3. Genus: Rimma Walk. 
Closely allied to the preceding genus. The thoracic crest is less strongly develojied and the antenna 
of the is not pectinate but merely subserrate and ciliate. 
R. subaurata Walk. (8a). Fuscous, with the median area of the forewing whitish, the lines punctiform, subaurata. 
with costal spots, both wings with a large cellring, which on the underside becomes a solid black spot. Underside 
yellow, with broad dark submarginal band. Queensland (type) and New South Wales. 
4. Genus: Sterictopsis Wan. 
Differs from the three previous genera in having the 1st radial vein of the hindwing, sometimes also 
that of the forewing, stalked with the last subcostal. Antenna of pectinate. Thorax and abdomen with dense 
crests. Hindtibia of dilated, with a hair-pencil. 
S. inconsequens Warr. (= ? argyraspis Lower) (8 a). Smaller and greyer than R. subaurata, the inconse- 
veins somewhat darkened, a blackish longitudinal streak on the fold proximally; discal ocellus less developed, quens. 
lines not punctiform, the antemedian very oblique. Hindwing whitish proximally, blackish distally. Underside 
not yellow. Also from Queensland. Lower’s argyraspis was from Blackwood, South Australia and his description 
does not fit this species. 
5. Genus: ArcheobalUf s Prout. 
Build robust. Face more or less protuberant. Antenna in both sexes simple. Thorax not crested. 
Abdomen with small crests. Wings, or at least the posterior, with the distal margin crenulate. Hindwing of 
the J with abdominal margin always elongate, generally very strongly so, in the first three species with the 
posterior part of the distal margin also produced. An interesting link between the genera which precede and 
those which follow, having the facies of the latter but the 2nd subcostal of the forewing arising from the cell, 
as in the former. The species are all Indo-Malayan. 
A. urapteraria is recognizable by the extreme shape of the hindwing, which is narrow and at the 3rd 
radial produced to a blunt tail; the forewing is also appreciably narrower than in viridaria. — urapteraria Walk, urapteraria. 
(5g), from Borneo-, has the distal area beneath predominantly red. — eudicheres Prout, from Mount Gedeh, eudicheres. 
Java, is smaller, slightly intermediate in shape towards the following species (or race) and has on the underside 
a black band, 3 or 4 mm in width but tapering anteriorly and posteriorly, between the orange ground-colour 
and the red borders. Similar forms occur on Nias, Penang and the Natuna Islands, an intermediate on Sumatra. 
A. aethalia sp. nov. (8 b). Expanse 49—52 mm. Eorewing with distal margin rather shorter than aefhalia. 
in viridaria ; rather deeper green, the rufous antemedian shades broader. Hindwing narrower than in viridaria, 
slightly produced at the medians, thus approximating to the shape of urapteraria ; cell-dot weak; costal region 
with broad reddish and smoky suffusion. Forewing beneath with a blackish suffusion behind the median and 
its 2nd branch; both wings with the distal area, on the contrary, red, irregularly mottled with black, rather 
variable. S. W. Sumatra: North Ivorintji Valley, 5000 feet, September to October 1921, 8 including the 
type; slopes of Mt. Ivorintji, 7000 feet, August to September, 9 collected by the Pratt brothers for Mr. 
J. J. Joicey. 
A. viridaria Moore (= subochracea Warr.) is often distinguishable from the two preceding, apart viridaria. 
from its broader wings, by having very broad blackish or black-mixed borders on both wings beneath. 
Forewing beneath, as also in urapteraria, pale behind M and M 2 . Common in Sikkim and Assam. 
A. sinapiaria Pouj., from West China, figured in Vol. 4, PI. 3 c, is probably near viridaria but is still sbiapiaria. 
unknown to me. See p. 11 of that volume. It may prove to be a $ form of ochreipicta. 
A. ochreipicta Swinh. is similar to cristata( 5 h) but more variegated, distinguished chiefly by having a conspi- ochreipicta. 
cuous ochreous antemedian spot at the hindmargin of the forewing. Underside with the submarginal bands dull, 
predominantly blackish. Venation inconstant, the 2nd subcostal of the forewing being sometimes just stalked 
with the 3rd, almost as in Neobalbis. Khasis; also from Sikkim and I think Ivulu and Upper Burma.— montana montana.
