The wingspan is 12–13 mm. The forewings are rather dark brown with the markings ochreous-white. There is a slender median streak from the base, branching at one-fourth into two lines, the upper running to five-sixths but more or less widely interrupted in the middle, the lower running to three-fifths. There is a narrow pointed streak below the fold from the base to one-third and short subdorsal and dorsal lines from the base, as well as a pointed costal streak on the basal third, sometimes partially obsolete. A suffused dark fuscous transverse spot is found from the dorsum before the middle, immediately followed by a white longitudinal streak beneath the fold to the tornus and there is a fine costal line from before the middle, becoming slightly divergent and terminated by a very oblique strigula at four-fifths. From beneath the apex of this a line to the tornus, acutely angulated inwards above the fold. Just beyond these markings is a fine obtusely-angulated blue-leaden-metallic transverse line and there are three indistinct marks on the costa towards the apex, the last edging a black apical dot preceded beneath by a minute blue-leaden-metallic dot. The hindwings are grey, paler in the disc anteriorly.[2]
