 complete, but it will. I think, be :" ' ' M the 



useful references. So many of " later 



citations are based on erroneous determinations, or are open to 

 suspicion, that I hare even hesita" ' " .' giving ; " _ re 



than original references. 



The following three papers are all that have attempted to deal 

 with our Xorth American fauna in a systematic manner.
