Type species: variegata
The facies above is a
deep emerald green, grading yellower towards the forewing apex where there is
also a narrow marginal red zone in some species. There are pale fasciae of
variable intensity, but a feature in almost all species is a greater or lesser
degree of untidy pepper-and-salt clouding in the marginal zone. The underside is
paler: in some species the hindwing is almost white with, anteriorly, a black
border (see C. xeromeris Prout
). The male antennae are
narrowly bipectinate to about four-fifths.
There is a pair of setal
patches on the male third sternite. The eighth sternite terminates in a bifid
structure. The socii are robust, set apart from each other by a broad, sometimes
U-shaped sclerite on which is based the slender, digitate uncus. The valves are
elongate, often slender, costally sclerotised, ventrally weak and laminate.
There are large coremata.
The ovipositor lobes of
the female are elongate, tapering, acute. The lamella postvaginalis is
disc-like, not much broader than the ostium. In the Bornean species, the bursa
is spindle-shaped, slightly fluted and scobinate towards the base but lacking a
signum. It is set on a ductus half its length, but the genitalia of the type
species are less modified.
The genus is entirely
Oriental, with C. xeromeris the most southerly representative.
