The outline of this richly-ornamented insect perfectly corresponds to
that of the preceding species, except that the hinder margin of the
upper wings is scarcely concave. The whole disk is very brilliant blue
with a tinge of green, surrounded by a black border, which is wide and
sinuated on its inner edge in the female, and narrow in the other sex.
The anal angle of each of the hinder wings bears a large blood-red
mark, and the tails are black tipped with white. On the under side the
green hue predominates, and the whole is thickly-powdered as it were
with gold dust, giving it a very rich appearance. Near the middle both
wings are traversed by a distinct black line, angular posteriorly, and
bordered externally by pale blue: behind this, on the under wings,
there is a broad deep red or ferruginous band, paler towards its hinder
edge and sprinkled with blue atoms: the outer margin of all the wings
is darker than the interior. Expansion of the wings about two inches.
