I have also specimens from San Angelo, Texas, San Bernardino, Cal- 

 ifornia, and San Antonio, Texas. 



Dr. Alfredo Diigrs has described another species of this geims under 

 the name of R. nntonii.^ It was fonnd at 

 Mazatlan. I have not included species from 

 this region in the present work, as there is 

 doubt as to whether it belongs to the iSTearc- 

 tic or Neotropical faunae I copy Dr. Dngi's's 

 figure for comparison in case the species may 

 be found witliin our limits. 



Bocourt has described a third si)ecics fn- 

 Venezuela under the name of R. thommotii.
