clear white ; a black dot in disc beyond |, and two in disc at f placed 
transversely — the lower rather posterior ; a series of black dots along 
hindmargin and apical | of costa ; cilia white. Hindwings white ; 
sometimes irregularly suffused with fuscous ; a row of black dots along 
hindmargin, sometimes extending into cilia ; cilia white. 
Closely allied to C. delocentra, Meyr., and subsequent research 
may show that it is merely a geographical form of this species. The 
male, however, appears very distinct, and the female may be distin- 
guished by the black second abdominal segment. A considerable 
series shows these differences to be constant. We have seen both 
sexes of C. delocentra taken by Mr. Lower in South Australia, and in 
these the forewings of the male are white. (Trans. Roy. Soc. S.A. 
1892. ) Brisbane: larvae found in the stems of several species of 
Eucalyptus. 
17. Cryptophaga epadelpha, Meyr. Meyrick. 36. Male, 
31-36 mm. (I have seen one specimen, perhaps starved, only 25 mm.); 
antennal pectinations, 4. Female, 40-48 mm. The hindwings in 
male are uniform blackish-f ucous. 
Brisbane: larvae found commonly tunnelling the stems of Tristania 
conferta (Box-tree), less commonly Tristania suaveolens (Swamp 
Mahogany), dragging in leaves for food ; moths emerge in November 
and December. This and the two following species are closely 
allied, and the larvae are also closely similar. G. epadelpha may be 
distinguished by the total absence of discal dots on the forewings ; 
C. pultencece by the more rounded apices of the forewings and the 
presence of discal dots ; the white variety of C. nubila resembles 
C. epadelpha in shape of wing, the discal dots are usually present, and 
it never has the pure snow-white tinge possessed by fresh specimens 
of the other two species. 
18. Cryptophaga pulten^ej^Zw. (Cri/ptophasapultence<£,~LeviiTL\, 
Ins. N. S. W.) Meyrick, 38. Male, 31-^3 mm.; antennal pecti- 
nations, 4. Female, 32-33 mm. 
Brisbane : bred by Mr. Illidge from larvae tunnelling the stems 
of Eugenia myrtifolia and Eugenia Smithii. Meyrick gives Pultencea 
villosa as the food plant. 
19. Crtptophaga nubila, Lucas. Proc. Linn. Soc. N.S.W. 
1893, 161. {Cryptophaga intermedia, ibid., 162.) Male, 28-33 mm. ; 
antennal pectinations 4. Females, 32-42 mm. Forewings with vein 
2 from f. Hindwings with 6 and 7 from a point. Head, face, and 
palpi white. Antennae white at base, passing into fuscous. Thorax 
white, ochreo us-whitish, or pale slate-coloured. Abdomen in male 
fuscous, segments narrowly edged with white ; in female white ; in 
both sexes second segment orange-red. Legs white, tarsi annulated 
with fuscous. Forewings oblong, costa in male very slightly, in female 
moderately arched, apex moderately rounded, hindmargin rounded, 
slightly oblique ; white, ochreous- whitish, or pale slate-coloured, fre- 
quently sparsely, sometimes densely, irrorated with dark fuscous scales; 
costal margin white ; a black dot in disc at i, and two others transversely 
placed at f , lower somewhat posterior — these are very rarely obsolete, 
but sometimes lost in the fuscous suffusion ; a row of black dots 
along hindmargin and apical | of costa, sometimes obsolete; cilia
