ving a very strong
and ridged back-piece, which went also on either side of its leggs; about
the wings there were several joynted pieces of Armor, which seem'd
curiously and conveniently contriv'd, for the promoting and strengthning
the motion of the wings: its head was much differing from the other, being
much bigger and neater shap'd, and the horns that grew out between his eyes
on two little balls, were of a very differing shape from the tufts of the
other Gnat, these having but a few knots or joynts, and each of those but a
few, and those short and strong, brisles. The formost horns or feelers,
were like those of the former Gnat.

One of these Gnats I have suffer'd to pierce the skin of my hand, with its
_proboscis_, and thence to draw out as much blood as to fill its belly as
full as it could hold, making it appear very red and transparent; and this
without any further pain, then whilst it was sinking in its _proboscis_, as
it is also in the stinging of Fleas: a good argument, that these creatures
do not wound the skin, and suck the blood out of enmity and revenge, but
for meer necessity, and to satisfy their hunger. By what means this
creature is able to suck, we shall shew in another place.

Observ. XLVI. _Of the white featherwing'd _Moth_ or _Tinea Argentea_._

This white long wing'd Moth, which is delineated in the 30. _Scheme_;
afforded a lovely object both to the naked Eye, and through a _Microscope_:
to the Eye it appear'd a small Milk white Fly with four white Wings, the
two formost somewhat longer then the two hindermost, and the two shorter
about half an Inch long, each of which four Wings seem'd to consist of two
small long Feathers, very curiously tufted, or haired on each side, with
purely white, and exceedingly fine and small Haires, proportion'd to the
stalks or stems, out of which they grew, much like the tufts of a long
wing-feather of some Bird, and their stalks or stems were, like those,
bended backwards and downwards, as may be plainly seen by the draughts of
them in the Figure.

Observing one of these in my _Microscope_, I found, in the first place,
that all the Body, Legs, Horns and the Stalks of the Wings, were covered
over with various kinds of curious white Feathers, which did, with handling
or touching, easily rubb off and fly about, in so much that looking on my
Fingers, with which I had handled this Moth, and perceiving on them little
white
