The work includes a key to all the families of Curculionoidea in North America, as well as keys to all genera and species of the families included. [...] The larvae of weevils attack plants from almost every aspect, and it is at this stage that the insects cause the most damage; larvae of broad-nosed Curculionidae generally live free in the soil and feed on roots; larvae of other Curculionidae develop in the roots of herbaceous plants; still others cause galls to form on the roots and stems. [...] In number of species the superfamily Curculionoidea is one of the largest of all the groups of Coleoptera, with an estimated 40 000 species known around the world. [...] The families treated in this part represent only a small fraction of the weevils of Canada and Alaska-only 90 species, compared with the estimated 600 species in Curculionidae, which will be treated in the next two volumes of this study. [...] In Anthribidae and Nemonychidae the maxillary palpi have 4 segments and are flexible, and the labrum is distinct and separate; in the remaining families, the maxillary palpi have 2 or 3 segments and are rigid, and the labrum is never fully free.

Beetles are the largest and most studied order of insects, some of which are beneficial as biological control agents. Alphabetically lists all species and subspecies of beetles known to Canada and Alaska under their respective genus-group names.
