A small Ichneumon fly, Microdus carinoides Cresson, attacks this bud-worm, depositing an egg in the body of each cater- pillar, which, hatching, produces a footless maggot, that lives within the body of the caterpillar until it is about ready to become a chrysalis, when the maggot issues from its body and the larva dies. The parasite spins within the silken case of its host a tough white cocoon about one-fourth of an inch long, from which the perfect fly issues in about a fortnight. Where these insects are very troublesome they may be de- stroyed by syringing the trees with Paris-green or London- purple mixed with water, in the proportion of one or two teaspoonfuls of the poison to two gallons of water. Their numbers may also be lessened by hand-picking, gathering them while still in their burrows near the tops of the twigs. No. 40.—The Green Apple-leaf-tyer. Teras Cinderella (Riley).

It is a very nimble little creature, and when dis- turbed wriggles quickly out of its case and drops to the ground. The larva changes to a brown chrysalis (6, Fig. 95) within the fold of the leaf, which is lined with silk.
