indistinct. Submarginal line white, with black notches inside. Hindwing brownish. 30 mm . Borneo. Since 
the J was described in 1863, it is only a few years ago that the species was also found in Tonkin. 
Ch. meialophota Hmps. (36 c) shows the anal angle on the hindwing somewhat plicate and provided 
with a hair-tuft. Forewing white, slightly shaded with brownish. Interior line black, straightly inward as far 
as the submedian fold. Median line undulate, outward, a black streak behind it in the submedian fold. Reni- 
form macula indiscernible. Exterior line fine, black, oblique as far as vein 6, then undulate to the inner margin, 
a brownish parallel line behind it. Submarginal line white, with black dots. Hindwing white, diaphanous. 
30—35 mm. India, Ceylon, Malacca, Sumatra. 
Ch. distincta B.-Bak. (36 c). Forewing white, rusty red before the interior line and behind the exterior 
line, black at the middle of the inner margin, grey at the distal margin. Interior line black, undulate, obliquely 
outward. A black spot at the costal margin behind the exterior line, notched, parallel to the margin. The black 
submarginal line is white outside. Hindwing whitish, brownish at the margin. costiplagata B.-BaJc. is greyish 
blue and olive green on the typically rusty red places; it may be that these are the natural colours and the 
type has changed by dampness. 22 mm. A few $$ from New Guinea. 
Ch. glaucopasta Hmps. (35 k). Forewing pale olive grey. Interior line black, white inside, notched, 
widely incurved in the submedian fold. A black streak at the cross-vein. Exterior line black, white outside, 
outward as far as vein 4, introangular in the submedian fold, blackish before it. A black spot at the costal margin 
behind the line. Submarginal line white. — In perakensis Strd. the forewing is whiter and less green. Hindwing 
brownish white. — 20—22 mm. Sikkim, Assam. 
Ch. multilinea B.-Bak. (36 c). Forewing silvery white with a black marking. Interior line notched as 
far as the lower edge of the cell, then far inward in the submedian fold, with single rays to the exterior line 
which is oblique as far as vein 6, then dentately inward. Submarginal line slightly undulated. Hindwing whitish, 
browner at the margin. $ 22 mm. New Guinea. 
Ch. phaeoleuca Hmps. (36 c). Greyish white and brownish, with black lines. Interior line white inside, 
notched, straight, somewhat outward, thus quite different from multilinea. Median area pale brown. Ex¬ 
terior line white outside, somewhat dentate, excurved behind the cell, then rectilinear to the inner margin; 
dark behind it at the costal margin. Submarginal line of black spots, somewhat undulate. Hindwing as in 
multilinea. 25 mm. 1 S' known from Ceylon. 
Ch. ruficirra Hmps. (Vol. 3, pi. 53 d) occurs in Japan and was therefore dealt with in Vol. 3, p. 290. 
Some specimens are also known from Sikkim and Assam. — Symitha, fasciosa Mr., which has remained unknown 
to Hampson, seems to be the same species. 
Ch. polia Hmps. (36 d). Forewing greyish white, brownish at the base. Interior line doidde, slightly 
excurved to the inner margin. Median line black, somewhat oblique, rather straight. A black dot at the cross¬ 
vein. Exterior line sharply extra-angular at vein 6, and introangular below it, undulate as far as vein 3, then 
inward to the inner margin; blackish behind it at the costal margin. Submarginal line blackish, notched, distinct 
only in front. Hindwing as usual. 24 mm. 1 S' known from Assam. 
Ch. cana Hmps. (36 d) differs in its size and the almost absent marking. Forewing greyish white and 
pale brown. Interior and median lines indiscernible. Exterior line likewise indiscernible, oblique as far as 
vein 7, then it is represented by a series of fine dots. Submarginal row indicated by black streaks. Hindwing 
brownish white, somewhat diaphanous. $ 32 mm. Burma. 
Ch. perfecta Swh. Forewing grey, dusted dark. A deep black spot at the middle of the costal margin, 
with its apex downward, narrowly prolonged on both sides at the costal margin as far as the base and apex, 
a white spot at the lower angle, enclosing 3 black dots, one more below them near the inner margin. The centre 
of the wing with 2 black spots on a whitish ground. Exterior line white, dentate, excurved, submarginal line 
also white. Hindwing dark brownish grey. 18 mm. Assam. 
Ch. araca Swh. Forewing greyish white, dusted dark, with 4 strongly notched black transverse lines. 
The first two near the base, nearing each other at the inner margin. The third line excurved in the middle, a 
black spot behind it at the costal margin, a similar spot at the submarginal line, all the lines slightly edged with 
white. Hindwing whitish, diaphanous. 25 mm. Assam. 
6. Genus: DilopBfiothrlgfcii Hmps. 
Most, of the species resemble Char, metalophota (36 c) in the shape of the wings, but the forewing lacks 
the areole, and veins 10 + 8 + 9 are stalked. The hindwing of the typical species exhibits a hair-pencil at the 
inner margin and one below vein 8. Type: chrysorrhoea Hmps. All the species are continental or Indo-Chinese, 
only one is from Borneo.
