(With 2 textfigures).
The Leyden Museum of Natural History received a small
number of Pieridae from the islands Pulu Babi and Si-
malur, collected by Mr. Edw. Jacobson. Mentioning eight
species only, I call attention to the importance of this small and three collection, because two species prooved to be new
varieties. other ones were represented by most interesting

Pulu Babi is with a dense, a coral-islet, totally overgrown by people little visited forest.
The following is an enumeration of the species received, with description of the novelties.

be which I think to specific. It is a pity that again only
one specimen has been collected.
As far as I could see with a loupe without cutting off
the genitalia, the external form is different, the valvae
being more rectangular. The two bushes of hairs are planted

This species ought to be inserted betweenA. lucasi Wall, and A. leptis Feld., both from Java.

first doubtful whether we had to do with to me, a variety
of aspasia or with a new species. The two female speci-

quite different from those of aspasia.

This species ought to be placed between H. aspasia Stoll

This is of new species great importance to the geogra-
phical distribution of the aspasia-like butterflies. The real
aspasia is known from the Philippines, Moluccas and from
Waigeu. On Java aspasia is replaced by H. judith F.;
on Bali, Loinbok, Flores, Sumbawa and Sumba we find
H. naomi Wall. Mr. Snellen described a species from the
H. which smaller than but Kangean-islands, bathseba, is vaga, i

species from Celebes. From the island Nias we know H. selma Weym., which resembles H. judith F.

varieties of Pulu Babi.
