The correct publication date of the Report upon the collections of Diurnal Lepidoptera Made in Portions of Colorado, Utah, New Mexico, and Arizona by Theodore L. Mead

摘要

In 1871, Theodore L. Mead (1852-1936) (Fig. 1) traveled to Colorado to collect butterflies, mostly for the prominent lepi-dopterist William H. Edwards (1822-1909). Mead later summarized his observations in a treatise entitled Report upon the Collections of Diurnal Lepidoptera Made in Portions of Colorado, Utah, New Mexico, and Arizona, During the Years 1871, 1872, 1873, and 1874, with Notes upon all Species Known to Inhabit Colorado. Based on the title page anddated introductory material in the Report, its year of publication is currently recognized as 1875. New evidence, however, indicates that it was actually published in late 1876.
