_Arpidea Chorinæa, with Caterpiller & Crysalis._
Surinam.
_Lizars sc._]
The colour of the surface in the above species is deep brown, darkest
on the upper wings, which have a wide fulvous sinuated band, rather
beyond the middle, commencing at the costa and reaching nearly to the
opposite side, where it terminates in a point: the costa is likewise
yellowish, and towards the apex there is a round white spot. Posterior
wings of a lighter hue round the margin than on the disk, and near the
hinder extremity an indistinct row of whitish points. On the under side
all the wings are light brown and ash colour, covered with short waved
lines of dark brown, and bearing several continuous transverse bands of
the same colour, and towards the hinder margin of the inferior pair a
row of pale rounded spots. Body brown; prothorax with a fulvous mark.
The caterpillar is very beautifully coloured. The body is reddish,
inclining to violet, the sides of the belly and the legs dull yellow.
Along the back there is a broad yellow band formed of confluent
lozenge-shaped spots, each of them having a dusky line in the centre:
head ferruginous, bordered and rayed with yellow. The anal fork is
grey, with black ciliæ. This caterpillar feeds on the leaves of the
sugar-cane, and changes into a pale brown chrysalis dotted with black,
from which the butterfly emerges in about eleven days. The insect is a
native of Surinam.
