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.
Following the description of each species are notes on its distribution, food habits, etc. The general range or area of distribution given is based not only on the personal collecting of the authors in Florida and their own and adjoining states, but also on the specimens which they have examined in other cabinets and on the published local lists cited in the Bibliography as well as manuscript lists furnished by a number of persons. While it has been the aim to verify, where possible, the names of all doubtful species included in these lists, it has not always been possible to do so and the range as given, especially where it extends beyond our territory, is to be considered as open to correction. The dates of occurrence as given are usually the earliest and latest at which the species has been noted in the locality cited and do not therefore necessarily show the actual time of its appearance or disappearance.
The measurements are given in millimeters or decimals thereof. Since the beak of a weevil is often deflexed or folded beneath the body, the measurement has been taken only from the front margin of the eye or head to the tips of the elytra or pygidium where the latter extends beyond the elytra.
