with dark fuscous posterior streak. Antennal ciliations very sliort. 
Tliora.x purplish-fuscous. Abdomen rather elongate, fuscous, with 
long hairs on sides. Posterior tibiae witli whitish-ochreous hairs 
beneath on basal half. Forewings elongate, rather narrow towards 
base, considerably dilated posteriorly, costa anteriorly straight, 
posteriorly gently arched, apex rounded, termen rounded, some¬ 
what oblique ; 7 and 8 stalked, 8 to termen ; dark fuscous ; basal 
f darker -with a strong purple gloss, limited by a cloudy irregularly 
waved pale greyish-ochreoustransver.se line, sometimes little marked; 
a large rounded purple-blackish apical blotch, limited by a similar 
less marked line from i of costa to dorsum before tornus, approxi¬ 
mated to first above middle but nearly ob.solete there, space between 
these two lines .somewhat irrorated with pale greyish-ochreous : 
cilia fuscous, with dark fuscous subbasal line. Hindwings fuscous, 
lighter towards apex, ba.sal half suffused with blackish-fuscous ; cilia 
fuscous, on lower half of termen whitish towards tips. 
Bali, in April; three specimens. Very near strepsizoiia 
(of which the type specimen, described as a is really 
therefore the differences are not sexual), but differs by 
white and fuscous head and palpi (yellow in strejjsizonct), 
less developed pale transverse lines, and peculiarly coloured 
hindwings (in streiosizona uniform dark fuscous), with cilia 
not white externally on upper part of termen.

5 ■ 14-15 mm. Head, thorax, and abdomen dark fuscous. 
Palpi slender, whitish-fuscous. Antennae in pubescent-ciiiated. 
Forewings triangular, costa strongly arched, apex obtuse, termen 
somewhat rounded, slightly oblique ; 7 and 8 separate, 8 to costa ; 
purple-blackish ; four thick transverse suffused whitish-fuscous 
streaks, first two straight, third curved, sharply indented towards 
dorsum, fourth from f of costa to tornus, curved, narrower ; a 
whitish-fuscous discal spot between second and third : cilia fuscous, 
basal third dark fuscous, at apex with a small w'hitish spot. 
Hindwings dark fuscous ; .straight whitish-fuscous postmedian and 
subterminal transverse streaks, former suffirsed with white on upper 
half ; cilia rather dark fuscous, base whitish, at apex suffused with 
whitish. 
Moluccas, Banda, Amboina ; in August and February, 
two specimens. This is a very interesting species, being 
the most primitive form of the genus known to me, and 
clearly showing the affinity with Simaethis and Brenthia ; 
by assuming it as the starting-point, it becomes possible
