wing opalescent white, the outer area brown from lower subcostal to above anal angle^ where 
it is suffused towards base above internal uervure, with an inward-pointed tooth at submedian 
iiervure, and bounded inwardly by fine double black lines. Underside opalescent except the 
outer area ; the markings of fore wing at end of cell showing through. Head, thorax, and 
abdomen pure white, with a broad dorsal brown band ending as a point at forehead and anal 
segment; lateral brown bands from collar to base of fore wings. Legs slightly ochreous. 
Dodanga cristata. (Plate CLVI. fig. 7.) 
Expanse 1 inch. 
Male. Wings smoky black. Fore wing with the black spot in the middle of the cell 
and lunule at end of it as in D. truncatalis and D. lobipennis ; a large discal patch of raised 
scales beyond the cell, which is also present in D. truncatalis, but not in D. lobipennis. 
Hind wing with a faint postmedial dark line and pale antecilial one as in both the other 
species ; the tuft of long hairs springing from the base of the inner margin are pale ochreous, 
in D. truncatalis they are reddish ochreous, in D. lobipennis black. Underside of fore wing 
with a slightly curved postmedial line from the costa not quite reaching inner margin. 
The males of the three species of this genus differ only in their secondary sexual 
characters ; the females are unknown. D. truncatalis alone has large tufts of scales springing 
f I'om each side of the base of the tibia of hind legs. 
Notarcha dubia. (Plate CLV. fig. 16.) 
Notarcha dubia, Warren, MS. 
Expanse, S ^\ inch, ? 1^ inch. 
Male and female. In size and markings just like N. ruralis, Scop., of which it appears 
to be the Indian representative ; but the ground-colour, instead of being pale straw-colour, 
is always more or less suffused with fuscous \u N. paleacalis, Guen.), the markings in 
consequence being rendei'ed less conspicuous. 
Also in coll. B.M. from Dharmsala. 
Orthospila angulifascia. (Plate CLV. fig. 10.) 
Expanse 1 inch. 
Female. Silvery white. Fore wing with basal, two subbasal, and antemedial, straight, erect, 
somewhat dusky orange-yellow bands ; a less distinct band at end of cell, diffused outwardly 
along second median nervule ; a postmedial band outwardly-oblique from costa to first 
median nervule, then bent inwards along it to below end of cell, then inwardly-oblique to 
centre of inner margin ; a submarginal and bright yellow marginal bands. Hind wing with
