below median, and towards inner-margin densely clothed with long 
hairs ; 3 and 4 short-stalked, 6 and 7 separate but closely approximated 
at base, 8 connected with cell at a point near base. 
Distinguished from Xylorycta and Lichenaula by the antenna? of 
the male. I have great pleasure in naming this genus after my friend 
Mr. li. Illidge, to whom our knowledge of this group owes so much. 
81. Illidgka epigramma, Meyr. (Cryptophaga epigramma, 
Meyrick, 31 ; Xylorycta epigramma, Lower, Proc. Roy. Soc. S.A. 
1894,91.) Male, 26-32 mm. ' Female, 30-40 mm. A very variable 
species. The variation consists partly in the greater distinctness and 
number of the transverse black lines, in particular one from costa 
at f to before anal angle, angulated in disc, is often present ; partly 
also in the presence of conspicuous squarish whitish blotches in middle 
of disc and at anal angle. A very distinct variety has a conspicuous 
longitudii al black streak from first transverse line to liindmargin. 
Brisbane : Mr. Illidge has found the larva? abundantly on the 
trunks, or larger branches, of several species of Eucalyptus, usually 
tunnelling the young w T ood on the edge of a fractured branch, or 
some other injury. Also three specimens from Charters Towers, bred 
by Mr. Dodd. These are much smaller (23-26 mm.) than the Brisbane 
types, and have paler hindwings. 
17. MYLOCERA, n.g. 
Head smooth ; ocelli absent ; tongue developed. Antenna? 
moderate, in male much thickened with scales towards base, not 
ciliated, basal joint short, without pecten. Labial palpi short, curved, 
ascending, second joint rough-scaled anteriorly, terminal joint 
less than half second, acute. Maxillary palpi very short. 
Thorax smooth. Abdomen stout. Posterior tibia? shortly rough- 
haired above, smooth beneath. Forewings with vein 2 from f, 3 from 
angle, 7 and 8 stalked, 7 to hindmargin immediately below apex, 11 
from middle. Hindwings over 1, oblong-ovate, inner-margin hairy, 
3 and 4 from a point, 5 parallel, 6 and 7 short-stalked. 
A very distinct genus, immediately distinguished by the peculiar 
antenna? of the male. 
82. Mtlocera tenebrifeea, n.sp. Male, 18 mm. Head, face, 
palpi, antenna?, thorax, and abdomen uniform glossy black. Legs 
black ; anterior and middle tarsi annulated with white. Forewings 
posteriorly dilated, costa straight, apex rounded, hindmargin straight, 
slightly oblique ; black ; sparsely irrorated with pearly-white scales ; 
cilia black with a bluish-purple lustre. Hindwings dark fuscous; 
towards base free from scales and transparent, except along veins ; 
cilia fuscous, at apex black with purplish lustre. 
A very extraordinary species in general appearance. Brisbane : 
one specimen taken by Mr. Illidge. 
18. GOMOMA, n.g. 
Head with loosely appressed scales ; ocelli absent ; tongue 
developed. Antenna? moderate, in male filiform, simple, basal joint 
moderate, without pecten. Labial palpi moderate, curved, ascending, 
second joint thickened with rough scales towards apex, terminal joint
