Even at the time of my visit it was most precipitous and fatiguing, yet women and children came over it daily, and men carrying heavy loads of palm sugar (of very little value).

It was along the path between the lower and the upper falls, and about the margin of the upper pool, that I found most insects.

The large semi-transparent butterfly, Idea tondana, flew lazily along by dozens, and it was here that I at length obtained an insect which I had hoped but hardly expected to meet with--the magnificent Papilio androcles, one of the largest and rarest known swallow-tailed butterflies.

During my four days' stay at the falls, I was so fortunate as to obtain six good specimens.

As this beautiful creature flies, the long white tails flicker like streamers, and when settled on the beach it carries them raised upwards, as if to preserve them from injury.
