Beetles were so scarce that a collector might fairly say there were none, as the few obscure or uninteresting species would not repay him for the search.

The only insects at all remarkable or interesting were the butterflies, which, though comparatively few in species, were sufficiently abundant, and comprised a large proportion of new or rare sorts.

The banks of the stream formed my best collecting-ground, and I daily wandered up and down its shady bed, which about a mile up became rocky and precipitous.
Here I obtained the rare and beautiful swallow-tail butterflies, Papilio aenomaus and P.liris; the males of which are quite unlike each other, and belong in fact to distinct sections of the genus, while the females are so much alike that they are undistinguishable on the wing, and to an uneducated eye equally so in the cabinet.

Several other beautiful butterflies rewarded my search in this place, among which I may especially mention the Cethosia leschenaultii, whose wings of the deepest purple are bordered with buff in such a manner as to resemble at first sight our own Camberwell beauty, although it belongs to a different genus.

The most abundant butterflies were the whites and yellows (Pieridae), several of which I had already found at Lombock and at Coupang, while others were new to me.
Early in February we made arrangements to stay for a week at a village called Baliba, situated about four miles off on the mountains, at an elevation of 2,000 feet.
