70. Morocosma polybapta, sp. n. 
Allied to M. margaritaria of Cramer (Lederer, Tafel xiv. 
fig. 7), but with the hyaline tapering bands of the primaries 
reduced to much smaller triangular costal patches ; the secon- 
daries also with a submarginal triangular silver spot beyond 
the amethyst-centred orange discal band of the secondaries: 
the longitudinal thoracic stripes pale metallic bronze-brown. 
Expanse of wings 34 millim. 
Duke-of-York Island. 
71. Margaronia plumifera, sp. n. 
Wings rather narrow and elongated ; snow-white, opaline 
and semihyaline; the veins testaceous: primaries with testa- 
ceous costal border; costal vein, a small spot at the end of the 
cell, and a marginal series black: secondaries with two mar- 
ginal black spots at apex: body silky pearly white; head 
metallic golden with the vertex white ; antennze white above, 
testaceous below; palpi with the upper half glistening metallic 
silver, the lower half white; proboscis silvery white at the 
base, otherwise testaceous ; tibiz and tarsi of anterior legs 
dusky above: at the base of the primaries is a small pouch 
containing a very long plumose pencil of testaceous hairs, 
which, when fully exserted, curl upwards and forwards in 
front of the costal margin to the middle of the wing. Ex- 
panse of wings 38 millim. 
New Britain. 
Nearest to MZ. conchylalis, but almost sufficiently peculiar to 
form the type of a distinct genus. 
The collection contains a Hoterodes from Duke-ot- York 
Island which seems to be the same as A. ausonialis of Tro- 
pical America. 
72. Hoterodes regalis, sp. n. 
Dark grey, the primaries shot with emerald-green to the 
middle and with purple from the middle to the outer margin 
an opaline-white ovoid spot a little beyond the end of the 
cell; secondaries greenish at base, otherwise shot with purple ; 
fringes of all the wings greenish bronze-colour : body shining 
bronzy grey. Under surface pale bronzy greenish grey; 
wings shot with purple towards the centre; white spot of 
primaries less oval than above; lower half of palpi, collar 
tibize, and tarsi pearly white. Hxpanse of wings 36 millim. ; 
3 ¢, New Britain. :
