C. serra sp. n. (152 c) is allied to nitida; forewing silvery white, scantily strewn with blackish-brown, serra. 
more densely in a triangular inner-marginal area, with 2 sharply notched black transverse lines, the anterior 
one proceeding from a triangular dark brown costal-marginal spot, the posterior one from a tiny spot in the 
centre of the costal margin, then extending almost parallel to the distal fifth, forming a sharp angle on the 
lowest subcostal branch, from where it runs dentated to the inner margin; it is followed by a red-brown dentate 
line which ends behind the cell in a large dark brown triangular costal-marginal spot containing long black 
wedges which project distally from the brown spot as black notches; before the postmedian line there is another 
indistinct reddish-brown line, a white crescent at the cell-end is composed of turned-up scales; blackish-brown 
arcuate streaks before the margin, small black spots behind them on the veins. Hindwing white, veins and 
margin narrowly brownish, inner margin with brown hair. 2 ^ from Joinville (Brazil), type in the Senckenberg 
Museum. 
C. hymen Dyar (152 d) has longer and narrower forewings than serra, of a silvery grey colour, shaded hymen. 
with brown subbasally in the costal-marginal half, also subterminally except the space between the veins 3 
and 4; the black postmedian line is coherent only in the lower half, with a black longitudinal ray behind it 
between the median branches; a purely white crescent at the cell-end, a brown spot between the veins 4 and5 
near the margin; the marginal line is composed of black angular streaks. Hindwing whitish, brown at the 
distal margin with a white anal spot. British Guiana. 
C. larca Schs. is very near to hymen; forewing white strewn with grey, with a large violettish-brown larca. 
spot near the base of the costal margin as far as into the cell, bordered by fine black lines, the distal one of which 
is dentately continued to the inner margin; the posterior transverse line is partly double, lilac brown shading 
behind it, interrupted below vein 4 and containing black longitudinal streaks. Undulate line purely white. 
Hindwing greyish-brown with white cellular and inner-marginal stripes and a broad darker margin, spotted 
black at the anal angle. French Guiana. 
C. rubiginosa Dogn. is also allied to the preceding species, separated by intensely red-brown irroration rvbiginosa. 
and red-brown markings, so that only the distal margin exhibits the light silvery grey ground-colour; the white 
spot at the cell-end is S-shaped, a white cellular dot before it. The other markings as in the preceding species, 
but more blurred in the brown ground. French Guiana. 
C. infanta Dyar (152 d). Forewing silvery greyish-white, with a red-brown triangular spot subbasally infanta. 
at the costal margin, edged by black lines, a few brown costal-marginal striae behind it; of the postmedian 
line only two spots behind the cell are present and a larger L-shaped streak filled with brown between the 
median nervules; subterminal area brown only in the upper half; undulate line and discal spot white. Hindwing 
brownish with a white postmedian band. Peru, Bolivia. 
C. velha Schs. is somewhat like infanta ; forewing silvery white, scantily strewn with grey, more velha. 
densely at the inner margin, with brown costal-marginal spots, a very large one below them before the centre, all 
finely bordered with black, the middle spot continued to the centre of the inner margin; postmedian line 
double, shaded with brown at the inner margin, in the upper half outside with a purple brown band enclosing 
3 black small triangular spots; marginal line similar to that in the preceding species. Hindwing white, brownish- 
black in the distal half of the costal margin and at the margin. Brazil, Colombia. 
C. finiana Schs. Head and thorax white, intermixed with brown, abdomen white, the 4th and 5th finiana. 
segments brown. Forewing white, strewn with light cinnamon; a brownish-black antemedian area between the 
subcosta and the median vein, bordered by an irregular black line, a feeble brownish shadow in the median 
area, and a white lunar spot at the cross-vein; postmedian line double, the interior portion shadowy, brownish, 
the exterior portion a very fine black line, with a broad sand-brown shadowy spot behind it between 4 and 
the costal margin, bordered outside by the white dentate subterminal line; a dark hook-line between 2 and 3. 
and a brownish spot above the tornus; marginal area between 4 and the apex dark with black marginal 
lunae, white below them. Hindwing white, blackish-brown at the distal margin, with a short curved apical 
line. Expanse of wings: 34 mm. Colombia. 
C. arecosa Drc. (= cacobule $ Dyar) (152 d). The white forewing is strewn with brown and grey, arecosa. 
with a broad brown subbasal band, dying away towards the inner margin, with small brown costal-marginal 
spots and a very large subapical one with a smaller one below it. Hindwing light grey with a brown margin. 
The $, described as cacobule, looks quite different: forewing grey, the brown subbasal band traceable, with 
fine black transverse lines, a yellowish-white cell-end streak and 2 dots before it, with a distinct blackish- 
brown undulate line ending below in 2 small spots. Panama. 
C. torresi Dogn. (= perilleus Schs.) (152 d) is similar, forewing light brownish-grey, with a large torresi. 
brownish-black spot subbasally at the costal margin, and a black undulate line behind it; an angular dark 
grey line in the median area and two light patches in the cell; the irregular black postmedian line is interruptedly 
shaded with brown outside, the undulate line broad white with small irregular black spots before it. Hindwing 
white, broadly dark grey at the distal margin. Brazil, Ecuador.
