Larva—Is* stage. July 28th. Length Head rounded, not very large, black,retracted within the very wide prothoracic segment, which has on each side a largeblack tubercle, larger than those on the abdominal segments; between the twotubercles is a median dark patch. On the two succeeding thoracic segments thetubercles are small. On each abdominal segment are two dorsal and two lateral blacktubercles on each side. From the tubercles arise loose tufts of tawny brown and palehairs, of unequal length, some twice as long as the body, so that the larva lookssomewhat like an arctian or a
