C. sericea Hmps. (21c, cl). Forewing and hindwing uniform silvery white; anal tuft with some 
yellow at sides; face and palpi as in C. tibialis. The species is recorded from Ceylon, Burma, Cocos 
Keeling Id., Formosa, Christmas Id., and New Caledonia. 
83. Genus: I'iiassasisna Walk. 
Tongue well developed; frons smooth; palpi upturned, smoothly scaled, and appressed to frons; 
antennae of $ simple, filiform; thorax and abdomen smoothly scaled; a small crest on basal segment 
of dorsum; forewing with apex blunt, the termen evenly curved; neuration normal. Type C. tibialis F. 
Sect. I. Forewings large without lines or markings. 
C. tibialis F. (= cygnus Walk., glabra Walk., celebensis Snell., mariae Mob.) (21 d). Forewing and 
hindwing silvery white, without black terminal dots; thorax and abdomen white; palpi orange above and 
at tips; frons orange below, fulvous above; antennae yellow, except at tips; fore femora orange above, 
with a fuscous streak; fore tibiae orange with two black spots; tarsi orange, with one black point on 
first, sometimes also on second segment. A common and widely spread tropical insect, found in India, 
Ceylon, Sumatra, Celebes, New Guinea, Australia, Rarotonga, Tahiti. The types both of tibialis F. and 
glabra Walk, from Australia, that of cygnus Walk, from India. 
C. tibiopunctata Beth.-Baker (21 d). Forewing uniform silvery white, with a black point on ter¬ 
men below apex; hindwing white; thorax and abdomen white; palpi orange above, black at tips; frons 
orange below, black brown above; antennae, except basal segment, blackish brown; fore femora orange above 
with fuscous streak; fore tibiae orange with two black spots; fore tarsi white, the two last segments orange 
with four black spots; in the ab. nigropunctata Beth.-Baker (21 d) the forewing bears a terminal series 
of small black dots; in ab. multipursctata ab. nov. (= ab. 2 Hmps.) these terminal spots are larger, and the hind¬ 
wing also has three points at middle of termen. New Guinea. 
C. verticata spec. nov. (21 d). Differs from tibialis F. in the forewing being broader, the termen of the 
S vertical and straight, curved only at tornus. Occurs in the Solomons, the Louisiades, New Guinea, 
Queensland, and Upolu. Type in Tring Museum. 
C. dianae Guen. (21 e). Differs from tibialis F. in the forewing having a series of minute black dots 
just before termen. Described by Guenee from a single specimen from New Holland. The only example 
I have seen, —- from Mackay, Queensland, is smaller and more delicate than any of the foregoing species, and 
appears very distinct. 
Sect. II. Forewings small, with lines and markings. 
C. rejecfa F. (= bimacula Walk.) (21 e). Forewing white; costa with four brown spots indicating the 
origin of subbasal, inner, median, and outer lines; the third prolonged into a short streak, either brown 
or yellow; outer line brownish, or yellow, excurved below costa, dentate lunulate, the teeth forming dark 
points on veins; subterminal line starting from a dull brickred brown-edged blotch, containing two 
white dots on costa, its inner edge slightly indented below costa, its outer sharply indented at vein 7, reaching 
inner margin as a greyish yellow diffuse band; a row of blackish dashes between the veins close before 
termen; a fine yellowish terminal line; fringe white; hindwing white with brown-dotted terminal line. 
The type of rejectaF. was from “India”; that of bimacula Walk, from Hongkong; the description of Fa- 
bricius is vague; that given above applies to bimacula ; this type form occurs in Hainan; — the form stigmata 
Hmps. (21 e) has all the markings less distinct, the subterminal costal blotch rufous, oblong, with a 
single pale spot on costa, and the inner edge not indented; this form, described first from the Nilgiri Hills, 
Madras, occurs also at Travancore and in the Khasia Hills; a third form. — ab. obsolescens ab. nov. 
(21 e) is still less marked; the outer sinuous yellow line is sometimes faintly traceable from a faint yellow 
costal cloud; the black striae before termen are reduced to black scales, and the black costal dots on fore- 
wing and dark dotted terminal line of hindwing are sometimes present, but in some cases the wings 
are altogether without markings; the slightly marked specimens are from Ceylon and Lower Burma; 
those without markings from Ajmere and Belgaum.
