Antals of the Transvaal Museum. 
mixed brown and deep fuscous; metathoracic tuft posteriorly black. 
Abdomefi. brownish, the sides dusted with black, the dorsal surface strongly 
mixed with black, leaving some brown belts, or at least an anterior one. 
Forewing light-brownish, the markings blackish mixed with ferruginous 
(in one example mainly ferruginous), the basal and median areas traversed 
by the usual wavy lines ; basal patch with a small outward bend in front 
of SM 2 ; median band rather broad, more ferruginous at its edges, proximal 
edge slightly wavy, forming a very gentle and regular curve, distal with 
small indentations on SC 4 and SC 5 , a slight inward curve between the 
radials, a pointed or more rounded projection about R 3 , thence slightly 
retracted and crenulated ; a narrow, more or less interrupted white line 
between this band and the next black line, then a more ferruginous shade ; 
distal area more or less strongly clouded with black on either side of the 
deeply lunulate-dentate pale sub terminal, the most prominent markings 
being an oblique line from apex, a streak distally to, but partly interrupt- 
ing, the subterminal between SC 5 and R 1 and a patch proximally to the 
subterminal between the radials ; all the veins distally to subterminal 
thickly marked with ferruginous brown ; the dark discal mark is enclosed 
in a distinct, elongate, ferruginous-brown mark ; fringe brownish, chequered 
with fuscous. Hindwing of the same ground-colour, slightly shaded with 
fuscous as far as on ill-defined postmedian line, which is chiefly emphas’zed 
by large dark vein-spots in its posterior half and by being followed, as 
on forewing, by an interrupted pale line ; subterminal line distinct only 
in posterior half of wing, where there is again some slight fuscous 
admixture. Under surface pale-brownish, both wings (especially forewmg) 
more greyish from base to a fine, moderately distinct postmedian line 
and with a conspicuous black discal spot ; forewing also with costal 
margin basally dark-marked, especially a spot about 4 mm. from base. 
Barberton, 19th December, 1910 (type). Durban (Clark), much less 
fuscous-marked, m coll. L. B. Brout. Estcourt, Natal (J. M. Hutchinson), 
in coll. British Museum. 
Larger than saturata Guen., with a more brownish hue in ground- 
colour, black apical line and other differences. Whether the <$ antennal 
structure agrees with that group (Ochyria Warr., nee Hbn.), remains 
unknown. 
Mauna ardescens, n. sp. (PL XXV, Fig. 29). 
$, 35-38 mm. Head with palpus and antenna orange-red irrorated 
with crimson ; antenna in ^ not pectinated, merely with short, very 
shortly ciliated teeth. Thorax above orange-red ; beneath white or 
whitish, anteriorly mixed with crimson. Legs white or whitish, upper 
and inner sides of foreleg almost entirely crimson, of middle leg strongly 
mixed with crimson, of hindleg less strongly spotted with the same ; £ 
hindtibia strongly and roundly swollen, with hair-pencil, hindtibia 
abbreviated, spinose. Abdomen orange-ochreous, slightly paler beneath 
except at anal end. Wings rather broader than in typical Mauna. 
Forewing with SC 2 connected with SC 3 ' 4 by a short bar (in the typical 
species this varies between a short bar and point-anastomosis) ; orange- 
red in the $ almost entirely covered over with crimson irrorating, giving
