as orbicular; postmedial line almost parallel to termen, cream coloured, curved 
at 8, nearly straight and very oblique to vein 4, then curved inwaidly to vein 2, 
then curved outwardly to 1 a, then oblique to inner margin; just beyond it and 
near tornus a slight hind-marginal tuft of dark vinaceous-drab hairs and a 
broader similar tuft just before it; some da,rk and white scales beyond post- 
medial line at apex above vein 8 ; a sub-terminal series of black lunules between 
the veins from vein 1 b to 8 ; some black scaling beyond each lunule ; cilia 
chamois (xxx), tipped with white from vein 3 to apex and getting mixed with 
dark scales towards tornus. 
Hind wing: ground colour cartridge -buff (xxx), slightly tinged with pinkish- 
buff (xxix) on the veins and on inner marginal area; cilia cream-buff. 
Under side: ground colour of both wings cream-buff; the costal fascia 
of fore wing cartridge-buff; fore wing tinged with vinaceous-buff (xl), thinly 
at inner marginal area; hind wing with the costa tinged with vinaceous-buff; 
cilia somewhat darker than on upper side. 
$. Ground colour of fore wing and thorax more vivid ochraceous-orange ; 
all markings less dark, ferruginous (xiv) ; a costal ferruginous fascia, less broad 
than the corresponding white fascia of antemedial line more distinct, 
ferruginous, double and filled in with some whiter scales, incurved at discal 
fold and below 1 b ; postmedial line less distinct, more curved between 2 and 5 
and only clearly visible as far as vein 2; beyond it a white triangular macula 
at costa; sub-terminal lunules as in. <$; hind wing cartridge-buff, tinged with 
pinkish-cinnamon (xxix) ; under side of both wings deeply tinged with pinkish- 
cinnamon. Antennae simple; thoracic crest less pronounced, almost absent. 
$. var. Generally much darker, but lines and dark maculae obsolescent; 
thorax and colour of whole fore wing carob-brown (xiv) ; postmedial line very 
faint; white costal macula somewhat smaller; abdomen on upper and under 
sides cinnamon-rufous (xiv) ; hind wing on upper side and both wings on under 
side mikado-brown (xxix). This species comes close to niveiplaga Hmpsn. 
and argenteomaculata Aur. ; from the former it differs mainly in the orbicular 
and reniform being more rounded instead of elliptical, the macula below 
orbicular being large and not a mere blackish spot, the different postmedial 
line and the white macula being triangular, not wedge-shaped. From the 
latter it differs mainly in the thoracic tuft, which is quite long and produced 
even in the $ of argenteomaculata while the tuft of o’neili is short, triangular 
in the $ and almost absent in the $. 
Unfortunately of these two species only $s are known to me from descrip- 
tion and it will be interesting to know if their <^s will also have the broad 
white costal fascia.
