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 hindwing 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. Forewing 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. 
Hindwing 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. 
Antennse black, club whitish beneath; head and body black above, whitish 
beneath. 
Expanse of wings, $ 9, 2 inches.
