A. nigriradiata Hmps. (13 i) is pink on its body and wings with 3 black transverse lines, black dots nigriradm¬ 
in the basal area and on the transverse vein, and black antemarginal vein-streaks. Bhutan. ta 
A. ridibunda Snell, is easily distinguished from the preceding, similar, somewhat larger species by ridibunda. 
the complete transverse row of black vein-streaks before the anterior transverse line occurring also in the basal 
area; the vein-streaks in the marginal area are much shorter, more punctiform; the ground-colour is paler, 
very slightly tinted orange. From Batavia. — The larva was found on young leaves of Durio zibethinus L., 
it has a light body which, however, appears dark owing to its dark grey or black hairing; on the 4th and 5th 
rings there are 2 brown hair-brushes, laterally on the 5th some more hair-appendages; head black. The pupation 
takes place on a leaf in a cocoon surrounded by a crest of hair. The imago is yielded after eight days. 
A. metaphaea Hmps. (17 b) has ochreous-yellow forewings mixed with blackish; in the basal area metaphaea. 
some black streaks; a rudimentary median line is on the median united with the anterior transverse line; a 
black cell-spot; the posterior transverse line forms a very sharp distal tooth on the middle radial vein, behind 
it there are long black vein-streaks. Hindwing blackish-brown with ochreous-yellow fringes. Sikkim. 
A. miltochristoides Rothsch. $ resembles a large Miltochrista niveata. Antennae light brown, head miltochns- 
light yellow, thorax light pinkish carmine; abdomen light yellowish wood-coloured; forewings light pinkish- toide» 
carmine, a basal spot on the subcostal vein, an antemedian zig-zag line, an oblique, broad median line, one 
macula, and a postmedian line being twice sharply angled, running from the black line, from the black veins 
edged by yellow to the margin. Hindwings pink. Length of forewings: 13H mm. Khasia Hills, taken in June. 
45. Genus: Macliaeropliora Hmps. 
The only small species known has a stunted proboscis, short, porrect palpi, in the doubly combed 
antennae; the posterior tibiae are without the middle spurs; the abdomen is coarsely haired. On the rather 
long forewings the 1st and 2nd subcostal veins are on a joint footstalk, but the uppermost subcostal vein after 
a short distance passes over into the costal vein and anastomoses with it. On the hindwing the 1st median 
vein and 3rd radial, as well as the 2nd subcostal vein and 1st radial are petioled. 
M. fulvipuncta Hmps. (17 b) is blackish-brown; the abdomen beneath orange-yellow; the forewing hdvipuncta. 
shows in the middle of the proximal margin an orange-yellow spot varying in size, often also traces of spots 
at the base and in the marginal area. The 0 is said to be without wings. Ceylon. 
46. Genus: Ovipennis Hmps. 
Distinguished by a very convex costal margin and round apex of the forewing, also the distal margin 
being very round. Proboscis well developed; the porrect palpi project somewhat beyond the forehead. On the 
forewing the two lower radial veins rise separately, the 1st and 2nd subcostal veins proceed almost from the 
same place, the 1st being strongly curved. On the hindwing the 1st median rises from below the lower cell- 
angle, the middle radial vein from above it; the 2nd subcostal vein and 1st radial are petioled. 
0. dudgeoni Elw. (27) has yellowish-white forewings with 2 large, longitudinal blackish-brown dudgeoni. 
spots extending almost to the margin, above and below the median; fringes towards the apex back. Hindwing 
pale yellow, in the disc with a large, blackish-brown spot. Sikkim. 
0. binghami Hmps. Forewing in the basal area orange, distally light reddish-brown, towards the binghami. 
margin darkened; margins white. Hindwings blackish-brown, at the proximal margin light reddish-brown, 
fringes white. Thorax white. Abdomen ochreous-yellow, towards the end grey; venter white. Burma. 
47. Genus: Idoptemun Hmps. 
The shape of the wings is round as in Ovipennis, but the ascending palpi project beyond the forehead. 
The 3 last abdominal rings are strongly widened, so that the abdomen appears to be strangulated. The venation 
is likewise similar, but on the forewing Ri proceeds from the upper cell-angle; on the hindwing M, and R 3 from 
one and the same place of the lower cell-angle.
