The 0X.BOt.

The oX-bot, EStruS bowls, is a yery
annoying insect: and. as its name i'm.
plies. it usually infests animals of the
OK species. 1t is about the same size
rs the great spotted horse bot, or rather
larger; its forehead is white, and dense
ly hairy; its thoraN is yellow in front,
black in the middle, and ash-colored
behind; its abdomen has an apez with
tawny-yellow hairs, and black fasca
in the middle, and is aSh-colored at the
base; its wing-scales are white and very
large, and its legs are black. Its eggs
are deposited either on the skin. or in
oyipoSital perforation through it: and
its larva grow beneath the skin, princi-
pally along the sides of the ox'S spine
and loins, and cause tumorS or absceSS-
es analogous TO the gals on the leaves
of willows and other trees. but often as
large as pigeon eggs. When cattle are
attacked by the fly, they frequently be-
come furious, believing with violence,
and running off at their utmost speed.

may become struck with such a terror

work in the field by this fiy, and not in

guage and the enormous incumbrance
upon their flight. The larva of the OK
bot has an oblong-oval shape; it consists
of eleven segments formed by TRAVERSE
bands which are crossed at the. sides bv
longitudinal lines: and it has, on each
side of every segment, a distinct spiracle
or ureathing-hole. A cyst or minute
cell within the substance of the SKIN of
the OK is the abode of the young larva,
and the commencement of the abscess
or tumor; this gradually enlargeS with
the growth of the larya; a secretion of
pus. occasioned by the local irritation,
supplies the insect with food; and a
minute opening on the crown of the tu-
NOR permits the insect TO place the ex-
va us III COL-
tact with the atmosphere, and after
wards, at the season of maturity, to
withdraw its whole body from the tu-
NOR. The tumors occasioned i'm the
skin of cattle by the oN-bot have long
been popularity regarded as disease
under the name of MARBLES or wormals.
Except in rare instances, however. war
bles do not affect the healthy condition
of cattle, but, on the contrary, are re-
garded by many butchers as indications
of soundness and strength, Yet hides
which have been affected with MARBLES
are irretrieyably damaged, and when
in that condition, are readily and great
ly deprecated by the tanner; the tor
lures, too, which cattle suffer at the de-
position of the eggs, are injurious to
their welfare, and sometimes occasion
considerable accidents. Either the in
insertion of red-hot knitting needle. or
squeezing it out and crushing it with
the finger and thumb, will kill the lar
