Dr. W. J. Gertsch provided the distribution data and identified 
P. opifex , Dr. Herbert W. Levi identified the other two species by 
comparing to the types and prepared the diagnostic illustrations. 
Jane E. Thompson, an NSF undergraduate research participant, made 
available her data on nest building. The photographs of P. apacheanus 
displaying are by Dr. G. P. Ginsburg; all other photographs are by 
Dr. Herbert W. Levi. The research was in part supported by Public 
Health Service Research Grants MH-07200 and MH-08938 from
