"We have been greatly interested in running over the pages of this treatise. There is scarcely, in the wide range of natural science, a more interesting or instructive study than that of insects, or one that is calculated to excite more curiosity or wonder.

"The popular form of letters is adopted by the authors in imparting a knowledge of the subject, which renders the work peculiarly fitted for our district school libraries, which are open to all ages and classes."—Hunt's Merchants' Magazine.
