porplyrinella, Lower, Proc. Roy. Soc. S.A. 1894, 91.) Male, 27-30 
mm. ; antennae slightly serrate towards extremity ; ciliations, f. 
Female, 31-35 mm. 
Brisbane : a series bred by Mr. Ulidge from larvae tunnelling the 
stems of Exocarpus cupressiformis (Native Cherry), and dragging in 
leaves for food. 
26. Xylorycta flayicosta, Lucas. {Oryptopliaga Jlavicosta, 
Lucas, Proc. Linn. Soc. JNT.S.W. 1893, 163.) Male, 26 mm. ; an- 
tennal ciliations, 1^-2. Female, 35-36 mm. Readily distinguished by 
the slate-coloured forewings with orange costal streak. 
Brisbane : larvae discovered by Mr. Illidge in the stems of several 
species of Eucalyptus. 
Var. pallida. — Mr. Dodd has brought a male and female specimen 
from Charters Towers with whitish hindwings, forewings rather paler 
than in Brisbane types, with broader orange costal streak, and more 
black dots on hindmargin. 
27. Xylorycta molybdina, n.sp. Female, 22-29 mm. Head, 
face, palpi, and antennas white. Thorax pale slate-colour. Abdomen 
grey. Legs whitish. Forewings oblong, dilated posteriorly, costa 
slightly arched, apex round-pointed, hindmargin obliquely rounded ; 
pale slate-colour ; a white streak along costal edge not reaching 
apex ; cilia pale slate-colour. Hindwings grey, paler towards base ; 
cilia grey. 
Brisbane : several female specimens bred from larvae found in the 
stems of Melaleuca leucadendron (Tea-tree). 
28. Xylorycta neomorpha, n.sp. Male, 25 mm. Female, 
34 mm. Antennal ciliations in male, 2. Labial palpi very short, not 
reaching base of antennae, terminal joint minute. Head, face, and 
palpi white. Antennae whitish. Thorax white or whitish-grey. 
Abdomen fuscous. Legs reddish, posterior tibiae white. Forewings 
posteriorly dilated, costa gently arched, apex rather acute, hindmargin 
very obliquely rounded ; whitish-grey ; a pale-orange line along costa 
(in female specimen absent) ; a large blotch in disc, extending to 
inner margin, but not to costa, irrorated more or less densely with 
reddish-brown scales ; in this are two elongate pale-orange spots 
at -f and -| of disc ; a third similar spot on fold obliquely below first, 
sometimes obsolete ; cilia pale reddish-brown. Hindwings dark 
fuscous ; cilia pale ochreous. 
Differs from the rest of the genus by the very short labial palpi ; 
but I think it wiser to include it here, than to make a new genus. 
Charters Towers : two specimens received from Mr. Dodd. 
29. Xylorycta tapeina, n.sp. Male, 24 mm. ; antennal ciliations, \. 
Head, face, palpi, and antennae whitish. Thorax fuscous, irrorated 
with whitish scales. Abdomen ochreous-whitish. Legs whitish with 
fuscous irroration. Forewings elongate, costa gently arched, apex 
round-pointed, hindmargin obliquely rounded ; fuscous irrorated with 
white scales ; a broad white streak along whole of costa, narrowing to 
a point at base and apex ; an obscure whitish spot above middle of 
inner margin ; a dark spot in disc at f ; cilia fuscous. Hindwings and 
cilia pale-grey.
