There is also a band of yellow spots near the outer margin, which are especially prominent on the hind wings, and a yellow spot occupies the centre of the broad, lobed tail. The caterpillars are prominent, as already stated, and orange- growers consider them among the greatest troubles of the young trees, especially in the nurseries, where a single sj^ecimen may defoliate a shoot in a little time.
