644 MR. P. D. MONTAGUE ON THE 
may be more representative than might at first be supposed. In 
any case the number of species inhabiting the islands is likely to 
be small. 
LEPIDOPTERA. 
Rhopalocera. 
Of butterflies frequenting the Monte Bello Islands there are 
eight species, the majority of which are common and _ widely 
distributed forms, though one, possibly two, of the Lycnids are 
distinct island forms. ‘lhe specimens have been compared with 
forms in the British Museum. 
1. BeLenors TevronrA Fabr. 
Belenois java Waterhouse, Cat. Rhop. of Australia, no, 1 
memoir, N.S.W. Naturalists’ Club, 1903. 
A well-known Austro- Malayan species, very abundant. 
2. PRECIS VELLIDA (Fabr.). 
One example of this widely-distributed and rather variable 
butterfly. 
3. VANESSA KERSHAWI McCoy. 
Another wideily-distributed form, the Australian representative 
of the familiar V. cardui. In the Monte Bello examples, the 
fifth (anterior) spot on the under surface of the hind wing is much 
reduced or absent. Though in this respect the Monte Bello series 
is uniform, yet these spots are generally somewhat variable, and 
no systematic distinction can be made. 
4. Danats curysippus Linn., form petilia (Stoll). 
An Austro-Malayan form, not uncommon on Hermite. 
5. NEoLuciA sERPENTATA H.-Sch. 
The Monte Bello series is again very uniform, and differ from 
most examples in having only one ocellus at the hind margin of 
the lower surface of the hind wing. The general coloration 
of the lower surface is brighter than in specimens from East and 
South Australia, and less bright and distinct than in specimens 
from Port Darwin and the tropical North. It is identical with 
specimens from Wallaby Island in the British Museum collection, 
and is possibly an island form. Very common over the whole 
group. 
6. NAcADUBA BIOCELLATA Felder. 
This butterfly extends over Western Australia, being parti- 
cularly abundant on the islands off the north-west coast. ‘The sets 
obtained on Hermite, Long and Trimouille Islands are identical 
with examples from Queen’s Islet, N.W.A. The species was very 
abundant from June to the end of July, frequenting the flowers 
of Myoporum.
