Abstract
In the literature on forest entomology there has been considerable confusion regarding the true identity of the two species of Dioryctria feeding on spruce in North America. Superficially the adults of these species resemble each other so closely that the one is easily mistaken for the other. In seasonal history and habits, however, they differ very materially.Keywords
