A SKELETON OF A NEW ARRANGEMENT OF THE FAMILIES, SUBFAMILIES, TRIBES AND GENERA OF THE ANTS, OR THE SUPERFAMILY FORMICOIDEA

Extract

Of the ten superfamilies recognized in my classification of the Hymenoptera, all have been classified down to genera except the Ants, or superfamily IV, Formicoidea, a very large and most difficult complex, and rendered even more difficult by the extraordinary number and diversity of the sexes, there being sometimes several different forms to a single species.
