38. Genus: Ctenane Swinh. 
Proboscis fully developed, palpi porrect, extending as long as the head, 2nd joint thickly scaled; 
antennae doubly combed, the apical third ciliated. Hindleg with 2 pairs of spurs; forewings short and broad, 
vein 2 strongly curved from the cell-angle, 3 from before the angle, 4 and 5 from the angle; 6 rises below the 
upper angle, 7, 8, 9 and 10 petioled, 10 branching off behind 7; 11 from the cell, oblique. On the hindwing 3 is 
petioled with 4, 5 rises far above the angle, 6 petioled with 7, 8 from the middle of the cell. 
C. labuana Swinh. <3 greyish-white, tinted brown, palpi black except the apices. Eorewings greyish- labumm. 
white, strewn with brown and blackish, below the costa black dots near the base and before the middle and 
above vein 1. Through the middle of the wing runs a diffuse, dark brown band narrowed in the middle, but 
broader at the costa and proximal margin; a postmedian, badly defined line runs obliquely from the costa to 
vein 4, then it is in-curved, with black dots below the costa and above vein 2; distal area washed over with 
brown except at the apex, with traces of a curved marginal line. Hindwings quite pale brown. Half an inch. 
Labuan, Borneo. 
39. Genus: Grraptasura Hmps. 
Differs from the genus Asura by the 2nd subcostal and 1st radial anastomosing on the hindwing; it 
thereby also approximates very much the genus Zygaenosia from which it differs by the middle radial vein 
rising from above the cell-angle. The other mark of distinction from Zygaenosia stated by Hampson: the 3rd 
subcostal vein rising nearer to the margin than to the 5th, does not stand the test, since the conditions are 
variable in the latter genus. 
G. bitincta Rothsch. S'- antennae brown, thorax golden maize-coloured; abdomen greyish or yellow, litinda. 
Forewings golden maize-coloured. Hindwings buff. Length of forewings: 8 x / 2 mm. Little Key. 
G. mediofascia Rothsch. <$ antennae brown, head and thorax orange, abdomen buff. Forewing mediojasda. 
maize-coloured, at the basal three fifths of vein 1 orange; a postmedian band from the costa along the median 
incurved, a bow-shaped stripe above vein 1 and the fringes are very light aniline-colourecl reddish-brown. Hincl- 
wing creamy yellow. The $ has semi-diaphanous buff forewings. 
G. polygrapha Fldr. (27 . . .) has orange-yellow forewings with very complicated black markings; polygrapha. 
costal margin towards the base black; in the basal area there is an iriegular series of small black spots, behind 
it is a strongly curved, double, anterior transverse line turning at the proximal margin almost to the base; 
in the middle it is connected with a rather straight, double median line; a black discal dot followed by a curved, 
double posterior .transverse line; the distal one of the two lines sends teeth on the 1st and 3rd radial towards 
the margin; in the marginal area a dentate line; the apex of the costal margin with fringes black, with 
small carmine spots. Hindwing orange with a broad black marginal band and blackish dusting in the cell and 
at the proximal margin. Celebes. 
40. Genus: Tliumata Wkr. 
Only one Indo-Australian, small species occurring also in Africa with a stunted proboscis. Palpi porrect, 
short, not reaching beyond the coarsely haired forehead. S antennae doubly combed. On the forewing the 
venation does not exhibit any peculiarities, on the hindwing R 3 and M 1 are petioled, as well as SC 2 and R 1 . 
T. fuscescens Wkr. (17 c) has greyish-brown wings with very feebly indicated, blackish markings, fuscescens. 
an anterior transverse line which is distally angled on the submedian fold, a black discal dot, before the apex 
a brownish spot and before the margin short black vein-streaks, that on the middle radial vein being placed 
farther towards the margin. Assam, Ceylon, Borneo, Java, Queensland. 
41. Genus: Xautlietis Hmps. 
The only Indo-Australian species has rather long-stretched wings, a well developed proboscis, erect, 
though short palpi, and in the $ shortly serrated antennae. On the forewing the two lower subcostal veins are 
petioled, whereas the 3rd subcostal vein is absent; the two upper ones rise separately from the cell; the hindwing 
shows the same venation as the preceding genus.
