€„ elegans Schs. (167 h). Small, light grey with a brownish black costal-marginal border, the inner- 
marginal part shaded with brownish, the wing more dotted than striated; marginal marking blackish brown, 
the lower part with a circular bluish-white intermixture with a black central dot, which when the wings are 
closed must look like a pair of false eyes. Veins 7 and 8 of forewing separated, 9 and 10 on a short stalk, 11 
from the middle of the areole. 2 are before me. Brazil: Castro (Parana) and Sao Paulo. 
C. striolata Schs. (169 i). A small species, only 1 $, light grey, almost white, but the specimen appears 
to be faded; a black marking in the centre of the costal margin, a double brown submedian spot in the median 
area; a large brown spot fills the apex more or less, and another spot is in the middle of the distal margin; 
wings scantily dotted brown. Hindwing brown, white along the costal margin. Vein 7 of forewing from the 
discal cell, 8 from the areole, 9 and 10 separated from its apex, 11 from the middle, all the veins free. (Brazil 
(Sao Paulo). 
C„ marmorata Schs. (167 h). Forewing yellowish, with a slight golden gloss, many small dark brown 
spots along the costal margin and on both sides of the median vein, the latter ones roundish extending to % 
of the wing; apex with a slight brassy gloss, with 3 light brown bands. Hindwing light brown. Forewing: vein 
7 from the discal cell, 8 from the areole, 9 and 10 from its apex, and J1 from before the middle, all the veins 
free. French Guiana. 
C, manes Drc. (167 h) is not at hand. Dime ids figure shows a larger form allied with marmorata , without 
spots, all the markings composed of transverse striae, the apex similar. Panama. 
C. niveogrisea Schs. (183 a). Thorax and the outermost base of the forewing white; forewing dark grey, 
indistinctly striated, a few accumulated white dots in the discal area and along the costal margin; marginal 
area yellowish white, enclosing a brown more or less interrupted bow, the yellow before it somewhat darkened. 
Hindwing yellowish white or blackish. Vein 7 of forewing from the discal cell, 8 from the areole, 9 and 10 on 
a short stalk from its apex, 11 from the basal third. I have not seen any $. Guiana, Venezuela, and Costa Rica. 
C. siigripemiat?. Dgn. (183 a). Thorax and base of forewing white. Forewing snioothly scaled grey, 
distinctly reticulated darker; marginal sjDot yellow with a coherent brownish black arcuate margin, a yellow 
stripe at the apex and a black patch above it. Forewing: 7 and 8 from the areole, 9 and 10 on a short stalk, 
11 from the basal third. Hindwing blackish. Both sexes before me. Panama; French Guiana; Brazil (Amazons). 
C. notodontoides Schs. (181 g). Forewing narrow, with parallel margins, pointed in the ; thorax white, 
also the base of the forewing in the $, not so in the <$; the centre of the forewing yellowish white, basally shaded 
with brown, also behind the centre, passing over into black, the marginal area reticularly dotted on the yellowish 
white ground. Hindwing of $ tinged white with dark veins, of $ dusted brown on the yellowish ground. Veins 
7 and 8 from the areole, 9 and 10 on a moderately long stalk, 11 from the basal third of the areole. Brazil 
(Rio de Janeiro and Joinville). 
C. philobia Drc. (181 g). Forewing dingy white, tinged with yellow along the costal margin, slightly 
speckled; 3 large grey spots in the median area, and 2 large round brownish black coherent spots obliquely 
below the apex. Veins 7—11 of forewing from the areole, 9 and 10 together from the apex, 11 from the basal 
third. Mexico, Panama, Ecuador (Zaruma). 
C. praeclara Schs. (== ockendeni Drc.) (181 g). Forewing dingy white with brown transverse striae 
and 3 or 4 broad irregular leaden glossy stripes; 2 large round brown spots in the marginal area are sometimes 
confluent {ockendeni). Veins 7—10 of forewing separately from the areole, only in one specimen 8 and 9 together. 
The $ is not at hand. Brazil, Bolivia. 
C. bistellata Dgn. Only doubtfully different from praeclara, the lead-coloured bands are narrower and 
of a less intense leaden gloss, less contrasting, the marginal spots browner, the neuration the same. Both sexes 
of this form at hand. French Guiana. 
* 
C. alfarae Schs. (183 a). Forewing dingy white, densely striated brown and occasionally with small 
spots of a bronze gloss, a round spot before the apex, one below it is not rounded, but variable, distorted; more 
or less distinct spots also along the submedian area. Forewing: vein 7 from the areole, 8 and 9 on a rather 
long stalk. 10 and 11 from the apex of the areole; $ not at hand. Guatemala; Costa Rica; Panama. 
C, rotursdopuncta Schs. (183 a). A small species, suffused with reddish brown except the anal area, a 
small round brown spot before the apex; the submedian area shows reddish spots in the middle and one spot 
at the inner margin. Forewing: 7 10 from the areole, 8 and 9 on a rather short long stalk, 7 connected with 
the base of the stalk; this obliterates the difference between Trigena and Cossula, but I believe there cannot 
be any mistaking. Brazil.
