The latter correspond to our weevils and allied groups, and in the tropics are exceedingly numerous and varied, often swarming upon dead timber, so that I sometimes obtained fifty or sixty different kinds in a day.

My Bornean collections of this group exceeded five hundred species.
My collection of butterflies was not large; but I obtained some rare and very handsome insects, the most remarkable being the Ornithoptera Brookeana, one of the most elegant species known.

This beautiful creature has very long and pointed wings, almost resembling a sphinx moth in shape.

It is deep velvety black, with a curved band of spots of a brilliant metallic-green colour extending across the wings from tip to tip, each spot being shaped exactly like a small triangular feather, and having very much the effect of a row of the wing coverts of the Mexican trogon, laid upon black velvet.

The only other marks are a broad neck-collar of vivid crimson, and a few delicate white touches on the outer margins of the hind wings.
