C. ophrydina Drc. {— picosa Dogn.) (33 k) is a widely distributed common species having the 
antennae provided with ciliary pencils, similar to the following. Forewings white, spotted black, kindwings 
towards the margins brownish. Beneath the $ has a hairy costal fold of the forewing and a hair-tuft on the 
inner-marginal vein, the hindwing exhibits behind the cell a fold, being on both sides hairy, between the upper 
radial veins. Expanse of wings: 24 mm. Mexico; Guatemala; Ecuador. 
C. maimorata Sells. (33 i) has doubly combed antennae. Body and forewings white, the latter with 
red-brown and bluish-grey spots and a black, distally greyish-brown, post-median undulate line. Hindwing 
with a brownish marginal band. Expanse of wings: 20 mm. Brazil. 
C. fuscipes Grt. is one-coloured brownish-black, on the forewings semi-diaphanous, strewn with dark 
scales. Expanse of wings: 22 mm. United States, Arizona. 
C. acropera Jones (36 c) has likewise combed antennae, and is sufficiently recognizable by the apex 
of the forewing being pointed in the shape of a sickle, with another projection in the middle of the margin. Body 
greyish-brown, abdomen lighter. Forewings white, dusted brownish, at the costal margin, apex and marginal area 
darker, with 3 irregularly undulated, brown transverse lines and a small black discal spot. Fringes light, at 
the apex, the middle of the margin and the anal angle blackish. Hindwings white. Expanse of wings: 20 mm. 
Brazil: Castro (Parana). 
C. cincinnata Schs. (33 1) has the same scent-markings of the forewings, on the hindwing the whole 
cell above is covered with yellow scent-scales. Body dark brown, mixed with white on the head and thorax. 
Forewings white, thickly strewn with blackish-brown. Median area in the inner-marginal half more densely 
dusted with small black spots, and a postmedian dentate transverse line. Hindwings blackish-brown, in the 
costal half more yellowish-white. The $ with a white anal tuft has more purely white forewings, without any 
brown dusting, and quite dark hindwings. Expanse of wings: 20 to 22 mm. Costa Rica. 
C. alembis Dyar (33 k) shows beneath the same secondary sexual marks as the preceding species 
and is also above very similar, but the costal margin is not so very convex. On the forewing there is a very 
prominently black bent antemedian band, and in the middle a band composed of spots. Expanse of wings: 
21 mm. Mexico. 
C. leisova Dyar (331) has the same under surface and likewise a similar upper surface; the forewing 
is very much suffused with red-brown in the inner-marginal area; here the cell of the hindwing above also 
exhibits yellow scent-scales; the hindwings are otherwise much lighter, almost white, only at the margin brownish. 
Expanse of wings: 22 mm. Mexico. 
C. leopardina Schs. (331) is greyish-white on the forewings, with numerous rows of black spots. The 
species is easily recognizable by the submedian fold being coloured orange in the middle. The whitish hindwings 
are brownish towards the margin. Expanse of wings: 24 mm. Costa Rica. 
C. reticulata Eothsch. (33 1) is easily recognized by the neat, black, postmedian venation being edged 
by fine black transverse lines. Abdomen dark with an ochreous-yellow anal tuft. Expanse of wings: 18 mm. 
Peru. 
C. albata Pack. {= albida Wkr., cana W kr., irrorata Edw., patella Drc., philodina Drc.) (331) is 
an extremely common and widely distributed animal and very variable. White, anterior body suffused with 
brownish, abdomen dark-banded. Forewing with numerous small black spots being arranged to transverse 
lines behind the middle, before the middle with two fine black transverse lines. — In the form: umbrata Pack. 
there appears a median shade dusted dark brown. The whitish hindwings exhibit a small, indistinct discal 
spot, traces of a dark line behind it and small faint spots before the margin. Expanse of wings: 22 to 28 mm. 
Through the whole of North America and Mexico as far as Costa Rica. — The larva is whitish green, with fine 
hair, and a dark brown head. 
C. urucata Dogn. (33 1). Forewings very prominently dusted light red-brown in the lower cell-half, 
below it and behind it; otherwise strewn with black scales, and with a broad, black, curved antemedian band 
before the black anterior transverse line; in and behind the middle there are besides brownish transverse lines, 
and before the margin a black macular band. Hindwings yellowish-white. Expanse of wings: 24 mm. Costa Rica. 
C. maculata Rotlisch. (331) is a tiny animal, easily recognizable by the broad,'- blackish-brown 
antemedian band of a silvery blue lustre, and two large, similar spots in and behind the cell. Hindwings blackish- 
brown. It was described as Disoidemata. Expanse of wings: 14 mm. Peru. 
C. lactea Stretch. (33 1). This species, described as bisthene, was formerly inserted in Illice. It is quite 
white, palpi black, antennae brown. The forewings exhibit single, small, brownish-grey spots before, in and 
behind the middle. The under surface is dusted brownish-grey. Expanse of wings: 18 mm. California. 
C. brunneomedia Schs. (34 m) [is to be recognized by the roughly haired costal margin projecting 
in the middle in the below the costal margin on the upper surface a roughly haired spot; on the under surface 
the usual hairy subcostal fold and a long hair-pencil on the proximal margin are present. The grey forewings,
