C. lemoulti Dogn. (= hollandi Schs.) (152 b) is another variation of the preceding species with 
purely white forewings with 2 very large and 2 small blackish-brown costal-marginal spots, without any other 
markings except a few brown scales at the anal angle. Hindwing white. The unknown $ may be grey and 
very different. French Guiana. 
C. tenuis Schs. (= costaricensis Dogn.) (152 e) is a smaller not rare species, marked somewhat 
like larca : forewing dull silvery white, scantily strewn with black, with fine black median and postmedian 
lines, with small brownish strigiform spots at the costal margin between them; behind the postmedian line 
follows a series of large light brown spots distally centred with black, interrupted between the veins 3 and 4; 
a fine black scalariform line on the margin. Hindwing white with a narrow brownish distal margin. Widely 
distributed from Mexico to Brazil. The $ shows the whole centre of the wing and the subterminal area darkened 
blackish-brown with a slight pink tinge. 
C. modulata Schs. (152 e) is allied to tenuis, forewing dark grey, whitish at the inner margin at the 
base and in the middle, with fine black transverse lines and a white undulate line which is straight in the upper 
half, then twice interrupted; the black marginal line is straight in the upper half, bordered with white inside, 
with brown outside, then undulate, white outside. Hindwing white, brownish at the margin, quite brown in 
the $. Costa Rica. 
C. luculemta Schs. (152 e). Forewing light brown, strewn with blackish below the basal third of the 
cell, with a double black antemedian transverse line filled with white; the median area behind it is broad w’hite, 
traversed by dentate black lines and distally bordered by a double postmedian line which is removed far 
inwards on the upper median nervule, so that the median area ends very narrow at the inner margin; black 
subterminal wedges in the upper half and small brown spots in the lower half. Hindwing white, black at the 
distal margin. Costa Rica. 
C. peirreta Dogn. Forewing bluish-grey, white at the base and in the centre of the margin, with fine 
double transverse lines and a white cell-end streak surrounded with brown. Hindwing white with a small black 
anal spot. Expanse of wings: 35 mm. Trinidad. 
C. hibrida Schs. Forewing grey, with a brown tinge before the centre, the anterior double transverse 
line filled with lighter brown, a white streak at the cell-end and a blackish-brown shadow behind it; the 
posterior transverse line is velvety blackish-brown shaded with brownish behind it; the distal margin behind 
the white undulate line is whitish dusted with brown, most densely so in the upper half. Hindwing whitish, 
greyish-brown at the margin. The $ differs in a velvety black undulate line bordered with white outside, and 
darker hind wings. Costa Rica. 
C. multifida Schs. Basal half of fore wing dark brown enclosing a darker transverse line which is double 
at the costal margin; a dark brown cellular spot is bordered with reddish-yellow on both sides, the posterior 
transverse line is velvety black, distally shaded with brown in the upper half, bordered with white in the lower 
half, with a velvety black longitudinal streak behind it between the veins 4 and 6, and a dark spot below it; 
a dark brown submarginal shadow contains black streaks in the upper half, a white dentate line behind 
them. Hindwing white with brown marginal line and spots at the apex and anal angle. Expanse of wings: 
30 mm. French Guiana. 
C. chorista Schs. Forewing white, strewn with grey, with brown costal-marginal spots and a black 
straight antemedian line bordered with white on both sides, a white streak at the cross-vein; the black post¬ 
median line is shaded with brown distally, broadest above the inner margin and here with a black longitudinal 
streak behind it; the whitish undulate line is broad. Hindwing whitish, brownish at the margin. Expanse 
of wings: 38 mm. Guatemala. 
C. comana Dogn. Forewing white, dusted with brown and strewn with yellow, with a darker basal 
band bordered with yellow, and a white cell end dot; behind the brown postmedian line follows a broad brownish- 
black band, interrupted by a yellow spot between the veins 3 and 4; black, white-dusted streaks are in the 
brown marginal area between the yellow veins. Hindwing blackish, fringe light. Expanse of wings: 36 mm. 
Described from a $ from French Guiana. 
C. flavodiscata Dogn. (= distinguenda Rothsch.) (152 e) is easily recognizable by the broad yellow 
discal streak on the light yellowish-grey forewing with very sinuate chestnut-brown subterminal shading. 
Hindwing grey, whitish in the costal-marginal half. French Guiana. 
C. ocreata Dogn. (152 e) has brownish ochreous forewings strewn with lilac grey, with indistinctly 
double transverse lines and a white ring-macula and reniform macula, surrounded by lilac; the broad sub¬ 
terminal band is light lilac grey, bordered inside by a black line. Hindwing white with a blackish marginal 
band. Expanse of wings: 43 mm. Bolivia (Songo). 
C. collema Schs. (= praelauta Schs.). The basal third of the costal margin on the forewing 
and the cell are whitish, strewn with brown, the rest brown excepting the marginal area which is 
white above the upper median branch and strewn with brown, transverse lines black, the posterior
