled, and black on 
the upper part ; the feelers a^-e flender, and of a 
greeni.fli colour ; the head, the breaft, and the ex- 
ternal wings, are of a bright green, but fomewhat 
rough; and the belly is alfo green. The fnout 
has four joints; within it is a briftly tongue; and 
a yellow margin, or rim, furrounds the whole. 
This infe£t is comiiionly found in kitchen-gar- 
dens. 
Bug, Narrov/ V/ater, or Boat-Fly. This 
infe<5l is nearly an inch long, and the fixth of an 
inch broad. The head is blunt and yellow; the 
eyes are brown; the breaft is large, and of a yel- 
low colour, but fomewhat tranfparent; the fhield 
is black, with a glofs like velvet ; the external - 
wings are of a yellowifh grey, fpotted v/ith black 
round the edges ; the interior wings are whitifli 
and tranfparent ; the fore-feet are fliorter than thofe 
in the middle, and the hinder ones are much 
longer than either. The fnout is long, and fliarp- 
pointed; the feelers are very fnort, confifting only 
of two joints; and the belly is black and hairy. 
Bug, Compressed Water, or Boat-Fly. 
This fpecies is nearly an inch long, and fomewhat 
broader and more deprefled than the former. The 
head and legs are yellow; the breaft and the ex- 
ternal wings are brown, with many fine flender ■ 
tranfverfe ftreaks of pale yellow ; the under part 
of the body is yellowifn ; and the eyes are black. 
Bug, Grey Water, or Boat-Fly. This in- 
feA is extremely minute, being lefs by one half 
than a common loufe, and entirely of a whitifli 
grey colour. The back is depreffed, with a line 
running along the middle; the fore-legs are re- 
markably fhort; the feelers are alfo very fliort; 
but the hind-legs are long. 
There are feveral other fpecies of the Vv" ater 
Bug: the moft remarkable ofwhiclr are, the Black 
Water Bug of the Eaft Indies ; the Blaek and White 
Smaller Water Bug ; the Broader Brovm V/ ater 
Bug; and the Little Y ellowifli-ftreaked Water Bug. 
Bug, Plant, or Chermes. The fnout of this 
animal is placed on it's breaft; the hinder part of 
the belly is pointed ; there are four wings on the 
fides ; and the feet are adapted for leaping. Lin- 
naeus has enumerated eight fpecies ; namely, thofe 
of the elm, maple, beech, alder, fir, v/illow, aflij 
and nettle. Befides thefe, he mentions another, 
which is fuppofed to breed in the head of the 
ceraftes, or horned ferpent. 
Bug, Fir-Tree. This foecies is of an oblonsf 
figure, and of a whitifli colour. They have fmall 
heads; and pretty large prominent eyes of a brown 
hue, with a fmall black fpeck between them. The 
feelers are very fmall ; tliere is a fort of down near 
the tail ; and the wings are thin and whitifli. V7hen 
concealed in the leaves of the fir-tree, they make a 
prominence refembling a ftrawberry, 
Bug, Grass. This is a pretty large infe6l, con- , 
fidering it's kind. The body is a little deprefled 
and broad ; the head is very obtufe ; the breaft is 
grey, and variegated with white lines ; and the feelers 
are white, except at their tops, where they afilime a 
blackifl:! appearance. This creature pretty much
