A resinous substance produced mainly on the banyan tree, but
to some extent on other trees, by the Laccifer lacca
(formerly Coccus lacca), a scale-shaped insect, the female
of which fixes herself on the bark, and exudes from the
margin of her body this resinous substance.

Note: Stick-lac is the substance in its natural state,
incrusting small twigs. When broken off, and the
coloring matter partly removed, the granular residuum
is called seed-lac. When melted, and reduced to a
thin crust, it is called shell-lac or shellac. Lac
is an important ingredient in sealing wax, dyes,
varnishes, and lacquers.
