white or tinged with pale fuscous, iu which case a darker Hue at J can 
usually be traced. Hindwings in male dark fuscous, in female white, 
sometimes more or less suffused with fuscous ; a hindmarginal series 
of black dots ; cilia white. 
Var. Alba. — It is convenient to denote by this name the speci- 
mens with white ground-colour of forewings without fuscous irro- 
ration. 
A very variable species. I have bred a large series, and have 
obtained the most extreme examples from the same food-plant, j 
regard the white colouration as ancestral, the darker varieties as a pro- 
tective adaptation to the colours of the bark of the trees to which the 
species is attached. 
Brisbane : the larvae tunnelling the stems and dragging in for 
food the leaves of Melaleuca hucodendron (Tea- tree), Melaleuca linarii- 
folia, Callistetnon salignus, Callistemon lanceolatus, and probably other 
species of these genera ; also of Tristania suaveolens (Swamp Maho- 
gany) and Backhousia myrtifolia ; and in gardens of the Guava. The 
moths emerge in November and December. 
20. Cryptophaga ecclesiastis, Meyr. Meyrick, Proc. Linn. 
Soc. N.S.W., 1886, 1010; and op. cit. 32. Male, 30-35 mm.; 
antennal pectinations, 3 ; forewings fuscous ; hindwings dark-fuscous 
with a purple iridescence ; abdomen dark-fuscous. Female, 53-59 mm. ; 
forewings very pale whitish-grey ; hindwings similar, suffused with 
fuscous towards hindmargin. (Meyrick's type from Victoria was 
shining white.) 
This species is readily distinguished by the curious coppery- 
purple hindmarginal fascia. It is also characterised by the minute 
labial palpi. Brisbane : four specimens bred by Mr. Ulidge from 
larvae tunnelling the stems of Eucalyptus corymbosa (Bloodwood). 
21. Cryptophaga flavolineata, Walk. (Cryptolechia flavo- 
lineata, Walker, 749 ; Cryptophaga flavolineata, Meyrick, 36). Male, 
33-36 mm. ; antennal pectinations, \. Female, 39-45 mm. 
Brisbane : larvae live in stems of Banksia integrifolia, dragging 
in leaves for food. 
22. Crtptophaga spilonota, Scott. (Cryptophasa spilonota, 
Scott, Austr. Lep. 10, pi. 3.) Meyrick, 35. Male, 37 mm. ; antennal 
pectinations, -§-. Female. 41 mm. 
Darra, near Brisbane : bred by Mr. Illidge from larvae tunnelling 
the stems of Banksia integrifolia. 
2. XYLOBYCTA, Meyr. 
Antenna! ciliations of male, £ to 2. This genus differs from 
Cryptophaga only in the non-pectinated antennae of* the male. Recent 
discoveries have brought the two into very near relationship. I have 
been compelled to drop Meyrick's genus, Telecrates, which was dis- 
tinguished only by the shorter antennal ciliations, as the new species 
referable to the present genus render it no longer tenable. Meyrick 
himself anticipated that this might come to be the case (op. cit. 57).
