Life History.

The perfect insect is dark coloured, with a tinge of metallic blue, or green, with yellowish or fawn coloured elytra. The page 37 legs are black, also with a blue tinge. It has dark coloured knobs at the ends of the antennae, with only three leaves or folds.

It may be seen in the spring upon limes, willows, beeches, and fruit trees, though not so high up in the trees as the May bug. Towards the end of August the beetles retire to the earth and lay eggs, from which larvæ soon come and attack the roots, remaining in the ground as long, and being transformed in the same manner as those of the larger cockchafer.
