On June 7, the whole insect ap- peared to be getting darker, which gradually increased until June 10, when it had assumed the permanent colouring of the imago.

It appeared to have been completely exhausted by its violent exertions on May 5, for it did not again ex- hibit the least signs of life until June 15; when it began to move its legs slightly, and strove to open its mandibles, also slightly moving its palpi, which were protruded from the cavity beneath the head.

No part of the body appears to have been covered with a pellicle, except the antennae, and this film now began to shrivel up.

So soon as it had aroused sufficiently from its lethargy, and its limbs had acquired a freer motion, it gradually and occasionally rubbed its tarsi together, as a man would rub his hands, and now and then drew up its legs, especially the hinder ones, as if stretching.

When thus fully developed, it freed itself from its cell, walked out upon the stick about a couple of inches, stood for a second, gave a convulsive shudder, and ejected the me- conium.
