The collector's bag should contain several empty tins of all shapes and sizes, to carry the hundred and one things found in a day's collecting, such as live larvae, cocoons, galls, eggs, &c.

These delicate little creatures are taken home alive, and can be killed in a jar and mounted while quite fresh.
