third segment of palpi shorter, abdominal segment 1 above with a tuft of scales. — Australia, New Guinea 
and Tenimber; 3 species. 
R. maculosa Roths. (4 b). Head and thorax spotted with yellow, or the markings of the meso- and meta- maculosa. 
notum white, abdomen ringed with yellow and black. Markings of wings white or yellowish; forewing with 
a spot in centre of the hind margin, a constricted discal band, a spot near the apex and another near the 
hind angle, and a variable number of dots on the disc, in the cell and before the hind margin. Hindwing 
with a large yellow patch in the basal half and a spot before the anal angle; fringes chequered. Larva 
(inflated specimens) yellowish, with numerous thin brown transverse lines, in the centre of each segment a belt 
of black dots which bear each a long pale hair; thoracical legs and a lateral patch at the abdominal legs glossy 
black; head reddish; Pupa obtuse at the anal end, the last segment sidcate above with the sides widened in 
keel-shape. — Queensland. 
R. placodes Lower (4 c), which I have not seen, is probably only a local form of the previous. The pale placodes. 
dots of the forewing are nearly all absent, and the fringes of the hindwing are for the greater part dark. — 
Tasmania. 
R. vagata Walk. (= kuehni Roths.) (4 b). Abdomen entirely yellow beneath, without black belts. Band vagata. 
of forewing longer, more oblique, more tapering behind, and the patch of the hindwing larger than in maculosa. 
—- North-West Australia, Tenimber, Dammer, Letti, Sumba and British New Guinea. 
24. Genus: Idalima Turn. 
Likewise similar to Argyrolepidia, but the antennae distinctly compressed distally, in the the mi¬ 
nute cilia longer and the segments somewhat separate beneath, the antenna of this sex appearing feebly serrate 
in a lateral view. — Australia.

a) Abdomen without a tuft of hair dorsally at the base. 
I. affinis Bdv. (= vindex Butl.) (4 c). Brown-black, middle of mid tibia and apex of abdomen yellow, affinis. 
abdomen with thin white belts above and broad ones beneath. Fore wing with numerous yellowish white dots 
in the basal half, a similarly coloured discal band, which is constricted or separated into 2 spots; before 
the distal margin a row of small dots. Hindwing with white fringes which are more or less spotted with black, 
this wing bearing moreover bluish white dots on the underside. —- New-South-Wales; Queensland. 
I. metasticta Hamps. (4c). Similar to the previous, but the hindwing with white dots on the upper- metasticla. 
side, and the discal band of the fore wing reduced to 3 small spots. Abdomen entirely white beneath. — 
North-West Australia. 
I. hemiphragma Lower (4c). Larger than the two preceding species. Reddish brown; abdomen hemi- 
yellow at the apex, banded with yellow beneath; discal band of forewing narrow, distally once and proxi- phragma. 
mally twice incurved; hindwing with a white median lunule which extends from radial 1 to the submedian 
fold, but does not enter the cell. -—- Perth, West Australia. 
I. diversa Walk. (4 b). Head, thorax, legs and anal half of abdomen orange for the greater part diversa. 
a broad band on the hindwing of the same colour. Markings of forewing pale yellow, viz., a constricted dis¬ 
cal band, a median row of 3 spots, and a large subbasal patch, before the distal margin a row of minute dots; 
fringes of both wings spotted with yellow. -— North-West Australia; the specimens before me (2 3 $$) 
obtained in January and February. 
b) Abdomen with a tuft of hair dorsally at the base. 
I. ardescens Butl. (3 b). Head and thorax with yellowish white markings; a dorsal tuft of hair at the ardescens. 
base of the abdomen, the apex of the abdomen, the coxae and the femora and tibiae of the mid and hind 
legs orange. Forewing with a purplish red longitudinal smear in front of the submeclian; markings similar 
to those of diversa but paler, before the distal margin two rows of dots, in the cell a blue spot and another 
on the discocellulars. Hindwing black, the fringes checkered with white. — North-West Australia, Queensland. 
I. subaspersa Walk. (= monophyes Turn.) (4 c). Black, breast and coxae with grey hair, abdomen subaspersa. 
with yellow belts above (and at the sides) and white ones beneath. Wings blackish brown; forewing with 
a straight white band from the costal margin to the hind angle. — New-South-Wales and Queensland. 
I. fluitans LS&m. Not known to me in nature; probably = subaspersa. Expanse 35 mm. Abdominal fluilans. 
segments edged with golden yellow, tip of last segment black. Forewing brownish black with an undulate 
white band from 3 /s of costa to the hind angle, this band projecting in angle-shape proximally in the centre 
and also distally at 4 /s. Hindwing black, fringes also black shaded with grey. — Brisbane, South Queensland,
