markings, or with a fuscous oval spot placed transversely over 
dorsum of each segment, or over first segment only. Mines con- 
spicuous blotches under the epidermis of the upper-surface of the 
leaves of the Native Box (Tristania conferta), and may be found 
in abundance during the greater part of the year.

GRAC. UNILINEATA, N. Sp. 
7-8 mm. Head, face, and palpi white. Antenne white at 
base, gradually deepening to fuscous. Thorax white, lateral 
margins ochreous-fuscous. Abdomen above ochreous-fuscous, 
darker posteriorly, beneath white. Legs whitish, tarsi ringed 
with blackish fuscous, anterior and middle tibize blackish-fuscous 
at apex. Forewings ochreous-fuscous; a white dorsal streak 
from base ending abruptly close to anal angle, less than half 
breadth of wing, straight-margined ; a white line along hind- 
margin from anal angle nearly to apex; apex black; a short 
longitudinal black line in disc beyond three-fourths, narrowly and 
interruptedly margined with white externally; cilia white, with a 
median black line and black subapical hook, at anal angle and 
inner margin grey. Hindwings and cilia grey. 
Brisbane ; two specimens. 
GRAC. PLEBEIA, 0. Sp. 
Head, face, and palpi white. Antenne white at base, gradu- 
ally deepening to fuscous. Thorax white, lateral margins 
ochreous-fuscous. Abdomen above ochreous-fuscous, beneath 
white. Legs whitish, tarsi ringed with fuscous, anterior and 
middle tibiz fuscous at extremities. Forewings ochreous-fuscous ; 
a white dorsal streak from base ceasing abruptly close before 
anal angle, half breadth of wing, straight margined ; along its 
margin and at its extremity the ground colour is suffused with 
dark-fuscous ; a triangular white spot on hindmargin, its apex 
reaching nearly to costa; a white streak from costa at four-fifths 
to extremity of inner-marginal line, ill-defined towards costa ; 
apical portion of costa black, interrupted by a narrow white line, 
which meets apex of hindmarginal spot; cilia white, faintly 
ochreous-whitish at apex, with a black median line and sub-apical 
hook, along inner-margin grey. Hindwings and cilia grey. 
This and the preceding two species are very similar. Z'ristanie 
may be distinguished by the indented inner-marginal line ; 
unilineata by ‘the straight inner-marginal line, less than half 
breadth of wing, and the “short longitudinal black line on disc ; 
plebera by the straight inner-marginal line, half breadth of wing, 
and the triangular hindmarginal spot. 
Brisbane ; one specimen taken by Dr. Lucas.
