1. Genus: Indarbela Fletcher. 
Palpi stunted. Antennae with two rows of pectinations as far as the apices, the pectinations of the 
being stronger than those of the $. Hind tibiae with short terminal spurs. Fore wing: veins 9 + 7 -j- 8 
on a long stalk, the others separate. Hindwing: a bar extends from % of the anterior edge of the cell to 
vein 8; veins 6 and 7 arise close together, the others more separated. — In the annnual report for 1930—31 
of an Indian Institute for the extermination of pernicious insects, a species of Indarbela is mentioned to be 
pernicious to Zizyphus jujuba, Phyllanthus emblica, Bauhinia purpurea. The imagines emerged in May. The 
name of the species is unfortunately not stated. 
I. quadrinotata Wkr. ( = abruptus Wlcr., tessellatus Mr.) (93 g). $ pale rusty brown on the body and 
fore wing, with rows of darker rusty red spots; below them more distinct spots at the cell-end and close behind 
it, as well as below the cell beginning from the base. Hind wing blackish-brown. $ (— tessellatus) greyish- 
yellow. Forewing with darker spots than the <§. The light hind wing with lighter spots which are of a much 
neater shape. 34 —50 mm. Calcutta, Ceylon. tetraomis Mr. (93 g) are $$ exhibiting a series of more in¬ 
tense spots before the margin and at the margin on the forewing. The hindwing shows larger postcellular 
and subcellular spots instead of the fine striae. One specimen from the Coll. Atkinson exhibits these spots only 
on the left hindwing, while the right hindwing show's fine striae. Calcutta, Bombay, Raipur. 
I. campbelli Hmps. (93 g). Fore wing dark red-brown with greyish-white streaks forming an interior, 
exterior, and submarginal line. Veins and submedian fold white. Some light streaks also in the cell. Hind¬ 
wing lighter brown with rows of dark spots similar to those of tetraonis. J 36 mm. Madras. The larva lives 
on Ochna squarrosa. 
1. phaga Swh. Forewing pale red-brown with dark red-brown fine striae and larger spots. Such a 
spot behind the cross-vein and some smaller ones in the cell. A prominent row of spots from the apex to 
about the centre of the inner margin. A radial whitish cloud in the submedian fold. Hindwing pale brown, 
without markings. $ 40 mm. Cherra Punji, Khasia Mts. — According to Hampson, phaga is a form of tetra¬ 
onis. Hindwing of the blackish-brown. 
I. theivora Hmps. Fore wing dark brown, red-brown at the costal margin, in the cell and at vein 1. 
Traces of a black spot at the cross-vein, the marginal area finely striated dark. Hindwing very dark, without 
markings. The $ is greyer with many dark striae on the forewing. 18—22 mm. Assam, Silhet. Larva on 
Tea and Mango. 
I. discipuncta Wilem. Forewing whitish, ba£e brownish. A black spot at the base below the cell, a 
smaller one above it. A brownish-grey spot at the cell-end. Inner margin and marginal area brownish- 
grey, except at the costal margin. Submarginal line whitish, irregular. According to the author, similar to 
phaga, but an exterior row of spots is not mentioned at all. J 36 mm. Formosa. 
I. acutistriata Mell (93 g). Forewing light brown with dark olive brown striae and spots. One very 
large one below the base of the cell and behind the cell. The spots of the submarginal row are also large; 
in one of 3 specimens prolonged far inwards. Hindwing also intensely spotted dark. Fringe as light as the 
ground-colour. $ 26—36 mm. Malang (Java). 
1. magma Joannis is almost a faded acutistriata (93 g). Ground-colour of forewing whitish with greyish- 
yellow striae. The brownish-black postcellular spot is large, the submarginal band distinctly contrasts with 
the finer transverse streaks. Black scales near the base, around the exterior band and at the distal margin. 
Fringe spotted white and greyish-yellow. The ground-colour and the numerous spots of the hindwing corre¬ 
sponding to the forewing. 25—40 mm. Hanoi. 
I. watsorti Hmps. Grey. Forewing with fine dark striae, suffused with darker grey, excepting only a 
triangular whiter central spot. A black basal streak below the cell, and a faded blackish oblique exterior 
band. A black discal spot before it, with a white dot outside. Traces of a submarginal line. Hindwing with 
numerous fine dark striae. $ paler. 24—32 mm. Madras. 
1. obliquifasciata Mell (93 g). Ground-colour of forewing whitish with fine greyish-yellow striae which 
are almost invariably absent in the cell. A long blackish wedge below r the cell. A blackish-brown roundish 
spot behind the cell, and behind this spot begins a somewhat darkened exterior band running to the centre 
of the inner margin along which it extends in the shape of dark scales almost to the base. The spots of 
this band are finely edged with black. Fringe spotted dark. Hindwing purely white, a small dark spot 
near the anal angle at the fringe. 28—36 mm. Canton. — grisescens Mell may be a distinct species, as the 
author presumes. Forewitrg more faded, somewhat darker than obliquifasciata. The distal row of spots 
smaller and darker. But above all the hindwing is darkened especially at the veins, though without recog¬ 
nizable spots. J 24 mm. Sumatra. 
I. baibarana Mats, is somewhat similar to a large grisescens. Forewing greyish-white with a brown 
marking. A spot below the base of the cell and at the cross-vein. Of the spots of the exterior band the
