NEW OR LITTLE KNOWN NORTH AMERICAN JAPYGIDAE (THYSANURA)

Extract

There are few North American insects so little known as the members of the family Japygidae. In the United States the entire family has heretofore been represented by hardly a dozen species and from Canada not a single species has yet been recorded. American entomologists have devoted scarcely any attention to the group, and as a consequence, few collections have been made.
