Introduction
The genus Lethe is composed of 112 species, most of which are found in temperate forests in Asia, although there is one species endemic to Sulawesi, another endemic to Java. Several of the species are very localised, being confined to the forests of particular mountains, but others are widespread. The commonest and most widely distributed species is rohria, which is found from Afghanistan to China, and south to Java, Bali and Lombok.
Lethe species typically have sombre earthy brown uppersides, although a few such as europa have prominent white diagonal bands on their forewings. In some such as sinorix there is a series of dark ocelli on the hindwings, set within a band of suffused orange.
The undersides of all species are much more strongly marked than the upper surface, and feature a series of 7 prominent submarginal ocelli. Several species including baladeva, albolineata, yunnana, argentata, andersoni and luteofasciata have striking white, silver or yellowish streaks underneath but these are barely visible on the upper surface.
Lethe argentata is endemic to China.
