white underneath. Wings white. Forewing: the costa finely light brown, a greyish basal shade on inner margin; 
a greyish medial shade from cell to inner margin; a greyish postmedial shade not extending above vein 5, but 
continued as two fine brownish lines from vein 4 to costa; an olivaceous spot on the inner line at vein 5; outer 
margin broadly shaded with grey; a large terminal olivaceous patch from veins 5 to 7; cilia olivaceous. 
Hindwing shaded with grey below vein 4; the inner margin light brown and olivaceous. Expanse: 23 mm.

C. amoena Dogn. (89 c). Male: Frons light buff. Collar white. Thorax buffy olive. Abdomen above 
tawny olive, laterally and below white. Wings white. Forewing: the lines greyisch olive, the costal edge dark 
olive buff; an outcurved antemedial line followed by a double medial parallel line; a double slightly outcurved 
postmedial line, closely followed by a short narrow band, and from below 6 by an expanding shade suffusing 
with a broad terminal shade, this latter also upbent to vein 7 and connected with costa by a fine line. Hindwing: 
three short lines medially on inner margin and cilia, and some similar darker lines postmedially. Hindwing 
below with a dark olive elongated spot below vein 2, cut by a fine white line. Expanse: 29 mm. Sao Paulo 
de Olivenga, Amazons. When faded tlje ^markings become paler and more of an olive buff. 
C. similis Fldr. Male: Body and wings as in amoena but the white space on forewing between medial 
and postmedial lines narrower and the termen with more white above tornus. Expanse: 29 mm. Locality 
unknown. If Felder’s figure is not correct the species will probably have priority over amoena. 
C. klagesi Ware. Female: Forewing: very pale mealy green, thinly scaled and semitransparent, stained 
with dull rufous olive as far as the submarginal line, which is irregularly waved and Emulate, from costa 
shortly before apex to anal angle, forming a strong sinus inwards between veins 3 and 4; just before the edge 
of this stain a slightly darker fascia can be traced, the edges of which are marked with darker on the veins; 
the marginal area, a narrow costal space, and the discocellular streak remain of the pale greenish ground-colour; 
cilia pale green slightly mottled with darker; inner margin with darker rufous olive marks. Hindwing: pale 
green, with the inner margin and a curved submarginal line rufous olive. Underside pale green; the forewings 
with an opalescent pink sheen beneath the stained area above; hindwings with a double rufous blotch where 
the submarginal line crosses the submedian fold. Head, shoulders, and patagia pale green; abdomen and tips 
of patagia rufous olive. Expanse: 30 mm. Suapure, Caura River, Venezuela. This species is unknown to me; 
the genus AgriocMora Ware, has been created for it. 
C. am inula Dec. This species is unknown to me. '‘Forewing and hindwing quite hyaline; the costal, 
outer, and inner margins and the veins yellow; the base of the costal margin white; the hindwing with a small 
black spot on the inner margin a little above the anal angle. The head greyish; collar yellow; thorax and abdomen 
dark reddish brown; antennae and legs yellowish brown. Expanse: F /4 inch. S.E. Brazil. A distinct species, 
allied to opalina Bull 
C. aerila sp. n. (89 c). Female: Head and collar pale drab grey. Thorax and abdomen drab grey. Fore¬

buff; postmedial outcurved, lunular, closely followed by a finer parallel line and four small quadrate spots edged 
with white; some olive yellow before postmedial and between the lines irrorated with golden primrose-yellow 
scales; below vein 4 the lines are lunular wavy and very fine. Hindwing: costal margin broadly whitish, then 
light cinnamon drab suffused with fuscous drab on termen; a faint dark medial line; inner margin light ochraceous 
buff crossed by cinnamon and white lines above anal angle. Hind wing below buff-white irrorated with hair 
brown on outer half; postmedial hair double, lunular. Expanse: 30 -32 mm. Sao Paulo de Olivenga; Upper
