THE BUG. 
433 
The houfe bug differs from all the reft of the genus, 
in having neither wings nor elytra. It has two final! 
brown eves, and two antennte, having each three articu- 
lations: Underneath thefe lies the crooked trunk, its in- 
ftruraent of torture, which, when the animal is in motion, 
lies inflected upon the breaft. The parts of generation 
are obvious in both fexes : they are often feen coupling 
together in the aft of procreation ; two days after which, 
the female depofits her eggs, to the number ot au hundred 
and fifty. 
Cleanlinefs is the beft antidote agamft thefe animals, as 
their hoftile attacks appear the proper punifhment of its 
negleft. Many fecret compofttions are made ufe of to 
deftroy them ; but that objeft feems rather the effeft of 
affiduity than of a cure. Mixtures have been made for 
this purpofe, of foap, verdigrife, and Scotch fnuflf, which 
are faid to be effeft ual. After having taken down the 
bed three or four different times, and waffling it with a 
folution of corrofive fublimate, they have been banifhed- 
The fmoke of peat, where that fuel is to be had, is the 
irioft efficacious of all applications, and uniformly de- 
ftroys thefe trouble Come animals wherever it is ap- 
plied. 
The field bugs have all wings, and inhabit plants as 
various as their ihape and colour. In their larva ftate 
they are very aftive, and differ but little from the per- 
feft animal, except in their wanting wings : In this ftate, 
however, as well as that of a cjhryfalid, the animal is in- 
capable of propagating its kind. After the lall transfor- 
mation, the wings unfold ; and the impregnated female 
lays her eggs commonly ranged one belide another, upon, 
ihe leaf of a plant.
