porrect, but they may also be erect; they are short or extending just beyond the forehead. The forehead is 
broad and projecting round; the $ antennae are ciliated in tufts; tibial spurs of middle length; abdomen above 
rather roughly haired. The forewings are long and narrow, in the strong, with secondary sexual marks either 
in the shape of scent-scale spots, hairlocks or stunted veins, whereas the $$ show a normal venation. A charac¬ 
teristic mark of the genus is the discocellular being angled in the middle on both wings, the middle radial rising 
close below this angle and being rudimentarily developed on the hind wing. The 3rd and 4th subcostal veins 
are usually absent in the <$, whilst in the $ they are petiolecl with the 5th; the two upper subcostal veins rise 
separately from the cell. On the hindwing the 3rd radial and 1st median vein rise on a long footstalk or 
are entirely fused, and the subcostal is also petioled with the 1st radial. 
The larvae live on lichens like most of the Lithosiids; they are, as far as we know, cylindrical, with 
a small head and provided with hair-tufts on elevated warts. The pupation takes place in a network with 
extremely wide meshes. The pupa is immobile. 
The imagines are occasionally met with on flowers, they are more frequently scared up from bushes, 
as they generally fly at night. They are met with all the year round. As to the palearctic forms vide Vol. IT, 
p. 61 and 62. 
C. peregrina Wkr. (= puella Moore). Forewings white. Red are the palpi, forehead, borders of 
the collar, bands on the thorax and shoulder-covers, legs and 4 transverse stripes on the forewing: one at 
the base, one each before and behind the middle, and one at the margin; the two middle ones are bordered 
with black on the averted sides; at the cell-end there are 3 black dots in the the $ has only one. Hindwings 
and abdomen tinted red, in the $ more intensely so. The <$, like the following species, shows above on the hindwing 
at the costal margin a brown androconium, another one at the cell-end of the forewing at the costal margin. -— 
arguta form. nov. from Pirmad shows much broader red transverse stripes with much more prominent black 
borders. From India as far as Ceylon. 
C. catarhoda Hmps. (16 f) is very similar, but easily distinguishable by the absence of the black 
borders of the two red median lines. Assam, Burma. 
C. rubrifasciata Druce from North Celebes numbers among the largest species (expanse of wings: 
52 mm). Thorax brick-red, abdomen blackish-brown, beneath yellowish-white. The white forewing is brick-red 
at the base, bordered with black; there are ante- and postmedian, broad, brick-red transverse bands bordered 
with black; at the cell-end a black spot; at the margin there is a large, red spot bordered with black. Hindwings 
brownish with white fringes. 
C. puella Drury (Vol. II, t. 12 a) looks a little like peregrina, the red transverse stripes are finer, 
and the hindwing shows no androconium. Distributed in India as far as Ceylon, and in Cashmir it extends 
into the palearctic region. 
C. alborosea Wkr. (= pallens Btlr., Duclgeoni Hmps.) (16 g) is very much like puella, but the two 
middle transverse stripes are not bordered with black; palpi brown; behind the posterior transverse stripe 
towards the costal margin a yellowish spot which is black in f. quadrinotata Wkr. -— In javanica form. nov. 
the hindwings are not pink, but of a pure white. Hongkong, Sikkim, Assam, Java. 
C. subalba Wil. $ head and thorax white, the latter with 3 reddish bands the posterior one of which 
is short; abdomen whitish, with a reddish tint before the white anal ring. Forewing white with 4 reddish bands; 
the subbasal band does not reach the proximal margin; the antemedian one is almost straight, but at the costa it 
slightly turns inwards; the postmedian band is distally curved below the cell; the submedian one curved and 
almost parallel to the margin. The costal pad with a black §pot at its distal margin and 2 black spots below 
it, the distal one of them linear. Hindwing white with a reddish hue on it except in the costal area; at 
the cell-end a feebly dark, small luna; fringes white. Beneath white, costa of forewing with a reddish streak 
from the base to the sexual spot; the reddish band only feebly shows through; the small luna at the cell-end 
of the hindwing is more distinct than above. $ similar, but with 3 black spots; the bands are considerably nar¬ 
rower, and the antemedian one is above the middle feebly angled proximally. 42, $ 52 mm. Taken in May, 
in Formosa. 
C. saulia Swinh. from Paitan is very similar, according to the description; it differs by yellow antennae, 
a black terminal joint of the red palpi, a larger black cell-spot, and fine red transverse lines. 
C. distincta Roihsch. which was described according to a $ of a length of forewings of 25 mm, lias 
pale brown antennae; thorax and head are white, collar and shoulder-covers with red bands; abdomen salmon- 
coloured pink. The white forewing exhibits the usual 4 red transverse stripes; that next to the margin is of a 
much paler red; at the cell-end 3 small black spots. Hindwings pink, costal margin, apex and fringes white.
