Common.
A small butterfly, 38–44 mm in wingspan. The upper forewing in both sexes has a pale elongated oval discal patch. This may be larger and more diffuse in females. The butterflies are speckled below.
Male upperside: brown. Forewing: an elongate oval pale patch beyond apex of cell. Hindwing: uniform, immaculate. Underside: dull white. Both forewings and hindwings with numerous short, slender, transverse strigae and minute dots, brown. Forewing: dorsal area near base below the cell but not further outwards more or less free of spots and strigae; a narrow brown transverse spot across cell near the base, another across the middle, and a third of the apex of the same; a postdiscal, sinuate, irregular, macular, transverse, broad brownish line followed by a subterminal series of similarly-coloured minute spots. Hindwing: two or three very broken similar transverse broad curved lines, sometimes clearly marked and the detached portions indicating a definite band, in other specimens very irregular and out of line with one another; this is followed by a subterminal series of minute brown dots as on the forewing. Antenna, head, thorax and abdomen concolorous with the wings; beneath: the palpi, thorax and abdomen more or less speckled with whitish.
Female. Similar, but in all specimens I have seen invariably smaller. Underside: ground colour of the same brown shade as in the male, the pale postcellular patch on forewing replaced by a diffuse medial patch that spreads into the cell. Hindwing: as in the male. Underside: also similar in ground colour and markings to that of the male, but the markings broader, more clearly defined, and less macular. Antenna, head, thorax and abdomen as in the male.
