This genus includes several pretty large and showy insects, several
of which, have some resemblance, in the wide expansion of their wings
compared with their limited breadth in the direction of the body, to
the genera immediately preceding, while others shew a decided affinity
to _Argynnis_. The greater part of them are natives of America, but
others occur in the eastern countries of the old world. The palpi are
contiguous below, but diverge at the extremity, and terminate in a
slender acicular joint; antennæ with an oblong club; inferior wings
embracing the abdomen; claws simple. The caterpillars appear to be
generally spiny, and to resemble those of _Argynnis_.
