pavement, during those days of early spring, when the insect myriads,
revelling in warmth and light, after their long winters durance, may be
seen madly dashing about, even in towns: on such a day, for instance,
as that whereon a certain well-known doctor among the beetles found
that living carabideous gem _Anchomenus sexpunctatus_, far from its
native _Sphagnum_ and heath, wandering on the flagstones of the W.C.
district.
But, before referring to special modes of hunting, it may be as well
to mention the _instrumenta belli_ required for the equipment of the
Coleopterist in this country. These are but few, and of the simplest
kind; indeed, in entomology, as in the gentle art of angling, it
is often the most roughly accoutred that secures the best basket.
The umbrella net, figured at p. 47, used both for beating into and
sweeping, cannot be dispensed with, and a beating stick can be cut
out of the nearest hedge. The net itself should be of fine "cheese
cloth," or some strong fabric that allows the passage of air, but not
of beetles; otherwise, if of too close a fibre, it is apt to "bag"
with the inclosed air, and reject its contents during the operation
of sweeping. The net being of course used with the right hand, its
left top edge especially bears the brunt of the attendant friction,
and gets soon worn; it is consequently advisable to have an outer
strip of stout "leather-cloth" sewn strongly over the rim there for
some little distance, extending that protection also to the right top
edge, though not for so long a space. The curved handle of the stick
should be sawn off as soon as possible; it frequently catches in the
pockets of the sweeper, causing a jerk to the net, and dispersal of its
contents. For a similar reason, the ferruled apex may well be removed.
Some collectors keep the sharp cutting edge of the spring sides of the
net uncovered, sewing the net itself to holes drilled at intervals on
the lower side of the springs: a net of this kind cuts very close,
and where there is much herbage soon gets full of fragments, taking a
long time to examine. It will be found handy if the bag of the net be
cut to a point from the front towards the handle side: this causes the
contents to gravitate to the bottom, as far as possible from the point
where the rim meets the substance swept.
