90 NATURAL HISTORY 
and railing tumours which itch intolerably. This animal (which 
we call an harveft bug) is very minute, fcarce difcernible to the 
naked eye; of a bright fcarlet colour, and of the genus of Acarus. 
They are to be met with in gardens on kidneybeans, or any 
legumens; but prevail only in the hot months of fummer. 
Warreners, as fome have alTured me, are much infefted by them 
on chalky downs; where thefe infe(5ts fwarm ft3metimes to fo 
infinite a degree as to difcolour their nets, and to give them a 
reddiih caft, while the men are fo bitten as to be thrown into 
fevers. 
There is a fmall long Ihining fly in thefe parts very troublefome 
to the houfewife, by getting into the chimnies, and laying it's 
eggs in the bacon while it is drying : thefe eggs produce 
maggots czWtd jumpers^ which, harbouring in the gammons and 
beft parts of the hogs, eat down to the bone, and make great 
wafte. This fly I fufped to be a variety of the mufea putrls of 
hinnaus: it is to be feen in the fummer in farm-kitchens on the 
bacon-racks and about the mantle-pieces, and on the ceilings. 
The infe£l that infefts turnips and many crops in the garden 
(deftroying often whole fields while in their feedling leaves) is 
an animal that wants to be better known. The country people 
here call it the turnip-jly and hlack-dolphin ; but I know it to be one 
of the coleoptera', the '* chryfomela oleracea, fait at or ia, femoribus 
*' pqftids craJJi/JJmis." In very hot fummers they abound to an 
amazing degree, and, as you walk in a field or in a garden, 
make a pattering like rain, by jumping on the leaves of the turnips 
or cabbages. 
There is an Oefirus, known in thefe parts to every ploughboy; 
which, becaufe it is omitted by Linnaus, is alfo pafled over by 
late writers ; and that is the curvicauda of old Moufetj mentioned
