Imago. — Male. Upperside very pale blue with a metallic sheen in certain lights, 

 the basal and costal portions of the forewing and the basal and abdominal portions of 

 the hiudwing suffused with darker blue, darkest at the base and gradually paling 

 outwards. Forewing with a large black spot at the end of the cell, two beyond it near 

 the marginal band, one above the other, a third black spot beneath them and more 

 inwards, a small black dot below that and more inwards still ; a broad black marginal 

 band, well defined, which abruptly stops a little below vein 3, and has below it a black 

 mark on vein 2. Hindwing with a thin, suffused blackish, marginal band, containing 

 suffused black markings in the interspaces, the black spots of the underside showing 

 through the wing. Underside white. Foreioing with all the markings jet black and 

 large ; a transverse spot in the middle of the cell, a larger nearly round spot at the 

 end, a whorl of spots in the upper disc beyond, commencing with a twin spot on the 

 costa, a twin spot below and a little outside, a round spot again below and on the inner 

 side and a small spot again below and still farther inwards, a sub-terminal row of square 

 spots from the costa to interspace l,an anteciliary row of short somewhat lunular marks 

 stopping in the same interspace, and a marginal series of smaller and somewhat triangular 

 spots stopping in the next lower interspace. Hindwing with three large spots on the 

 costa and three bands of large spots across the wing, the first consisting of five, the 

 second and third of seven each, and an anteciliary row, the spots becoming larger 

 hind wards. 



Female. Upperside like the male, but there is an extra spot inside the cell, three 

 sub-apical spots instead of two, and a small spot straight below the hindermost large 

 spot instead of being well on the inner portion of the wing as in the male ; the 

 marginal black band is also broader and is somewhat suffused on its inner side. 

 ■liindicing with all the spots of the underside showing more distinctly and the outer 

 marginal band broader. Underside similar to the male, except for the position of the 

 small spot being directly below the large lowest one, instead of being on its inner 

 side. Cilia of both sexes white. 



Antennte black, club whitish beneath ; head and body black above, whitish 

 beneath. 



Expanse of wings, ^ ?, 2 inches.
