NINE NEW XYSTODESMID MILLIPEDS FROM VIRGINIA 

 AND WEST VIRGINIA, WITH RECORDS OF ESTAB- 



LISHED SPECIES 



By Richard L. Hoffman 



The millipeds reported herein were accumulated largely through 

 field work by the author and by Dr. Horton H. Hobbs, Jr., during 

 the summer of 1947. Five of the species listed were collected near 

 the author's home, in Alleghany County, Va., and four species are 

 due to Dr. Hobbs' field work at Mountain Lake, Va., and in southern 

 West Virginia. The others, with a few exceptions, were obtained on 

 a trip through southwestern Virginia in June and July by Hubert I. 

 Kleinpeter and the author. Lloyd G. Carr sent a number of speci- 

 mens from Augusta County, and Charles M. Wilson and Miss Mar- 

 garet Walton have contributed a large amount of material from 

 Mountain Lake. Individual specimens have been donated by Dr. 

 L. R. Cleveland, Lewis Wright, and Miss Mary Timberlake. 



Of the IG species here listed, 9 are described as new. In addition, 

 records of the occurrence of established species are given, wherever the 

 collections were able to provide new distributional stations. In con- 

 nection with previously described forms, it seemed pertinent to add 

 a citation to the original description as well as to mention the type 

 locality. A brief diagnosis is supplied for each genus — in some cases 

 quoted from the original generic description. 



In previous descriptions of xystodesmids there has been no uniform- 

 ity about the aspects from which the male gonopods have been drawn. 

 I believe that com.parisons of species would be facilitated greatly if
