# Lethe rohria

Lethe rohria, the common treebrown, is a species of satyrine butterfly found in Asia.

## Description

Males and females: Upperside van Dyke brown, slightly darker, especially in the female, towards apex of forewing.

Male. Forewing: a costal and two preapical spots white. Hindwing: the ocelli (eyespots) of the underside showing through, sometimes forming two or three obscure black spots; two slender subterminal black lines. Underside paler, shaded with dark brown. Forewing: narrow subbasal and outer cellular transverse sinuous white lines; an irregular broad discal and a narrower postdiscal band white, forming a V, the latter bearing a series of four blind, dusky-black, fulvous-ringed ocelli; the two preapical white spots as on the upperside. Distinct slender subterminal whitish and broader terminal ochraceous lines. Hindwing: a subbasal transverse sinuous white line; a postdiscal arched series of six black ocelli, their centres disintegrated, their inner ring ochraceous, outer brown, and the whole series bordered inwardly and outwardly by lilacine (lilac-coloured) white lines; finally a slender white subterminal and a broader ochraceous terminal line as on the forewing.

Female upperside differs in having a broad, oblique, white, discal band on the forewing and a spot below its posterior end in interspace 1, the inner border of the band bi-emarginate, the outer irregularly sinuous. Underside as in the male, but the markings more pronounced, the white discal band on forewing very prominent. Antennae, head, thorax and abdomen brown; antennae preapically black, at apex ochraceous.
