Miletus symethus, the great brownie,[1][2] is a small butterfly found in India[3][4] that belongs to the lycaenids or blues family.

Forewing: the median white patch as on the upperside but larger, its margins less clearly defined, continued posteriorly to the dorsal margin; obscure catenulated (in the form of a chain), incomplete, transverse, white-margined narrow bands, two at base and two or three very short ones above the white median patch on the costal area, from between the outer two of these latter a transverse, zigzag, very slender, somewhat obscure white line crosses the anterior portion of the wing to vein 4; lastly a pre-tornal quadrate brown spot near apex of interspace 1a and an obscure sub-terminal transverse series of slightly lunular small brown spots; the ground colour terminally paler and more ochraceous than on the inner portions of the wing.

The female has the upperside forewings of dark brown; base shaded with greyish brown; the white median patch as in the male, but very much larger, its upper margin irregularly curved; it is spread over the anterior two-thirds of the cell, extends beyond it into the bases of interspaces 4, 5 and 6, and below the cell it occupies the basal four-fifths of interspaces 1 and 2.

Underside, forewing: the median white patch as on the upperside but larger, extending to the dorsal margin and base of cell; base of wing, costal margin above the sub-costal vein and conjoined upper discal obliquely-placed patch greyish brown; apex of wing whitish, termen between veins 1 and 6 broadly stained with rusty; a conspicuous rusty pretornal spot; some obscure white-margined spots at base of cell and along costa, and a transverse sub-terminal series of black dots.

Hindwing: pale ochraceous white, darkening to rusty brown towards the middle of the termen; a subbasal, a median and a discal transverse incomplete macular brown band, each spot in the bands margined on the inner and outer sides by slender black lines; finally a subterminal transverse series of short slender black threads.
