Sect. II. Antennae of cf subserrate with sessile curved fascicles of cilia. 
T. dinawa Beth.-Baker (5 c). Forewing white, thickly irrorated with pale grey green scales with a few dinawa. 
reddish ones towards base; inner line grey green, double, obscurely waved, marked on costa by a small 
black dot; outer line also double, lunulate-dentate, black, excurved in upper half of wing, rising from a black 
costal spot; median shade marked on costa by a large triangular dark green blotch, the inner half darkest, 
reaching into cell and partially obscuring the round orbicular stigma; reniform very indistinct, pale with 
indefinite grey green outline; at base of submedian fold a velvety black wedge-shaped streak, continued more 
thickly from median shade to submarginal line with the intercepted black lunules of outer line thick and 
prominent on its upper edge; submarginal line, close to termen, lunulate-dentate, whitish, preceded by 
a similar grey green shade; fringe green and white; hindwing pale dull luteous, the apical half reddish 
fuscous in cf, wholly reddish in ?, with indistinct dark waved outer line; fringe mottled, pale and reddish 
fuscous; head and thorax white thickly speckled with green; the dorsum darker; underside of both wings 
with the coloration dull deep vinous. Recorded only from British New Guinea. 
T. ekeikei Beth.-Baker (5a). Forewing white varied with yellowish green; inner and outer lines very elceikei. 
obscure, double, greenish and wavy, the outer sometimes with black striae on outer edge; median band vertical, 
greenish, expanding on costa into a blackish green triangular patch, partially, as in clinawa , obliterating the 
orbicular stigma; the reniform greenish with white ring; submarginal line indistinct; a row of black and white 
terminal lunules; at base of submedian fold a bright red hmule in cf, a black one in ?; a thick black streak 
in it from median band to submarginal line with two rounded prominences on its upper edge; hindwing luteous, 
with apical half reddish fuscous, as in dinawa, in cf, wholly reddish fuscous in ?. British New Guinea. 
T. psorallina Lower (5d). Forewing white thickly dusted and tinged with green; the markings as in psorallina. 
ekeikei ; the orbicular and reniform better defined, the former partially lost in the double green median shade 
which is blacker at costa; submedian fold with a red lunule in the cf and a black one in ? near base, and 
a blackish green streak from median shade to submarginal line; the terminal lunules green and white; fringe 
white, with slight black lunules at middle and tips; hindwing whitish in cf, rufous tinged in ?, the apical 
half deeper rufous in both. Kuranda, Queensland, N. Australia. 
T. kebeae Beth.-Baker (5c). Forewing olive grey green with an undertone of bluish white; the costa kebeae. 
cream colour between the black marks; a black triangle near base; inner line very indistinct, double, marked 
by a black spot on costa and two on inner margin, waved and green between; outer line double, whitish 
marked by a black spot on costa, a black double lunule beyond cell, black confluent lunules on submedian fold, 
and streaks on inner margin; median shade containing 3 black lines at costa, obscuring the orbicular, and black 
lunules in submedian fold: reniform stigma whitish with interrupted black external edge; at base of submedian, 
fold a strong black streak with upward projections near base and at extremity, reappearing as a thicker streak 
between median shade and outer line, the lunules of which it intercepts and thickens above; the space between 
the third median lunule and the double lunule of outer line occupied by a bright white spot; submarginal line 
double, whitish, starting from a large double black costal blotch; fringe with double black lunules between, green 
and white beyond the veins; the space between inner and median lines is sometimes strongly bluish white; 
hindwing whitish, the terminal area, especially at apex, rufous beyond an indistinct waved outer line; fringe mottled, 
dark grey and white; — in ab. rufilota ab. nov. (5d) the green forewing is washed with rufous. British New Guinea. 
This species shows a strongly developed double metathoracic tuft and tufts on dorsal segments of abdomen. 
Sect. III. Antennae of ? lamellate, simple. 
T. melaleuca limps. (= kebeae Beth.-Baker) (Tarache nec Diphtera). (5d). Forewing white; no distinct melaleuca. 
lines; the markings all black, forming spots and blotches along the margins; a black wedge-shaped mark at 
base below cell, with a small spot on costa above it; a larger blotch at 1 / 3 and a triangular one at x /o reaching 
across cell, followed by two smaller costal spots; a broad bar reaching vein 4 and a round spot at apex; 
beneath it on termen a small spot and a streak above vein 4 touching the broad bar from costa; on inner 
margin a triangular blotch before middle and an oblong oblique blotch at anal angle reaching vein 3; hind- 
wing white in inner marginal half, blackish fuscous in apical half, restricted, in the cf, to an apical blotch 
only; head and thorax white marked with black; abdomen fuscous. The type, a ?, from Mt. Kebea, British 
New Guinea; received in some numbers from Dutch New Guinea. 
T. argentea Warr. (5d). Forewing silvery white, with four black patches; a narrow one at base; a argentea. 
truncated conical patch at middle of costa, a triangular one before apex, and another at middle of inner 
margin; a dark smudge on termen from 3 to 5; fringe mottled black and white; hinclwing fuscous grey, 
paler towards base and inner margin; head and shoulders white, thorax black; metathoracic tuft white and 
dorsum shining grey. British New Guinea. Quite a small species, close to the preceding, melaleuca Limps,
