The North American species of the broad-nosed weevil genus Pachyrhinus Schnherr 1823 (Coleoptera: Curculionidae, Entiminae) are revised. Three species of Pachyrhinus are here recognized in North America: P. elegans (Couper 1865), P. californicus (Horn 1876), and P. cinereus (Casey 1888). Pachyrhinus lateralis (Casey 1888) and P. miscix (Fall 1901) are here designated as synonyms of P. elegans. Pachyrhinus crassicornis (Casey 1888) and P. albidus (Fall 1901) are here designated synonyms of P. cinereus (Casey 1888) The previously proposed synonymy of P. ferrugineus (Casey 1888) with P. californicus was confirmed. This revision includes detailed images of diagnostic characters as well as scanning electron micrographs of scale morphology for all species. A key to the Nearctic species of Pachyrhinus is provided. All Nearctic species of Pachyrhinus are considered minor pests of Pinus spp. [Pinaceae].
