C. innocua Btlr. (= costimacula Stgr) (Vol. 2. pi. lOg), largely Palaearctic and therefore described 
in Vol. 2, p. 48, is mentioned here only because it has also been found in Formosa whose Fauna belongs to 
the Indo-Australian Region. 
C. cretacea Hmps. (13 i). ? white, shaded with reddish-brown, costal margin rufous at base; a few 
costal spots and tufts of scales likewise rufous. Antemedian line thin, angled outwards to the patch of raised 
scales in the middle of the cell. Postmedian line punctate, curved outwards below the costa, sharply angled 
on 4, then making a sharp turn. Hindwing white, faintly shaded with brownish at margin. Bombay. A 
minute species, 14 mm. 
C. pumila Snell. (= spreta Btlr., tetrophthalma Meyr., minuta IBnps., hampsoni Ky .) (13 g) is the 
smallest form of the entire genus and indeed of the whole Arct.iid family. Pale grey, most delicately marked 
with a longitudinal streak in the middle of costa and some oblique rows of spots before and beyond the 
middle. Hindwings whitish, with faintly brownish termen. Widely distributed over the entire Indian Region, 
from India proper to China, and eastward to New Guinea; enters the limits of the Palaearctic Region at 
Shanghai, of the Ethiopean on the island of Sokotra. One of the more common species. 
C. aroa B.-Bak. ( 1 3 g) resembles in ? a large pumila; but the cf has on the forewing the dark median 
band very distinct, although irregular and but slightly differing in shade from the dark ground; a black-brown 
scalloped terminal line, very distinct in cf. Forewing grey-fuscous, terminal half suffused with dark fuscous 
in cf. New Guinea. 
C. squalida Stgr. ( = musculalis Saalm., fraterna Moore, vanhasselti Heyl., ceylonica Hmps., desmotes 
Trnr .) (Vol. 2, pi. lOg). This widely distributed, minute species has been described in Vol. 2, p. 48. It is 
one of the commonest Indo-Australian species, occurring from Cashmere and Southern China to Australia 
and the South Sea Islands, and being also found in Madagascar. 
12. Genus: Acatapaustus B.-Bak. 
Palpi hairy, upturned, terminal segment small, erect. Antennae 3 / 4 pectinate, mid tibiae with 1, hind 
tibiae with 2 pairs of spines. On the forewing vein 2 arises at 3 / 4 °f the length of cell, 3 precisely at angle, 
4 and 5 directly above, 6 and 7 immediately below the upper angle of the cell; 8, 9 and 10 stalked, with 
long stem from upper angle. On the hindwing 2 is given forth a short distance before the angle of cell, 3 
and 4 are stalked, arising at angle, 5 below the discocellular, 6 and 7 stalked, 8 united with 7 basally. 
Type A. basifusca B.-Bak. from New Guinea. Two species are described, both unknown to me; the types in 
in the collection of the author. 
A. basifusca B.-Bak. Head, antennae and thorax brownish, abdomen grey-brown. Forewing pale 
brown with dark median streak, behind which the pale ground-colour most distinct, towards anal angle slightly 
diffuse. Hindwings whitish, termen darker. ? darker than cf; Dinawa (New Guinea). 
A. ekeikei B.-Bak. Head and thorax pale, abdomen brown-grey. Much larger than the preceding 
species. The dark median band cut off very straight distally, the whole terminal third of forewing obscured, 
hindwing only at apex. Taken in March at Ekeikei (New Guinea). 
II. Subfamily: Lithosiinae, Lichen-moths. 
The Lithosias of which we illustrate here over 400 Indian species, are a far more homogeneous group 
than should be supposed from the great number of genera that have been established (about 250). As above 
mentioned, no less than 170 genera are monotypic or contain at the best 2 often very closely allied forms. 
In the diagnosis of these monotypic genera we will content ourselves to give only the most indispensable 
characteristics, since nothing can be gained from a diagnosis which cannot point out any features common 
to several more or less closely allied genera. Of larger genera with say a dozen or more of Indo- 
Australian species we can only name 12, namely the gaudily spotted Castulo, the daintily marked Thalarche, 
the plain Philenora, the often delicately pink Miltochista, the Chionaema with their plain colouring, beautifully
