About Cyana peregrina (Walker, 1854)
Males of Cyana peregrina (Walker, 1854) have white palpi and scarlet lower sections of the frons. The tegulae are edged with scarlet, and scarlet bands cross the thorax, patagia, and meta-thorax, with the band on the meta-thorax being less intensely scarlet. The fore coxae, mid femora, and hind tibiae and femora are white, and the abdomen is tinged with scarlet on the upper surface, except towards the base. On the forewings, a subbasal scarlet line expands at the costa. An ante-medial line bends inward toward the costa, and has a slight black edging on its inner side. A postmedial line has slight black edging on its outer side, and bends inward above vein three. There is one black spot in the upper angle of the cell and two black spots on the discocellulars. A brownish mark sits beyond the postmedial line below the costa, and a terminal scarlet band runs from the apex to the postmedial line. On the hindwings, the inner area and termen are tinged with scarlet.
Females of Cyana peregrina (Walker, 1854) have one black spot at the end of the forewing cell. The black edging on the ante-medial and postmedial lines is prominent. The postmedial line is oblique across its entire length, and the terminal scarlet line only runs just around the apex. The hindwings are pale crimson, with white cilia. The underside of the forewing is pale crimson.
