The whole insect is of a delicate citron colour, excepting the abdomen, 
which is infuscate ; but the colour of this part is probably changed in dry 
examples. On the face *he colour becomes obscured, and below the base of 
the antenne it is blackish. On the pronotum anteriorly there is a trace of а 
black median longitudinal line, and the sides are broadly black, with black 
hairs ; the meso- and metanota have the sides broadly infuscate, bordered by а 
black line. The anterior and intermediate tibiæ have a black spot at each end 
and in the middle ; the posterior femora are somewhat infuscate, darker at 
each end, and with a trace of a black spot in the middle ; all the legs are 
clothed with citron-coloured hairs. The anterior wings have many small 
black dots, those below the radius, and two discal ones, larger than the others ; 
at the end of the first branch of the sector and the upper cubital vein, before 
the apex, is à conspicuous irregular whitish spot margined with black, and 
along the excised apical margin and on the inner margin are smaller whitish 
spots, margined with blackish internally, or with a blackish dot on each side ; 
the sector has sixteen principal branches ; the inner series of gradate nervules 
is rudimentary. The posterior wings are paler than the anterior, without 
whitish spots; and the black dots are only faintly indicated on the costal 
margin. 
A very beautiful insect, of the same form as S. incisus.

Found also in Australia without apparent specific difference. Most of the 
New Zealand examples (but not all) pertain to the variety indicated at fig. 4* 
with a large whitish costal spot in the fore wings ; but at present I see nothing 
to indicate that these form a distinct Species.

Drepanopteryx humilis, M‘Lachl, Journ. of Entom. vol. ii. p. 116, pl. vi. fig. 5.* 
Found also at Moreton Bay. The smaller size seems to indicate that this 
is not a form of D. instabilis.
