rs, and in a quarter of an hour I had at least
fifty, and so tame that I picked them up with my fingers and
distributed them among about a dozen people who had gathered to see
what I was about. The policeman stared with open eyes and mouth, quite
satisfied that my whistle and mysterious signs in the air with my hand
had called the insects to me. Satisfied with what I had got I waved
again and bade the moths depart, and clapped the box in my pocket.
Next day I took the empty box out with me into the country. I had
several males following me, and some actually penetrated into my
pocket where was the empty box, proving that the perfume still
remained in it, though wholly imperceptible to myself."

On one occasion Mr. Bignell and a friend set out at night to find the
beautiful moth _Heliophobus hispidus_, knowing its haunts, between the
south side of the Plymouth citadel and the sea, where it is to be
found in September or October resting on the grass.

Accordingly, each furnished with a bull's-eye lantern, they visited
the locality, but it was some time before one was discerned, and that
was on a blade of grass overhanging the cliff and out of reach, a
sheer drop of twenty feet at least into the sea fretting and moaning
below. Loath to miss it, as its eyes shone like two rubies--in fact,
both saw those glistening eyes before they observed that they were in
the head of the moth--they arranged that one should lie flat on his
stomach, and that Mr. Bignell should sit down, dig the heels of his
boots into the turf, then take his friend by the legs and thrust him
over the edge of the cliff, so far as to enable him to box the moth,
whilst holding the handle of his lantern between his teeth. This was
done, and the _Heliophobus_ was secured.

But, after all, it is in the direction of parasites living upon
insects that Mr. Bignell has made the greatest research. He is the
possessor of a unique collection of the parasites that live on the
aphis, and also of the hyper-parasite which preys upon that parasite.
