490 On new Species of Butterflies and Moths. 
from those from Fergusson Island, which seem to be identical 
with a long series I have from different parts of British New 
Guinea. The yellow basal space, though more extensive than 
it is in the Indian form falsalis, is not nearly as extensive 
asitisin typical procopia ; its outer edge on the hind wing is 
angled, whereas in procopia it is rounded, and the yellow 
streak on vein 2 of the fore wing in the purplish outer half 
is broader and prominent. When the genitalia of these forms 
come to be examined, I feel sure it will prove their distinctive 
differences, as it has done in so many similar cases in the 
Rhopalocera. Procopia is also the largest form of the three, 
the expanse of its wings measuring from 1,%—2 inches. 
Expanse of wings, ¢ 2, 1,8 inch. 
Hab. British New Guinea. 
MaArGARroniine=. 
Margaronia pallidalis, nov. 
3 ¢. Palpi chestnut-colour, its underside pure white ; 
head and collar chestnut, body and legs white, fore tibize with 
chestnut bands: wings pure glistening white, fore wing with 
a deep costal chestnut band, inwardly marked by a_ black 
line, broken in places, with a black spot above the upper end 
of the cell: hind wing with a black spot at the end of the 
cell ; both wings with black, lunular, marginal spots; cilia 
tinged with ochreous. 
Expanse of wings, ¢ 2, 13 inch. 
Hab. Mt. Kebea, 3600 feet ; Ekeikei, 1500 feet ; Mafalu, 
6500 feet: British Central New Guinea. 
Margaronia silvicolalis, nov. 
S 2. Head, body, and fore wing much as in MU. stolalis, 
Guen., but the white central and diseal bands are much 
broader and the chocolate portions much paler and clearer; 
the hind wing is, however, quite differently marked, the band 
on the outer marginal area being narrow and composed of 
two narrow pale chocolate bands, lined with fine dark choco- 
late lines, the inner band being often nearly white; there is 
a little thickening of the chocolate colour at the apex. 
Expanse of wings, ¢ 2, 1,5 inch. 
Hab. Ekeikei, 1000 feet. 
A uniformly larger insect than stolalis, very nearly as large 
as agathialis, Walker, from Australia, I have three pairs, 
all from Ekeikei.
