The former description of this species was made from a single old specimen, on which no tufts were visible (having no doubt, been removed in setting the specimen, which was, however, otherwise undenuded.) Since the publication of that description, I have bred the species, and the tufts in the fresh specimen are distinct, and the insect unquestionably belongs to this genus. The following description of the fresh specimen is more accurate than the preceding one. I have changed the specific name, giving it that of the food-plant.
