PRE FACE.



THE object of the present Catalogue is to give a complete List of
all the genera and species of Dermaptera Saltatoria known to
exist in the collections of European and American Entomologists.
The letters a, b, c, &c., after the species, denote the specimens now
contained in the British Museum, followed by the habitat and the
mode in which each of them was obtained ; and the absence of
these letters indicates the species which are desiderata, and there-
fore desirable to be procured for the collection.
