LITHOSIA. By Dr. M. Draudt. 
perdentata. L. perdentata Druce (14 k) is easily recognized by the median line being flawed in an acute angle 
below the cell; in the basal and marginal areas there are black stripes on the ochreous-brown forewings. Perak. 
divisa. L. divisa Wkr. (15 a) is very much like the preceding and discernible by the median line being only 
feebly bent, and a black discal dot. Borneo, Java. 
setiniformis. L. setiniformis Hmps. (15 a) placed by Snellen to divisa, has an entirely straight median line. 
Java. 
reticulata. L. reticulata Moore (Vol. II, t. 13 c) has brownish forewings watered darker, with a postmedian line 
broken in an acute angle. North West Himalaya, Sikkim. 
rubrescens. L. rubrescens Hmps. Head and thorax are light red-brown, tinted yellowish; abdomen grey, tinted 
brownish-red. Forewing light yellowish red-brown with an indistinct, blackish, broken postmedian line. Hind¬ 
wing whitish, faintly tinted red-brown. Expanse of wings: 40 mm. Formosa (Kayi). 
tricolor. L. tricolor IF il. Forewing light cinnamon-coloured on the basal two thirds, in the distal third blackish. 
Hindwing creamy white, at the margin a blackish band; the latter towards the costa broadest, below the middle 
slightly notched and at the anal angle oblique. Beneath like above, but the basal two thirds of the forewing 
creamy white and the costal margin of all the wings streaked yellowish, 28 mm. From Kantaitsan (Formosa), 
one $ taken in May. 
pentaspila. L. pentaspila Hmps. Head, thorax, and abdomen ochreous-yellow; anterior tibiae and tarsi blackish. 
Forewings ochreous-yellow, with a postmedian oblique row of 5 black, small spots: below the costal margin, 
in the cell-end, below the 3rd radial vein a somewhat distally flawed spot, a more strigiform one on the sub¬ 
median fold, and at the proximal margin. Hindwings light ochreous-yellow. Expanse of wings: 26 to 30 mm. 
Singapore; Borneo. 
atrifrons. L. atrifrons Hmps. Head, collar, shoulder-covers, chest and legs reddish-yellow; palpi, forehead and 
forelegs blackish. Mesothorax and base of abdomen greyish-white, the rest of the abdomen yellow. Forewings 
yellow, dusted whitish, hindwings yellowish-white. Expanse of wings: 26 mm. Nicobars. 
pallida. L. pallida Moore (Vol. II, t. 13 c), likewise reaching into the palearctic region, from the North West 
Himalaya, shows on its brownish-grey forewing antemedian and postmedian black costal spots, besides at 
the lower cell-angle and in the middle of the submedian fold. The $ is without the anterior costal spot. 
quadrisig- L. quadrisignata Moore (15a). The forewing is light brown, thickly dusted purple-blackish; the 
nata. } jasa } two thirds of the costal margin remain light with 2 dark spots before and behind the middle. Hindwings 
light brownish. Sikkim. 
transfascia- L. traiisfasciata Rothsch. Antennae light brown; head and thorax orange-reddish, abdomen dirty buff. 
ta - The forewing is yellowish-white, in the distal quarter maize-coloured, and at the base a narrow black transverse 
band, before the middle one, behind the middle two similar ones; the most distal one is broken up on the upper 
radial, where the scent-organ of the under surface ends. Hindwings reddish-yellow. The 2 is larger and exhibits 
another antemedian transverse band. Length of forewings: ^13 mm, ^ 18 mm. Oetakwa River, Snow Moun¬ 
tains in Dutch New Guinea. 
unifascia. L. unifascia Rothsch. Antennae black, head orange; thorax dark brownish-grey, collar and base of 
shoulder-covers orange; abdomen reddish-grey. Forewing greyish-brown with a dark grey, postmedian trans¬ 
verse line; base and costal margin orange. Hindwings reddish buff. Length of forewings: 16% mm. Kumusi 
River in North East British New .Guinea. (July). 
basigera. L. basigera Wkr. (== ruma Swinh.) (15 a) is a large species with dark brown forewings and a purely 
white basal half of the costal margin and a black spot in it near the base, from which an oblique, dark band 
runs to the middle of the proximal margin, broken pointedly on the submedian fold; postmedian traces of a 
dark transverse band, hindwings orange-yellow. Beneath the costal margin is orange-red; in the $ yellow. 
Nilgiris. 
apicalis. L. apicalis Wkr. (15 b). In the ^ the forewing is yellowish grey with a broad, brownish-black marginal 
band being absent in the $, in which it is replaced by black spots at the costal margin behind the middle, in 
the cell-end and on the submedian fold before the middle. Borneo, Pulo Laut, Java. The larva is brown 
with black lines across the dorsum and on the sides, with long grey and black hair; the head is orange-yellow; 
it lives on moss and lichens, also on the leaves of Tamarindus and Eugenia, and changes into a cocoon yielding 
the imago after a fortnight.
