 simple prefemoral processes. The descendants of such early experimenta- 

 tions survive today in discontinuous ranges as the tribes Orophini and 

 Chonaphini, respectively. 



ACKNOWLEDGEMENTS— Field work for this study was 

 supported by grant number 4495-91 from the National Geographic 

 Society; anatomical examinations took place in January 1992, while I 

 was working at the NMNH on a Mid-Career Fellowship from the 

 National Science Foundation. Access to the types of C. cygneia, 

 michigana, patriotica, and serratus (holotype), Leptodesmus borealis 

 and L. (C.) elrodi, and nontypical material at the NMNH, was courtesy 

 of J. A. Coddington; the type of T. levii and nontypical material at 

 the AMNH were loaned by N. I. Platnick; the holotype of Metaxycheir 

 prolata (UCD) was donated by L. S. Kimsey; paratypes of C. serratus 

 and other samples at the FSCA were provided by G. B. Edwards; and 

 syntypes of Polydesmus armatus (PMNH) were loaned by C. L. Reming- 

 ton and R. J. Pupedis. Samples from the following collections were 

 provided by the indicated curators and collection managers: BYU, R. 

 W. Baumann; CAS, W. J. Pulawski; CMN, P. F. Frank and J. A. 

 Fournier; EIL, R. C. Funk; FMNH, D. A. Summers; MCZ, H. W. 

 Levi; MPM, J. P. Jass; RBCM, R. A. Cannings; ROM. D. C. Darling; 

 SDMNH, D. K. Faulkner; TMM, J. R. Reddell; UBC, S. G. Cannings; 

 UCD, the late R. O. Schuster; UMN, R. Hozenthal; UWBM, R. Crawford; 

 UWY, S. R. Shaw; VMNH, R. L. Hoffman; WSU, R. S. Zack; and 

 WU, D. R. Breakey. My colleague W. A. Shear provided valuable 

 samples from his personal collection, and R. Crawford (UWBM) suggested 

 the name, paraphoena, for the new species of Montaphe. Figures 2- 

 67 were prepared by R. G. Kuhler, NCSM scientific illustrator; Cathy 

 Wood graciously handled repeated word processing chores.
