Two species of undescribed Pselaphidae were discovered during a 
comparison of the fauna of an uncut and a 40 year-old forest. The 
species are described here to provide names for a forthcoming paper 
comparing the pselaphid fauna of these two sites. Holotypes were 
cleared, disarticulated, and mounted on slides in Canada Balsam. 
Both are placed in the Field Museum of Natural History, Chicago. 
All measurements of specimens are in millimeters. 
I would like to thank certain individuals for the loan of speci- 
mens, greatly extending the known ranges of these two new species. 
The abbreviations used to indicate specimen deposition follows the 
individual’s affiliation: Rickard Baranowski, Lund University, 
Sweden (RBC); J. Milton Campbell, Biosystematics Research Insti- 
tute, Ottawa, Canada (CNCI); Michael A. Ivie, Montana State 
University, Bozeman (DZEC); and Alfred F. Newton, Jr., Field 
Museum of Natural History, Chicago (FMNH). Specimens other- 
wise lacking an indication of deposition are in the collections of the 
author and the University of New Hampshire. I would like to thank 
J. F. Burger and R. Marcel Reeves, University of New Hampshire, 
for reviewing the manuscript.
