tized again; the bursa copula trix has a slightly 
sclerotized part and a membranous part. 
New Caledonia (Marie): Canala (Dela- 
cour), Noumea, Yoh ( Catala ) . 
This species has a wide geographical range 
extending over the Ethiopian region, the 
Indo- Australian area, and the Pacific islands 
(Carolines, Marshall, Gilbert, Ellice, Fiji, 
Samoa) to the Marquesas Islands and the 
Tuamotu Archipelago. 
The specimens from New Hebrides and 
the Loyalty Islands, indicated in my Cata- 
logue (1949), actually belong to the next 
species.

Wingspread 45-48 mm.; length of the 
anterior wings 21—23 mm. 
The head and thorax are brownish gray, 
the abdomen is gray; the legs are gray mixed 
with ochre-brown. 
The anterior wings are gray irrorated with 
black scales and have a slight bluish reflec- 
tion. Typically, a rather wide transverse band 
can be seen, which is ochre-brown at the 
basal third of the wing; interiorly it has a 
cream line; toward the exterior it is poorly 
defined and mixes with the background color; 
another ochre-brown transverse band is at 
the distal third of the wing; this band is wider 
at the costa than at the inferior edge, and it 
too is very badly defined, having lighter and 
darker parts; exterior to it is a line of black 
spots; the marginal band is a little darker 
than the background color; the margin is a 
thin black line. 
The posterior wings are ochre-brown-gray, 
with the abdominal margin, a medial band, 
and some parts along the external margin 
creamy white. 
The underside is ochre with darker distal 
parts. 
Genitalia d : The lateral dorsal parts of 
the ninth urite are narrow; the tegumen is 
indistinct and the uncus is typical with a 
small beak at the apex (Fig. 13^); the 
scaphium is present; the valvae (Fig. 13 b) 
are subrectangular with a small lengthening 
at the dorsal apex; neither the costa nor the 
sacculus is well defined; a short process 
starts from the internal surface and widens
