Palj>i short, porrect, antenna with one row of long (in the $ shorter) pectinations. Fore wing with a 
produced apex. Distal margin below it excised. Neuration: in the forewing veins 6 + 7 and 9 + 10 stalked,

numicu- D. numicusaria Wkr. (= capetusaria Wkr., circulitaria Wkr.) (58 e). <$ pale ochreous brown, $ browner 
saria. +th a very oblique rusty yellow line from the apex of the forewing to the inner margin of the hind wing near 
sinelinea. the base. Some white submarginal spots at the apex of the forewing. 36 — 40 mm. Nort India. — In sinelinea 
Warr. the line is absent; at the apex black submarginal spots. 
subobscu- D. subobscurata Wkr. (58 e). Pale olive brown, $ more reddish. Apex of forewing brown. A dark spot 
mUi. the cell-end of both wings. A brown line from the apex of the forewing to the inner margin of the hindwing 
near the base. Submarginal spots in the dark, in the $ lighter. 45 mm. Nilgiris, Ceylon. 
hypopyrata. D. hypopyrata Sn. Forewing and hindwing of $ olive greenish, at the base darker; with a greyish-white 
line from the apex of the forewing to the centre of the inner margin of the hindwing, bordered by dark olive. 
Distal area of forewing somewhat lighter, at the apex whitish. On the cross-vein a light grey spot, before it 
in the cell dark brown. Hind wing behind the cell striated dark. $ dark violettish greyish-brown. Transverse 
lines greyish-white, only at the apex of the wing distinct. Interior angle dusted with violettish-grey. 38 to 
49 mm. Sumatra. 
violacearia. D. violacearia Leech. Violettish-grey, at the costal and distal margins brown, with a dark brown 
oblique line from the apex of the forewing to the middle of the inner margin of the hindwing, being inside edged 
with pale violet. On both wings a black discal spot. 33 mm. West China. 
argentili- D. argentslinearia Leech (Vol. II, pi. 48 a). Olive brown with a silvery grey oblique line on the forewing, 
neana. an g U i ar below the costal margin, incurved above the inner margin. Within this 2 or 3 fine undulate lines. 
Distal area golden brown. Hindwing with 2 silvery grey median lines and 3 undulate lines in the -distal area. 
30 mm. Japan, from Jesso to Formosa. — In Vol. II (p. 196) placed as Mimozethes to the Drepanidae. 
lilacinaria. D. lilacinaria Leech. Dark brown, forewing dusted with lilac, in the distal area golden brown, with 2 
fine lilac transverse lines. The exterior one below the costal margin of the forewing angular to the centre of 
the inner margin of the hindwing, distally bordered with golden brown. On both wings a black discal spot 
and an indistinct dark submarginal band. 36 mm. West China, probably chiefly palaearctic. 
dichromata. D. dichromata Wkr. (= insignis Btlr.). Similar to numicusaria (58 e). Forewing yellowish-browm, 
hindwing redclish-browm, at the base light greyish-yellow. With a rusty brown line from the apex of the 
fuscibrun- forewing to y 3 of the inner margin of the hindwing. On the fore wing an indistinct discal spot. —- fuscibrunnea (2) 
nm. Warr. is violettish brown, striated dark. The margins of the wings are dark smoke-browm. Cellular spot and 
transverse line hardly visible, but the white submarginal spots of the $ are present. 45 mm. Mysol, Russel Is., 
Salomons Is. — Some other forms have been denominated ochracea, grisea, and nigromaculata by Warren, 
their names explaining the various colours. 
uniformis. D. uiliformis Warr. Forewing yellowish-grey, densely dusted with lead-grey, with a dark spot on the 
cross-vein. Sometimes a rust-coloured oblique line is visible, similar as in dichromata. Hindwing of the same 
colouring. 45—48 mm. Salomons Is. 
mo'estaria. D. moestaria Wkr. Blackish, with a rusty red line from the apex of the forewing to the centre of the 
inner margin on the hindwing. Perhaps a dark form of dichromata. 45 mm. Sumatra. 
unilineata. D. unilineata Wkr. Mouse-coloured with a rusty red line from the apex of the forewing to a little behind 
the centre of the inner margin on the hindwing. Forewing with an indistinct bent browm interior line and a 
black discal spot. 45—50 mm. Sumatra, Celebes. 
pallidaria. D. pallidaria Pag. (= bilineata Hmps.) (58 e). Wings reddish-brown with dark undulate hues and 
black central dots edged with white. Interior line angular at the upper and lower cell-margins. A double 
exterior line filled with dark, behind it black submarginal dots. The latter also on the unmarked hindwing and 
before them white dots. 50—55 mm. Palawan, Halmaheira, Burma. 
iorridaria. D. torridaria Mr. Fore wing greyish-brown with a dark discal spot. Interior line rust-coloured oblique

lines. 46 mm. North India, Tonkin.
