Abstract
The publication of our recent Check List of the Diurnal Lepidoptera of Boreal America in the Bulletin of the Southern California Academy of Sciences has brought letters asking what part of the nomenclature therein employed deals with the Tentamen. As it would appear that Scudder's fac-simile copies are now unavailable to many workers, we are re-publishing the Tentamen so that its names will be generally available for future discussions.
