spots are almost exactly parallel to the outer border, that in the lowest
median interspace with its outer border at an interspace distance from
it; with the exception of that in the lowest subcostal interspace, they
are each surmounted interiorly by a much smaller circular light spot, the
centre of which is near the circumference of the larger spot, so as to
infringe upon it; with the exception of the uppermost, which is nearly as
large as the spot on whose summit it is placed, the light spots are of
nearly equal size and about one-third of an interspace in diameter; or if
anything the two lower, seated on the largest spots, are smaller than the
others; the wing must have been wrinkled between the nervules next the
outer border, as shown by the dark lines running from the border to the
centre of the dark spots. The outer edge and the apex of the inner are
uniformly dusky and rather lighter than the other dark parts of the wing;
the fringe is evidently lost.
The hind wing is very dark at the base, like the fore wing, nearly as
far as the extreme tip of the cell; this dark area merges gradually into
a lighter portion, which crosses the wing as a very broad equal band
having its outer limit at a narrow, dark, regular belt, with ill defined
outline, which crosses the wing subparallel to the general course of the
outer border a little within the middle of the outer half of the wing;
within this broad light band are two narrow transverse powdery streaks
of dark scales, one extending from the extreme tip of the cell, and
broadening a little in its course, running in a curve opening inward to
the inner border; the other starting from the same point in an opposite
direction, and passing in a sinuous course, with varying width, toward
the middle of the basal two-thirds of the upper subcostal nervule,
hardly separate from the outer limits of the dark base of the wing. The
darkest part of the narrow band in the middle of the outer half of the
wing has a regular curve and strikes the borders in the middle of their
outer halves; there is a submarginal slender dark streak, separated by
scarcely more than its own width from the outer border, becoming narrower
toward the costal and inner borders, and especially towards the costal;
it is broken at the upper median nervule, where the upper portion joins
a second broader band, separated by a space nearly equal to itself from
the submarginal band; this leaves a nearly equal light band in the outer
part of the wing, broadest above and reaching from the costal border,
almost to the inner; along the middle of this belt is a series of six
round dark spots and ocelli, one in each of the interspaces excepting
the costo-subcostal; the largest is in the lower median interspace, and
is a spot nearly as broad as the interspace, deepening toward the centre
to a black pupil; the next largest, in the upper median interspace, is
an ocellus with a black pupil, immediately followed by a pale annulus,
