lines; at the distal margin a deep brown line with lighter fringes; the hair-tuft in the cell yellow. Under 
surface hued with yellow; before the distal margin a dark brown band being broader on the forewing. Head 
and palpi brown. 1 from Mt. Poeh (Sarawak), distinctly separated from semibrevis (48 f). 
A. fulvilauta sp. nov. (48 f). Forewing yellowish ochreous, in some places with a pale reddish-yellow fulvilauta. 
hue; a yellowish-red median line bends round the cell, obliquely proximad to the hind-margin before its centre, 
behind it a pale yellowish-red band; subterminal line curved, marked by deep brown internerval spots; marginal 
area pale reddish-yellow; in the spaces between them a few small dark marginal spots; a row of large light 
dents touches the margin. Hinclwing with a proximal and subterminal line being marked at the hind-margin; 
at the distal margin a row of brown spots; cellular spot pale yellow. Beneath the fore wing is yellowish, at 
both the ends of the discocellular one dark dot each, and a postmedian brown band of small crescents, 
which however is only visible above the median. Head brown. 1 $ from Mt. Wuchi (Hainan), May 1903. As 
large as semibrevis (48 f), but much lighter. 
18. Genus: Gogana Wkr. 
Proboscis present; palpi feeble, upturned; antennae smooth and thickened, with appressed dents. 
Costal margin of forewing at the base gibbous, distal margin curved, in the centre ventricous; hindwing with 
a rounded distal margin, as much as one can see, in the $ as large as in the $. The <$ hindwing exhibits above 
in the cell a depression containing a hair-tuft. Type: G. specularis Wkr. 
G. specularis Wkr. Forewing violettish-grey with a greenish tint, with few, indistinct darker lines; specularis. 
a distal band being flawed and interrupted, composed of 5 contiguous subhyaline spots, is bordered with dark 
brown; a sub marginal line of whitish spots, edged with dark; at the distal margin a dark line; fringes white 
speckled with brown. Hindwing with a feebly light, dark-edged median band; otherwise like the forewing. 
Hindwing of as large as that of the §, the neuration is apparently normal.

19. Genus: Streptoperas Hmps. 
Proboscis present; palpi delicate, obliquely rising; antennae (of the $) thickened and flat with closely 
appressed dents; middle tibiae with one pair of spurs, hind tibiae with two pairs; fore wing broad, the costa 
curved; apex fine and obtusely produced, distal margin curved; hindwing with a rectangular apex, distal margin 
straight as far as vein 3, where it is sharply dentate, and then excised as far as the anal angle. In the fore wing 
vein 3 rises far before the cell-end, 6 from the very much depressed end of the subcostal; 7, 8, 9 forked, 
10, 11 forked, 10 strongly anastomosing with 8, 9 and forming an areola, 7 and 11 from this areola; in the 
hindwing 3 rises far before the cell-end, 6 and 7 separate at the centre of the cell, 7 for a short distance 
nears 8. Type: S. luteata Hmps. 
S. luteata Hmps. (48 g). Forewing yellowish, densely spotted greyish yellowish-red and in some luteata. 
places coated with that colour; the lines are darker, the subbasal and proximal lines extending obliquely and 
sharply from the costa to the subcostal, then indistinct, the proximal line in the cell sharply angled and 
obliquely proximad, the distal line oblique to vein 7, then angular and obliquely proximad, behind it a thick 
straight line obliquely from the apex, in front of this line below vein 4 a yellowish spot traversed by 3 or 4 
dentate crescentiform lines of small brown scales; the space close at the distal line remains yellow; a sub- 
marginal brown dentate chain of small crescents, accompanied below vein 5 by yellow scales which entirely 
fill up the anal region; at both the ends of the discocellular one black dot each surrounded by yellow, the 
upper dot being larger and irregular; hindwing with a yellow subbasal band; a yellow band with 2 chains 
of brown crescents, and a broad brownish antemedian band which is bordered with a double violet median 
line; the spots at the cell-end are ring-shaped, the marginal half of the wing crossed by 3 or 4 undulating brown 
lines. Subterminal line irregularly notched, behind it between the dent and the anal angle powdered with 
blackish-brown. The type, a 8, originates from North-East Bengal; specimens in the Tring Museum from 
the Kina Balu and from S. Celebes, likewise both the latter without brown powdering on the forewing. 
S. crenelata Swh. Smaller than luteata (48 g), forewing light pinkish brown, the lines as in luteata , crenelata. 
but the light hyaline area below vein 2 extends from the distal line to the proximal line. Hindwing darker 
brown with a yellow-spotted proximal line and 3 yellow spots in the distal line, 1 in the cliscal fold, the other 
two at the submedian; marginal area red-brown with a dark subterminal crescentiform line. Described 
from a single <$ from Pulo-Laut (North Borneo). It may be the 8 of luteata, since all the 3 specimens known 
of it are 
20. Genus: Pliyllopteryx Snell. 
Proboscis present; palpi stout, smoothly scaled, porrect; antennae in both sexes quite plain; middle 
tibiae with 1 pair of spurs, hind tibiae with 2 pans. Fore wing long and narrow with a straight costal margin
