S. biselata Hufn. (Vol. 4. pJ. 4 f) extincta Stcjr. This widely distributed race, which is noticed in Vol. 4. rriinda. 
p. 127, was described from Amurland and is chiefly Palaearctic (Japan, Corea, X. China, etc.), but is known 
from some localities in Szechuan. Less small than decidua and denudaria the species is further known by the 
densely tufted hindfemur and tibia of the <$, most of the hair pale in colour; antennal ciliation rather short. 
The extincta form differs from the name-type in lacking the dark subterminal shades. 
S. invalida Butl. (Vol. 4, pi. 3 li, as invalidaria). Range similar to that of extincta, but not yet definitely invalida. 
known from Manchuria; the type came from Japan. More brownish than biselcila. the markings rather weak: 
antennal ciliation of the <§ perhaps a little longer, outer tuft of £ hindtibia not quite so strong, femoro-tibial 
apparently longer than in biselata. — ab. lauta Warr. Lines on both wings strengthened by black vein-dots. Ionia. 
dots on fringe also stronger than in the type. — ab. (?) infuscata SternecJc. Distinguished by the presence of infnscato. 
a strong dark subterminal shade, which reaches almost to the post median line; fringe-dots sharply black. Cor¬ 
responds to typical biselata , while the name-type of invalida corresponds rather to extincta. Omihsien (W. China) 
and Pekin are the recorded localities of the form. 
S. exempta Warr. (23 d). Founded on a from Angabunga River, the <$ later brought from Biagi. e.rnnpia. 
Belongs perhaps to the same group as (gravipes (genus Argyroscelia of Warren), but is smaller, brighter and 
with other obvious differences, particularly the whitish band between median and postmedian; probably near 
elaphrodes . Midleg of the <$ simple; hindleg w ith a very large and dense femoro-tibial pencil and with further 
tufts at the end of the tibia, the tarsus cpiite short. 
S. elaphrodes Twrn. (23 d). A diminutive species, otherwise very similar to several of the foregoing, elaphrodes. 
q ciliation about as long as diameter of shaft; hindtibia moderately long, clothed above with hairs, ending in 
an apical tuft, femoro-tibial pencil long, tarsus about 1 2 - Dots on fringe at vein-ends developed. North Queens¬ 
land. 
S. elachista Turn. Near elaphrodes or still smaller (12 to 13 mm). Easily distinguished by the $ antenna, elachista. 
which has fascicles of long cilia, about 3 times diameter of shaft. Hindleg of very short, tibia longer than 
femur, slightly thickened with scales on upperside, tarsus 1 3 . Markings weak and slender; antemedian line 
wanting, only represented by a dot at % costa; postmedian arising from a similar dot at %. North Australia : 
Darwin. 
S. sublactifera Warr. (23 d). Midtibia simple, hindtibia enormously tufted; hindwing beneath, snblaetitcra 
especially in the A, with specialized glaucous-whitish scaling nearly throughout, little or no hair-scaling. Only 
known from Rossel Island. 
S. gravipes Warr. (23 e). The type of the “genus " Argyroscelia Warr.. “distinguished by the armature gravipes. 
of the hindlegs of the A ; these have a very large and dense tuft of hair from the femoro-tibial joint as long 
as the tibia itself; the tarsus and tibia are externally fringed with long hairs and internally clothed with smooth, 
very glossy silvery scaling, the end of the tibia bearing a flap-like process, which is capable of lateral expansion." 
A little larger and more greyish brown than sublactifera , postmedian straighter between the radials, dots on 
fringes (in sublactifera on terrnen), hindwing beneath less white. Biagi. 
S. bipartita Warr. (23 e). Very distinct in the conspicuous, straight red-brown median line, which on bipartita. 
the forewing touches the black cell-dot. Although the originals are 3 $$ (not “1 J 1 . 2 $£". as published) I as¬ 
sume it has similar structure to (gravipes. Angabunga River, British New Guinea. 
S. carnearia Warr. (= carneola Warr.) (23 e). This and the 3 following forms are more flesh-coloured carnearia. 
than the actiosaria group, with which they agree in general in having all the subcostals stalked considerably 
beyond the areole. Forewing somewhat broader, cell-marks not black, carnearia is a relatively rather large 
species and recognizable by the ventricose terrnen of the A hindwing. Antennal ciliation in the £ extremely 
short; hindtibia long, heavy, thickened distallv, tarsus extremely short. Described from Borneo, recorded also 
from Penang, Langkawi and Mindanao; Tring Museum has 1 A from Sangir and has recently received a long 
series from W. Bali. 
S. perspersata Warr., a $ from Oinanisa. Dutch Timor, is probably merely a local form, or even a synonym, perspersata 
of uniforms ; no further material has been received from that source. The dark irroration is perhaps denser 
than in typical uniformis and rufula. 
S. uniformis Warr. (23 e). Also founded upon a $ and. as this is in poor condition, possibly I have uniformis. 
not formed a correct conception of it. It seems to be definitely less rufous (paler greyish fleshy) than rufula 
and (equally with perspersata ) to have the lines extremely weak. Mackay, Queensland; our figured <§, from 
the same locality, perhaps confirms the colour, but is much rubbed.
