The Insects and Arachnids of Canada Series, Part 25, focuses on a group of Canadian and Alaskan weevils in the subfamily Entiminae. Several species of this broad-nosed weevil subfamily are detrimental to agriculture and forestry. This handbook provides information about 49 genera and 123 species. It includes a key to the subfamilies of the Canadian Curculionidae, a key to the genera of Entiminae, and keys to the species in each genus, where required. The volume describes each species, with observations on weevil biology and host plants, and provides maps illustrating species distribution.

Willis Stanley Blatchley, Charles William Leng. 1916. Rhynchophora or weevils of North Eastern America. Nature Publishing Co., Indianapolis, Indiana. 682 pp.
This work was begun by the senior author, W. S. Blatchley, as a continuation or supplement to his "Coleoptera or Beetles of Indiana,'' published in 1910. After about one-third of the manuscript had been completed the junior author. Chas. W. Leng, wrote that he had a similar work in progress on the Atlantic Coast species of Rhynchophora and proposed that the two works be combined and the geographical scope enlarged so as to include the United States and Canada east of the Mississippi River. After due consideration the arrangement of a joint authorship was agreed upon, the works as begun were merged, enlarged and mostly rewritten, and the book as issued is the result.
