S. baibarana Mats. $ is separated from postornata (88 i) by the more slanting oblique band terminating baibarana. 
farther beyond the centre of the costal margin, the postmedian line being almost straight, terminating a little 
before the tornus, distally bordered by a lustrous coppery wedge-shaped spot. Margin and apex at the costal 
margin greyish. Expanse of wings: 56 mm. Formosa, in June. 
S. neutra Swh. Body dark brown, head, collar and anterior part of thorax golden yellow. Forewing neutra. 
dark golden brown, with a black straight, distally curved antemedian band and a submarginal twice dentated 
transverse band broadly bordered inside with gold, with a brown cell-end spot and inner margin. Hindwing 
pale pinkish-brown. All the fringes pinkish-grey, those at the tornus longer and black. Abdomen with a large 
yellow basal spot and a golden spot before the end. Expanse of the wings: 26 mm. Rangoon, in May. [Wile- 
man ranges this species as a synonym under Natada conjuncta, but the colour of the abdomen is different.] 
S. tamsi sp. n. (88 k). Body whitish, edge of collar and legs with a coppery gloss. Forewing lustrous tamsi. 
light coppery, only the costal margin remains white, dusted with some black atoms. The apical part is darkened 
by greyish, but still with a slight shine. The remaining triangular golden coppery spot is crossed by a straight 
dark coppery transverse line extending from the tornus towards % of the costal margin which, however, it 
does not reach, since it does not extend beyond the coppery area; distally to it the copper colour appears to be 
roughened. Hindwing ochre with darker fringe. Expanse of wings: 30 mm. Borneo. type of the beautiful 
and conspicuous species from Sarawak (British Museum). 
75. Genus: Praesetora gen. nov. 
Separated from Setora and Thosea by vein 10 of the fore wing arising somewhat separated from the 
stalk of 7—9, the anterior angle of the cell projecting a little, vein 11 being straight. Hindwing: 6 + 7 stalked, 
8 anastomoses with the anterior edge of the cell near the base, posterior angle of cell projecting little. Antenna 
of J long bipectinate in the basal half, then suddenly bare. Hind tibia with 2 pair of spurs. 
Type of genus: P. divergens Mr. 
P. divergens Mr. (= divaricata Mr.). Red-brown, rarely more greyish-brown. An almost straight dark divergens. 
transverse line extends from % of the costal margin of the forewing to the tornus, another line somewhat convex 
towards the tornus extends to the inner margin before the middle. Expanse of wings: 30—36 mm. North 
India. — The Malay race: albitermina subsp. nov. (88 i) is always smaller, the interior transverse line is inclined albi- 
to disappear, the exterior one is distally bordered with whitish, the whole marginal area distally to it is often termxna. 
dusted with whitish. Expanse of wings: 22—30 mm. Malacca to Borneo. <J, $ types from Ivina-Balu (Berlin 
State Museum). — kwangtungensis subsp. nov. is more different; the colouring is light brown, with hardly any kwang- 
red tinge, the transverse stripes are distally bordered only narrowly with whitish. Expanse of wings: up to tungensts. 
26 mm. South China, in 2 generations at the beginning of June and at the end of August. <$ type taken by 
Dr. Mell on the lantern near Lung-tao-shan (Berlin State Museum). 
76. Genus: Tliosea Wkr. (incl. Autocopa Meyr.) 
It corresponds with the preceding genera in vein 8 of the hind wing anastomosing with the anterior edge 
of the cell near the base. Forewing: 7—9 stalked, 10 together with this stalk from the same basis, or stalked, 
rarely separated. The posterior angle of the cell projects a little towards the margin, that of the hindwing but 
little. The <$ antenna shows short double pectinations gradually shortening towards the apex. 
A group of rather monotonously coloured species. I had no access to the description of Tli. bicolor 
Shir, from Formosa. 
Th. aperiens Wkr. (88 k). Body and wings olive brown, basal half of forewing sometimes darker, aperiens. 
fore wing with two posteriorly very divergent pale transverse lines. Vein 10 of fore wing separated from 7—9. 
Expanse of wings: 26—30 mm. — Larva green above, with 3 rows of purple brown spots and 4 rows of spined 
appendages, purple brown beneath. India, Ceylon. 
Th. magna sp. n. (88 k). Forewing light grey, with a dark grey narrow transverse line from the costal magna. 
margin before the apex almost parallel to the distal margin to the inner margin. Beyond it, between veins 2 
and 5, indistinct dark dusting. Cell-end spot black, remarkably large. A narrow blackish shadowy band from 
the origin of vein 2, projecting below vein 2 in a dent towards the distal margin, to y 3 of the inner margin. Hind¬ 
wing dark grey. Expanse of wings: 45 mm. Khasis. type in the Tring Museum. 
Th. sinensis Wkr. ’(= taiwana Shiraki) (88 k). Forewing bluish brownish-grey to whitish-grey, scantily sinensis. 
dusted with blackish, with a brown almost straight transverse stripe which is but little posteriorly divergent 
with the margin, extending from the costal margin before the apex to the inner margin before the middle, cross-
