Our Common Insects-A Popular Account of the Insects of Our Fields, Forests, Gardens and Houses is a classic insect guide that mainly consists of a reprint of a series of essays which appeared in the "American Naturalist" (Vols. i-v, 1867-71). It is hoped that their perusal may lead to a better acquaintance with the habits and forms of our more common insects. The introduction was written expressly for this book, as well as Chapter XIII, "Hints on the Ancestry of Insects."
