Type species:
dyras Walker.
The most conspicuous feature of the genus is in the fasciation of the
forewing: there are three transverse fasciae just basal to the discal
mark, and three distal to it, the outer two of which double back
subtornally to form a double loop containing a dark central spot, based on
the dorsum. The forewing apex and the angle of the tornus are usually
weakly falcate, and the wing margin is somewhat irregular. The hindwing
tornal area usually contains two dark brown patches, again often
associated with a slightly looped fascia.
The tongue is very short and weak, the halves separated in some species.
In the male genitalia the uncus is usually weakly bifid, sometimes very
broad. The harpe is strongly developed into a sclerotised spur, the valve
otherwise rounded, with a subapical process in a few species. The
transtillae of the valve each have a strong dorsal spine, and are found
centrally so the spines are paired together.
The
larva is granulose with a triangular head; the pupa is somewhat glossy,
rugate, with two small frontal tubercles (Rothschild & Jordan, 1903).
The majority of species are found in the Oriental tropics and subtropics,
extending north into temperate eastern Asia and with one southern European
and west Asian species (D'Abrera, 1986: 80). The genus has its easterly
limits in the southern Moluccas and Tenimber.
