S. confusa Walk. Forewing pale rufous with some brown irroration, in some instances with two slight 
brown striae on discocellular and one beyond; fringe white with a rufous flush; hindwing ochreous white, the 
costa beneath rufous. Ceylon. 
S. conspersa Moore (5i). Forewing ochreous white, densely irrorated with reddish brown, generally 
with two slight brown striae on discocellular and one beyond; hindwing white, the costa beneath ochreous. 
Punjab, Sikkim, Bengal, N. India; Raipur, Central Provinces. 
2. Subfamily Mominae. 
Insects, as a rule, of larger size and stronger build than the Acronictinae ; characterised in particular 
by the hairy eyes and vein 5 of hindwing being well-developed. The larva, as far as known, more or less beset 
with hairs. The species are nearly all denizens of the Tropics. 
1. Genus: ^loiiisa Hbn. 
Tongue present; irons smooth; palpi obliquely upturned, the second segment long, clothed with thick 
hair beneath, the third short, rounded; eyes hairy; antennae of $ filiform, simple, basal segment with a tuft of 
hair; vertex tufted; shoulders and patagia distinct, semi-erect; dorsum tufted; pectus and venter woolly; with 
the cell of forewing beneath clothed with short rough hair-scales; the hindwing with similar scales in a patch 
at base of costa and along basal half of median vein; head, thorax, and forewings white with black markings; 
dorsum and abdominal margin of hindwing yellow. Larva hairy, forming a rough oval woolly cocoon in a rolled 
up leaf. Type M. ludijica L. 
M. champa Moore (5 h) ($Vol. 3, pi. 3 a). Forewing chalk white; the markings resembling those of 
ludijica, but better developed; a black spot at base of costa; a small black streak at base of subcostal and vein 1, 
and a larger wedge-shaped one at base of submedian fold; inner and outer lines double; the inner arm of inner 
line thick, the outer arm thin, angled outwards on subcostal vein, on submedian fold, and below vein 1, inwards 
in cell 4 and on vein 1, interrupted in places, the outer arm becoming macular below middle; orbicular stigma a 
black ring, usually oval: median line very thick, single, marked by a black costal inwardly oblique spot, an oblique 
black bar across cell nearer termen, continued as an oblique black streak to inner margin, interrupted in 
lower half of submedian interval, with black horizontal streaks on veins 1, 2, and the fold between them; 
inner arm of outer line fine, dentate, projecting between veins 3 and 5, preceded by a short dentate line; outer 
arm regularly curved, lunulate dentate, the teeth well marked and black, that on submedian fold larger, the line 
starting from a black costal spot; subterminal line formed of inwardly pointed black teeth; some elongated 
black terminal marks on the veins; fringe mottled, white and black; hindwing white; the veins in terminal 
half black; a dull blackish diffuse cloud at apex in q , extended in $ as a well defined border to anal angle; an 
interrupted black terminal line and a small black spot at anal angle; fringe mottled, white and black; inner 
margin broadly, with the fringe, yellow; underside of forewing blackish, with the inner margin white, and the 
scales in cell of $ dull yellow, in $ black and hairlike; costa of hindwing with two black spots and air apical 
blotch. Described originally from Dharmsala in the Punjab; occurring also in Sikkim and Assam, Ivhasia Hills. 
A form occurring in the same localities, but always smaller, may be separated as ab. diffusa ab. nov. (5i); in 
it the ground colour is slightly tinged with olive grey; the median line below middle forms a continuous black 
lunulate dentate line preceded by darker grey clouding; the orbicular stigma is small and round; in the hindwing 
the dark scaling of the $ is diffuse, not forming a defined border, and in the $ is restricted to the costal area 
above subcostal vein and vein 6; of both these forms there occurs, in the Punjab only, an ab. obsolescens ab. nov. 
(5 i), in which the ground colour is pearl grey instead of chalk white; the markings, except along costa, all finer 
and duller black, to a great extent blurred and obsolescent, especially in terminal half of wing; the thick 
median line alone remaining black; the outer arm of outer line is finely and acutely dentate; hindwing pearly 
white, with the veins dark ; the costal area in the $ dull grey, the apical area in the ^ smoky fuscous. In the 
British Museum collection there are examples from Kangra, Thundiani, Murree, and Sultanpore, all of the 
smaller form; in the Tring Museum a $ from Kulu of the larger form. 
M.ni grescens Warr. (8 i). Forewing greenish white; the dark markings all thickened, the inner and median 
lines and partially the outer line connected by horizontal olive bars along vein 1, the submedian fold, and the 
median vein and vein 2; the projecting part of inner arm of outer line beyond cell filled in with olive; a blackish 
terminal shade from 4 to 7; hindwing suffused in both sexes with blackish, the basal two-thirds in the less 
thickly; inner margin dull yellow; dorsum yellow, with the anal segment black except at extremity, but without 
the row of dorsal spots. Ceylon. Described from 1 and 2 $$ in the Biitish Museum Collection. 
2. Genus: Ts*isBil«&i<Ies Btlr. 
Tongue well-developed; irons smooth, rounded; palpi porrect or upturned, short, the second segment 
rough-haired below, the third short, blunt; antennae of typically, well pectinated; eyes hairy; thorax and ab¬ 
domen clothed with hair; shoulders and patagia distinct; dorsum tufted; pectus and tibia hairy. Larva hairy.
