This insect so closely resembles _C. Marcellina_ that it is possible
they would still have continued to be confounded, as they were by
the earlier entomologists, had not the different appearance of the
caterpillar indicated their essential distinction. In the male the
surface of the wings is a fine citron-yellow, with a narrow border of
a deeper hue; the fringe of all the wings marked at remote intervals
with small rust-coloured spots. Beneath the colour is red, or
brownish-yellow; the upper wings with a double ferruginous spot at the
extremity of the discoidal cell, and a brownish zig-zag ray towards
the outer margin; the under wings likewise with two rounded discoidal
spots, silvery in the centre, and surrounded by a rust-coloured ring;
there are likewise several undulating brown lines running across the
surface more or less distinctly defined. The female is bright yellow
inclining to orange, the inferior wings much rounded, and having an
orange-coloured fringe interrupted with transverse brown stripes.
The position and appearance of the discoidal spots similar to what has
been described in the male: the under side deep ochre yellow. Body
yellow, with greenish hairs on the thorax; antennæ, and terminal joint
of the palpi, rose-colour mixed with brown.
