setaceous. Tongue very small and spiral. Thorax and abdomen yellow buff
colour; as are all the wings in general. The anterior having a bar of
brown red colour, which begins at the tips, and runs across the wings,
almost to the middle of the posterior edge; occupying all that space
along the external margin. At the base is a small cloud of the same
colour, but much fainter. Posterior wings with a broad marginal bar of
the same brown red. A small faint line likewise crosses these wings. The

sprinkled over the brown bars.
