Miletus boisduvali, the common brownie,[1][2] is a small but striking butterfly found in India and Myanmar[3][4] that belongs to the lycaenids or blues family.

The upper forewing in both sexes has an obscure narrow curved white discal band, the lower spots composing it are well separated.

Forewing: a pale whitish, irregular, somewhat diffuse discal patch; cell crossed by six very slender obscure sinuate white lines, that give the cell the appearance of being crossed by three short brown bands; an irregular postdiscal sinuate transverse series of brown lunules of a shade slightly darker than the ground colour, those on the anterior portion of the wing are very slender and thread-like, those posteriorly broad and formed into somewhat annular transverse spots, the lower spots cross the discal whitish area; a subterminal series of black dots continued along the apical half of the costa.

Hindwing: crossed by more or less obscure, catenulated, dark brown, interrupted bands that are margined on the inner and outer sides by snort, thread-like, darker, sinuate lines; a short, maculate, dark purple, transverse band from the middle of the dorsum to vein 4; and a subterminal series of minute black dots that is continued both subcostally and subdorsally to the base of the wing.

On the underside the purplish-brown gloss on the hindwing is restricted to a small area near the middle of the termen, the rest of the ground colour of the wing is dull brown.
