the narrow forewing veins 2—4 are distantly separated, 5 close above the lower angle, 6 from the upper angle, 
7 directly below the apex of the broad accessory cell, 8 -f 9 on a long stalk from its apex, 10 from the centre 
of its anterior edge. In the hindwing vein 5 on % from the lower end of the cross-vein, 8 close beside the cell. 
L. aroa B.-Bak. (80 h). Tegulae dark red-brown. Thorax and forewing greyish-white, posterior half 
pale red-brown. A basal dot and traces of the interior line blackish-brown. At the cross-vein a black luniform 
edge, before it a dark streak. Besides numerous rows of dark dots. Hindwing pale brown, at the inner margin 
yellowish. <$ 40 mm. New Guinea (Aroa R.), New Pomerania, and other islands. 
L. dentilinea J . & T. (80 h). Antennae of $ above only slightly scaled. Hind tibiae with a row of hairs. 
Thorax and forewing red-brown. Distal two thirds of costal margin whitish. Reniform macula dark-edged, 
inside of it a dark spot. Both may also almost disappear in a violettish-black spot. Hindwing brown, at the 
base lighter. $ 40 mm. From the same patriae. 
98. Genus: Acidon Hmps. 
Palpi highly erected, the 3rd joint long and spoon-shaped. Antennae of $ tufted. Base of abdomen 
with hair-tufts. Forewing long and pointed. Veins 2 + 3 stalked, 6 from the upper cell-angle, 7 + 8 + 9 
stalked, 10 and 11 free. Thus quite unusual for a Notodontida. 
A. paradoxa Hmps. Forewing dark violettish-brown. Interior and median lines light, undulated. 
Exterior line marked, ending at the anal angle. Small white submarginal spots. Hindwing dark brown. 
30 mm. Bhutan, 800 m. 
99. Genus: Ilirsiatopalpfs B.-Bak. 
Palpi highly erected, long-haired. Antennae of $ long, with fine short cilia. Middle and hind tibiae 
spined. Neuration of forewing: veins 2 and 11 far towards the base, 5 close above vein 4, 6 below the upper 
cell-angle, 7 + 8 + 9 + 10 stalked. In the hindwing veins 2, 3 and 4 equidistantly separated, 5 close at 4, 
veins 6 and 7 from the upper cell-angle, 6 branching off from the centre of the cell. 
H. fasciata B.-Bak. Head and abdomen brownish-grey, thorax ochreous grey. Forewing ochreous grey 
with a dark interior line in the centre of the wing. Behind it an oblique rusty brown spot at the inner margin, 
anteriorly faded. Then an oblique paler rust-brown double median line and 2 separated dentate dark exterior 
lines. At the cell-end 2 black spots and a series before the margin. Rust-brown spots at the anal angle, at the 
centre of the distal margin, and paler ones below the apex. Hindwing pale ohreous grey, at the margin grey. 
<$ 50 mm. British New Guinea. 
100. Genus: Betashachia Mats. 
B. augustipennis Mats. This genus and species can merely be registered, as there is no figure and the description 
is written in Japanese. 
Additions. 
A number of Formosa-species have been described in the meantime by Prof. Matsamtjra, to which 
2 other forms are added. The arrangement applied by this author is also used here. 
1. Genus: Tarsolepis Btlr. (p. 607) 
T. fulgurifera Wlk. (pi. 79 a). ( Megashacliia Mats.) takamukuana Mats, is a lighter form of it. whereby 
the two streaks below the costal margin behind the centre are more conspicuous. Veins 2 and 3 are considerably 
lighter and thereby below the long silvery stripe 2 dark stripes are isolated. At the inner margin at the base 
the brightening extends to below the base of vein 2. Before the margin, above the silvery stripe, narrow dark 
triangles are more distinctly isolated than in typical fugurifera. 80—100 mm. Horisha. 
3. Genus: I>ii<lusa Wkr. (p. 608) 
D. baibarana Mats. Similar to the form synopla Swh. On the forewing the base at the costal margin 
is darker brown, behind it at the costal margin a broader white band, the following oblique main band at the 
base of vein 2 with a short branch to about 1 4 inner margin. Ground-colour greyish-white. At the margin
