This popular French book on Insects has been placed in my hands in
order that the scientific portions of it should be examined and, if
necessary, corrected. This task has been a light one, for the book had
already passed through the able editorship of Mr. Jansen. But I have
added a short notice of the Thysanoptera, which did not appear in M.
Figuier's original work, and also the necessary information respecting
the evolution of Stylops.
