HELIOTHIS ARMIGERA.
This is a very rare moth in England, but is found over the greater part of the world. It expands about one and a half inches. The fore-wings are a brownish yellow, with darker indistinct markings. The hind-wings are lighter yellow in colour, with a dark semi-lunar spot in the middle, and have a dark marginal border. The antennæ are long and fine. The caterpillar was found on the potato-plant and proved to be one of the cannibal species. It fed occasionally on the food provided, but seemed generally to prefer its companions in captivity, feeding at night, and so had to be separated from them. The larva is reddish brown in colour, with a yellowish stripe on the sides, and it is very commonly found in Teneriffe during the early spring months.
