does not extend beyond the cell, the green tint is more prominent; distal margin behind the marginal line 
somewhat darker. Under surface yellowish ochreous; the distal line and subterminal line are marked in the 
costal half of the forewing. In the hindwing the line is marked by a coarse diffuse black shadow widening from 
the costal margin to vein 2, where it terminates. This is the usual colouring of this species which I denote 
as ab. normalis ab. nov., whereas the form bracteata from Ceylon is dark brown. These brown forms occur normalis. 
sporadically in all the species of the group. It seems hitherto to be confined to Ceylon; the lighter normalis 
occurs in the Khasia Hills in Assam, in Sikkim, the Malay Peninsula, Java and Dili. Expanse of wings in the 
d 44 mm, in the $ 52 mm. — In celebensis subsp. nov. the distal line is broad brown, not double, slightly distally celebensis. 
convex instead of straight and with a dull brownish cloud around the angle. Hindwing beneath without a 
black band, the marking of the forewing as well as the brown line on the hindwing very feeble. A couple from 
Tondano (North Celebes); type in the Tring Museum. Size the same as that of bracteata. 
C. praeusta sp. nov. (49 k). Forewing greyish ochreous, powdered with brownish, particularly at praeusta. 
the distal margin; proximal line fine, blackish-brown, obliquely distally to the median on which it is acute- 
angular, and obliquely inwards; distal line double, blackish-brown, the proximal portion very fine, angular 
on vein 6, the apical area behind filled with blackish-brown; the black subterminal spots represent the dents 
of an acutely dentate line, and a dull lustrous line at the base of the fringes. Reniform spot oval, oblong, hardly 
noticeable. Hindwing traversed by all the lines, the costal-marginal area light ochreous. Under surface yellow; 
cellular spot of forewing, the distal and subterminal lines the oblique shadow, and the thick band of the hindwing 
are all black. 1 $ from Pulo Laut (Borneo), June 1891, captured by Doherty. Type in the Tring Museum; 
expanse: 44 mm. 
C. patrana Mr. (— biocularis Mr. S) (49 k). Forewing dark greyish-brown, the markings blurred, patrana. 
Much flown and damaged specimens are paler, but fresh light specimens seem not to occur, biocularis Mr. 
is apparently only a dark $ of it. This species lives in Sikkim and Assam (North India). 
C. obliquistriga sp. nov. (49 k). Forewing yellowish brown, crossed by 5 dark brown stripes obliquely obliquistri- 
extending distally. Moreover, the species corresponds with brown specimens of the preceding patrana. All - ia - 
the specimens are from Assam, so that it might be a local form of patrana, but I have not seen any specimens 
from Sikkim, where patrana also occurs. 
C. gelidata Wkr. (— argentilinea Wkr., argentilinea Snell.) (49 i). Forewing bone-white, a very dull gelidata. 
brownish proximal, median and subterminal line; a silvery pearl-coloured, somewhat raised stripe along the 
subcostal vein and on the submedian fold to the hind-margin before the anal angle; marginal line before the 
apex broad silvery; from the base along the centre of the cell almost to the subterminal line a silvery streak; 
a short similar one at the base of the submedian fold; a raised oval lead-coloured spot with a black edge 
on the upper half of the discocellular, followed by 2 brown obliquely situate spots at the lower half. Hindwing 
with a feeble brownish subterminal line above the anal angle, marked with small silvery scales which also occur 
at the distal margin. Type of gelidata from Borneo; that of argentilinea Wkr. from Singapore, of argentilinea 
Snell, from Java. In the Tring Museum there are specimens of Moulmein in Burma as well as from Calcutta. 
C. splendens Warr. (49 k). Forewing creamy white, tinted with olive; costal margin deep red-brown, splendens. 
fine, the proximal margin decorated with small silvery scales; cellular spot large, ear-shaped, deep chestnut- 
brown, bordered with small silvery scales; a brown spot at the lower cell-angle; a spot of silvery scales at the 
base of the cell, from which a line extends through the centre of the cell and the cellular spot, widening behind 
it and terminating in a kind of dingy spot; a silvery subterminal line parts from the subcostal behind its centre, 
being incurved behind vein 5, then parallel with the distal margin. Marginal line silvery, broad, crossed by 
the light veins; fringes yellowish-red. Hindwing with a short silvery line from the hind-margin at %; marginal 
line below the centre silvery; fringes yellowish-red. Under surface unicoloured pale creamy. Face and palpi 
deep brown; thorax and abdomen creamy. The silvery scales in this species show a fiery steel-like exterior, 
unlike the more lustreless silver of gelidata ; besides it is smaller and is at once recognisable by its dark costal 
margin. Type from Tawaya in the north of Palos Bay (Celebes); also from Sula Mangoli in the Tring Museum. 
A form from Africa is very closely allied to it and might be identical with it. 
C. nana sp. nov. (50 a). Forewing light fawn-coloured, traversed by diffuse, glaring, fawn-coloured nana. 
bands being partly laterally contiguous. Costal margin tan-coloured, underlined by a bronze streak which 
is set with small metallic scales in the centre; a spot of similar scales on the subcostal before the centre; behind 
the centre on the subcostal a dark bronze line set with small metallic scales, bending round before the apex 
and turning to the subterminal line, indented above vein 5. A similar metallic line at the distal margin, crossed 
by light veins; fringes tan-coloured; costal margin before the apex reddish. A line of small metallic scales 
extends from the base through the cell to a darker spot behind it. The cellular spot is a lead oval, with a brown 
spot at the lower cell-angle. Hindwing lighter, particularly in the costal half; the hind-margin with traces 
of a subterminal and terminal line; under surface dull whitish. In the shape this species resembles Alb. humerata
