At last, entirely collapsed, it forms a mere lining to thewalls of the waxen casket, beneath which the eggs are brought to ma-turity and hatched.

Finally they desert the leaves, and at maturity thegreater number will be found upon the bark of the twigs and smallerbranches. The excretions of wax exude from minute orifices called spinnerets,placed in groups upon various parts of the body, but chiefly upon themargins. At first the wax forms in ridges, which unite and form acrown around a central tuft. Smaller tufts to the number of a dozenor fifteen arise about the central elevation, and the young louse, whenabout a week old, appears as an oval white star upon the leaf The waxgradually spreads over the surface of the insect, and for a time formsdistinct plates; six of these, three upon each side
